--- Comment #26 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, on my version of the testcase with r210843 -O3 -mcpu=power8 there are like
49
32 bit load in host endianness found at: _105 = MEM[(const unsigned char
*)load_src_25];
occurrences, so I've added a quick hack (should have used dbg counters
parhaps), and
with BSWAPCNT\x16 it works fine, with BSWAPCNT\x17 it fails.
In the *.optimized dump, I've noticed that this single load matters for
vectorization in md4_update function, with BSWAPCNT\x16 a chunk of code isn't
vectorized, with BSWAPCNT\x17 it is.

+cntx--;
align = get_object_alignment (src);
if (bswap && SLOW_UNALIGNED_ACCESS (TYPE_MODE (load_type), align))
return false;
So very well this might just trigger a latent bug in the vectorizer or powerpc
backend.
