[Qemu-devel] [PATCH 0/8] tcg optimization improvements

[Richard Henderson]

The first 4 of these are ones that Aurelien posted some time ago,
and I reviewed, but never seemed to get committed.

The second 4 address optimization issues that I noticed with the
BMI instruction set extension, adding ANDC support to x86_64.

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

Richard Henderson (4):
  tcg/optimize: Handle known-zeros masks for ANDC
  tcg/optimize: Simply some logical ops to NOT
  tcg/optimize: Optmize ANDC X,Y,Y to MOV X,0
  tcg/optimize: Add more identity simplifications
