=head1 NAME
|
|
|
|
llvmg++ - LLVM C++ front-end
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
llvmg++ [options] filename
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<llvmg++> command is the LLVM C++ front end. It is a modified
|
|
version of g++ 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<llvmg++> 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<llvmg++>
|
|
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<llvmg++> has many
|
|
of g++'s features and accepts most of g++'s options. It handles a
|
|
number of g++'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<-Wl,>I<option>
|
|
|
|
Pass I<option> to the linker (usually gccld).
|
|
|
|
=back
|
|
|
|
=head1 EXIT STATUS
|
|
|
|
If B<llvmg++> succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non-zero value.
