=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 takes C programs and compiles them into LLVM
bytecode or assembly language, depending upon the options.
Unless the B<-S> option is specified, B<llvm-gcc> will use the
L<gccas|gccas> program to perform some optimizations and create an
LLVM bytecode file. Unless the B<-c> option is specified, B<llvm-gcc>
will also use the L<gccld|gccld> program to perform further
optimizations and link the resulting bytecode file(s) with support
libraries to create an executable program.
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<-Wa,>I<option>
Pass I<option> to gccas
=item B<-Wl,>I<option>
Pass I<option> to gccld
=item B<-Wa,-disable-inlining -Wl,-disable-inlining>
Fully disable all inlining
=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.
