From b3371ed09e6866e235141119f9eecc2bb962dc8d Mon Sep 17 00:00:00 2001 From: Fernando Sahmkow Date: Mon, 30 Dec 2019 13:54:53 -0400 Subject: Shader_IR: add the ability to amend code in the shader ir. This commit introduces a mechanism by which shader IR code can be amended and extended. This useful for track algorithms where certain information can derived from before the track such as indexes to array samplers. --- src/video_core/renderer_opengl/gl_shader_decompiler.cpp | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'src/video_core/renderer_opengl') diff --git a/src/video_core/renderer_opengl/gl_shader_decompiler.cpp b/src/video_core/renderer_opengl/gl_shader_decompiler.cpp index a311dbcfe..e1730821f 100644 --- a/src/video_core/renderer_opengl/gl_shader_decompiler.cpp +++ b/src/video_core/renderer_opengl/gl_shader_decompiler.cpp @@ -751,6 +751,11 @@ private: Expression Visit(const Node& node) { if (const auto operation = std::get_if(&*node)) { + auto amend_index = operation->GetAmendIndex(); + if (amend_index) { + const Node& amend_node = ir.GetAmendNode(*amend_index); + Visit(amend_node).CheckVoid(); + } const auto operation_index = static_cast(operation->GetCode()); if (operation_index >= operation_decompilers.size()) { UNREACHABLE_MSG("Out of bounds operation: {}", operation_index); @@ -872,6 +877,11 @@ private: } if (const auto conditional = std::get_if(&*node)) { + auto amend_index = conditional->GetAmendIndex(); + if (amend_index) { + const Node& amend_node = ir.GetAmendNode(*amend_index); + Visit(amend_node).CheckVoid(); + } // It's invalid to call conditional on nested nodes, use an operation instead code.AddLine("if ({}) {{", Visit(conditional->GetCondition()).AsBool()); ++code.scope; @@ -884,6 +894,11 @@ private: } if (const auto comment = std::get_if(&*node)) { + auto amend_index = comment->GetAmendIndex(); + if (amend_index) { + const Node& amend_node = ir.GetAmendNode(*amend_index); + Visit(amend_node).CheckVoid(); + } code.AddLine("// " + comment->GetText()); return {}; } -- cgit v1.2.3
