|
|
|
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.
