;; MEM[(unsigned char * <address-space-2> *)vectp_s.11_53] = { 0, 0 };
(insn 34 33 35 (set (reg:V2DI 125)
(const_vector:V2DI [
(const_int 0 [0])
(const_int 0 [0])
])) "t.c":3 -1
(nil))
(insn 35 34 0 (set (mem:V2DI (reg/f:DI 108 [ vectp_s.12 ]) [1 MEM[(unsigned
char * <address-space-2> *)vectp_s.11_53]+0 S16 A128])
(reg:V2DI 125)) "t.c":3 -1
(nil))
the MEM_EXPR again has wrong type, only the pointer arg has the address-space
qualifier.
The issue is we pun pointers to scalars in get_vectype_for_scalar_type_and_size
and that loses address-space info.
