Hi,
This is a rebased version of patch that adds a pattern to neon.md for
implementing division with multiplication by reciprocal using
vrecpe/vrecps with -funsafe-math-optimizations excluding -Os.
The newly added test-cases are not vectorized on armeb target with
-O2. I posted the analysis for tha

Hi Kyrill,
Thanks for the review
Hi Prathamesh,
This is probably not appropriate for -Os optimisation.
And for speed optimisation I imagine it can vary a lot on the target the code
is run.
Do you have any benchmark results for this patch?
Thanks,
Kyrill

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,
Prathamesh
