| =head1 NAME |
| |
| llvm-gcc - LLVM C front-end |
| |
| =head1 SYNOPSIS |
| |
| B<llvm-gcc> [I<options>] I<filename> |
| |
| =head1 DESCRIPTION |
| |
| The B<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 |
| bytecode or LLVM assembly language, depending upon the options. |
| |
| By default, B<llvm-gcc> compiles to native objects just like GCC does. If the |
| B<-emit-llvm> option is given then it will generate LLVM bytecode files instead. |
| If B<-S> (assembly) is also given, then it will generate LLVM assembly. |
| |
| Being derived from the GNU Compiler Collection, B<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. |
| |
| =head1 OPTIONS |
| |
| =over |
| |
| =item B<--help> |
| |
| Print a summary of command line options. |
| |
| =item B<-S> |
| |
| Do not generate an LLVM bytecode file. Rather, compile the source |
| file into an LLVM assembly language file. |
| |
| =item B<-c> |
| |
| Do not generate a linked executable. Rather, compile the source |
| file into an LLVM bytecode file. This bytecode file can then be |
| linked with other bytecode files later on to generate a full LLVM |
| executable. |
| |
| =item B<-o> I<filename> |
| |
| Specify the output file to be I<filename>. |
| |
| =item B<-I> I<directory> |
| |
| Add a directory to the header file search path. This option can be |
| repeated. |
| |
| =item B<-L> I<directory> |
| |
| Add I<directory> to the library search path. This option can be |
| repeated. |
| |
| =item B<-l>I<name> |
| |
| Link in the library libI<name>.[bc | a | so]. This library should |
| be a bytecode library. |
| |
| =item B<-emit-llvm> |
| |
| Make the output be LLVM bytecode (or assembly) instead of native object (or |
| assembly). |
| |
| =back |
| |
| =head1 EXIT STATUS |
| |
| If B<llvm-gcc> succeeds, it will exit with 0. Otherwise, if an error |
| occurs, it will exit with a non-zero value. |
