------- Comment #2 from pinskia at gcc dot gnu dot org 2005-12-13 22:42 -------
One more thing If I do:
struct ss { unsigned short a; unsigned short b; };
union uu { unsigned int all; struct ss parts; };
#include <setjmp.h>
extern void bar(union uu);
extern void baz();
void foo() {
for(;;)
{
union uu u;
jmp_buf env;
u.parts.a = f();
u.parts.b = u.parts.a;
bar(u);
if (setjmp(env)==0)
baz1();
else
baz();
}
}
I still get a warning but it actually will not be clobbered as it is spilled
anyways. Maybe we are warning for structs/unions as they are going to be
spilled anyways.
