[Qemu-devel] [PATCH 0/3] tcg-optimize with known-zero bits

[Richard Henderson <rth@twiddle.net>]

This patch set is extracted from Paolo's target-i386 eflags2
optimization branch:

  git://github.com/bonzini/qemu.git eflags2

I've cherry-picked 3 patches and rebased them vs master.  I've
made a few trivial changes to the patches:

  * Extracting reset_all_temps as a function,
  * Fixing a few type errors wrt target_ulong vs tcg_target_ulong.

While these were written in support of the other changes that
Paolo made wrt target-i386 eflags computation, they're not
dependent on them, and I think they should be considered for
inclusion regardless.

  optimize: only write to state when clearing optimizer data
  optimize: track nonzero bits of registers
  optimize: optimize using nonzero bits
