|
||||
|
||||
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.
