From 81d1a1133dad918cabc9f50948b6535b4a1e8893 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Tue, 25 Jan 2022 14:03:46 -0500 Subject: video_core/macro_interpreter: Move impl class to the cpp file Keeps the implementation hidden from the intended API and lessens the header dependencies on the interpreter's header. --- src/video_core/macro/macro_interpreter.cpp | 92 +++++++++++++++++++++++++++--- src/video_core/macro/macro_interpreter.h | 78 +------------------------ 2 files changed, 86 insertions(+), 84 deletions(-) diff --git a/src/video_core/macro/macro_interpreter.cpp b/src/video_core/macro/macro_interpreter.cpp index 8da26fd59..fba755448 100644 --- a/src/video_core/macro/macro_interpreter.cpp +++ b/src/video_core/macro/macro_interpreter.cpp @@ -2,6 +2,9 @@ // Licensed under GPLv2 or any later version // Refer to the license.txt file included. +#include +#include + #include "common/assert.h" #include "common/logging/log.h" #include "common/microprofile.h" @@ -11,16 +14,81 @@ MICROPROFILE_DEFINE(MacroInterp, "GPU", "Execute macro interpreter", MP_RGB(128, 128, 192)); namespace Tegra { -MacroInterpreter::MacroInterpreter(Engines::Maxwell3D& maxwell3d_) - : MacroEngine{maxwell3d_}, maxwell3d{maxwell3d_} {} +namespace { +class MacroInterpreterImpl final : public CachedMacro { +public: + explicit MacroInterpreterImpl(Engines::Maxwell3D& maxwell3d_, const std::vector& code_) + : maxwell3d{maxwell3d_}, code{code_} {} -std::unique_ptr MacroInterpreter::Compile(const std::vector& code) { - return std::make_unique(maxwell3d, code); -} + void Execute(const std::vector& params, u32 method) override; + +private: + /// Resets the execution engine state, zeroing registers, etc. + void Reset(); + + /** + * Executes a single macro instruction located at the current program counter.
