Optimized RetroPie image for Pi 3 hardware?
-
The base Raspbian OS is compiled for the ARM6 instruction set so it can run on all Pi models.
I'm curious if anyone has tried to recompile an entire RetroPie image with the latest GCC (has some new ARM optimizations) with compile flags specifically for the Pi 3 hardware?
-march=armv8-a+crc -mfpu=neon-fp-armv8 -mtune=cortex-a53
Would there be a performance gain that might help with some MAME roms or emulators that are on the cusp of running on the Pi but have some performance issues (N64, DC, PSP, DS, PS1, etc)?
Could someone make an image from optimized builds, or perhaps host a repository to download optimized packages?
In theory one could start just be recompiling a few emulators and seeing if there is any benefit at all, and then perhaps then moving on to a full rebuild of the entire OS/image.

No measurable performance increase from my testing. If you build from source you will get rpi3 optimised binaries.
