| 8 | <H3>NAME</H3><TT>llvm-abcd</TT> |
| 9 | <H3>SYNOPSIS</H3><TT>llvm-abcd [options] [filename]</TT> |
| 10 | <H3>DESCRIPTION</H3>The <TT>llvm-abcd</TT> command is a small utility for analyzing |
| 11 | bytecode files. The <TT>abcd</TT> acronym stands for <u>a</u>nalysis of |
| 12 | <u>b</u>yte<u>c</u>ode <u>d</u>isplayer. The tool reads a bytecode file (such as |
| 13 | generated with the <TT>llvm-abcd</TT> tool) and produces statistical and low level |
| 14 | bytecode format dumps. This tool is probably not of much interest or utility except |
| 15 | for those working directly with the bytecode format. Most LLVM users can just ignore |
| 16 | this tool. |
| 17 | <P>If filename is omitted or is -, then <TT>llvm-abcd</TT> reads its input from |
| 18 | standard input. This is useful for combining <TT>llvm-abcd</TT> in a pipeline. |
| 19 | <P> |
| 20 | <H3>OPTIONS</H3> |
| 21 | <UL> |
| 22 | <LI>-nodetails <BR>Causes <TT>llvm-abcd</TT> to abbreviate its output by writing |
| 23 | out only a module level summary. The details for individual functions are not |
| 24 | displayed. |
| 25 | <P></P> |
| 26 | <LI>-dump <BR>Causes <TT>llvm-abcd</TT> to dump the bytecode in a human readable |
| 27 | format. This format is significantly different from LLVM assembly and provides |
| 28 | details about the encoding of the bytecode file. |
| 29 | <P></P> |
| 30 | <LI>-verify <BR>Causes <TT>llvm-abcd</TT> to verify the module produced by |
| 31 | by reading the bytecode. This ensures that the statistics generated are reliable. |
| 32 | <P></P> |
| 33 | <LI>-help <BR>Print a summary of command line options. |
| 34 | <P></P></LI></UL> |
| 35 | <H3>EXIT STATUS</H3>If <TT>llvm-abcd</TT> succeeds, it will exit with 0. |
| 36 | Otherwise, if an error occurs, it will exit with a non-zero value, usually 1. |
