Another way would probably be to ensure that f0 always appears as first operand
by adjusting the various patterns in ia64.md to only allow fr_reg_operand
in the 2nd operand slot of addsf3 (and maybe other patterns).

I disagree that it would be useful, it would encourage non-portable code, and

When porting my software from Win32 to Linux, i had to recompile it with gcc
under Mingw and also under Linux. There was a hurdle, because the loop shown
below in b) crashed after a while on both platforms. (I was happy to find the
location of the bug with gdb!) After rearranging the code like c)

struct Base1 {
virtual ~Base1() {}
};
struct Base2 {

struct Foo : Base1, Base2 {};
void f(Foo);

Base2* base = static_castBase2*(v);
Foo* foo = static_castFoo*(base);
f(*foo);
}
