NAME
llvm-gcc - LLVM C front-end
SYNOPSIS
llvm-gcc [options] filename
DESCRIPTION
The llvm-gcc command is the LLVM C front end. It is a modified version
of gcc that compiles C/ObjC programs into native objects, LLVM bitcode
or LLVM assembly language, depending upon the options.
By default, llvm-gcc compiles to native objects just like GCC does. If
the -emit-llvm and -c options are given then it will generate LLVM
bitcode files instead. If -emit-llvm and -S are given, then it will
generate LLVM assembly.
Being derived from the GNU Compiler Collection, llvm-gcc has many of
gcc's features and accepts most of gcc's options. It handles a number
of gcc's extensions to the C programming language. See the gcc
documentation for details.
OPTIONS
--help
Print a summary of command line options.
-o filename
Specify the output file to be filename.
-I directory
Add a directory to the header file search path. This option can be
repeated.
-L directory
Add directory to the library search path. This option can be
repeated.
-lname
Link in the library libname.[bc | a | so]. This library should be
a bitcode library.
-emit-llvm
Make the output be LLVM bitcode (with -c) or assembly (with -s)
instead of native object (or assembly). If -emit-llvm is given
without either -c or -S it has no effect.
EXIT STATUS
If llvm-gcc succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
