--- Comment #15 from Surya Kumari Jangala <jskumari at gcc dot gnu.org> ---
This is another test which has unnecessary zero extension:

#include <stdbool.h>

bool glob1;
bool glob2;

bool foo (int a, bool d)
{
  bool c;
  if (a > 2)
    c =3D glob1 & glob2;
  else
    c =3D glob1 | glob2;
  return c^d;
}


I am not sure if this is handled by the patch at
https://gcc.gnu.org/pipermail/gcc-patches/2023-July/624751.html as the RTL =
for
this test has a different CFG shape than what is mentioned in the patch.=
