//===----------------------------------------------------------------------===//
|
|
//
|
|
// This tool may be invoked in the following manner:
|
|
// llvm-abcd [options] - Read LLVM bytecode from stdin
|
|
// llvm-abcd [options] x.bc - Read LLVM bytecode from the x.bc file
|
|
//
|
|
// Options:
|
|
// --help - Output information about command line switches
|
|
// --details - Provide detailed analysis of individual functions
|
|
// --dump - Dump bytecode in readable format
|
|
//
|
|
// This tool provides analytical information about a bytecode file. It is
|
|
// intended as an aid to developers of bytecode reading and writing software. It
|
|
// produces on std::out a summary of the bytecode file that shows various
|
|
// statistics about the contents of the file. If the -details option is given
|
|
// then the output includes detailed information about each function in the
|
|
// bytecode file. The tool is also able to print a bytecode file in a straight
|
|
// forward text format // that shows the containment and relationships of the
|
|
// information in the bytecode file (-dump option).
