devilismyfriend 01c4e3edf7 feat(relinker): --to-intel lowers SSE4a sites to same-length jumps into an appended stub section 
EXTRQ, INSERTQ, MOVNTSS and MOVNTSD are rewritten at relink time: same-length in-place forms
where they exist, otherwise a jmp rel32 into an appended executable section holding a
scratch-free SSE body and a jump back, so no code shifts and no RIP-relative or jump-table
operand needs adjusting. Decoder fixes for POPCNT and 0F BB (BTC), codegen and elfpatcher
tests, README and technical-debt notes. The runtime illegal-instruction trap stays as a
fallback.

About

Tool for automatic executables porting to Linux and Windows.

Includes a relinker that converts executable to the target system's native format and implementations of system prx libraries suitable for dynamic linking. No emulation or separate runtime process.

relinker --to-intel rewrites the Zen 2-only instructions a title may contain (EXTRQ, INSERTQ, MOVNTSS, MOVNTSD) at relink time, in place when an equal-length Intel encoding exists and otherwise through a jump to a generated stub section, so Intel hosts need no runtime emulation.

Releases will be published after the first full successful launch of at least one game.

Status

Execution reaches _start, stack unwinding and exception handling tables are built, reaches main. Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.

The shader recompiler successfully produces validated via Spirv-Tools SPIR-V.

The real game reaches the logo, main menu, and gameplay with audio.

Technical debt of the project, code style conventions

Build

The relinker uses only the C++20 standard library and should build with any conforming compiler.

libc.prx implementations contain compiler-specific code. Linux builds work with GCC; on Windows, MinGW-w64 GCC 15.2.0 (winlibs-gcc15, x86_64-ucrt-posix-seh) is currently required.

The project targets maximum compiler portability. Support for additional compilers will be addressed after the first successful game launch.
