Rename vendor/binutils/*/contrib to vendor/binutils/*/x
Binutils has a "contrib" subdirectory - thus flattening cannot happen
without renaming the upper level contrib directory in a first pass.
Also, don't record this move and remove any keyword expansion.

The old method of specifying the - target processor has been deprecated, but is still accepted for - compatibility. - -* Support for the VFP floating-point instruction set has been added to - the ARM assembler. - -* New psuedo op: .incbin to include a set of binary data at a given point - in the assembly. Contributed by Anders Norlander. - -* The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated - but still works for compatability. - -* The MIPS assembler no longer issues a warning by default when it - generates a nop instruction from a macro. The new command line option - -n will turn on the warning. - -Changes in 2.11: - -* Support for PDP-11 and 2.11BSD a.out format, by Lars Brinkhoff. - -* x86 gas now supports the full Pentium4 instruction set. - -* Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs. - -* Support for Motorola 68HC11 and 68HC12. - -* Support for Texas Instruments TMS320C54x (tic54x). - -* Support for IA-64. - -* Support for i860, by Jason Eckhardt. - -* Support for CRIS (Axis Communications ETRAX series). - -* x86 gas has a new .arch pseudo op to specify the target CPU architecture. - -* x86 gas -q command line option quietens warnings about register size changes - due to suffix, indirect jmp/call without `*', stand-alone prefixes, and - translating various deprecated floating point instructions. - -Changes in 2.10: - -* Support for the ARM msr instruction was changed to only allow an immediate - operand when altering the flags field. - -* Support for ATMEL AVR. - -* Support for IBM 370 ELF. Somewhat experimental. - -* Support for numbers with suffixes. - -* Added support for breaking to the end of repeat loops. - -* Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL). - -* New .elseif pseudo-op added. - -* New --fatal-warnings option. - -* picoJava architecture support added. - -* Motorola MCore 210 processor support added. - -* A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386 - assembly programs with intel syntax. - -* New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. - -* Added -gdwarf2 option to generate DWARF 2 debugging information. - -* Full 16-bit mode support for i386. - -* Greatly improved instruction operand checking for i386. This change will - produce errors or warnings on incorrect assembly code that previous versions - of gas accepted. If you get unexpected messages from code that worked with - older versions of gas, please double check the code before reporting a bug. - -* Weak symbol support added for COFF targets. - -* Mitsubishi D30V support added. - -* Texas Instruments c80 (tms320c80) support added. - -* i960 ELF support added. - -* ARM ELF support added. - -Changes in 2.9: - -* Texas Instruments c30 (tms320c30) support added. - -* The assembler now optimizes the exception frame information generated by egcs - and gcc 2.8. The new --traditional-format option disables this optimization. - -* Added --gstabs option to generate stabs debugging information. - -* The -a option takes a new suboption, m (e.g., -alm) to expand macros in a - listing. - -* Added -MD option to print dependencies. - -Changes in 2.8: - -* BeOS support added. - -* MIPS16 support added. - -* Motorola ColdFire 5200 support added (configure for m68k and use -m5200). - -* Alpha/VMS support added. - -* m68k options --base-size-default-16, --base-size-default-32, - --disp-size-default-16, and --disp-size-default-32 added. - -* The alignment directives now take an optional third argument, which is the - maximum number of bytes to skip. If doing the alignment would require - skipping more than the given number of bytes, the alignment is not done at - all. - -* The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. - -* The -a option takes a new suboption, c (e.g., -alc), to skip false - conditionals in listings. - -* Added new pseudo-op, .equiv; it's like .equ, except that it is an error if - the symbol is already defined. - -Changes in 2.7: - -* The PowerPC assembler now allows the use of symbolic register names (r0, - etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) - can be used any time. PowerPC 860 move to/from SPR instructions have been - added. - -* Alpha Linux (ELF) support added. - -* PowerPC ELF support added. - -* m68k Linux (ELF) support added. - -* i960 Hx/Jx support added. - -* i386/PowerPC gnu-win32 support added. - -* SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the - default is to build COFF-only support. To get a set of tools that generate - ELF (they'll understand both COFF and ELF), you must configure with - target=i386-unknown-sco3.2v5elf. - -* m88k-motorola-sysv3* support added. - -Changes in 2.6: - -* Gas now directly supports macros, without requiring GASP. - -* Gas now has an MRI assembler compatibility mode. Use -M or --mri to select - MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the - ``.mri 0'' is seen; this can be convenient for inline assembler code. - -* Added --defsym SYM=VALUE option. - -* Added -mips4 support to MIPS assembler. - -* Added PIC support to Solaris and SPARC SunOS 4 assembler. - -Changes in 2.4: - -* Converted this directory to use an autoconf-generated configure script. - -* ARM support, from Richard Earnshaw. - -* Updated VMS support, from Pat Rankin, including considerably improved - debugging support. - -* Support for the control registers in the 68060. - -* Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to - provide for possible future gcc changes, for targets where gas provides some - features not available in the native assembler. If the native assembler is - used, it should become obvious pretty quickly what the problem is. - -* Usage message is available with "--help". - -* The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 - also, but didn't get into the NEWS file.) - -* Weak symbol support for a.out. - -* A bug in the listing code which could cause an infinite loop has been fixed. - Bugs in listings when generating a COFF object file have also been fixed. - -* Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by - Paul Kranenburg. - -* Improved Alpha support. Immediate constants can have a much larger range - now. Support for the 21164 has been contributed by Digital. - -* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. - -Changes in 2.3: - -* Mach i386 support, by David Mackenzie and Ken Raeburn. - -* RS/6000 and PowerPC support by Ian Taylor. - -* VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, - based on mail received from various people. The `-h#' option should work - again too. - -* HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work - with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special - version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve - this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu - in the "dist" directory. - -* Vax support in gas fixed for BSD, so it builds and seems to run a couple - simple tests okay. I haven't put it through extensive testing. (GNU make is - currently required for BSD 4.3 builds.) - -* Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is - based on code donated by CMU, which used an a.out-based format. I'm afraid - the alpha-a.out support is pretty badly mangled, and much of it removed; - making it work will require rewriting it as BFD support for the format anyways. - -* Irix 5 support. - -* The test suites have been fixed up a bit, so that they should work with a - couple different versions of expect and dejagnu. - -* Symbols' values are now handled internally as expressions, permitting more - flexibility in evaluating them in some cases. Some details of relocation - handling have also changed, and simple constant pool management has been - added, to make the Alpha port easier. - -* New option "--statistics" for printing out program run times. This is - intended to be used with the gcc "-Q" option, which prints out times spent in - various phases of compilation. (You should be able to get all of them - printed out with "gcc -Q -Wa,--statistics", I think.) - -Changes in 2.2: - -* RS/6000 AIX and MIPS SGI Irix 5 support has been added. - -* Configurations that are still in development (and therefore are convenient to - have listed in configure.in) still get rejected without a minor change to - gas/Makefile.in, so people not doing development work shouldn't get the - impression that support for such configurations is actually believed to be - reliable. - -* The program name (usually "as") is printed when a fatal error message is - displayed. This should prevent some confusion about the source of occasional - messages about "internal errors". - -* ELF support is falling into place. Support for the 386 should be working. - Support for SPARC Solaris is in. HPPA support from Utah is being integrated. - -* Symbol values are maintained as expressions instead of being immediately - boiled down to add-symbol, sub-symbol, and constant. This permits slightly - more complex calculations involving symbols whose values are not alreadey - known. - -* DBX-style debugging info ("stabs") is now supported for COFF formats. - If any stabs directives are seen in the source, GAS will create two new - sections: a ".stab" and a ".stabstr" section. The format of the .stab - section is nearly identical to the a.out symbol format, and .stabstr is - its string table. For this to be useful, you must have configured GCC - to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB - that can use the stab sections (4.11 or later). - -* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS - support is in progress. - -Changes in 2.1: - -* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been - incorporated, but not well tested yet. - -* Altered the opcode table split for m68k; it should require less VM to compile - with gcc now. - -* Some minor adjustments to add (Convergent Technologies') Miniframe support, - suggested by Ronald Cole. - -* HPPA support (running OSF only, not HPUX) has been contributed by Utah. This - includes improved ELF support, which I've started adapting for SPARC Solaris - 2.x. Integration isn't completely, so it probably won't work. - -* HP9000/300 support, donated by HP, has been merged in. - -* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. - -* Better error messages for unsupported configurations (e.g., hppa-hpux). - -* Test suite framework is starting to become reasonable. - -Changes in 2.0: - -* Mostly bug fixes. - -* Some more merging of BFD and ELF code, but ELF still doesn't work. - -Changes in 1.94: - -* BFD merge is partly done. Adventurous souls may try giving configure the - "--with-bfd-assembler" option. Currently, ELF format requires it, a.out - format accepts it; SPARC CPU accepts it. It's the default only for OS "elf" - or "solaris". (ELF isn't really supported yet. It needs work. I've got - some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not - fully merged yet.) - -* The 68K opcode table has been split in half. It should now compile under gcc - without consuming ridiculous amounts of memory. - -* A couple data structures have been reduced in size. This should result in - saving a little bit of space at runtime. - -* Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF - code provided ROSE format support, which I haven't merged in yet. (I can - make it available, if anyone wants to try it out.) Ralph's code, for BSD - 4.4, supports a.out format. We don't have ECOFF support in just yet; it's - coming. - -* Support for the Hitachi H8/500 has been added. - -* VMS host and target support should be working now, thanks chiefly to Eric - Youngdale. - -Changes in 1.93.01: - -* For m68k, support for more processors has been added: 68040, CPU32, 68851. - -* For i386, .align is now power-of-two; was number-of-bytes. - -* For m68k, "%" is now accepted before register names. For COFF format, which - doesn't use underscore prefixes for C labels, it is required, so variable "a0" - can be distinguished from the register. - -* Last public release was 1.38. Lots of configuration changes since then, lots - of new CPUs and formats, lots of bugs fixed. - - -Local variables: -fill-column: 79 -End: |
