Hi all, I'd like to backport some patches from Tamar in GCC 9 to GCC 8 that implement the complex arithmetic intrinsics for Advanced SIMD. These should have been present in GCC 8 that gained support for Armv8.3-a.
There were 4 follow-up fixes that I've rolled into the one commit.
Bootstrapped and tested on aarch64-none-linux-gnu and arm-none-linux-gnueabihf
on the GCC 8 branch.
Pushing to the releases/gcc-8 branch.
Thanks,
Kyrill
