From 6b23a2c125b9c48b5ebea92716004ef68698bb0f Mon Sep 17 00:00:00 2001 From: gdkchan Date: Wed, 17 Apr 2019 20:57:08 -0300 Subject: New shader translator implementation (#654) * Start implementing a new shader translator * Fix shift instructions and a typo * Small refactoring on StructuredProgram, move RemovePhis method to a separate class * Initial geometry shader support * Implement TLD4 * Fix -- There's no negation on FMUL32I * Add constant folding and algebraic simplification optimizations, nits * Some leftovers from constant folding * Avoid cast for constant assignments * Add a branch elimination pass, and misc small fixes * Remove redundant branches, add expression propagation and other improvements on the code * Small leftovers -- add missing break and continue, remove unused properties, other improvements * Add null check to handle empty block cases on block visitor * Add HADD2 and HMUL2 half float shader instructions * Optimize pack/unpack sequences, some fixes related to half float instructions * Add TXQ, TLD, TLDS and TLD4S shader texture instructions, and some support for bindless textures, some refactoring on codegen * Fix copy paste mistake that caused RZ to be ignored on the AST instruction * Add workaround for conditional exit, and fix half float instruction with constant buffer * Add missing 0.0 source for TLDS.LZ variants * Simplify the switch for TLDS.LZ * Texture instructions related fixes * Implement the HFMA instruction, and some misc. fixes * Enable constant folding on UnpackHalf2x16 instructions * Refactor HFMA to use OpCode* for opcode decoding rather than on the helper methods * Remove the old shader translator * Remove ShaderDeclInfo and other unused things * Add dual vertex shader support * Add ShaderConfig, used to pass shader type and maximum cbuffer size * Move and rename some instruction enums * Move texture instructions into a separate file * Move operand GetExpression and locals management to OperandManager * Optimize opcode decoding using a simple list and binary search * Add missing condition for do-while on goto elimination * Misc. fixes on texture instructions * Simplify TLDS switch * Address PR feedback, and a nit --- Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs | 17 ----------------- 1 file changed, 17 deletions(-) delete mode 100644 Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs (limited to 'Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs') diff --git a/Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs b/Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs deleted file mode 100644 index 6c16a145..00000000 --- a/Ryujinx.Graphics/Gal/Shader/ShaderIrOperPred.cs +++ /dev/null @@ -1,17 +0,0 @@ -namespace Ryujinx.Graphics.Gal.Shader -{ - class ShaderIrOperPred : ShaderIrNode - { - public const int UnusedIndex = 0x7; - public const int NeverExecute = 0xf; - - public bool IsConst => Index >= UnusedIndex; - - public int Index { get; set; } - - public ShaderIrOperPred(int index) - { - Index = index; - } - } -} \ No newline at end of file -- cgit v1.2.3
