+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBclang\fR is a C, \*(C+, and Objective-C compiler which encompasses preprocessing,
+parsing, optimization, code generation, assembly, and linking.  Depending on
+which high-level mode setting is passed, Clang will stop before doing a full
+link.  While Clang is highly integrated, it is important to understand the
+stages of compilation, to understand how to invoke it.  These stages are:
+.IP "\fBDriver\fR" 4
+.IX Item "Driver"
+The \fBclang\fR executable is actually a small driver which controls the overall
+execution of other tools such as the compiler, assembler and linker.  Typically
+you do not need to interact with the driver, but you transparently use it to run
+the other tools.
+.IP "\fBPreprocessing\fR" 4
+.IX Item "Preprocessing"
+This stage handles tokenization of the input source file, macro expansion,
+#include expansion and handling of other preprocessor directives.  The output of
+this stage is typically called a \*(L".i\*(R" (for C), \*(L".ii\*(R" (for \*(C+), \*(L".mi\*(R" (for 
+Objective-C) , or \*(L".mii\*(R" (for Objective\-\*(C+) file.
+.IP "\fBParsing and Semantic Analysis\fR" 4
+.IX Item "Parsing and Semantic Analysis"
+This stage parses the input file, translating preprocessor tokens into a parse
+tree.  Once in the form of a parser tree, it applies semantic analysis to compute
+types for expressions as well and determine whether the code is well formed. This
+stage is responsible for generating most of the compiler warnings as well as
+parse errors.  The output of this stage is an \*(L"Abstract Syntax Tree\*(R" (\s-1AST\s0).
+.IP "\fBCode Generation and Optimization\fR" 4
+.IX Item "Code Generation and Optimization"
+This stage translates an \s-1AST\s0 into low-level intermediate code (known as \*(L"\s-1LLVM\s0
+\&\s-1IR\s0\*(R") and ultimately to machine code.  This phase is responsible for optimizing
+the generated code and handling target-specfic code generation.  The output of
+this stage is typically called a \*(L".s\*(R" file or \*(L"assembly\*(R" file.
+.Sp
+Clang also supports the use of an integrated assembler, in which the code
+generator produces object files directly. This avoids the overhead of generating
+the \*(L".s\*(R" file and of calling the target assembler.
+.IP "\fBAssembler\fR" 4
+.IX Item "Assembler"
+This stage runs the target assembler to translate the output of the compiler
+into a target object file.  The output of this stage is typically called a \*(L".o\*(R"
+file or \*(L"object\*(R" file.
+.IP "\fBLinker\fR" 4
+.IX Item "Linker"
+This stage runs the target linker to merge multiple object files into an
+executable or dynamic library.  The output of this stage is typically called an
+\&\*(L"a.out\*(R", \*(L".dylib\*(R" or \*(L".so\*(R" file.
+.PP
+The Clang compiler supports a large number of options to control each of these
+stages.  In addition to compilation of code, Clang also supports other tools:
+.PP
+\&\fBClang Static Analyzer\fR
+.PP
+The Clang Static Analyzer is a tool that scans source code to try to find bugs
+though code analysis.  This tool uses many parts of Clang and is built into the
+same driver.

+.IX Item "-fobjc-abi-version=version"
+Select the Objective-C \s-1ABI\s0 version to use. Available versions are 1 (legacy
+\&\*(L"fragile\*(R" \s-1ABI\s0), 2 (non-fragile \s-1ABI\s0 1), and 3 (non-fragile \s-1ABI\s0 2).
+.IP "\fB\-fobjc\-nonfragile\-abi\-version\fR=\fIversion\fR" 4
+.IX Item "-fobjc-nonfragile-abi-version=version"
+Select the Objective-C non-fragile \s-1ABI\s0 version to use by default. This will only
+be used as the Objective-C \s-1ABI\s0 when the non-fragile \s-1ABI\s0 is enabled (either via
+\&\-fobjc\-nonfragile\-abi, or because it is the platform default).
+.IP "\fB\-fobjc\-nonfragile\-abi\fR" 4
+.IX Item "-fobjc-nonfragile-abi"
+Enable use of the Objective-C non-fragile \s-1ABI\s0. On platforms for which this is
+the default \s-1ABI\s0, it can be disabled with \fB\-fno\-objc\-nonfragile\-abi\fR.
+.SS "Target Selection Options"
+.IX Subsection "Target Selection Options"
+Clang fully supports cross compilation as an inherent part of its design.
+Depending on how your version of Clang is configured, it may have support for
+a number of cross compilers, or may only support a native target.
+.IP "\fB\-arch\fR \fIarchitecture\fR" 4
+.IX Item "-arch architecture"
+Specify the architecture to build for.
+.IP "\fB\-mmacosx\-version\-min\fR=\fIversion\fR" 4

+When building for iPhone \s-1OS\s0, specify the minimum version supported by your
+application.
+.IP "\fB\-march\fR=\fIcpu\fR" 4
+.IX Item "-march=cpu"
+Specify that Clang should generate code for a specific processor family member
+and later.  For example, if you specify \-march=i486, the compiler is allowed to
+generate instructions that are valid on i486 and later processors, but which
+may not exist on earlier ones.
+.SS "Code Generation Options"
+.IX Subsection "Code Generation Options"
+.IP "\fB\-O0\fR \fB\-O1\fR \fB\-O2\fR \fB\-Os\fR \fB\-O3\fR \fB\-O4\fR" 4
+.IX Item "-O0 -O1 -O2 -Os -O3 -O4"
+Specify which optimization level to use.  \fB\-O0\fR means \*(L"no optimization\*(R": this
+level compiles the fastest and generates the most debuggable code.  \fB\-O2\fR is a
+moderate level of optimization which enables most optimizations.  \fB\-Os\fR is like
+\&\fB\-O2\fR with extra optimizations to reduce code size.  \fB\-O3\fR is like \fB\-O2\fR,
+except that it enables optimizations that take longer to perform or that may
+generate larger code (in an attempt to make the program run faster).  On
+supported platforms, \fB\-O4\fR enables link-time optimization; object files are
+stored in the \s-1LLVM\s0 bitcode file format and whole program optimization is done at
+link time. \fB\-O1\fR is somewhere between \fB\-O0\fR and \fB\-O2\fR.
+.IP "\fB\-g\fR" 4
+.IX Item "-g"
+Generate debug information.  Note that Clang debug information works best at
+\&\fB\-O0\fR.  At higher optimization levels, only line number information is
+currently available.
+.IP "\fB\-fexceptions\fR" 4
+.IX Item "-fexceptions"
+Enable generation of unwind information, this allows exceptions to be thrown
+through Clang compiled stack frames.  This is on by default in x86\-64.
+.IP "\fB\-ftrapv\fR" 4
+.IX Item "-ftrapv"
+Generate code to catch integer overflow errors.  Signed integer overflow is
+undefined in C, with this flag, extra code is generated to detect this and abort
+when it happens.
+.IP "\fB\-fvisibility\fR" 4
+.IX Item "-fvisibility"
+This flag sets the default visibility level.
+.IP "\fB\-fcommon\fR" 4
+.IX Item "-fcommon"
+This flag specifies that variables without initializers get common linkage.  It
+can be disabled with \fB\-fno\-common\fR.
+.IP "\fB\-flto\fR \fB\-emit\-llvm\fR" 4
+.IX Item "-flto -emit-llvm"
+Generate output files in \s-1LLVM\s0 formats, suitable for link time optimization. When
+used with \fB\-S\fR this generates \s-1LLVM\s0 intermediate language assembly files,
+otherwise this generates \s-1LLVM\s0 bitcode format object files (which may be passed
+to the linker depending on the stage selection options).
