=head1 DESCRIPTION
The B<llvm-bcanalyzer> command is a small utility for analyzing bytecode files.
The tool reads a bytecode file (such as generated with the B<llvm-as> tool) and
produces a statistical report on the contents of the byteocde file. The tool
can also dump a low level but human readable version of the bytecode file.

The tool reads a bitcode file (such as generated with the B<llvm-as> tool) and
produces a statistical report on the contents of the bitcode file. The tool
can also dump a low level but human readable version of the bitcode file.
This tool is probably not of much interest or utility except for those working
directly with the bytecode file format. Most LLVM users can just ignore
