Author: Eric Anholt <e...@anholt.net> Date: Tue Mar 15 18:58:43 2016 -0700 vc4: Don't make a temporary for setting flags. The register allocator doesn't really do anything about the temp, so it doesn't seem like it should matter. However, the scheduler would think that a new def is being created. This doesn't change anything yet, but it avoids a bunch of regressions in the next commit. --- src/gallium/drivers/vc4/vc4_qir.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/gallium/drivers/vc4/vc4_qir.c b/src/gallium/drivers/vc4/vc4_qir.c index fd1192f..125a952 100644 --- a/src/gallium/drivers/vc4/vc4_qir.c +++ b/src/gallium/drivers/vc4/vc4_qir.c @@ -495,7 +495,8 @@ qir_SF(struct vc4_compile *c, struct qreg src) !c->defs[src.index] || last_inst != c->defs[src.index] || qir_is_multi_instruction(last_inst)) { - src = qir_MOV(c, src); + struct qreg null = { QFILE_NULL, 0 }; + last_inst = qir_MOV_dest(c, null, src); last_inst = (struct qinst *)c->instructions.prev; } last_inst->sf = true; _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-commit
