From 837d49a84e24420dbc06924f4862a5f7dcf4cace Mon Sep 17 00:00:00 2001 From: Michal Krol Date: Mon, 2 Jun 2008 11:31:52 +0200 Subject: gallium: The SWZ opcode no longer aliases MOV. Also, when the extended swizzle token is used, the simple swizzle and negate are set to X,Y,Z,W and FALSE, respectively. --- src/gallium/include/pipe/p_shader_tokens.h | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'src/gallium/include') diff --git a/src/gallium/include/pipe/p_shader_tokens.h b/src/gallium/include/pipe/p_shader_tokens.h index 282d32910eb..84e5096418b 100644 --- a/src/gallium/include/pipe/p_shader_tokens.h +++ b/src/gallium/include/pipe/p_shader_tokens.h @@ -232,7 +232,7 @@ struct tgsi_immediate_float32 /* * GL_ARB_vertex_program */ -#define TGSI_OPCODE_SWZ TGSI_OPCODE_MOV +#define TGSI_OPCODE_SWZ 118 #define TGSI_OPCODE_XPD TGSI_OPCODE_CROSSPRODUCT /* @@ -388,7 +388,7 @@ struct tgsi_immediate_float32 #define TGSI_OPCODE_KIL 116 /* unpredicated kill */ #define TGSI_OPCODE_END 117 /* aka HALT */ -#define TGSI_OPCODE_LAST 118 +#define TGSI_OPCODE_LAST 119 #define TGSI_SAT_NONE 0 /* do not saturate */ #define TGSI_SAT_ZERO_ONE 1 /* clamp to [0,1] */ @@ -621,6 +621,10 @@ struct tgsi_src_register_ext * * NegateX, NegateY, NegateZ and NegateW negate individual components of the * source register. + * + * NOTE: To simplify matter, if this token is present, the corresponding Swizzle + * and Negate fields in tgsi_src_register should be set to X,Y,Z,W + * and FALSE, respectively. */ struct tgsi_src_register_ext_swz -- cgit v1.2.3
