Ian Romanick	995d993710	i965/vec4: Don't cmod propagate from CMP to ADD if the writemask isn't compatible ... Otherwise we can incorrectly cmod propagate in situations like add(8) g10<1>.xD g2<0>.xD -16D ... cmp.ge.f0(8) null<1>D g2<0>.xD 16D ... (+f0) sel(8) g21<1>.xyUD g14<4>.xyyyUD g18<4>.xyyyUD Sadly, this change hurts quite a few shaders. v2: Refactor writemask compatibility check into a separate function. Suggested by Caio. Ivy Bridge and Haswell had similar results.

Jason Ekstrand	700bebb958	i965: Move the back-end compiler to src/intel/compiler ... Mostly a dummy git mv with a couple of noticable parts: - With the earlier header cleanups, nothing in src/intel depends files from src/mesa/drivers/dri/i965/ - Both Autoconf and Android builds are addressed. Thanks to Mauro and Tapani for the fixups in the latter - brw_util.[ch] is not really compiler specific, so it's moved to i965. v2: - move brw_eu_defines.h instead of brw_defines.h - remove no-longer applicable includes - add missing vulkan/ prefix in the Android build (thanks Tapani) v3: - don't list brw_defines.h in src/intel/Makefile.sources (Jason) - rebase on top of the oa patches [Emil Velikov: commit message, various small fixes througout] Signed-off-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Jason Ekstrand <jason@jlekstrand.net>	2017-03-13 11:16:34 +00:00
