Patch that fixes simplify_subreg_concatn

simplify_subreg_concatn passes VOIDmode of const_int elements of

(debug_insn 7 4 8 2 (var_location:V16QI vuchar (concatn:V16QI [
            (const_int 1 [0x1])
            (const_int 2 [0x2])
            (const_int 3 [0x3])
            (const_int 4 [0x4])
            (const_int 1 [0x1])
            (const_int 2 [0x2])
            (const_int 3 [0x3])
            (const_int 4 [0x4])
            (const_int 1 [0x1])
            (const_int 2 [0x2])
            (const_int 3 [0x3])
            (const_int 4 [0x4])
            (const_int 1 [0x1])
            (const_int 2 [0x2])
            (const_int 3 [0x3])
            (const_int 4 [0x4])
        ])) vector-shift2.c:14 -1
     (nil))

to simplify_gen_subreg as inner mode.

So, in case of VOIDmode, just determine the mode of the elements by using
GET_MODE_INNER of vector mode of concatn RTX.

Yes, I still would like to solve the problem.

I just uploaded the patch for the revision 163240 (2010-08-14). The bug is
still there. The problem happens when you compile the following code with "-On
-g".

#define vector(elcount, type)  \
__attribute__((vector_size((elcount)*sizeof(type)))) type

#define vidx(type, vec, idx) (*((type *) &(vec) + idx))
#define uchar unsigned char

#define ch14 1,2,3,4
#define ch1  1,1,1,1

int main (int argc, char *argv[]) {
    vector(16, uchar) vuchar  = { ch14, ch14, ch14, ch14};
    vector(16,  char) vchar0  = { ch1, ch1, ch1, ch1};
    vector(16, uchar) u1;

    u1 = vuchar << vchar0;

    if (vidx(char, u1, 0) != ((uchar)1  << (char)1))
        __builtin_abort ();

    vuchar <<= vchar0;
    return 0;
}

The error message is the same as in the original description.
Thanks for help.

Is this still a problem for you? I can try to help you here, but I need to know
what patch I should apply and to what revision, to reproduce the problem.
