From 65fc2ca82a38bc00ae4223124932af6771765041 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 19 Mar 2009 10:25:24 -0600 Subject: [PATCH] glsl: change GLSL #pragma initialization Initialize the shader's pragma settings before calling the compiler. Added pragma "Ignore" fields to allow overriding the #pragma directives found in shader source code. --- src/mesa/main/mtypes.h | 3 +++ src/mesa/shader/shader_api.c | 9 +++++++++ src/mesa/shader/slang/slang_compile.c | 4 +++- src/mesa/shader/slang/slang_preprocess.c | 23 ++++++++++------------- 4 files changed, 25 insertions(+), 14 deletions(-) diff --git a/src/mesa/main/mtypes.h b/src/mesa/main/mtypes.h index 3913828..5293009 100644 --- a/src/mesa/main/mtypes.h +++ b/src/mesa/main/mtypes.h @@ -1956,6 +1956,8 @@ struct gl_query_state /** Set by #pragma directives */ struct gl_sl_pragmas { + GLboolean IgnoreOptimize; /**< ignore #pragma optimize(on/off) ? */ + GLboolean IgnoreDebug; /**< ignore #pragma debug(on/off) ? */ GLboolean Optimize; /**< defaults on */ GLboolean Debug; /**< defaults off */ }; @@ -2026,6 +2028,7 @@ struct gl_shader_state GLboolean EmitComments; /**< Annotated instructions */ void *MemPool; GLbitfield Flags; /**< Mask of GLSL_x flags */ + struct gl_sl_pragmas DefaultPragmas; /**< Default #pragma settings */ }; diff --git a/src/mesa/shader/shader_api.c b/src/mesa/shader/shader_api.c index 9900acc..61289db 100644 --- a/src/mesa/shader/shader_api.c +++ b/src/mesa/shader/shader_api.c @@ -410,6 +410,12 @@ _mesa_init_shader_state(GLcontext * ctx) ctx->Shader.EmitCondCodes = GL_FALSE; ctx->Shader.EmitComments = GL_FALSE; ctx->Shader.Flags = get_shader_flags(); + + /* Default pragma settings */ + ctx->Shader.DefaultPragmas.IgnoreOptimize = GL_FALSE; + ctx->Shader.DefaultPragmas.IgnoreDebug = GL_FALSE; + ctx->Shader.DefaultPragmas.Optimize = GL_TRUE; + ctx->Shader.DefaultPragmas.Debug = GL_FALSE; } @@ -1444,6 +1450,9 @@ _mesa_compile_shader(GLcontext *ctx, GLuint shaderObj) if (!sh) return; + /* set default pragma state for shader */ + sh->Pragmas = ctx->Shader.DefaultPragmas; + /* this call will set the sh->CompileStatus field to indicate if * compilation was successful. */ diff --git a/src/mesa/shader/slang/slang_compile.c b/src/mesa/shader/slang/slang_compile.c index 3f46bfd..aa08022 100644 --- a/src/mesa/shader/slang/slang_compile.c +++ b/src/mesa/shader/slang/slang_compile.c @@ -2798,7 +2798,9 @@ _slang_compile(GLcontext *ctx, struct gl_shader *shader) shader->CompileStatus = success; if (success) { - _mesa_optimize_program(ctx, shader->Program); + if (shader->Pragmas.Optimize) { + _mesa_optimize_program(ctx, shader->Program); + } } if (ctx->Shader.Flags & GLSL_LOG) { diff --git a/src/mesa/shader/slang/slang_preprocess.c b/src/mesa/shader/slang/slang_preprocess.c index 89aaa3a..ff913ad 100644 --- a/src/mesa/shader/slang/slang_preprocess.c +++ b/src/mesa/shader/slang/slang_preprocess.c @@ -530,14 +530,6 @@ pp_ext_set(pp_ext *self, const char *name, GLboolean enable) } -static void -pp_pragmas_init(struct gl_sl_pragmas *pragmas) -{ - pragmas->Optimize = GL_TRUE; - pragmas->Debug = GL_FALSE; -} - - /** * Called in response to #pragma.
