annotate gen/optimizer.cpp @ 979:523bf4f166bc
Fix some assembler issues:
The assembler was miscompiling "add" (specifically, the "add reg/mem, imm"
variations).
The change that caused this seems to have been made because without it, some
"add"s didn't compile at all.
This patch reverts the previous change, and makes sure assembler operands are
remapped correctly even though the input operands auto-generated due to
updating operations aren't explicitly used.

Fixed the optimizer thing, since llvm PR 2800 is already fixed, users need to upgrade LLVM to latest svn.
