=pod =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 bitcode 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> and B<-c> options are given then it will generate LLVM bitcode files instead. If B<-emit-llvm> and B<-S> are 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. See the gcc documentation for details. =head1 OPTIONS =over =item B<--help> Print a summary of command line options. =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 bitcode library. =item B<-emit-llvm> Make the output be LLVM bitcode (with B<-c>) or assembly (with B<-s>) instead of native object (or assembly). If B<-emit-llvm> is given without either B<-c> or B<-S> it has no effect. =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. =head1 SEE ALSO L<llvm-g++|llvmgxx> =head1 AUTHORS Maintained by the LLVM Team (L<http://llvm.org>). =cut
