[Mesa-dev] [PATCH 42/42] i965/blorp: switch eu-emitter to use FS IR and fs_generator
Topi Pohjolainen

Fri Dec 20 06:39:11 PST 2013
Unfortunately the unit tests need to be patched as well. This is
because the direct eu-emitter only patches jump counters for
if-else (see patch_IF_ELSE()) while the fs_generator patches the
endif as well (see brw_set_uip_jip()).
No regressions on IVB (piglit quick + unit tests).
