[SPEC2006]### Compiler Error during Reading WHIRL file phase: ### OPCODE_make_op: no opcode available: 0 0 0

[zqb-all]

spec2k6 456.hmmer build fail. one of the errors can be reproduce by the following code:

double sre_random(void)
{
    static long  rnd1;
    static long  rnd2;
    static long  tbl[64];
    int i;
    for (i = 0; i < 64; i++) {
        tbl[i] = rnd1-rnd2;
        if (tbl[i] < 0)
            tbl[i] += 1;
    }
    return 0;
}

error:
