--- Comment #12 from H.J. Lu <hjl.tools at gmail dot com> ---
ix86_find_max_used_stack_alignment fails to detect that

(insn 281 152 282 34 (set (mem/c:V16QI (reg/f:DI 2 cx [144]) [0 MEM
<char[1:32]> [(void *)_109]+0 S16 A128])
        (reg:V16QI 21 xmm1 [orig:156 MEM <char[1:32]> [(void *)_109] ] [156=
]))
"x.c":53:12 1824 {movv16qi_internal}
     (nil))

requires 16-byte aligned stack.=
