Copilot Instructions

Project Guidelines

• When working in this PPSSPP workspace, the workspace root is C:\dev\ppsspp\Windows, so files outside the Windows directory (like GPU/Common/, Core/, etc.) must be accessed with the ".." prefix. For example, use "..\GPU\Common\DrawEngineCommon.cpp" instead of "GPU\Common\DrawEngineCommon.cpp" when calling file editing tools.

LSX documentation

• When writing code for LSX, the SIMD instruction set for Loongarch64, you can refer to:
  • http://ppsspp.org/unofficial/lsx/LSX_LASX_REFERENCE.md
  • http://ppsspp.org/unofficial/lsx/LSX_LASX_DETAILED.md
  • They might also be available at D:\Data\LSX.
  • These AI-friendly text files were generated from https://jia.je/unofficial-loongarch-intrinsics-guide/.
  • Note, verifying by compiling doesn't work, MSVC doesn't support LoongArch so the code is all ifdeff'ed out.
