|  |  | 
|  | 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. | 
|  |  |

|  |  | 
|  | =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. |
