Author: Eric Anholt <e...@anholt.net> Date: Tue Jun 23 18:08:49 2015 -0700 vc4: Don't try to CSE color reads. It returns a new value for each sample in the TLB. We've already avoided trying to get the same index's color multiple times at the vc4_program.c level, so we're not losing anything by doing this. --- src/gallium/drivers/vc4/vc4_opt_cse.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/gallium/drivers/vc4/vc4_opt_cse.c b/src/gallium/drivers/vc4/vc4_opt_cse.c index 92c8260..51a5650 100644 --- a/src/gallium/drivers/vc4/vc4_opt_cse.c +++ b/src/gallium/drivers/vc4/vc4_opt_cse.c @@ -130,7 +130,8 @@ qir_opt_cse(struct vc4_compile *c) list_for_each_entry(struct qinst, inst, &c->instructions, link) { if (qir_has_side_effects(c, inst) || - qir_has_side_effect_reads(c, inst)) { + qir_has_side_effect_reads(c, inst) || + inst->op == QOP_TLB_COLOR_READ) { continue; } _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-commit
