From 80b27ca2cd8cd2bb2937baa441c43a396887cc03 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sun, 24 Aug 2014 14:05:37 -0700 Subject: vc4: Switch to using native integers. There were troubles with bools without using native integers (st_glsl_to_tgsi seemed to think bool true was 1.0f sometimes, when as a uniform it's stored as ~0), and since I've got native integers other than divide, I might as well just support them. --- src/gallium/drivers/vc4/vc4_program.c | 171 +++++++++++++++++++++++++++++++++- 1 file changed, 167 insertions(+), 4 deletions(-) (limited to 'src/gallium/drivers/vc4/vc4_program.c') diff --git a/src/gallium/drivers/vc4/vc4_program.c b/src/gallium/drivers/vc4/vc4_program.c index aaa7eb346f3..82766ff1fc6 100644 --- a/src/gallium/drivers/vc4/vc4_program.c +++ b/src/gallium/drivers/vc4/vc4_program.c @@ -30,6 +30,7 @@ #include "util/u_memory.h" #include "tgsi/tgsi_parse.h" #include "tgsi/tgsi_dump.h" +#include "tgsi/tgsi_info.h" #include "vc4_context.h" #include "vc4_qpu.h" @@ -129,7 +130,8 @@ qir_uniform_f(struct tgsi_to_qir *trans, float f) } static struct qreg -get_src(struct tgsi_to_qir *trans, struct tgsi_src_register *src, int i) +get_src(struct tgsi_to_qir *trans, unsigned tgsi_op, + struct tgsi_src_register *src, int i) { struct qcompile *c = trans->c;
