[Bug middle-end/25399] Another bogus 'clobbered by longjmp' message

[pinskia at gcc dot gnu dot org]

------- 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.
