Hi All,
The slp vectorization test currently fails on AArch32 and AArch64
due to it not taking into account that we do have 128 bit vectors in
NEON. This means that two of the loops get vectorized instead of just 1.
So update the conditions to include a check for neon.
Regtested on aarch64-none-elf.
Ok for trunk?
Thanks,
Tamar.
