From 17306c60ad61f5096010d210f5d3f6d0b3a99dad Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 11 Oct 2010 13:56:29 -0700 Subject: [PATCH] i965: Don't compute-to-MRF in gen6 VS math. There was code to do this for pre-gen6 already, this just enables it for gen6 as well. --- src/mesa/drivers/dri/i965/brw_vs_emit.c | 22 +++++++++++++++------- 1 file changed, 15 insertions(+), 7 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_vs_emit.c b/src/mesa/drivers/dri/i965/brw_vs_emit.c index 8ac979d..e2bff13 100644 --- a/src/mesa/drivers/dri/i965/brw_vs_emit.c +++ b/src/mesa/drivers/dri/i965/brw_vs_emit.c @@ -593,11 +593,15 @@ static void emit_math1( struct brw_vs_compile *c, struct brw_compile *p = &c->func; struct intel_context *intel = &p->brw->intel; struct brw_reg tmp = dst; - GLboolean need_tmp = (intel->gen < 6 && - (dst.dw1.bits.writemask != 0xf || - dst.file != BRW_GENERAL_REGISTER_FILE)); + GLboolean need_tmp = GL_FALSE; - if (need_tmp) + if (dst.file != BRW_GENERAL_REGISTER_FILE) + need_tmp = GL_TRUE; + + if (intel->gen < 6 && dst.dw1.bits.writemask != 0xf) + need_tmp = GL_TRUE; + + if (need_tmp) tmp = get_tmp(c); brw_math(p, @@ -626,9 +630,13 @@ static void emit_math2( struct brw_vs_compile *c, struct brw_compile *p = &c->func; struct intel_context *intel = &p->brw->intel; struct brw_reg tmp = dst; - GLboolean need_tmp = (intel->gen < 6 && - (dst.dw1.bits.writemask != 0xf || - dst.file != BRW_GENERAL_REGISTER_FILE)); + GLboolean need_tmp = GL_FALSE; + + if (dst.file != BRW_GENERAL_REGISTER_FILE) + need_tmp = GL_TRUE; + + if (intel->gen < 6 && dst.dw1.bits.writemask != 0xf) + need_tmp = GL_TRUE; if (need_tmp) tmp = get_tmp(c); -- 2.7.4
