[Bug target/13780] New: ICE on simple altivec code compiled w/o -mabi=altivec flag

[qboosh at pld-linux dot org]

The following code triggers ICE in 3.3.2 (doesn't matter if PR target/11793 fix
is applied or not - I tried both versions, so it's different issue). I was told
that the same occurs on 3.4 branch and mainline.

This is already preprocessed and simplified code:

typedef __attribute__((vector_size(16))) signed int vector_s_t;

static vector_s_t my_vec_and (vector_s_t const A, vector_s_t const B)
{
return __builtin_altivec_vand(A, B);
}

When compiling with just -maltivec I get:

$ gcc -c alt.i -maltivec
alt.i: In function `my_vec_and':
alt.i:6: error: unrecognizable insn:
(insn 5 4 30 0 (nil) (set (reg:V4SI 119)
        (mem/u/f:V4SI (plus:SI (reg/f:SI 67 ap)
                (const_int 8 [0x8])) [0 B+0 S16 A128])) -1 (nil)
    (nil))
alt.i:6: internal compiler error: in extract_insn, at recog.c:2175
Please submit a full bug report,
with preprocessed source if appropriate.

But:

$ gcc -c alt.i -maltivec -mabi=altivec
$

I haven't found such information, but I suppose that altivec ABI may be needed
for this code (for function to return a vector?) - so it probably fall under
"ice-on-invalid-code" - but please check.

This is ice-on-valid.

It is the same bug as altivec-5.c, for which there already is a PR.
