| <HR> |
| <H3>NAME</H3><TT>llvm-abcd</TT> |
| <H3>SYNOPSIS</H3><TT>llvm-abcd [options] [filename]</TT> |
| <H3>DESCRIPTION</H3>The <TT>llvm-abcd</TT> command is a small utility for analyzing |
| bytecode files. The <TT>abcd</TT> acronym stands for <u>a</u>nalysis of |
| <u>b</u>yte<u>c</u>ode <u>d</u>isplayer. The tool reads a bytecode file (such as |
| generated with the <TT>llvm-abcd</TT> 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. |
| <P>If filename is omitted or is -, then <TT>llvm-abcd</TT> reads its input from |
| standard input. This is useful for combining <TT>llvm-abcd</TT> in a pipeline. |
| <P> |
| <H3>OPTIONS</H3> |
| <UL> |
| <LI>-nodetails <BR>Causes <TT>llvm-abcd</TT> to abbreviate its output by writing |
| out only a module level summary. The details for individual functions are not |
| displayed. |
| <P></P> |
| <LI>-dump <BR>Causes <TT>llvm-abcd</TT> 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. |
| <P></P> |
| <LI>-verify <BR>Causes <TT>llvm-abcd</TT> to verify the module produced by |
| by reading the bytecode. This ensures that the statistics generated are reliable. |
| <P></P> |
| <LI>-help <BR>Print a summary of command line options. |
| <P></P></LI></UL> |
| <H3>EXIT STATUS</H3>If <TT>llvm-abcd</TT> succeeds, it will exit with 0. |
| Otherwise, if an error occurs, it will exit with a non-zero value, usually 1. |
