| |
| llvm-abcd - bytecode file low-level dumper |
| |
| =head1 SYNOPSIS |
| |
| llvm-abcd [options] [filename] |
| |
| =head1 DESCRIPTION |
| |
| The B<llvm-abcd> command is a small utility for analyzing bytecode files. The |
| B<abcd> acronym stands for B<a>nalysis of B<b>yteB<c>ode B<d>isplayer. The tool |
| reads a bytecode file (such as generated with the B<llvm-as> tool) and produces |
| statistical and low level bytecode format dumps. This tool is probably not of |
| much interest or utility except for those working directly with the bytecode |
| format. Most LLVM users can just ignore this tool. |
| |
| If filename is omitted or is I<->, then B<llvm-abcd> reads its input from |
| standard input. This is useful for combining B<llvm-abcd> in a pipeline. |
| |
| =head1 OPTIONS |
| |
| =over |
| |
| =item B<--nodetails> |
| |
| Causes B<llvm-abcd> to abbreviate its output by writing out only a module level |
| summary. The details for individual functions are not displayed. |
| |
| =item B<--dump> |
| |
| Causes B<llvm-abcd> to dump the bytecode in a human readable format. This format |
| is significantly different from LLVM assembly and provides details about the |
| encoding of the bytecode file. |
| |
| =item B<--verify> |
| |
| Causes B<llvm-abcd> to verify the module produced by by reading the bytecode. |
| This ensures that the statistics generated are reliable. |
| |
| =item B<--help> |
| |
| Print a summary of command line options. |
| |
| =back |
| |
| =head1 EXIT STATUS |
| |
| If B<llvm-abcd> succeeds, it will exit with zero exit status. Otherwise, if an |
| error occurs, it will exit with a non-zero exit status, usually 1. |
