If a directory named by a -I + option is a standard system include directory, the option is + ignored to ensure that the default search order for system + directories and the special treatment of system header files are + not defeated. + * The C and Objective-C compilers no longer accept the "Naming + Types" extension (typedef foo = bar); it was already unavailable + in C++. Code which uses it will need to be changed to use the + "typeof" extension instead: typedef typeof(bar) foo. (We have + removed this extension without a period of deprecation because it + has caused the compiler to crash since version 3.0 and no one + noticed until very recently. Thus we conclude it is not in + widespread use.) + +New Targets and Target Specific Improvements + + IA-32 + + * Fixed a number of bugs in SSE and MMX intrinsics. + * Fixed common compiler crashes with SSE instruction set enabled + (implied by -march=pentium3, pentium4, athlon-xp) + * __m128 and __m128i is not 128bit aligned when used in structures. + + x86-64 + + * A bug whereby the compiler could generate bad code for bzero has + been fixed. + * ABI fixes (implying ABI incompatibilities with previous version in + some corner cases) + * Fixed prefetch code generation + +Bug Fixes + + See [1]this message for a list of bugs fixed in this release. + + Changes in GCC 3.2 + +Bug Fixes + + See [2]this message for a list of bugs fixed in this release. + +Caveats + + * The C++ compiler does not correctly zero-initialize + pointers-to-data members. You must explicitly initialize them. For + example: + int S::*m(0); + + will work, but depending on default-initialization to zero will + not work. This bug cannot be fixed in GCC 3.2 without inducing + unacceptable risks. It will be fixed in GCC 3.3. + * This GCC release is based on the GCC 3.1 sourcebase, and thus has + all the [3]changes in the GCC 3.1 series. In addition, GCC 3.2 has + a number of C++ ABI fixes which make its C++ compiler generate + binary code which is incompatible with the C++ compilers found in + earlier GCC releases, including GCC 3.1 and GCC 3.1.1. + +New Languages and Language specific improvements + + C++ + + * There are now no known differences between the C++ ABI implemented + in GCC and the multi-vendor standard. We believe that the ABI for + the C++ standard library is now stable and will not change in + future versions of the compiler.

Previously the optimization prefetched random + blocks of memory for most targets except for i386. + * The Java compiler now compiles Java programs much faster and also + works with parallel make. + * Nested functions have been fixed for mips*-*-netbsd*. + * Some missing floating point support routines have beed added for + mips*-*-netbsd*. + * This [1]message gives additional information about the bugs fixed + in this release. + +Caveats + + * The -traditional C compiler option has been deprecated and will be + removed in GCC 3.3. (It remains possible to preprocess non-C code + with the traditional preprocessor.) + * The default debugging format for most ELF platforms (including + GNU/Linux and FreeBSD; notable exception is Solaris) has changed + from stabs to DWARF2. This requires GDB 5.1.1 or later. + +General Optimizer Improvements + + * Jan Hubicka, SuSE Labs, together with Richard Henderson, Red Hat, + and Andreas Jaeger, SuSE Labs, has contributed [2]infrastructure + for profile driven optimizations. + Options -fprofile-arcs and -fbranch-probabilities can now be used + to improve speed of the generated code by profiling the actual + program behaviour on typical runs. In the absence of profile info + the compiler attempts to guess the profile statically. + * [3]SPEC2000 and [4]SPEC95 benchmark suites are now used daily to + monitor performance of the generated code. + According to the SPECInt2000 results on an AMD Athlon CPU, the + code generated by GCC 3.1 is 6% faster on the average (8.2% faster + with profile feedback) compared to GCC 3.0. The code produced by + GCC 3.0 is about 2.1% faster compared to 2.95.3. Tests were done + using the -O2 -march=athlon command-line options. + * Alexandre Oliva, of [5]Red Hat, has generalized the tree inlining + infrastructure developed by [6]CodeSourcery, LLC for the C++ front + end, so that it is now used in the C front end too. Inlining + functions as trees exposes them earlier to the compiler, giving it + more opportunities for optimization. + * Support for data prefetching instructions has been added to the + GCC back end and several targets. A new __builtin_prefetch + intrinsic is available to explicitly insert prefetch instructions + and experimental support for loop array prefetching has been added + (see -fprefetch-loop-array documentation). + * Support for emitting debugging information for macros has been + added for DWARF2. It is activated using -g3. + +New Languages and Language specific improvements + + C/C++ + + * A few more [7]ISO C99 features. + * The preprocessor is 10-50% faster than the preprocessor in GCC + 3.0. + * The preprocessor's symbol table has been merged with the symbol + table of the C, C++ and Objective-C front ends. + * The preprocessor consumes less memory than the preprocessor in GCC + 3.0, often significantly so. On normal input files, it typically + consumes less memory than pre-3.0 cccp-based GCC, too. + + C++ + + * -fhonor-std and -fno-honor-std have been removed. -fno-honor-std + was a workaround to allow std compliant code to work with the + non-std compliant libstdc++-v2. libstdc++-v3 is std compliant. + * The C++ ABI has been fixed so that void (A::*)() const is mangled + as "M1AKFvvE", rather than "MK1AFvvE" as before. This change only + affects pointer to cv-qualified member function types. + * The C++ ABI has been changed to correctly handle this code: + struct A { + void operator delete[] (void *, size_t); + }; + + struct B : public A { + }; + + new B[10]; + + The amount of storage allocated for the array will be greater than + it was in 3.0, in order to store the number of elements in the + array, so that the correct size can be passed to operator delete[] + when the array is deleted. Previously, the value passed to + operator delete[] was unpredictable. + This change will only affect code that declares a two-argument + operator delete[] with a second parameter of type size_t in a base + class, and does not override that definition in a derived class. + * The C++ ABI has been changed so that: + struct A { + void operator delete[] (void *, size_t); + void operator delete[] (void *); + }; + + does not cause unnecessary storage to be allocated when an array + of A objects is allocated. + This change will only affect code that declares both of these + forms of operator delete[], and declared the two-argument form + before the one-argument form. + * The C++ ABI has been changed so that when a parameter is passed by + value, any cleanup for that parameter is performed in the caller, + as specified by the ia64 C++ ABI, rather than the called function + as before. As a result, classes with a non-trivial destructor but + a trivial copy constructor will be passed and returned by + invisible reference, rather than by bitwise copy as before. + * G++ now supports the "named return value optimization": for code + like + A f () { + A a; + ... + return a; + } + + G++ will allocate a in the return value slot, so that the return + becomes a no-op. For this to work, all return statements in the + function must return the same variable. + * Improvements to the C++ library are listed in [8]the libstdc++-v3 + FAQ. + + Objective-C + + * Annoying linker warnings (due to incorrect code being generated) + have been fixed. + * If a class method cannot be found, the compiler no longer issues a + warning if a corresponding instance method exists in the root + class. + * Forward @protocol declarations have been fixed. + * Loading of categories has been fixed in certain situations (GNU + run time only). + * The class lookup in the run-time library has been rewritten so + that class method dispatch is more than twice as fast as it used + to be (GNU run time only). + + Java + + * libgcj now includes RMI, java.lang.ref.*, javax.naming, and + javax.transaction. + * Property files and other system resources can be compiled into + executables which use libgcj using the new gcj --resource feature. + * libgcj has been ported to more platforms. In particular there is + now a mostly-functional mingw32 (Windows) target port. + * JNI and CNI invocation interfaces were implemented, so + gcj-compiled Java code can now be called from a C/C++ application. + * gcj can now use builtin functions for certain known methods, for + instance Math.cos. + * gcj can now automatically remove redundant array-store checks in + some common cases. + * The --no-store-checks optimization option was added. This can be + used to omit runtime store checks for code which is known not to + throw ArrayStoreException + * The following third party interface standards were added to + libgcj: org.w3c.dom and org.xml.sax. + * java.security has been merged with GNU Classpath. The new package + is now JDK 1.2 compliant, and much more complete. + * A bytecode verifier was added to the libgcj interpreter. + * java.lang.Character was rewritten to comply with the Unicode 3.0 + standard, and improve performance. + * Partial support for many more locales was added to libgcj. + * Socket timeouts have been implemented. + * libgcj has been merged into a single shared library. There are no + longer separate shared libraries for the garbage collector and + zlib. + * Several performance improvements were made to gcj and libgcj: + + Hash synchronization (thin locks) + + A special allocation path for finalizer-free objects + + Thread-local allocation + + Parallel GC, and other GC tweaks + + Fortran + + Fortran improvements are listed in [9]the Fortran documentation. + + Ada + + [10]Ada Core Technologies, Inc, has contributed its GNAT Ada 95 front + end and associated tools. The GNAT compiler fully implements the Ada + language as defined by the ISO/IEC 8652 standard. + + Please note that the integration of the Ada front end is still work in + progress. + +New Targets and Target Specific Improvements + + * Hans-Peter Nilsson has contributed a port to [11]MMIX, the CPU + architecture used in new editions of Donald E. Knuth's The Art of + Computer Programming. + * [12]Axis Communications has contributed its port to the CRIS CPU + architecture, used in the ETRAX system-on-a-chip series. See + [13]Axis' developer site for technical information. + * Alexandre Oliva, of [14]Red Hat, has contributed a port to the + [15]SuperH SH5 64-bit RISC microprocessor architecture, extending + the existing SH port. + * UltraSPARC is fully supported in 64-bit mode. The option -m64 + enables it. + * For compatibility with the Sun compiler #pragma redefine_extname + has been implemented on Solaris. + * The x86 back end has had some noticeable work done to it. + + [16]SuSE Labs developers Jan Hubicka, Bo Thorsen and Andreas + Jaeger have contributed a port to the AMD x86-64 + architecture. For more information on x86-64 see + [17]http://www.x86-64.org. + + The compiler now supports MMX, 3DNow!, SSE, and SSE2 + instructions. Options -mmmx, -m3dnow, -msse, and -msse2 will + enable the respective instruction sets. Intel C++ compatible + MMX/3DNow!/SSE intrinsics are implemented. SSE2 intrinsics + will be added in next major release. + + Following those improvements, targets for Pentium MMX, K6-2, + K6-3, Pentium III, Pentium 4, and Athlon 4 Mobile/XP/MP were + added. Refer to the documentation on -march= and -mcpu= + options for details. + + For those targets that support it, -mfpmath=sse will cause + the compiler to generate SSE/SSE2 instructions for floating + point math instead of x87 instructions. Usually, this will + lead to quicker code -- especially on the Pentium 4. Note + that only scalar floating point instructions are used and GCC + does not exploit SIMD features yet. + + Prefetch support has been added to the Pentium III, Pentium + 4, K6-2, K6-3, and Athlon series. + + Code generated for floating point to integer converisons has + been improved leading to better performance of many 3D + applications. + * The PowerPC back end has added 64-bit PowerPC GNU/Linux support. + * C++ support for AIX has been improved. + * Aldy Hernandez, of [18]Red Hat, Inc has contributed extensions to + the PowerPC port supporting the AltiVec programming model (SIMD). + The support, though presently useful, is experimental and is + expected to stabilize for 3.2. The support is written to conform + to Motorola's AltiVec specs. See -maltivec. + +Obsolete Systems + + Support for a number of older systems has been declared obsolete in + GCC 3.1. Unless there is activity to revive them, the next release of + GCC will have their sources permanently removed. + + All configurations of the following processor architectures have been + declared obsolete: + * MIL-STD-1750A, 1750a-*-* + * AMD A29k, a29k-*-* + * Convex, c*-convex-* + * Clipper, clipper-*-* + * Elxsi, elxsi-*-* + * Intel i860, i860-*-* + * Sun picoJava, pj-*-* and pjl-*-* + * Western Electric 32000, we32k-*-* + + Most configurations of the following processor architectures have been + declared obsolete, but we are preserving a few systems which may have + active developers.

This allows the compiler to assume the strictest aliasing + rules applicable to the language being compiled.

Normally this change is not + visible, but when using -fshort-enums this is an ABI change. + * The undocumented extension that allowed C programs to have a label + at the end of a compound statement has been deprecated and may be + removed in a future version. Programs that now generate a warning + about this may be fixed by adding a null statement (a single + semicolon) after the label. + * The poorly documented extension that allowed string constants in + C, C++ and Objective C to contain unescaped newlines has been + deprecated and may be removed in a future version. Programs using + this extension may be fixed in several ways: the bare newline may + be replaced by \n, or preceded by \n\, or string concatenation may + be used with the bare newline preceded by \n" and " placed at the + start of the next line. + * The Chill compiler is not included in GCC 3.0, because of the lack + of a volunteer to convert it to use garbage collection. + * Certain non-standard iostream methods from earlier versions of + libstdc++ are not included in libstdc++ v3, i.e. filebuf::attach, + ostream::form, and istream::gets.

By providing more accurate information + to the priority based allocator, we get better register + allocation. + * The register reloading phase of the compiler optimizes spill code + much better than in previous releases. + * Some bad interactions between the register allocator and + instruction scheduler have been fixed, resulting in much better + code for certain programs. Additionally, we have tuned the + scheduler in various ways to improve performance of generated code + for some architectures. + * The compiler's branch shortening algorithms have been + significantly improved to work better on targets which align jump + targets. + * The compiler now supports -Os to prefer optimizing for code space + over optimizing for code speed. + * The compiler will now totally eliminate library calls which + compute constant values. This primarily helps targets with no + integer div/mul support and targets without floating point + support. + * The compiler now supports an extensive "--help" option. + * cpplib has been greatly improved and may be suitable for limited + use. + * Memory footprint for the compiler has been significantly reduced + for some pathological cases. + * The time to build EGCS has been improved for certain targets + (particularly the alpha and mips platforms). + * Many infrastructure improvements throughout the compiler, plus the + usual mountain of bugfixes and minor improvements. + * Target dependent improvements: + + SPARC port now includes V8 plus and V9 support as well as + performance tuning for Ultra class machines. The SPARC port + now uses the Haifa scheduler. + + Alpha port has been tuned for the EV6 processor and has an + optimized expansion of memcpy/bzero.

Various improvements throughout + the x86 port to improve performance on Pentium processors. + Conditional move support has been fixed and enabled for PPro + processors. The x86 port also better supports 64bit + operations now. + + MIPS has improved multiply/multiply-add support and now + includes mips16 ISA support. + + M68k has many micro-optimizations and Coldfire fixes. + * Core compiler is based on the GCC development tree from June 9, + 1998, so we have all of the [5]features found in GCC 2.8. + _________________________________________________________________ + + Please send FSF & GNU inquiries & questions to [6]gnu@gnu.org.

Changes since the + EGCS 1.0 release: + * Add support for Red Hat 5.0 Linux and better support for Linux + systems using glibc2. + Many programs failed to link when compiled with EGCS 1.0 on Red + Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1 + should fix these problems. + * Compatibility with both EGCS 1.0 and GCC 2.8 libgcc exception + handling interfaces. + To avoid future compatibility problems, we strongly urge anyone + who is planning on distributing shared libraries that contain C++ + code to upgrade to EGCS 1.0.1 first. + Soon after EGCS 1.0 was released, the GCC developers made some + incompatible changes in libgcc's exception handling interfaces. + These changes were needed to solve problems on some platforms. + This means that GCC 2.8.0, when released, will not be seamlessly + compatible with shared libraries built by EGCS 1.0. The reason is + that the libgcc.a in GCC 2.8.0 will not contain a function needed + by the old interface. + The result of this is that there may be compatibility problems + with shared libraries built by EGCS 1.0 when used with GCC 2.8.0. + With EGCS 1.0.1, generated code uses the new (GCC 2.8.0) + interface, and libgcc.a has the support routines for both the old + and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be + freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely + mixed). + The maintainers of GCC 2.x have decided against including seamless + support for the old interface in 2.8.0, since it was never + "official", so to avoid future compatibility problems we recommend + against distributing any shared libraries built by EGCS 1.0 that + contain C++ code (upgrade to 1.0.1 and use that). + * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends. + The x86 changes fix code generation errors exposed when building + glibc2 and the Linux dynamic linker (ld.so). + The hppa change fixes a compiler abort when configured for use + with RTEMS. + The MIPS changes fix problems with the definition of LONG_MAX on + newer systems, allow for command line selection of the target ABI, + and fix one code generation problem. + The rs6000/ppc change fixes some problems with passing structures + to varargs/stdarg functions. + * A few machine independent bugfixes, mostly to fix code generation + errors when building Linux kernels or glibc. + * Fix a few critical exception handling and template bugs in the C++ + compiler. + * Fix Fortran namelist bug on alphas. + * Fix build problems on x86-solaris systems. + + An important goal of EGCS is to allow wide scale testing of new + features and optimizations which are still under development.

It is called a macro processor because it allows +you to define \fImacros\fR, which are brief abbreviations for longer +constructs. +.PP +The C preprocessor is intended to be used only with C, \*(C+, and +Objective-C source code. In the past, it has been abused as a general +text processor. It will choke on input which does not obey C's lexical +rules. For example, apostrophes will be interpreted as the beginning of +character constants, and cause errors. Also, you cannot rely on it +preserving characteristics of the input which are not significant to +C-family languages. If a Makefile is preprocessed, all the hard tabs +will be removed, and the Makefile will not work. +.PP +Having said that, you can often get away with using cpp on things which +are not C. Other Algol-ish programming languages are often safe +(Pascal, Ada, etc.) So is assembly, with caution. \fB\-traditional\fR +mode preserves more white space, and is otherwise more permissive. Many +of the problems can be avoided by writing C or \*(C+ style comments +instead of native language comments, and keeping macros simple. +.PP +Wherever possible, you should use a preprocessor geared to the language +you are writing in. Modern versions of the \s-1GNU\s0 assembler have macro +facilities. Most high level programming languages have their own +conditional compilation and inclusion mechanism. If all else fails, +try a true general text processor, such as \s-1GNU\s0 M4. +.PP +C preprocessors vary in some details. This manual discusses the \s-1GNU\s0 C +preprocessor, which provides a small superset of the features of \s-1ISO\s0 +Standard C. In its default mode, the \s-1GNU\s0 C preprocessor does not do a +few things required by the standard. These are features which are +rarely, if ever, used, and may cause surprising changes to the meaning +of a program which does not expect them. To get strict \s-1ISO\s0 Standard C, +you should use the \fB\-std=c89\fR or \fB\-std=c99\fR options, depending +on which version of the standard you want. To get all the mandatory +diagnostics, you must also use \fB\-pedantic\fR. +.SH "OPTIONS" +.IX Header "OPTIONS" +The C preprocessor expects two file names as arguments, \fIinfile\fR and +\&\fIoutfile\fR. The preprocessor reads \fIinfile\fR together with any +other files it specifies with \fB#include\fR. All the output generated +by the combined input files is written in \fIoutfile\fR. +.PP +Either \fIinfile\fR or \fIoutfile\fR may be \fB-\fR, which as +\&\fIinfile\fR means to read from standard input and as \fIoutfile\fR +means to write to standard output. Also, if either file is omitted, it +means the same as if \fB-\fR had been specified for that file. +.PP +Unless otherwise noted, or the option ends in \fB=\fR, all options +which take an argument may have that argument appear either immediately +after the option, or with a space between option and argument: +\&\fB\-Ifoo\fR and \fB\-I foo\fR have the same effect. +.PP +Many options have multi-letter names; therefore multiple single-letter +options may \fInot\fR be grouped: \fB\-dM\fR is very different from +\&\fB\-d\ \-M\fR. +.Ip "\fB\-D\fR \fIname\fR" 4 +.IX Item "-D name" +Predefine \fIname\fR as a macro, with definition \f(CW\*(C`1\*(C'\fR. +.Ip "\fB\-D\fR \fIname\fR\fB=\fR\fIdefinition\fR" 4 +.IX Item "-D name=definition" +Predefine \fIname\fR as a macro, with definition \fIdefinition\fR. +There are no restrictions on the contents of \fIdefinition\fR, but if +you are invoking the preprocessor from a shell or shell-like program you +may need to use the shell's quoting syntax to protect characters such as +spaces that have a meaning in the shell syntax. +.Sp +If you wish to define a function-like macro on the command line, write +its argument list with surrounding parentheses before the equals sign +(if any). Parentheses are meaningful to most shells, so you will need +to quote the option. With \fBsh\fR and \fBcsh\fR, +\&\fB\-D'\fR\fIname\fR\fB(\fR\fIargs...\fR\fB)=\fR\fIdefinition\fR\fB'\fR works. +.Sp +\&\fB\-D\fR and \fB\-U\fR options are processed in the order they +are given on the command line. All \fB\-imacros\fR \fIfile\fR and +\&\fB\-include\fR \fIfile\fR options are processed after all +\&\fB\-D\fR and \fB\-U\fR options. +.Ip "\fB\-U\fR \fIname\fR" 4 +.IX Item "-U name" +Cancel any previous definition of \fIname\fR, either built in or +provided with a \fB\-D\fR option. +.Ip "\fB\-undef\fR" 4 +.IX Item "-undef" +Do not predefine any system-specific macros. The common predefined +macros remain defined. +.Ip "\fB\-I\fR \fIdir\fR" 4 +.IX Item "-I dir" +Add the directory \fIdir\fR to the list of directories to be searched +for header files. +.Sp +Directories named by \fB\-I\fR are searched before the standard +system include directories. +.Sp +It is dangerous to specify a standard system include directory in an +\&\fB\-I\fR option. This defeats the special treatment of system +headers +\&. It can also defeat the repairs to buggy system headers which \s-1GCC\s0 +makes when it is installed. +.Ip "\fB\-o\fR \fIfile\fR" 4 +.IX Item "-o file" +Write output to \fIfile\fR. This is the same as specifying \fIfile\fR +as the second non-option argument to \fBcpp\fR. \fBgcc\fR has a +different interpretation of a second non-option argument, so you must +use \fB\-o\fR to specify the output file. +.Ip "\fB\-Wall\fR" 4 +.IX Item "-Wall" +Turns on all optional warnings which are desirable for normal code. At +present this is \fB\-Wcomment\fR and \fB\-Wtrigraphs\fR. Note that +many of the preprocessor's warnings are on by default and have no +options to control them. +.Ip "\fB\-Wcomment\fR" 4 +.IX Item "-Wcomment" +.PD 0 +.Ip "\fB\-Wcomments\fR" 4 +.IX Item "-Wcomments" +.PD +Warn whenever a comment-start sequence \fB/*\fR appears in a \fB/*\fR +comment, or whenever a backslash-newline appears in a \fB//\fR comment. +(Both forms have the same effect.) +.Ip "\fB\-Wtrigraphs\fR" 4 +.IX Item "-Wtrigraphs" +Warn if any trigraphs are encountered. This option used to take effect +only if \fB\-trigraphs\fR was also specified, but now works +independently. Warnings are not given for trigraphs within comments, as +they do not affect the meaning of the program. +.Ip "\fB\-Wtraditional\fR" 4 +.IX Item "-Wtraditional" +Warn about certain constructs that behave differently in traditional and +\&\s-1ISO\s0 C. Also warn about \s-1ISO\s0 C constructs that have no traditional C +equivalent, and problematic constructs which should be avoided. +.Ip "\fB\-Wimport\fR" 4 +.IX Item "-Wimport" +Warn the first time \fB#import\fR is used. +.Ip "\fB\-Wundef\fR" 4 +.IX Item "-Wundef" +Warn whenever an identifier which is not a macro is encountered in an +\&\fB#if\fR directive, outside of \fBdefined\fR. Such identifiers are +replaced with zero. +.Ip "\fB\-Werror\fR" 4 +.IX Item "-Werror" +Make all warnings into hard errors. Source code which triggers warnings +will be rejected. +.Ip "\fB\-Wsystem-headers\fR" 4 +.IX Item "-Wsystem-headers" +Issue warnings for code in system headers. These are normally unhelpful +in finding bugs in your own code, therefore suppressed. If you are +responsible for the system library, you may want to see them. +.Ip "\fB\-w\fR" 4 +.IX Item "-w" +Suppress all warnings, including those which \s-1GNU\s0 \s-1CPP\s0 issues by default. +.Ip "\fB\-pedantic\fR" 4 +.IX Item "-pedantic" +Issue all the mandatory diagnostics listed in the C standard. Some of +them are left out by default, since they trigger frequently on harmless +code. +.Ip "\fB\-pedantic-errors\fR" 4 +.IX Item "-pedantic-errors" +Issue all the mandatory diagnostics, and make all mandatory diagnostics +into errors. This includes mandatory diagnostics that \s-1GCC\s0 issues +without \fB\-pedantic\fR but treats as warnings. +.Ip "\fB\-M\fR" 4 +.IX Item "-M" +Instead of outputting the result of preprocessing, output a rule +suitable for \fBmake\fR describing the dependencies of the main +source file. The preprocessor outputs one \fBmake\fR rule containing +the object file name for that source file, a colon, and the names of all +the included files, including those coming from \fB\-include\fR or +\&\fB\-imacros\fR command line options. +.Sp +Unless specified explicitly (with \fB\-MT\fR or \fB\-MQ\fR), the +object file name consists of the basename of the source file with any +suffix replaced with object file suffix. If there are many included +files then the rule is split into several lines using \fB\e\fR\-newline. +The rule has no commands. +.Sp +This option does not suppress the preprocessor's debug output, such as +\&\fB\-dM\fR. To avoid mixing such debug output with the dependency +rules you should explicitly specify the dependency output file with +\&\fB\-MF\fR, or use an environment variable like +\&\fB\s-1DEPENDENCIES_OUTPUT\s0\fR. Debug output +will still be sent to the regular output stream as normal. +.Sp +Passing \fB\-M\fR to the driver implies \fB\-E\fR. +.Ip "\fB\-MM\fR" 4 +.IX Item "-MM" +Like \fB\-M\fR but do not mention header files that are found in +system header directories, nor header files that are included, +directly or indirectly, from such a header. +.Sp +This implies that the choice of angle brackets or double quotes in an +\&\fB#include\fR directive does not in itself determine whether that +header will appear in \fB\-MM\fR dependency output. This is a +slight change in semantics from \s-1GCC\s0 versions 3.0 and earlier. +.Ip "\fB\-MF\fR \fIfile\fR" 4 +.IX Item "-MF file" +@anchor{\-MF} +When used with \fB\-M\fR or \fB\-MM\fR, specifies a +file to write the dependencies to. If no \fB\-MF\fR switch is given +the preprocessor sends the rules to the same place it would have sent +preprocessed output. +.Sp +When used with the driver options \fB\-MD\fR or \fB\-MMD\fR, +\&\fB\-MF\fR overrides the default dependency output file. +.Ip "\fB\-MG\fR" 4 +.IX Item "-MG" +When used with \fB\-M\fR or \fB\-MM\fR, \fB\-MG\fR says to treat missing +header files as generated files and assume they live in the same +directory as the source file. It suppresses preprocessed output, as a +missing header file is ordinarily an error. +.Sp +This feature is used in automatic updating of makefiles. +.Ip "\fB\-MP\fR" 4 +.IX Item "-MP" +This option instructs \s-1CPP\s0 to add a phony target for each dependency +other than the main file, causing each to depend on nothing. These +dummy rules work around errors \fBmake\fR gives if you remove header +files without updating the \fIMakefile\fR to match. +.Sp +This is typical output: +.Sp +.Vb 1 +\& test.o: test.c test.h +.Ve +.Vb 1 +\& test.h: +.Ve +.Ip "\fB\-MT\fR \fItarget\fR" 4 +.IX Item "-MT target" +Change the target of the rule emitted by dependency generation. By +default \s-1CPP\s0 takes the name of the main input file, including any path, +deletes any file suffix such as \fB.c\fR, and appends the platform's +usual object suffix. The result is the target. +.Sp +An \fB\-MT\fR option will set the target to be exactly the string you +specify. If you want multiple targets, you can specify them as a single +argument to \fB\-MT\fR, or use multiple \fB\-MT\fR options. +.Sp +For example, \fB\-MT\ '$(objpfx)foo.o'\fR might give +.Sp +.Vb 1 +\& $(objpfx)foo.o: foo.c +.Ve +.Ip "\fB\-MQ\fR \fItarget\fR" 4 +.IX Item "-MQ target" +Same as \fB\-MT\fR, but it quotes any characters which are special to +Make. \fB\-MQ\ '$(objpfx)foo.o'\fR gives +.Sp +.Vb 1 +\& $$(objpfx)foo.o: foo.c +.Ve +The default target is automatically quoted, as if it were given with +\&\fB\-MQ\fR. +.Ip "\fB\-MD\fR" 4 +.IX Item "-MD" +\&\fB\-MD\fR is equivalent to \fB\-M \-MF\fR \fIfile\fR, except that +\&\fB\-E\fR is not implied. The driver determines \fIfile\fR based on +whether an \fB\-o\fR option is given. If it is, the driver uses its +argument but with a suffix of \fI.d\fR, otherwise it take the +basename of the input file and applies a \fI.d\fR suffix. +.Sp +If \fB\-MD\fR is used in conjunction with \fB\-E\fR, any +\&\fB\-o\fR switch is understood to specify the dependency output file +(but \f(CW@pxref\fR{\-MF}), but if used without \fB\-E\fR, each \fB\-o\fR +is understood to specify a target object file. +.Sp +Since \fB\-E\fR is not implied, \fB\-MD\fR can be used to generate +a dependency output file as a side-effect of the compilation process. +.Ip "\fB\-MMD\fR" 4 +.IX Item "-MMD" +Like \fB\-MD\fR except mention only user header files, not system +\&\-header files. +.Ip "\fB\-x c\fR" 4 +.IX Item "-x c" +.PD 0 +.Ip "\fB\-x c++\fR" 4 +.IX Item "-x c++" +.Ip "\fB\-x objective-c\fR" 4 +.IX Item "-x objective-c" +.Ip "\fB\-x assembler-with-cpp\fR" 4 +.IX Item "-x assembler-with-cpp" +.PD +Specify the source language: C, \*(C+, Objective-C, or assembly. This has +nothing to do with standards conformance or extensions; it merely +selects which base syntax to expect. If you give none of these options, +cpp will deduce the language from the extension of the source file: +\&\fB.c\fR, \fB.cc\fR, \fB.m\fR, or \fB.S\fR. Some other common +extensions for \*(C+ and assembly are also recognized. If cpp does not +recognize the extension, it will treat the file as C; this is the most +generic mode. +.Sp +\&\fBNote:\fR Previous versions of cpp accepted a \fB\-lang\fR option +which selected both the language and the standards conformance level. +This option has been removed, because it conflicts with the \fB\-l\fR +option. +.Ip "\fB\-std=\fR\fIstandard\fR" 4 +.IX Item "-std=standard" +.PD 0 +.Ip "\fB\-ansi\fR" 4 +.IX Item "-ansi" +.PD +Specify the standard to which the code should conform.

This suppresses things like macro expansion, trigraph +conversion, escaped newline splicing, and processing of most directives. +The preprocessor still recognizes and removes comments, so that you can +pass a file preprocessed with \fB\-C\fR to the compiler without +problems. In this mode the integrated preprocessor is little more than +a tokenizer for the front ends. +.Sp +\&\fB\-fpreprocessed\fR is implicit if the input file has one of the +extensions \fB.i\fR, \fB.ii\fR or \fB.mi\fR.

The ``overall options'' allow you to stop this +process at an intermediate stage. For example, the \fB\-c\fR option +says not to run the linker. Then the output consists of object files +output by the assembler. +.PP +Other options are passed on to one stage of processing. Some options +control the preprocessor and others the compiler itself. Yet other +options control the assembler and linker; most of these are not +documented here, since you rarely need to use any of them. +.PP +Most of the command line options that you can use with \s-1GCC\s0 are useful +for C programs; when an option is only useful with another language +(usually \*(C+), the explanation says so explicitly. If the description +for a particular option does not mention a source language, you can use +that option with all supported languages. +.PP +The \fBgcc\fR program accepts options and file names as operands. Many +options have multi-letter names; therefore multiple single-letter options +may \fInot\fR be grouped: \fB\-dr\fR is very different from \fB\-d\ \-r\fR. +.PP +You can mix options and other arguments. For the most part, the order +you use doesn't matter. Order does matter when you use several options +of the same kind; for example, if you specify \fB\-L\fR more than once, +the directories are searched in the order specified. +.PP +Many options have long names starting with \fB\-f\fR or with +\&\fB\-W\fR\-\-\-for example, \fB\-fforce-mem\fR, +\&\fB\-fstrength-reduce\fR, \fB\-Wformat\fR and so on. Most of +these have both positive and negative forms; the negative form of +\&\fB\-ffoo\fR would be \fB\-fno-foo\fR.

These occur +after the evaluation of a full expression (one which is not part of a +larger expression), after the evaluation of the first operand of a +\&\f(CW\*(C`&&\*(C'\fR, \f(CW\*(C`||\*(C'\fR, \f(CW\*(C`? :\*(C'\fR or \f(CW\*(C`,\*(C'\fR (comma) operator, before a +function is called (but after the evaluation of its arguments and the +expression denoting the called function), and in certain other places. +Other than as expressed by the sequence point rules, the order of +evaluation of subexpressions of an expression is not specified. All +these rules describe only a partial order rather than a total order, +since, for example, if two functions are called within one expression +with no sequence point between them, the order in which the functions +are called is not specified. However, the standards committee have +ruled that function calls do not overlap. +.Sp +It is not specified when between sequence points modifications to the +values of objects take effect. Programs whose behavior depends on this +have undefined behavior; the C standard specifies that ``Between the +previous and next sequence point an object shall have its stored value +modified at most once by the evaluation of an expression. Furthermore, +the prior value shall be read only to determine the value to be +stored.''. If a program breaks these rules, the results on any +particular implementation are entirely unpredictable. +.Sp +Examples of code with undefined behavior are \f(CW\*(C`a = a++;\*(C'\fR, \f(CW\*(C`a[n] += b[n++]\*(C'\fR and \f(CW\*(C`a[i++] = i;\*(C'\fR. Some more complicated cases are not +diagnosed by this option, and it may give an occasional false positive +result, but in general it has been found fairly effective at detecting +this sort of problem in programs. +.Sp +The present implementation of this option only works for C programs. A +future implementation may also work for \*(C+ programs. +.Sp +The C standard is worded confusingly, therefore there is some debate +over the precise meaning of the sequence point rules in subtle cases. +Links to discussions of the problem, including proposed formal +definitions, may be found on our readings page, at +<\fBhttp://gcc.gnu.org/readings.html\fR>. +.Ip "\fB\-Wreturn-type\fR" 4 +.IX Item "-Wreturn-type" +Warn whenever a function is defined with a return-type that defaults to +\&\f(CW\*(C`int\*(C'\fR.

These warnings as well are possible +only in optimizing compilation. +.Sp +The compiler sees only the calls to \f(CW\*(C`setjmp\*(C'\fR. It cannot know +where \f(CW\*(C`longjmp\*(C'\fR will be called; in fact, a signal handler could +call it at any point in the code. As a result, you may get a warning +even when there is in fact no problem because \f(CW\*(C`longjmp\*(C'\fR cannot +in fact be called at the place which would cause a problem. +.Sp +Some spurious warnings can be avoided if you declare all the functions +you use that never return as \f(CW\*(C`noreturn\*(C'\fR. +.Ip "\fB\-Wreorder\fR (\*(C+ only)" 4 +.IX Item "-Wreorder ( only)" +Warn when the order of member initializers given in the code does not +match the order in which they must be executed.

Thus, \fBfoo.o \-lz bar.o\fR searches library \fBz\fR +after file \fIfoo.o\fR but before \fIbar.o\fR.

But if the file that is found is an +ordinary object file, it is linked in the usual fashion.

In other words, when you specify \fB\-nostdlib\fR +or \fB\-nodefaultlibs\fR you should usually specify \fB\-lgcc\fR as well. +This ensures that you have no unresolved references to internal \s-1GCC\s0 +library subroutines.

The most common +of these is when the application wishes to throw and catch exceptions +across different shared libraries. In that case, each of the libraries +as well as the application itself should use the shared \fIlibgcc\fR. +.Sp +Therefore, the G++ and \s-1GCJ\s0 drivers automatically add +\&\fB\-shared-libgcc\fR whenever you build a shared library or a main +executable, because \*(C+ and Java programs typically use exceptions, so +this is the right thing to do. +.Sp +If, instead, you use the \s-1GCC\s0 driver to create shared libraries, you may +find that they will not always be linked with the shared \fIlibgcc\fR. +If \s-1GCC\s0 finds, at its configuration time, that you have a \s-1GNU\s0 linker that +does not support option \fB\*(--eh-frame-hdr\fR, it will link the shared +version of \fIlibgcc\fR into shared libraries by default. Otherwise, +it will take advantage of the linker and optimize away the linking with +the shared version of \fIlibgcc\fR, linking with the static version of +libgcc by default. This allows exceptions to propagate through such +shared libraries, without incurring relocation costs at library load +time. +.Sp +However, if a library or main executable is supposed to throw or catch +exceptions, you must link it using the G++ or \s-1GCJ\s0 driver, as appropriate +for the languages used in the program, or using the option +\&\fB\-shared-libgcc\fR, such that it is linked with the shared +\&\fIlibgcc\fR. +.Ip "\fB\-symbolic\fR" 4 +.IX Item "-symbolic" +Bind references to global symbols when building a shared object.

However, you should +not use this option to add directories that contain vendor-supplied +system header files (use \fB\-isystem\fR for that). If you use more than +one \fB\-I\fR option, the directories are scanned in left-to-right +order; the standard system directories come after. +.Sp +If a standard system include directory, or a directory specified with +\&\fB\-isystem\fR, is also specified with \fB\-I\fR, the \fB\-I\fR +option will be ignored. The directory will still be searched but as a +system directory at its normal position in the system include chain. +This is to ensure that \s-1GCC\s0's procedure to fix buggy system headers and +the ordering for the include_next directive are not inadvertantly changed. +If you really need to change the search order for system directories, +use the \fB\-nostdinc\fR and/or \fB\-isystem\fR options. +.Ip "\fB\-I-\fR" 4 +.IX Item "-I-" +Any directories you specify with \fB\-I\fR options before the \fB\-I-\fR +option are searched only for the case of \fB#include "\fR\fIfile\fR\fB"\fR; +they are not searched for \fB#include <\fR\fIfile\fR\fB>\fR. +.Sp +If additional directories are specified with \fB\-I\fR options after +the \fB\-I-\fR, these directories are searched for all \fB#include\fR +directives.

They also apply to +includes files in the preprocessor, because the compiler translates these +options into \fB\-isystem\fR options for the preprocessor. In this case, +the compiler appends \fBinclude\fR to the prefix. +.Sp +The run-time support file \fIlibgcc.a\fR can also be searched for using +the \fB\-B\fR prefix, if needed. If it is not found there, the two +standard prefixes above are tried, and that is all. The file is left +out of the link if it is not found by those means. +.Sp +Another way to specify a prefix much like the \fB\-B\fR prefix is to use +the environment variable \fB\s-1GCC_EXEC_PREFIX\s0\fR. +.Sp +As a special kludge, if the path provided by \fB\-B\fR is +\&\fI[dir/]stage\fIN\fI/\fR, where \fIN\fR is a number in the range 0 to +9, then it will be replaced by \fI[dir/]include\fR. This is to help +with boot-strapping the compiler. +.Ip "\fB\-specs=\fR\fIfile\fR" 4 +.IX Item "-specs=file" +Process \fIfile\fR after the compiler reads in the standard \fIspecs\fR +file, in order to override the defaults that the \fIgcc\fR driver +program uses when determining what switches to pass to \fIcc1\fR, +\&\fIcc1plus\fR, \fIas\fR, \fIld\fR, etc. More than one +\&\fB\-specs=\fR\fIfile\fR can be specified on the command line, and they +are processed in order, from left to right. +.Sh "Specifying Target Machine and Compiler Version" +.IX Subsection "Specifying Target Machine and Compiler Version" +By default, \s-1GCC\s0 compiles code for the same type of machine that you +are using. However, it can also be installed as a cross-compiler, to +compile for some other type of machine. In fact, several different +configurations of \s-1GCC\s0, for different target machines, can be +installed side by side. Then you specify which one to use with the +\&\fB\-b\fR option. +.PP +In addition, older and newer versions of \s-1GCC\s0 can be installed side +by side. One of them (probably the newest) will be the default, but +you may sometimes wish to use another. +.Ip "\fB\-b\fR \fImachine\fR" 4 +.IX Item "-b machine" +The argument \fImachine\fR specifies the target machine for compilation. +This is useful when you have installed \s-1GCC\s0 as a cross-compiler. +.Sp +The value to use for \fImachine\fR is the same as was specified as the +machine type when configuring \s-1GCC\s0 as a cross-compiler. For +example, if a cross-compiler was configured with \fBconfigure +i386v\fR, meaning to compile for an 80386 running System V, then you +would specify \fB\-b i386v\fR to run that cross compiler. +.Sp +When you do not specify \fB\-b\fR, it normally means to compile for +the same type of machine that you are using. +.Ip "\fB\-V\fR \fIversion\fR" 4 +.IX Item "-V version" +The argument \fIversion\fR specifies which version of \s-1GCC\s0 to run. +This is useful when multiple versions are installed. For example, +\&\fIversion\fR might be \fB2.0\fR, meaning to run \s-1GCC\s0 version 2.0. +.Sp +The default version, when you do not specify \fB\-V\fR, is the last +version of \s-1GCC\s0 that you installed. +.PP +The \fB\-b\fR and \fB\-V\fR options actually work by controlling part of +the file name used for the executable files and libraries used for +compilation. A given version of \s-1GCC\s0, for a given target machine, is +normally kept in the directory \fI/usr/local/lib/gcc-lib/\fImachine\fI/\fIversion\fI\fR. +.PP +Thus, sites can customize the effect of \fB\-b\fR or \fB\-V\fR either by +changing the names of these directories or adding alternate names (or +symbolic links). If in directory \fI/usr/local/lib/gcc-lib/\fR the +file \fI80386\fR is a link to the file \fIi386v\fR, then \fB\-b +80386\fR becomes an alias for \fB\-b i386v\fR. +.PP +In one respect, the \fB\-b\fR or \fB\-V\fR do not completely change +to a different compiler: the top-level driver program \fBgcc\fR +that you originally invoked continues to run and invoke the other +executables (preprocessor, compiler per se, assembler and linker) +that do the real work. However, since no real work is done in the +driver program, it usually does not matter that the driver program +in use is not the one for the specified target. It is common for the +interface to the other executables to change incompatibly between +compiler versions, so unless the version specified is very close to that +of the driver (for example, \fB\-V 3.0\fR with a driver program from \s-1GCC\s0 +version 3.0.1), use of \fB\-V\fR may not work; for example, using +\&\fB\-V 2.95.2\fR will not work with a driver program from \s-1GCC\s0 3.0. +.PP +The only way that the driver program depends on the target machine is +in the parsing and handling of special machine-specific options. +However, this is controlled by a file which is found, along with the +other executables, in the directory for the specified version and +target machine. As a result, a single installed driver program adapts +to any specified target machine, and sufficiently similar compiler +versions. +.PP +The driver program executable does control one significant thing, +however: the default version and target machine. Therefore, you can +install different instances of the driver program, compiled for +different targets or versions, under different names. +.PP +For example, if the driver for version 2.0 is installed as \fBogcc\fR +and that for version 2.1 is installed as \fBgcc\fR, then the command +\&\fBgcc\fR will use version 2.1 by default, while \fBogcc\fR will use +2.0 by default. However, you can choose either version with either +command with the \fB\-V\fR option. +.Sh "Hardware Models and Configurations" +.IX Subsection "Hardware Models and Configurations" +Earlier we discussed the standard option \fB\-b\fR which chooses among +different installed compilers for completely different target +machines, such as \s-1VAX\s0 vs. 68000 vs. 80386. +.PP +In addition, each of these target machine types can have its own +special options, starting with \fB\-m\fR, to choose among various +hardware models or configurations\-\-\-for example, 68010 vs 68020, +floating coprocessor or none. A single installed version of the +compiler can compile for any model or configuration, according to the +options specified. +.PP +Some configurations of the compiler also support additional special +options, usually for compatibility with other compilers on the same +platform. +.PP +These options are defined by the macro \f(CW\*(C`TARGET_SWITCHES\*(C'\fR in the +machine description.

Developers can then determine what kinds of test cases need +to be added to the testsuites to create both better testing and a better +final product. +.PP +You should compile your code without optimization if you plan to use +\&\fBgcov\fR because the optimization, by combining some lines of code +into one function, may not give you as much information as you need to +look for `hot spots' where the code is using a great deal of computer +time.

There can +be multiple branches and calls listed for a single source line if there +are multiple basic blocks that end on that line. In this case, the +branches and calls are each given a number. There is no simple way to map +these branches and calls back to source constructs. In general, though, +the lowest numbered branch or call will correspond to the leftmost construct +on the source line. +.PP +For a branch, if it was executed at least once, then a percentage +indicating the number of times the branch was taken divided by the +number of times the branch was executed will be printed. Otherwise, the +message ``never executed'' is printed. +.PP +For a call, if it was executed at least once, then a percentage +indicating the number of times the call returned divided by the number +of times the call was executed will be printed. This will usually be +100%, but may be less for functions call \f(CW\*(C`exit\*(C'\fR or \f(CW\*(C`longjmp\*(C'\fR, +and thus may not return every time they are called. +.PP +The execution counts are cumulative. If the example program were +executed again without removing the \fI.da\fR file, the count for the +number of times each line in the source was executed would be added to +the results of the previous \fIrun\fR\|(s). This is potentially useful in +several ways. For example, it could be used to accumulate data over a +number of program runs as part of a test verification suite, or to +provide more accurate long-term information over a large number of +program runs. +.PP +The data in the \fI.da\fR files is saved immediately before the program +exits. For each source file compiled with \fB\-fprofile-arcs\fR, the profiling +code first attempts to read in an existing \fI.da\fR file; if the file +doesn't match the executable (differing number of basic block counts) it +will ignore the contents of the file. It then adds in the new execution +counts and finally writes the data to the file. +.Sh "Using \fBgcov\fP with \s-1GCC\s0 Optimization" +.IX Subsection "Using gcov with GCC Optimization" +If you plan to use \fBgcov\fR to help optimize your code, you must +first compile your program with two special \s-1GCC\s0 options: +\&\fB\-fprofile-arcs \-ftest-coverage\fR. Aside from that, you can use any +other \s-1GCC\s0 options; but if you want to prove that every single line +in your program was executed, you should not compile with optimization +at the same time. On some machines the optimizer can eliminate some +simple code lines by combining them with other lines. For example, code +like this: +.PP +.Vb 4 +\& if (a != b) +\& c = 1; +\& else +\& c = 0; +.Ve +can be compiled into one instruction on some machines. In this case, +there is no way for \fBgcov\fR to calculate separate execution counts +for each line because there isn't separate code for each line. Hence +the \fBgcov\fR output looks like this if you compiled the program with +optimization: +.PP +.Vb 4 +\& 100 if (a != b) +\& 100 c = 1; +\& 100 else +\& 100 c = 0; +.Ve +The output shows that this block of code, combined by optimization, +executed 100 times. In one sense this result is correct, because there +was only one instruction representing all four of these lines. However, +the output does not indicate how many times the result was 0 and how +many times the result was 1. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fIgpl\fR\|(7), \fIgfdl\fR\|(7), \fIfsf-funding\fR\|(7), \fIgcc\fR\|(1) and the Info entry for \fIgcc\fR. +.SH "COPYRIGHT" +.IX Header "COPYRIGHT" +Copyright (c) 1996, 1997, 1999, 2000, 2001 Free Software Foundation, Inc. +.PP +Permission is granted to copy, distribute and/or modify this document +under the terms of the \s-1GNU\s0 Free Documentation License, Version 1.1 or +any later version published by the Free Software Foundation; with the +Invariant Sections being ``\s-1GNU\s0 General Public License'' and ``Funding +Free Software'', the Front-Cover texts being (a) (see below), and with +the Back-Cover Texts being (b) (see below).

This includes bugs that are actually in +the `gcc' back end (GBE) or in `libf2c', because those sets of code are +at least somewhat under the control of (and necessarily intertwined +with) `g77', so it isn't worth separating them out. + + For information on bugs in _other_ versions of `g77', see +`gcc/gcc/f/NEWS'. There, lists of bugs fixed in various versions of +`g77' can help determine what bugs existed in prior versions. + + An online, "live" version of this document (derived directly from +the mainline, development version of `g77' within `gcc') is available +via `http://www.gnu.org/software/gcc/onlinedocs/g77/Trouble.html'. +Follow the "Known Bugs" link. + + The following information was last updated on 2002-02-01: + + * `g77' fails to warn about use of a "live" iterative-DO variable as + an implied-DO variable in a `WRITE' or `PRINT' statement (although + it does warn about this in a `READ' statement). + + * Something about `g77''s straightforward handling of label + references and definitions sometimes prevents the GBE from + unrolling loops. Until this is solved, try inserting or removing + `CONTINUE' statements as the terminal statement, using the `END DO' + form instead, and so on. + + * Some confusion in diagnostics concerning failing `INCLUDE' + statements from within `INCLUDE''d or `#include''d files. + + * `g77' assumes that `INTEGER(KIND=1)' constants range from `-2**31' + to `2**31-1' (the range for two's-complement 32-bit values), + instead of determining their range from the actual range of the + type for the configuration (and, someday, for the constant). + + Further, it generally doesn't implement the handling of constants + very well in that it makes assumptions about the configuration + that it no longer makes regarding variables (types). + + Included with this item is the fact that `g77' doesn't recognize + that, on IEEE-754/854-compliant systems, `0./0.' should produce a + NaN and no warning instead of the value `0.' and a warning. + + * `g77' uses way too much memory and CPU time to process large + aggregate areas having any initialized elements. + + For example, `REAL A(1000000)' followed by `DATA A(1)/1/' takes up + way too much time and space, including the size of the generated + assembler file. + + Version 0.5.18 improves cases like this--specifically, cases of + _sparse_ initialization that leave large, contiguous areas + uninitialized--significantly. However, even with the + improvements, these cases still require too much memory and CPU + time. + + (Version 0.5.18 also improves cases where the initial values are + zero to a much greater degree, so if the above example ends with + `DATA A(1)/0/', the compile-time performance will be about as good + as it will ever get, aside from unrelated improvements to the + compiler.) + + Note that `g77' does display a warning message to notify the user + before the compiler appears to hang. + + * When debugging, after starting up the debugger but before being + able to see the source code for the main program unit, the user + must currently set a breakpoint at `MAIN__' (or `MAIN___' or + `MAIN_' if `MAIN__' doesn't exist) and run the program until it + hits the breakpoint. At that point, the main program unit is + activated and about to execute its first executable statement, but + that's the state in which the debugger should start up, as is the + case for languages like C. + + * Debugging `g77'-compiled code using debuggers other than `gdb' is + likely not to work. + + Getting `g77' and `gdb' to work together is a known + problem--getting `g77' to work properly with other debuggers, for + which source code often is unavailable to `g77' developers, seems + like a much larger, unknown problem, and is a lower priority than + making `g77' and `gdb' work together properly. + + On the other hand, information about problems other debuggers have + with `g77' output might make it easier to properly fix `g77', and + perhaps even improve `gdb', so it is definitely welcome. Such + information might even lead to all relevant products working + together properly sooner. + + * `g77' doesn't work perfectly on 64-bit configurations such as the + Digital Semiconductor ("DEC") Alpha. + + This problem is largely resolved as of version 0.5.23. + + * `g77' currently inserts needless padding for things like `COMMON + A,IPAD' where `A' is `CHARACTER*1' and `IPAD' is `INTEGER(KIND=1)' + on machines like x86, because the back end insists that `IPAD' be + aligned to a 4-byte boundary, but the processor has no such + requirement (though it is usually good for performance). + + The `gcc' back end needs to provide a wider array of + specifications of alignment requirements and preferences for + targets, and front ends like `g77' should take advantage of this + when it becomes available. + + * The `libf2c' routines that perform some run-time arithmetic on + `COMPLEX' operands were modified circa version 0.5.20 of `g77' to + work properly even in the presence of aliased operands. + + While the `g77' and `netlib' versions of `libf2c' differ on how + this is accomplished, the main differences are that we believe the + `g77' version works properly even in the presence of _partially_ + aliased operands. + + However, these modifications have reduced performance on targets + such as x86, due to the extra copies of operands involved. + diff --git a/contrib/gcc/f/ChangeLog b/contrib/gcc/f/ChangeLog index 3f3b286..729cfc9d 100644 --- a/contrib/gcc/f/ChangeLog +++ b/contrib/gcc/f/ChangeLog @@ -1,3 +1,22 @@ +2002-11-19 Release Manager + + * GCC 3.2.1 Released. + +2002-11-19 Release Manager + + * GCC 3.2.1 Released. + +2002-11-18 Release Manager + + * GCC 3.2.1 Released. + +2002-10-28 Andris Pavenis <pavenis@latnet.lv> + Toon Moene <toon@moene.indiv.nluug.nl> + + PR fortran/8308 + * lang-specs.h: Correct ratfor specs. + * news.texi: Document this fix. + 2002-09-14 Hans-Peter Nilsson <hp@bitrange.com> * target.c (ffetarget_memcpy_): Don't test nonexistent diff --git a/contrib/gcc/f/NEWS b/contrib/gcc/f/NEWS new file mode 100644 index 0000000..cc73668 --- /dev/null +++ b/contrib/gcc/f/NEWS @@ -0,0 +1,531 @@ +_Note:_ This file is automatically generated from the files +`news0.texi' and `news.texi'. `NEWS' is _not_ a source file, although +it is normally included within source distributions. + + This file lists news about the GCC-3.2 version (and some other +versions) of the GNU Fortran compiler.

Note: On GNU/Linux + systems one has to compile programs that occupy more than 1 Gbyte + statically, i.e. `g77 -static ...'. + + * Based on work done by Juergen Pfeifer (<juergen.pfeifer@gmx.net>) + libf2c is now a shared library.

This has been + fixed by using the `ftruncate' OS function. Thanks go to the + GAMESS developers for bringing this to our attention. + + * Using options `-g', `-ggdb' or `-gdwarf[-2]' (where appropriate + for your target) now also enables debugging information for COMMON + BLOCK and EQUIVALENCE items to be emitted. Thanks go to Andrew + Vaught (<andy@xena.eas.asu.edu>) and George Helffrich + (<george@geology.bristol.ac.uk>) for fixing this longstanding + problem. + + * It is not necessary anymore to use the option `-femulate-complex' + to compile Fortran code using COMPLEX arithmetic, even on 64-bit + machines (like the Alpha). This will improve code generation. + + * INTRINSIC arithmetic functions are now treated as routines that do + not depend on anything but their argument(s). This enables + further instruction scheduling, because it is known that they + cannot read or modify arbitrary locations. + + * Upgrade to `libf2c' as of 2000-12-05. + + This fixes a bug where a namelist containing initialization of + LOGICAL items and a variable starting with T or F would be read + incorrectly. + + * The `TtyNam' intrinsics now set NAME to all spaces (at run time) + if the system has no `ttyname' implementation available. + + * Upgrade to `libf2c' as of 1999-06-28. + + This fixes a bug whereby input to a `NAMELIST' read involving a + repeat count, such as `K(5)=10*3', was not properly handled by + `libf2c'. The first item was written to `K(5)', but the remaining + nine were written elsewhere (still within the array), not + necessarily starting at `K(6)'. + +In 0.5.25, `GCC' 2.95 (`EGCS' 1.2) versus `EGCS' 1.1.2: +======================================================= + + * `g77' no longer generates bad code for assignments, or other + conversions, of `REAL' or `COMPLEX' constant expressions to type + `INTEGER(KIND=2)' (often referred to as `INTEGER*8'). + + For example, `INTEGER*8 J; J = 4E10' now works as documented. + + * `g77' no longer truncates `INTEGER(KIND=2)' (usually `INTEGER*8') + subscript expressions when evaluating array references on systems + with pointers widers than `INTEGER(KIND=1)' (such as Alphas). + + * `g77' no longer generates bad code for an assignment to a + `COMPLEX' variable or array that partially overlaps one or more of + the sources of the same assignment (a very rare construction). It + now assigns through a temporary, in cases where such partial + overlap is deemed possible. + + * `libg2c' (`libf2c') no longer loses track of the file being worked + on during a `BACKSPACE' operation. + + * `libg2c' (`libf2c') fixes a bug whereby input to a `NAMELIST' read + involving a repeat count, such as `K(5)=10*3', was not properly + handled by `libf2c'. The first item was written to `K(5)', but + the remaining nine were written elsewhere (still within the array), + not necessarily starting at `K(6)'. + + * Automatic arrays now seem to be working on HP-UX systems. + + * The `Date' intrinsic now returns the correct result on big-endian + systems. + + * Fix `g77' so it no longer crashes when compiling I/O statements + using keywords that define `INTEGER' values, such as `IOSTAT=J', + where J is other than default `INTEGER' (such as `INTEGER*2'). + Instead, it issues a diagnostic. + + * Fix `g77' so it properly handles `DATA A/RPT*VAL/', where RPT is + not default `INTEGER', such as `INTEGER*2', instead of producing a + spurious diagnostic. Also fix `DATA (A(I),I=1,N)', where `N' is + not default `INTEGER' to work instead of crashing `g77'. + + * The `-ax' option is now obeyed when compiling Fortran programs. + (It is passed to the `f771' driver.) + + * The new `-fbounds-check' option causes `g77' to compile run-time + bounds checks of array subscripts, as well as of substring start + and end points. + + * `libg2c' now supports building as multilibbed library, which + provides better support for systems that require options such as + `-mieee' to work properly. + + * Source file names with the suffixes `.FOR' and `.FPP' now are + recognized by `g77' as if they ended in `.for' and `.fpp', + respectively. + + * The order of arguments to the _subroutine_ forms of the `CTime', + `DTime', `ETime', and `TtyNam' intrinsics has been swapped. The + argument serving as the returned value for the corresponding + function forms now is the _second_ argument, making these + consistent with the other subroutine forms of `libU77' intrinsics. + + * `g77' now warns about a reference to an intrinsic that has an + interface that is not Year 2000 (Y2K) compliant. Also, `libg2c' + has been changed to increase the likelihood of catching references + to the implementations of these intrinsics using the `EXTERNAL' + mechanism (which would avoid the new warnings). + + * `g77' now warns about a reference to a function when the + corresponding _subsequent_ function program unit disagrees with + the reference concerning the type of the function. + + * `-fno-emulate-complex' is now the default option. This should + result in improved performance of code that uses the `COMPLEX' + data type. + + * The `-malign-double' option now reliably aligns _all_ + double-precision variables and arrays on Intel x86 targets. + + * Even without the `-malign-double' option, `g77' reliably aligns + local double-precision variables that are not in `EQUIVALENCE' + areas and not `SAVE''d. + + * `g77' now open-codes ("inlines") division of `COMPLEX' operands + instead of generating a run-time call to the `libf2c' routines + `c_div' or `z_div', unless the `-Os' option is specified. + + * `g77' no longer generates code to maintain `errno', a C-language + concept, when performing operations such as the `SqRt' intrinsic. + + * `g77' developers can temporarily use the `-fflatten-arrays' option + to compare how the compiler handles code generation using C-like + constructs as compared to the Fortran-like method constructs + normally used. + + * A substantial portion of the `g77' front end's code-generation + component was rewritten. It now generates code using facilities + more robustly supported by the `gcc' back end. One effect of this + rewrite is that some codes no longer produce a spurious "label LAB + used before containing binding contour" message. + + * Support for the `-fugly' option has been removed. + + * Improve documentation and indexing, including information on Year + 2000 (Y2K) compliance, and providing more information on internals + of the front end. + + * Upgrade to `libf2c' as of 1999-05-10. + +In 0.5.24 versus 0.5.23: +======================== + + There is no `g77' version 0.5.24 at this time, or planned. 0.5.24 +is the version number designated for bug fixes and, perhaps, some new +features added, to 0.5.23. Version 0.5.23 requires `gcc' 2.8.1, as +0.5.24 was planned to require. + + Due to `EGCS' becoming `GCC' (which is now an acronym for "GNU +Compiler Collection"), and `EGCS' 1.2 becoming officially designated +`GCC' 2.95, there seems to be no need for an actual 0.5.24 release. + + To reduce the confusion already resulting from use of 0.5.24 to +designate `g77' versions within `EGCS' versions 1.0 and 1.1, as well as +in versions of `g77' documentation and notices during that period, +"mainline" `g77' version numbering resumes at 0.5.25 with `GCC' 2.95 +(`EGCS' 1.2), skipping over 0.5.24 as a placeholder version number. + + To repeat, there is no `g77' 0.5.24, but there is now a 0.5.25. +Please remain calm and return to your keypunch units. + +In `EGCS' 1.1.2 versus `EGCS' 1.1.1: +==================================== + + * Fix the `IDate' intrinsic (VXT) (in `libg2c') so the returned year + is in the documented, non-Y2K-compliant range of 0-99, instead of + being returned as 100 in the year 2000. + + * Fix the `Date_and_Time' intrinsic (in `libg2c') to return the + milliseconds value properly in VALUES(8). + + * Fix the `LStat' intrinsic (in `libg2c') to return device-ID + information properly in SARRAY(7). + + * Improve documentation. + +In `EGCS' 1.1.1 versus `EGCS' 1.1: +================================== + + * Fix `libg2c' so it performs an implicit `ENDFILE' operation (as + appropriate) whenever a `REWIND' is done. + + (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s + version of `libf2c'.) + + * Fix `libg2c' so it no longer crashes with a spurious diagnostic + upon doing any I/O following a direct formatted write. + + (This bug was introduced in 0.5.23 and `egcs' 1.1 in `g77''s + version of `libf2c'.) + + * Fix `g77' so it no longer crashes compiling references to the + `Rand' intrinsic on some systems. + + * Fix `g77' portion of installation process so it works better on + some systems (those with shells requiring `else true' clauses on + `if' constructs for the completion code to be set properly). + +In `EGCS' 1.1 versus `EGCS' 1.0.3: +================================== + + * Fix bugs in the `libU77' intrinsic `HostNm' that wrote one byte + beyond the end of its `CHARACTER' argument, and in the `libU77' + intrinsics `GMTime' and `LTime' that overwrote their arguments. + + * Assumed arrays with negative bounds (such as `REAL A(-1:*)') no + longer elicit spurious diagnostics from `g77', even on systems + with pointers having different sizes than integers. + + This bug is not known to have existed in any recent version of + `gcc'. It was introduced in an early release of `egcs'. + + * Valid combinations of `EXTERNAL', passing that external as a dummy + argument without explicitly giving it a type, and, in a subsequent + program unit, referencing that external as an external function + with a different type no longer crash `g77'. + + * `CASE DEFAULT' no longer crashes `g77'. + + * The `-Wunused' option no longer issues a spurious warning about + the "master" procedure generated by `g77' for procedures + containing `ENTRY' statements. + + * Support `FORMAT(I<EXPR>)' when EXPR is a compile-time constant + `INTEGER' expression. + + * Fix `g77' `-g' option so procedures that use `ENTRY' can be + stepped through, line by line, in `gdb'. + + * Allow any `REAL' argument to intrinsics `Second' and `CPU_Time'. + + * Use `tempnam', if available, to open scratch files (as in + `OPEN(STATUS='SCRATCH')') so that the `TMPDIR' environment + variable, if present, is used. + + * `g77''s version of `libf2c' separates out the setting of global + state (such as command-line arguments and signal handling) from + `main.o' into distinct, new library archive members. + + This should make it easier to write portable applications that + have their own (non-Fortran) `main()' routine properly set up the + `libf2c' environment, even when `libf2c' (now `libg2c') is a + shared library. + + * `g77' no longer installs the `f77' command and `f77.1' man page in + the `/usr' or `/usr/local' hierarchy, even if the `f77-install-ok' + file exists in the source or build directory. See the + installation documentation for more information. + + * `g77' no longer installs the `libf2c.a' library and `f2c.h' + include file in the `/usr' or `/usr/local' hierarchy, even if the + `f2c-install-ok' or `f2c-exists-ok' files exist in the source or + build directory. See the installation documentation for more + information. + + * The `libf2c.a' library produced by `g77' has been renamed to + `libg2c.a'. It is installed only in the `gcc' "private" directory + hierarchy, `gcc-lib'. This allows system administrators and users + to choose which version of the `libf2c' library from `netlib' they + wish to use on a case-by-case basis. See the installation + documentation for more information. + + * The `f2c.h' include (header) file produced by `g77' has been + renamed to `g2c.h'. It is installed only in the `gcc' "private" + directory hierarchy, `gcc-lib'. This allows system administrators + and users to choose which version of the include file from + `netlib' they wish to use on a case-by-case basis. See the + installation documentation for more information. + + * The `g77' command now expects the run-time library to be named + `libg2c.a' instead of `libf2c.a', to ensure that a version other + than the one built and installed as part of the same `g77' version + is picked up. + + * During the configuration and build process, `g77' creates + subdirectories it needs only as it needs them. Other cleaning up + of the configuration and build process has been performed as well. + + * `install-info' now used to update the directory of Info + documentation to contain an entry for `g77' (during installation). + + * Some diagnostics have been changed from warnings to errors, to + prevent inadvertent use of the resulting, probably buggy, programs. + These mostly include diagnostics about use of unsupported features + in the `OPEN', `INQUIRE', `READ', and `WRITE' statements, and + about truncations of various sorts of constants. + + * Improve compilation of `FORMAT' expressions so that a null byte is + appended to the last operand if it is a constant. This provides a + cleaner run-time diagnostic as provided by `libf2c' for statements + like `PRINT '(I1', 42'. + + * Improve documentation and indexing. + + * The upgrade to `libf2c' as of 1998-06-18 should fix a variety of + problems, including those involving some uses of the `T' format + specifier, and perhaps some build (porting) problems as well. + +In `EGCS' 1.1 versus `g77' 0.5.23: +================================== + + * Fix a code-generation bug that afflicted Intel x86 targets when + `-O2' was specified compiling, for example, an old version of the + `DNRM2' routine. + + The x87 coprocessor stack was being mismanaged in cases involving + assigned `GOTO' and `ASSIGN'. + + * `g77' no longer produces incorrect code and initial values for + `EQUIVALENCE' and `COMMON' aggregates that, due to "unnatural" + ordering of members vis-a-vis their types, require initial padding. + + * Fix `g77' crash compiling code containing the construct + `CMPLX(0.)' or similar. + + * `g77' no longer crashes when compiling code containing + specification statements such as `INTEGER(KIND=7) PTR'. + + * `g77' no longer crashes when compiling code such as `J = SIGNAL(1, + 2)'. + + * `g77' now treats `%LOC(EXPR)' and `LOC(EXPR)' as "ordinary" + expressions when they are used as arguments in procedure calls. + This change applies only to global (filewide) analysis, making it + consistent with how `g77' actually generates code for these cases. + + Previously, `g77' treated these expressions as denoting special + "pointer" arguments for the purposes of filewide analysis. + + * Fix `g77' crash (or apparently infinite run-time) when compiling + certain complicated expressions involving `COMPLEX' arithmetic + (especially multiplication). + + * Align static double-precision variables and arrays on Intel x86 + targets regardless of whether `-malign-double' is specified. + + Generally, this affects only local variables and arrays having the + `SAVE' attribute or given initial values via `DATA'. + + * The `g77' driver now ensures that `-lg2c' is specified in the link + phase prior to any occurrence of `-lm'. This prevents + accidentally linking to a routine in the SunOS4 `-lm' library when + the generated code wants to link to the one in `libf2c' (`libg2c'). + + * `g77' emits more debugging information when `-g' is used. + + This new information allows, for example, `which __g77_length_a' + to be used in `gdb' to determine the type of the phantom length + argument supplied with `CHARACTER' variables. + + This information pertains to internally-generated type, variable, + and other information, not to the longstanding deficiencies + vis-a-vis `COMMON' and `EQUIVALENCE'. + + * The F90 `Date_and_Time' intrinsic now is supported. + + * The F90 `System_Clock' intrinsic allows the optional arguments + (except for the `Count' argument) to be omitted. + + * Upgrade to `libf2c' as of 1998-06-18. + + * Improve documentation and indexing. + +In previous versions: +===================== + + Information on previous versions is not provided in this +`gcc/gcc/f/NEWS' file, to keep it short.

Another, public domain version in C is at +<\fBhttp://sepwww.stanford.edu/sep/prof/ratfor.shar.2\fR>. +.PP +\&\s-1UNIX\s0 users typically use the \fI\fIfile\fI.f\fR and \fI\fIfile\fI.F\fR +nomenclature. +Users of other operating systems, especially those that cannot +distinguish upper-case +letters from lower-case letters in their file names, typically use +the \fI\fIfile\fI.for\fR and \fI\fIfile\fI.fpp\fR nomenclature. +.PP +Use of the preprocessor \fBcpp\fR allows use of C-like +constructs such as \f(CW\*(C`#define\*(C'\fR and \f(CW\*(C`#include\*(C'\fR, but can +lead to unexpected, even mistaken, results due to Fortran's source file +format. +It is recommended that use of the C preprocessor +be limited to \f(CW\*(C`#include\*(C'\fR and, in +conjunction with \f(CW\*(C`#define\*(C'\fR, only \f(CW\*(C`#if\*(C'\fR and related directives, +thus avoiding in-line macro expansion entirely. +This recommendation applies especially +when using the traditional fixed source form. +With free source form, +fewer unexpected transformations are likely to happen, but use of +constructs such as Hollerith and character constants can nevertheless +present problems, especially when these are continued across multiple +source lines. +These problems result, primarily, from differences between the way +such constants are interpreted by the C preprocessor and by a Fortran +compiler. +.PP +Another example of a problem that results from using the C preprocessor +is that a Fortran comment line that happens to contain any +characters ``interesting'' to the C preprocessor, +such as a backslash at the end of the line, +is not recognized by the preprocessor as a comment line, +so instead of being passed through ``raw'', +the line is edited according to the rules for the preprocessor. +For example, the backslash at the end of the line is removed, +along with the subsequent newline, resulting in the next +line being effectively commented out\-\-\-unfortunate if that +line is a non-comment line of important code! +.PP +\&\fINote:\fR The \fB\-traditional\fR and \fB\-undef\fR flags are supplied +to \fBcpp\fR by default, to help avoid unpleasant surprises. +.PP +This means that \s-1ANSI\s0 C preprocessor features (such as the \fB#\fR +operator) aren't available, and only variables in the C reserved +namespace (generally, names with a leading underscore) are liable to +substitution by C predefines. +Thus, if you want to do system-specific +tests, use, for example, \fB#ifdef _\|_linux_\|_\fR rather than \fB#ifdef linux\fR. +Use the \fB\-v\fR option to see exactly how the preprocessor is invoked. +.PP +Unfortunately, the \fB\-traditional\fR flag will not avoid an error from +anything that \fBcpp\fR sees as an unterminated C comment, such as: +.PP +.Vb 2 +\& C Some Fortran compilers accept /* as starting +\& C an inline comment. +.Ve +The following options that affect overall processing are recognized +by the \fBg77\fR
