Subject: [Qemu-devel] [PATCH v2 0/4] tcg/optimize: fixes and improvements
Date: Mon, 9 Sep 2013 19:27:46 +0200

This patchset first fixes known-zero bits optimization so that it works
in more than a few cases, and does some further optimizations for 32-bit
ops and unsigned loads.

v1 -> v2:
- swapped patches 1 & 2
- Cc:ed qemu-stable for patch 1
- improved description of patch 2

Aurelien Jarno (4):
  tcg/optimize: fix known-zero bits for right shift ops
  tcg/optimize: fix known-zero bits optimization
  tcg/optimize: improve known-zero bits for 32-bit ops
  tcg/optimize: add known-zero bits compute for load ops
