gcc-11.0.0-alpha20200927 snapshot (g:e24817aa7a1c6d12039b486ab5ea9b5ee0a46cd4)
ICEs when compiling the following testcase w/ -O2 -fno-ipa-modref:

struct ie {
  int hk;
};

typedef int
gn (int, struct ie *);

int
de (int, struct ie *);

int
qc (int, struct ie *);

int bh;

int
uj (gn yz)
{
  struct ie *se = 0;

  if (se->hk == 1)
    return yz (bh, se);

  return 1;
}

int
n6 (void)
{
  (void) uj (qc);
  (void) uj (de);
}

% gcc-11.0.0 -O2 -fno-ipa-modref -c a7m1ghpt.c
during IPA pass: inline
a7m1ghpt.c: In function 'n6':
