From: Ben Skeggs Date: Sat, 20 Jan 2007 22:48:33 +0000 (+1100) Subject: nouveau: rename pass0_arb to pass0. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4f800c5bacb9734d3030fe11144c8003ec4f169a;p=mesa.git nouveau: rename pass0_arb to pass0. I was expecting to have 2 frontends for the shader code (asm, glsl). With Brian's work on GLSL this is unnecessary :) --- diff --git a/src/mesa/drivers/dri/nouveau/Makefile b/src/mesa/drivers/dri/nouveau/Makefile index 7ffba27bac0..9718f3bf466 100644 --- a/src/mesa/drivers/dri/nouveau/Makefile +++ b/src/mesa/drivers/dri/nouveau/Makefile @@ -20,7 +20,7 @@ DRIVER_SOURCES = \ nouveau_span.c \ nouveau_state.c \ nouveau_shader.c \ - nouveau_shader_0_arb.c \ + nouveau_shader_0.c \ nouveau_shader_1.c \ nouveau_shader_2.c \ nouveau_tex.c \ diff --git a/src/mesa/drivers/dri/nouveau/nouveau_shader.c b/src/mesa/drivers/dri/nouveau/nouveau_shader.c index dc366b36c09..e4db1153625 100644 --- a/src/mesa/drivers/dri/nouveau/nouveau_shader.c +++ b/src/mesa/drivers/dri/nouveau/nouveau_shader.c @@ -111,7 +111,7 @@ nvsUpdateShader(GLcontext *ctx, nouveauShader *nvs) /* Translate to HW format now if necessary */ if (!nvs->translated) { /* Mesa ASM shader -> nouveauShader */ - if (!nouveau_shader_pass0_arb(ctx, nvs)) + if (!nouveau_shader_pass0(ctx, nvs)) return GL_FALSE;
