| |
| llvm-upgrade - LLVM assembly upgrader |
| |
| =head1 SYNOPSIS |
| |
| B<llvm-upgrade> [I<options>] [I<filename>] |
| |
| =head1 DESCRIPTION |
| |
| B<llvm-upgrade> is the LLVM assembly upgrader. It reads a file containing |
| human-readable LLVM assembly language, and upgrades that assembly to the current |
| version of LLVM. If the input is in the form currently accepted by LLVM, then |
| no upgrades are performed. |
| |
| The expected usage of this tool is as a filter, like this: |
| |
| =over |
| |
| B<llvm-1.9/bin/llvm-dis < 1.9.bc | llvm-upgrade | llvm-2.0/bin/llvm-as -o 2.0.bc> |
| |
| =back |
| |
| If F<filename> is omitted or is C<->, then B<llvm-upgrade> reads its input from |
| standard input. |
| |
| If an output file is not specified with the B<-o> option, then |
| B<llvm-upgrade> sends its output to standard output. |
| |
| =head1 OPTIONS |
| |
| =over |
| |
| =item B<-f> |
| |
| Force overwrite. Normally, B<llvm-upgrade> will refuse to overwrite an |
| output file that already exists. With this option, B<llvm-upgrade> |
| will overwrite the output file. |
| |
| =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-upgrade> |
| sends its output to standard output. |
| |
| =back |
| |
| =head1 EXIT STATUS |
| |
| If B<llvm-upgrade> succeeds, it will exit with 0. Otherwise, if an error |
| occurs, it will exit with a non-zero value. |
