> Can you post x.c so I can try to debug this?

Sorry, x.c is just gcc.c-torture/compile/simd-1.c, I rename all my tests
to x.c when I work on them.

$ cat x.c
typedef int v2si __attribute__ ((mode(V2SI)));
typedef unsigned di __attribute__ ((mode(DI)));
void foo(unsigned long);
void bar() {
    v2si x = { 1, 2 };
    foo((di) x);
}

I don't know if building a cross ia64-hpux will work or not, but a pa64
version should at least build cc1.  These two platforms are behaving
slightly differently for me.  I can make IA64 work at all optimization
levels with the change that I included in my earlier mail
(http://gcc.gnu.org/ml/gcc/2002-07/msg01148.html) but PA64 will only
work at -O0 with that change, -O1/-O2/etc still fail with the
simplify_gen_subreg message.
