From 2f2ab9b5bcada1134d48f7a150463aa6f3d65a8b Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 15 Oct 2019 18:49:36 -0400 Subject: [PATCH] gl_shader_decompiler: Mark ASTDecompiler/ExprDecompiler parameters as const references where applicable These member functions don't actually modify the input parameter, so we can make this explicit with the use of const. --- .../renderer_opengl/gl_shader_decompiler.cpp | 42 +++++++++---------- 1 file changed, 21 insertions(+), 21 deletions(-) diff --git a/src/video_core/renderer_opengl/gl_shader_decompiler.cpp b/src/video_core/renderer_opengl/gl_shader_decompiler.cpp index 82228b55d..20dc7d3db 100644 --- a/src/video_core/renderer_opengl/gl_shader_decompiler.cpp +++ b/src/video_core/renderer_opengl/gl_shader_decompiler.cpp @@ -2281,7 +2281,7 @@ class ExprDecompiler { public: explicit ExprDecompiler(GLSLDecompiler& decomp) : decomp{decomp} {} - void operator()(VideoCommon::Shader::ExprAnd& expr) { + void operator()(const ExprAnd& expr) { inner += "( "; std::visit(*this, *expr.operand1); inner += " && "; @@ -2289,7 +2289,7 @@ public: inner += ')'; } - void operator()(VideoCommon::Shader::ExprOr& expr) { + void operator()(const ExprOr& expr) { inner += "( "; std::visit(*this, *expr.operand1); inner += " || "; @@ -2297,17 +2297,17 @@ public: inner += ')'; } - void operator()(VideoCommon::Shader::ExprNot& expr) { + void operator()(const ExprNot& expr) { inner += '!'; std::visit(*this, *expr.operand1); } - void operator()(VideoCommon::Shader::ExprPredicate& expr) { + void operator()(const ExprPredicate& expr) { const auto pred = static_cast(expr.predicate); inner += decomp.GetPredicate(pred); } - void operator()(VideoCommon::Shader::ExprCondCode& expr) { + void operator()(const ExprCondCode& expr) { const Node cc = decomp.ir.GetConditionCode(expr.cc); std::string target; @@ -2329,11 +2329,11 @@ public: inner += target; } - void operator()(VideoCommon::Shader::ExprVar& expr) { + void operator()(const ExprVar& expr) { inner += GetFlowVariable(expr.var_index); } - void operator()(VideoCommon::Shader::ExprBoolean& expr) { + void operator()(const ExprBoolean& expr) { inner += expr.value ?
