//
// This functionality is implemented by the lib/Assembly/Writer 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 file also defines functions that allow it to output files that a program
// called VCG can read.
//
// This library uses the Analysis library to figure out offsets for
// variables in the method tables...
