[llvm-commits] CVS: llvm/lib/Target/Sparc/SparcV9CodeEmitter.cpp

[Brian Gaeke]

Changes in directory llvm/lib/Target/Sparc:

SparcV9CodeEmitter.cpp updated: 1.34 -> 1.35

---
Log message:

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.

-// FIXME: document
+// 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.
