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 --- .../Shader/Decoders/OpCodeTextureScalar.cs | 61 ++++++++++++++++++++++ 1 file changed, 61 insertions(+) create mode 100644 Ryujinx.Graphics/Shader/Decoders/OpCodeTextureScalar.cs (limited to 'Ryujinx.Graphics/Shader/Decoders/OpCodeTextureScalar.cs') diff --git a/Ryujinx.Graphics/Shader/Decoders/OpCodeTextureScalar.cs b/Ryujinx.Graphics/Shader/Decoders/OpCodeTextureScalar.cs new file mode 100644 index 00000000..4389f453 --- /dev/null +++ b/Ryujinx.Graphics/Shader/Decoders/OpCodeTextureScalar.cs @@ -0,0 +1,61 @@ +using Ryujinx.Graphics.Shader.Instructions; + +namespace Ryujinx.Graphics.Shader.Decoders +{ + class OpCodeTextureScalar : OpCode + { +#region "Component mask LUT" + private const int ____ = 0x0; + private const int R___ = 0x1; + private const int _G__ = 0x2; + private const int RG__ = 0x3; + private const int __B_ = 0x4; + private const int RGB_ = 0x7; + private const int ___A = 0x8; + private const int R__A = 0x9; + private const int _G_A = 0xa; + private const int RG_A = 0xb; + private const int __BA = 0xc; + private const int R_BA = 0xd; + private const int _GBA = 0xe; + private const int RGBA = 0xf; + + private static int[,] _maskLut = new int[,] + { + { R___, _G__, __B_, ___A, RG__, R__A, _G_A, __BA }, + { RGB_, RG_A, R_BA, _GBA, RGBA, ____, ____, ____ } + }; +#endregion + + public Register Rd0 { get; } + public Register Ra { get; } + public Register Rb { get; } + public Register Rd1 { get; } + + public int Immediate { get; } + + public int ComponentMask { get; } + + protected int RawType; + + public bool IsFp16 { get; } + + public OpCodeTextureScalar(InstEmitter emitter, ulong address, long opCode) : base(emitter, address, opCode) + { + Rd0 = new Register(opCode.Extract(0, 8), RegisterType.Gpr); + Ra = new Register(opCode.Extract(8, 8), RegisterType.Gpr); + Rb = new Register(opCode.Extract(20, 8), RegisterType.Gpr); + Rd1 = new Register(opCode.Extract(28, 8), RegisterType.Gpr); + + Immediate = opCode.Extract(36, 13); + + int compSel = opCode.Extract(50, 3); + + RawType = opCode.Extract(53, 4); + + IsFp16 = !opCode.Extract(59); + + ComponentMask = _maskLut[Rd1.IsRZ ? 0 : 1, compSel]; + } + } +} \ No newline at end of file -- cgit v1.2.3
