Hi guys!
I just saw this code inside "stella-libretro" core:
stella-libretro/Makefile at master · libretro/stella-libretro · GitHub
I don't have idea about the real improvement of this optimization on a Rpi3, but it looks nice.
Could you try to include something like this (a specific and oprimized Rpi3 build) when we compile LibreELEC from git (at least in the first stage, for beta testing)?
Thx!
Rpi3 like a specific platform

No, because currently the RPi3 uses the RPi2 build, this is because aarch64 kernel support isn't ready yet for the RPi3.

Has their been any movement on the 64bit side of things?

maybe popcornmix can shed some more light on it or can point you in the right direction regarding kernel sources.

Those compile flags are still for a 32-bit target.
Milhouse made a complete LE (may have been OE back then) build with "-mcpu=cortex-a53 -mfpu=neon-fp-armv8"
but was unable to measure any performance improvements.64-bit kernels do exist for Pi3, but so far have no GPU support (e.g. no hardware video decode) so are not useful for Kodi.
We are waiting for evidence of performance benefits of switching to 64-bit, but so far it's unclear.
Some benchmarks improve, some worsen with 64-bit.
