--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Found it:
/* In GIMPLE the type of the MEM_REF specifies the alignment. The
required alignment (power) is 4 bytes regardless of data type. */
tree align_ltype = build_aligned_type (lhs_type, 4);
That should be 4*8 instead of just 4.
There are 2 build_aligned_type in rs6000-builtins.cc which uses the wrong
alignment; thinking it was the alignment argument was bytes rather than bits.
Introduced by r9-2375-g3f7a77cd20d07c which means this is a regression.
