[Qemu-devel] [PATCH v2 0/7] tcg-ppc qemu_ldst improvements

[Richard Henderson]

I'm not 100% sure what was wrong with v1 -- possibly some silly typo
fixed during rebasing on top of Paolo's patches.  I did that since at
minimum his patches are necessary for AIX fixes.

I tested my usual alpha/arm/sparc/x86 test images, and also Paulo's
sieve32.flat, and they all work now.

Speaking of sieve32.flat, unlike most of my kernel images, that's a
very easy to measure benchmark.  So I gave it a little whirl and I
see a 3% improvement on top of Paulo's patch set on a power7 host.
Most of this appears to be in the last patch, improving the tlb load.

This patch set is relative to mainline, so it will trivially conflict
with any previously posted patches within include/exec/exec-all.h.
