Hi,
This patch tries to implement division with multiplication by
reciprocal using vrecpe/vrecps
with -funsafe-math-optimizations and -freciprocal-math enabled.
Tested on arm-none-linux-gnueabihf using qemu.
OK for trunk ?
Thank you,

Hi Kyrill,
Hi,
This patch tries to implement division with multiplication by

with -funsafe-math-optimizations and -freciprocal-math enabled.
Tested on arm-none-linux-gnueabihf using qemu.
