From ae4324032a48ee08a808354673f47536e76759d0 Mon Sep 17 00:00:00 2001 From: Andrey Sukharev Date: Thu, 19 Jan 2023 01:25:16 +0300 Subject: [PATCH] Optimize string memory usage. Use Spans and StringBuilders where possible (#3933) * Optimize string memory usage. Use ReadOnlySpan and StringBuilder where possible. * Fix copypaste error * Code generator review fixes * Use if statement instead of switch * Code style fixes Co-authored-by: TSRBerry <20988865+TSRBerry@users.noreply.github.com> * Another code style fix * Styling fix Co-authored-by: Mary-nyan * Styling fix Co-authored-by: gdkchan Co-authored-by: TSRBerry <20988865+TSRBerry@users.noreply.github.com> Co-authored-by: Mary-nyan Co-authored-by: gdkchan --- ARMeilleure/Decoders/OpCodeTable.cs | 12 +++--- ARMeilleure/Translation/PTC/Ptc.cs | 8 ++-- ARMeilleure/Translation/PTC/PtcProfiler.cs | 8 ++-- .../ViewModels/ControllerSettingsViewModel.cs | 2 +- Ryujinx.Common/Utilities/UInt128Utils.cs | 3 +- .../Glsl/Instructions/InstGenMemory.cs | 40 ++++++++++++------- .../Glsl/Instructions/InstGenPacking.cs | 3 +- Ryujinx.Graphics.Shader/Decoders/InstTable.cs | 11 ++--- Ryujinx.HLE/FileSystem/VirtualFileSystem.cs | 4 +- .../SoftwareKeyboard/InlineResponses.cs | 2 +- .../SoftwareKeyboardRendererBase.cs | 39 ++++++++++++------ .../Demangler/Ast/IntegerLiteral.cs | 3 +- .../HOS/Diagnostics/Demangler/Demangler.cs | 26 ++++++------ .../HOS/Services/Account/Acc/Types/UserId.cs | 5 ++- .../HOS/Services/Sockets/Nsd/IManager.cs | 3 +- Ryujinx.Horizon.Generators/CodeGenerator.cs | 15 ++++--- .../Kernel/SyscallGenerator.cs | 2 +- Ryujinx/Ui/Windows/AmiiboWindow.cs | 11 ++--- Ryujinx/Ui/Windows/ControllerWindow.cs | 2 +- 19 files changed, 118 insertions(+), 81 deletions(-) diff --git a/ARMeilleure/Decoders/OpCodeTable.cs b/ARMeilleure/Decoders/OpCodeTable.cs index 3f24986c..54abb141 100644 --- a/ARMeilleure/Decoders/OpCodeTable.cs +++ b/ARMeilleure/Decoders/OpCodeTable.cs @@ -1339,7 +1339,7 @@ namespace ARMeilleure.Decoders private static void SetT32(string encoding, InstName name, InstEmitter emitter, MakeOp makeOp) { - string reversedEncoding = encoding.Substring(16) + encoding.Substring(0, 16);
