=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> option is given then it will generate LLVM bitcode 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 bitcode 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 bitcode file. This bitcode file can then be
|
|
linked with other bitcode 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 bitcode library.
|
|
|
|
=item B<-emit-llvm>
|
|
|
|
Make the output be LLVM bitcode (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.
