Very good catch!  Here is C testcase.  I need to setup testing, then I
will try to debug the problem in combiner.

Honza

struct a
{
        int a;
        char b,c,d,e;
};
__attribute__ ((noinline))
__attribute__ ((regparm(1))) t(struct a a)
{
        if (a.a!=1 || a.b!=1 || a.c!=1)
                        abort();
}
main()
{
        struct a a;
        a.c=1;
        a.a=1;
        a.b=1;
        t(a);
        return 0;
}
