From c86b0766681f986951e53ea852858eb8d6ce9e32 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 9 Jul 2009 07:58:50 -0600 Subject: glsl: do const parameter optimization for array element actual parameters When a function parameter is const-qualified we can avoid making a copy of the actual parameter (we basically do a search/replace when inlining). This is now done for array element params too, resulting in better code (fewer MOV instructions). We should allow some other types of function arguments here but let's be conservative for the moment. --- src/mesa/shader/slang/slang_codegen.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src') diff --git a/src/mesa/shader/slang/slang_codegen.c b/src/mesa/shader/slang/slang_codegen.c index 24e9952386..2b7e781f98 100644 --- a/src/mesa/shader/slang/slang_codegen.c +++ b/src/mesa/shader/slang/slang_codegen.c @@ -1417,8 +1417,9 @@ slang_inline_function_call(slang_assemble_ctx * A, slang_function *fun, } else if (p->type.qualifier == SLANG_QUAL_CONST) { /* a constant input param */ - if (args[i].type == SLANG_OPER_IDENTIFIER || - args[i].type == SLANG_OPER_LITERAL_FLOAT) { + if (args[i].type == SLANG_OPER_IDENTIFIER || + args[i].type == SLANG_OPER_LITERAL_FLOAT || + args[i].type == SLANG_OPER_SUBSCRIPT) { /* replace all occurances of this parameter variable with the * actual argument variable or a literal. */ -- cgit v1.2.3
