FEX-2406 released

A new version of the FEX-EMU, which allows the execution of x86 and x86-64 binaries on an AArch64 host, has been released. The latest FEX-2406 FEX release provides a number of optimizations and fixes. The new register allocator has been installed, which improves efficiency while eliminating poor design mistakes. The AFP extension and RPRES are now supported, allowing for increased scalar SSE performance. 32-bit OpenGL thunking has been implemented, which reduces CPU time spent in the video driver. Default TSO emulation options have been updated, allowing users to turn them off for free speed. Several problems have been resolved, including edge case behavior with the NOFOLLOW flag and behavior during optimization passes. ARM64EC improvements have been implemented, including integration with upstream WINE for ARM64EC support. The NVIDIA Orin CPU errata has been corrected, indicating a 9% discrepancy in clock speeds between the NVIDIA Orin and Snapdragon 8cx Gen 3 platforms. The release is expected to increase performance and allow programs to function at nearly native speeds.
