700bebb958
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>
