[Qemu-devel] [PATCH 00/10] tcg cleanup and optimization

[Richard Henderson]

Two unrelated changes here, but the first consists of only one patch and
I'm too lazy to do two patch sets.

The first change improves code for 64-bit guests on 32-bit hosts.  If we
can prove that one half of a 64-bit comparison is constant, we can simplify
to only comparing the other half.  This is most common with zero-extended
values such that 0:x == 0:y can be simplified to x == y.

The second change is a series of patches tidies the way helper.h is arranged.
This cleanup reduces the number of files that must be recompiled when the
old def-helper.h needed to be changed.  In the process, it moves some data
from arguments to tcg_callN into const static data within tcg.c.  This change
is a pre-requisite to being able to use libffi in the interpreter, but I think
the cleanups are nice enough to justify separate inclusion.
