I get a different error with today's compiler but that is because I am not compiling with --disable-
checking.
t.c:7: internal compiler error: in simplify_binary_operation, at simplify-rtx.c:2178
WTF:
(set (reg:V4SI 94)
(vec_concat:V4SF (mem:V2SF (reg:SI 64 [ ivtmp.66 ]) [0 S8 A8])
(vec_select:V2SF (reg:V4SI 94)
(parallel [
(const_int 2 [0x2])
(const_int 3 [0x3])
]))))
Which comes from the expansion of
;; *(vect_p.22 + (vector int *) D.1440 * 16B - 16B) = M*ivtmp.66{misalignment: 0}
