5 llvm-gcc - LLVM C front-end
9 B<llvm-gcc> [I<options>] I<filename>
13 The B<llvm-gcc> command is the LLVM C front end. It is a modified
14 version of gcc that compiles C/ObjC programs into native objects, LLVM
15 bitcode or LLVM assembly language, depending upon the options.
17 By default, B<llvm-gcc> compiles to native objects just like GCC does. If the
18 B<-emit-llvm> option is given then it will generate LLVM bitcode files instead.
19 If B<-S> (assembly) is also given, then it will generate LLVM assembly.
21 Being derived from the GNU Compiler Collection, B<llvm-gcc> has many
22 of gcc's features and accepts most of gcc's options. It handles a
23 number of gcc's extensions to the C programming language.
31 Print a summary of command line options.
35 Do not generate an LLVM bitcode file. Rather, compile the source
36 file into an LLVM assembly language file.
40 Do not generate a linked executable. Rather, compile the source
41 file into an LLVM bitcode file. This bitcode file can then be
42 linked with other bitcode files later on to generate a full LLVM

73 If B<llvm-gcc> succeeds, it will exit with 0. Otherwise, if an error
74 occurs, it will exit with a non-zero value.
