From 229db2b8ade33571e4cece1d838234895db220c2 Mon Sep 17 00:00:00 2001 From: Corbin Simpson Date: Wed, 10 Feb 2010 18:38:53 -0800 Subject: r300g: Work around "defect" in r300compiler. r300compiler doesn't handle half swizzles for vert shaders, which don't have them. So, for now, disable them. --- src/gallium/drivers/r300/r300_tgsi_to_rc.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/gallium/drivers/r300/r300_tgsi_to_rc.h') diff --git a/src/gallium/drivers/r300/r300_tgsi_to_rc.h b/src/gallium/drivers/r300/r300_tgsi_to_rc.h index 39b473c7bf..97641a954b 100644 --- a/src/gallium/drivers/r300/r300_tgsi_to_rc.h +++ b/src/gallium/drivers/r300/r300_tgsi_to_rc.h @@ -23,6 +23,8 @@ #ifndef R300_TGSI_TO_RC_H #define R300_TGSI_TO_RC_H +#include "pipe/p_compiler.h" + struct radeon_compiler; struct tgsi_full_declaration; @@ -41,6 +43,10 @@ struct tgsi_to_rc { int immediate_offset; struct swizzled_imms * imms_to_swizzle; unsigned imms_to_swizzle_count; + + /* Vertex shaders have no half swizzles, and no way to handle them, so + * until rc grows proper support, indicate if they're safe to use. */ + boolean use_half_swizzles; }; void r300_tgsi_to_rc(struct tgsi_to_rc * ttr, const struct tgsi_token * tokens); -- cgit v1.2.3
