<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.
