macOS universal dylibs #8

Closed PokeMMO closed 3 years ago

PokeMMO commented 4 years ago

macOS's dylib supports multiple archs in a singe universal dylib file. This enables usage of "upgraded" arch "slices" like x86_64h which includes haswell+ optimizations.

With macOS arm coming up, we should discuss moving dylib to a single universal dylib for simplicity, or doing the same arm split we do for other platforms.

The compiler options would probably look something like -arch arm64 -arch arm64e -arch x86_64 -arch x86_64h

LWJGL3 decided on split dylibs for major archs.
