With f16 rounding toward -infinity, v_fma_mixlo_f16 and v_fma_mixhi_f16 gave +0 for an exact cancellation such as 1.0 * 1.0 + -1.0, because the f64 sum is computed to nearest. RDNA2 gives -0 there, as IEEE 754 does for an exact zero sum rounded toward -infinity, measured on gfx1036 in #2631. An exact zero sum now gives -0 in that mode unless both the product and the addend are +0. A nonzero result that rounds to zero keeps its sign, so a tiny positive sum still gives +0.

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.

Status
* System libraries: percentage of the functions known to the project so far (declared in core/libs/prx), not of every PS5 system function. The total grows as more functions are declared.
Dreaming Sarah (2D platformer) runs at a stable 60 fps on a GTX 1050 Ti / i5-7500 3.4GHz.
Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.
The shader recompiler successfully produces SPIR-V (validated via Spirv-Tools when built with ANYPS5_ENABLE_SPIRV_TOOLS).
Compatibility
See the game compatibility list for tested games and known issues.
Input mapping
SDL-mapped game controllers are supported, including analog sticks and triggers. Keyboard and mouse controls can be configured with an anyps5-input.ini file. See input mapping for the supported devices and configuration format.
