//===-- llvm/assembly/Writer.h - Printer for VM assembly files ---*- C++ -*--=//
|
||
|
|
//
|
||
|
|
// This functionality is implemented by the lib/AssemblyWriter library.
|
||
|
|
// This library is used to print VM assembly language files to an iostream. It
|
||
|
|
// can print VM code at a variety of granularities, ranging from a whole class
|
||
|
|
// down to an individual instruction. This makes it useful for debugging.
|
||
|
|
//
|
||
|
|
// This library uses the Analysis library to figure out offsets for
|
||
|
|
// variables in the method tables...
