Subject: [Qemu-devel] [PATCH 0/8] tcg optimization improvements
Date: Fri, 31 Jan 2014 08:46:55 -0600 [thread overview]
Message-ID: <1391179623-13626-1-git-send-email-rth@twiddle.net> (raw)
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.
r~
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
