flamingo:~/build/pa64/gcc$ cat a.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);
}

flamingo:~/build/pa64/gcc$ ./cc1 a.c -O0 -quiet
flamingo:~/build/pa64/gcc$ ./cc1 a.c -O -quiet
flamingo:~/build/pa64/gcc$ ./cc1 a.c -O2 -quiet

no problem here.  --target=hppa64-linux

I tried --target=hppa64-hpux but configure dies with

*** Configuration hppa64-hp-hpux not supported
Configure in /home/aldyh/build/pa64/gcc failed, exiting.

If you can get me a cross target triplet combo that'll build me a
cross ./cc1... I'll [try to] fix your problem ;-).
