From e43b250fc076aea9e4b5319fdf409e95b28ac8fc Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 17 Aug 2010 15:51:34 -0700 Subject: [PATCH] i915: Add support for reading output regs in the FS. Fixes glsl-unused-varying and many others, since we produce an output reg read any time gl_FragColor is written inside an if statement. --- src/mesa/drivers/dri/i915/i915_fragprog.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/src/mesa/drivers/dri/i915/i915_fragprog.c b/src/mesa/drivers/dri/i915/i915_fragprog.c index 2ba0d2c591e..3101bd17001 100644 --- a/src/mesa/drivers/dri/i915/i915_fragprog.c +++ b/src/mesa/drivers/dri/i915/i915_fragprog.c @@ -143,6 +143,20 @@ src_vector(struct i915_fragment_program *p, } break; + case PROGRAM_OUTPUT: + switch (source->Index) { + case FRAG_RESULT_COLOR: + src = UREG(REG_TYPE_OC, 0); + break; + case FRAG_RESULT_DEPTH: + src = UREG(REG_TYPE_OD, 0); + break; + default: + i915_program_error(p, "Bad source->Index: %d", source->Index); + return 0; + } + break; + /* Various paramters and env values.
