Author: Brian Paul <[email protected]> Date: Wed Apr 8 19:35:24 2009 -0600 i965: set BRW_MASK_DISABLE flag in "send" instruction in brw_dp_READ_4() This fixes the random results that were seen when fetching a constant inside an IF/ELSE clause. Disabling the execution mask ensures that all the components of the register are written. --- src/mesa/drivers/dri/i965/brw_eu_emit.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_eu_emit.c b/src/mesa/drivers/dri/i965/brw_eu_emit.c index 21ce836..220c3af 100644 --- a/src/mesa/drivers/dri/i965/brw_eu_emit.c +++ b/src/mesa/drivers/dri/i965/brw_eu_emit.c @@ -978,9 +978,10 @@ void brw_dp_READ_4( struct brw_compile *p, { struct brw_instruction *insn = next_insn(p, BRW_OPCODE_SEND); - insn->header.predicate_control = 0; /* XXX */ + insn->header.predicate_control = BRW_PREDICATE_NONE; insn->header.compression_control = BRW_COMPRESSION_NONE; insn->header.destreg__conditonalmod = msg_reg_nr; + insn->header.mask_control = BRW_MASK_DISABLE; /* cast dest to a uword[8] vector */ dest = retype(vec8(dest), BRW_REGISTER_TYPE_UW); _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
