    should compiling with -mcpu=cortex-a53 -mfpu=neon-vfpv4 have any noticeable effect ? i changed it in the cmakefile script of PPSSPP, compiled manually and verified with VERBOSE=1 that it was using it. But i could not tell any noticeable diffrence when using the build binary. I guess to libraries used like perhaps SDL etc would have to be compiled with those flags as well but even then i’m not sure if diffrences will be seen.

    i didn’t expect anything though was just playing around and thought that i might try it

    also i guess if i define -mcpu=cortex-a53 armv8 code is generated ?

    edit: on a side note yesterday i was playing with -fprofile-generate and -fprofileuse to generate gcda files to help with optimazation when compiling again but that did not produce any noticeable effects as well
