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/ShaderDecodeHelper.cs | 78 ----------------------- 1 file changed, 78 deletions(-) delete mode 100644 Ryujinx.Graphics/Gal/Shader/ShaderDecodeHelper.cs (limited to 'Ryujinx.Graphics/Gal/Shader/ShaderDecodeHelper.cs') diff --git a/Ryujinx.Graphics/Gal/Shader/ShaderDecodeHelper.cs b/Ryujinx.Graphics/Gal/Shader/ShaderDecodeHelper.cs deleted file mode 100644 index 9a84e612..00000000 --- a/Ryujinx.Graphics/Gal/Shader/ShaderDecodeHelper.cs +++ /dev/null @@ -1,78 +0,0 @@ -namespace Ryujinx.Graphics.Gal.Shader -{ - static class ShaderDecodeHelper - { - private static readonly ShaderIrOperImmf ImmfZero = new ShaderIrOperImmf(0); - private static readonly ShaderIrOperImmf ImmfOne = new ShaderIrOperImmf(1); - - public static ShaderIrNode GetAluFabsFneg(ShaderIrNode node, bool abs, bool neg) - { - return GetAluFneg(GetAluFabs(node, abs), neg); - } - - public static ShaderIrNode GetAluFabs(ShaderIrNode node, bool abs) - { - return abs ? new ShaderIrOp(ShaderIrInst.Fabs, node) : node; - } - - public static ShaderIrNode GetAluFneg(ShaderIrNode node, bool neg) - { - return neg ? new ShaderIrOp(ShaderIrInst.Fneg, node) : node; - } - - public static ShaderIrNode GetAluFsat(ShaderIrNode node, bool sat) - { - return sat ? new ShaderIrOp(ShaderIrInst.Fclamp, node, ImmfZero, ImmfOne) : node; - } - - public static ShaderIrNode GetAluIabsIneg(ShaderIrNode node, bool abs, bool neg) - { - return GetAluIneg(GetAluIabs(node, abs), neg); - } - - public static ShaderIrNode GetAluIabs(ShaderIrNode node, bool abs) - { - return abs ? new ShaderIrOp(ShaderIrInst.Abs, node) : node; - } - - public static ShaderIrNode GetAluIneg(ShaderIrNode node, bool neg) - { - return neg ? new ShaderIrOp(ShaderIrInst.Neg, node) : node; - } - - public static ShaderIrNode GetAluNot(ShaderIrNode node, bool not) - { - return not ? new ShaderIrOp(ShaderIrInst.Not, node) : node; - } - - public static ShaderIrNode ExtendTo32(ShaderIrNode node, bool signed, int size) - { - int shift = 32 - size; - - ShaderIrInst rightShift = signed - ?
