=head1 NAME

|
|
|
||
|
|
llvm-as - LLVM assembler
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
llvm-as [options] [filename]
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<llvm-as> command invokes the LLVM assembler. It reads a file containing
|
||
|
|
human-readable LLVM assembly language, translates it to LLVM bytecode, 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.
|
||

=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 bytecode.
|
||
|
|
|
||
|
|
=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.
|
||
|
|
|
||
|
|
=item B<--stats>
|
||
|
|
|
||
|
|
Print statistics.
|
||
|
|
|
||
|
|
=item B<--time-passes>
|
||
|
|
|
||
|
|
Record the amount of time needed for each pass and print it to standard
|
||
|
|
error.
|
||
|
|
|
||
|
|
=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.
