LLVM: `llvm-abcd` tool

NAME

llvm-abcd

SYNOPSIS

llvm-abcd [options] [filename]

DESCRIPTION

The llvm-abcd command is a small utility for analyzing bytecode files. The abcd acronym stands for analysis of bytecode displayer. The tool reads a bytecode file (such as generated with the llvm-abcd 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 -, then llvm-abcd reads its input from standard input. This is useful for combining llvm-abcd in a pipeline.

OPTIONS

-nodetails
Causes llvm-abcd to abbreviate its output by writing out only a module level summary. The details for individual functions are not displayed.
-dump
Causes 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.
-verify
Causes llvm-abcd to verify the module produced by by reading the bytecode. This ensures that the statistics generated are reliable.
-help
Print a summary of command line options.

EXIT STATUS

If llvm-abcd succeeds, it will exit with 0. Otherwise, if an error occurs, it will exit with a non-zero value, usually 1.
