While compiling pcsx_rearmed I set the option to enable neon.
$this->bbcode_second_pass_code('', './configure --platform=libretro --enable-neon')
This produced countless errors. I did some research and found out that the issue has to do with how I'm setting the mfpu in the CFLAGS. I changed the mfpu to NEON and recompiled. I received no errors this time.
From what I understand, mfpu=vfpv3-d16 was used since it's the lowest common denominator among ARMv7 cpus. I'm wondering if i'm missing out on any performance enhancements due to the base system and installed packages being compiled without neon enabled. Are there any packages I should go back and specifically recompile?
A better formed question: Is there any way to query and find a list of packages that take advantage of neon?
Thanks
