From 48dca99feb394febc3af44e14f23fb12a9cc9204 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 10 Mar 2010 11:00:40 -0800 Subject: [PATCH] i965: Add support for the CMP opcode in the GLSL path. This would be triggered by use of sqrt() along with control flow. Fixes piglit-fs-sqrt-branch and a bug in Yo Frankie!. --- src/mesa/drivers/dri/i965/brw_wm.h | 6 ++++++ src/mesa/drivers/dri/i965/brw_wm_emit.c | 12 ++++++------ src/mesa/drivers/dri/i965/brw_wm_glsl.c | 3 +++ 3 files changed, 15 insertions(+), 6 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_wm.h b/src/mesa/drivers/dri/i965/brw_wm.h index 88d84ee82fe..47b764d24d1 100644 --- a/src/mesa/drivers/dri/i965/brw_wm.h +++ b/src/mesa/drivers/dri/i965/brw_wm.h @@ -328,6 +328,12 @@ void emit_cinterp(struct brw_compile *p, const struct brw_reg *dst, GLuint mask, const struct brw_reg *arg0); +void emit_cmp(struct brw_compile *p, + const struct brw_reg *dst, + GLuint mask, + const struct brw_reg *arg0, + const struct brw_reg *arg1, + const struct brw_reg *arg2); void emit_ddxy(struct brw_compile *p, const struct brw_reg *dst, GLuint mask, diff --git a/src/mesa/drivers/dri/i965/brw_wm_emit.c b/src/mesa/drivers/dri/i965/brw_wm_emit.c index 9315bca3156..c7d87b9d94c 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_emit.c +++ b/src/mesa/drivers/dri/i965/brw_wm_emit.c @@ -566,12 +566,12 @@ static void emit_sne( struct brw_compile *p, emit_sop(p, dst, mask, BRW_CONDITIONAL_NEQ, arg0, arg1); } -static void emit_cmp( struct brw_compile *p, - const struct brw_reg *dst, - GLuint mask, - const struct brw_reg *arg0, - const struct brw_reg *arg1, - const struct brw_reg *arg2 ) +void emit_cmp(struct brw_compile *p, + const struct brw_reg *dst, + GLuint mask, + const struct brw_reg *arg0, + const struct brw_reg *arg1, + const struct brw_reg *arg2) { GLuint i; diff --git a/src/mesa/drivers/dri/i965/brw_wm_glsl.c b/src/mesa/drivers/dri/i965/brw_wm_glsl.c index 14caf24e4b1..af249452b9b 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_glsl.c +++ b/src/mesa/drivers/dri/i965/brw_wm_glsl.c @@ -1869,6 +1869,9 @@ static void brw_wm_emit_glsl(struct brw_context *brw, struct brw_wm_compile *c) case OPCODE_LG2: emit_math1(c, BRW_MATH_FUNCTION_LOG, dst, dst_flags, args[0]); break; + case OPCODE_CMP: + emit_cmp(p, dst, dst_flags, args[0], args[1], args[2]); + break; case OPCODE_MIN: emit_min(p, dst, dst_flags, args[0], args[1]); break; -- 2.30.2
