This test now also fails with 4.5 branch on powerpc64. It's a recent
regression, introduced somewhere between 20100701 and 20100708.
The -fdump-tree-vect-details file shows:
> fgrep vectorized vect-109.c.110t.vect
vect-109.c:33: note: not vectorized: control flow in loop.
vect-109.c:26: note: === vect_mark_stmts_to_be_vectorized ===
vect-109.c:26: note: not vectorized: unsupported unaligned store.
vect-109.c:20: note: vectorized 0 loops in function.
vect-109.c:55: note: not vectorized: control flow in loop.
vect-109.c:48: note: === vect_mark_stmts_to_be_vectorized ===
vect-109.c:48: note: not vectorized: unsupported unaligned store.
vect-109.c:42: note: vectorized 0 loops in function.
so it's not the common problem with too many vectorized loops.
I'll try reverting the PR44284 backport.
