=head1 NAME
llvm-as - LLVM assembler
=head1 SYNOPSIS
B<llvm-as> [I<options>] [I<filename>]
=head1 DESCRIPTION
B<llvm-as> is the LLVM assembler. It reads a file containing human-readable
LLVM assembly language, translates it to LLVM bitcode, and writes the result
into a file or to standard output.
If F<filename> is omitted or is C<->, then B<llvm-as> reads its input from
standard input.
If an output file is not specified with the B<-o> option, then
B<llvm-as> sends its output to a file or standard output by following
these rules:
=over
=item *
If the input is standard input, then the output is standard output.
=item *
If the input is a file that ends with C<.ll>, then the output file is of
the same name, except that the suffix is changed to C<.bc>.
=item *
If the input is a file that does not end with the C<.ll> suffix, then the
output file has the same name as the input file, except that the C<.bc>
suffix is appended.
=back
=head1 OPTIONS
=over
=item B<-f>
Force overwrite. Normally, B<llvm-as> will refuse to overwrite an
output file that already exists. With this option, B<llvm-as>
will overwrite the output file and replace it with new bitcode.
=item B<--help>
Print a summary of command line options.
=item B<-o> F<filename>
Specify the output file name. If F<filename> is C<->, then B<llvm-as>
sends its output to standard output.
=back
=head1 EXIT STATUS
If B<llvm-as> succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
