[Qemu-devel] [PATCH 00/57] target-i386 eflags cleanup and bmi/adx extensions

[Richard Henderson]

This is a re-working of Paolo's eflags cleanup from October, which
I consider a pre-requisite to implementing the ADX extension.  I've
rearranged most of the patches in trivial ways, and some quite
significantly.

I've tested the result by running the FC17 installer in both i386
and x86_64 mode, and the bmi/adx extensions with small user-land
test cases.

The patch series is at

  git://github.com/rth7680/qemu.git eflags3

Please review.
