include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline
...
convenience method. Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
Take out LEAVE instructions.
32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
Add some simple code to Printer::runOnFunction to iterate over
MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
implicit defs "Void". Add more sign/zero extending "move" insns
(movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.

Fix two bugs:
...
* The globals vector was getting broken and unsorted, this caused vortex
to get badly pessimized
* Node offset handling was being handled really poorly, and in particular
we were not merging types with offsets right. This causes several graphs
to be non-merged.
