Re: [PATCH][ARM] Restrict store_minmaxsi

Hi all,

With this patch, we now only use the store_minmaxsi pattern when we're not
in a hot path.

We have found that this pattern can cause memory access bottlenecks in some
cases
(one benchmark was 45% slower when this pattern was enabled).

Tested arm-none-eabi on qemu.

Ok for trunk?

Thanks,
Kyrill
