[Qemu-devel] [PATCH 00/21] tcg-i386 cleanup and improvement

[Richard Henderson <rth@twiddle.net>]

Most of this patch series replaces the use of hard-coded constants
with symbolic definitions of the opcode space.  There are a few
changes to code generation scattered within, as I came across them.

After the review cycle on this sequence, I'll do the same for the
x86-64 port.  Although I do begin to wonder if we couldn't usefully
merge the two ports; the REX handling can't be that hard to have go
away under appropriate conditional compilation...
