Remove WordsEmitted statistic; there's already a non-backend-specific
jello statistic for this (just divide #-bytes-of-code-emitted by 4). Rewrite head-of-file comment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9098 91177308-0d34-0410-b5e6-96231b3b80d8

// SPARC-specific backend for emitting machine code to memory.

//

// This module also contains the code for lazily resolving the targets
|
||||
// of call instructions, including the callback used to redirect calls
|
||||
// to functions for which the code has not yet been generated into the
|
||||
// JIT compiler.

|

// This file #includes SparcV9CodeEmitter.inc, which contains the code
|
||||
// for getBinaryCodeForInstr(), a method that converts a MachineInstr
|
||||
// into the corresponding binary machine code word.
