            Bug ID: 98722
           Summary: [11 Regression] ICE in lra_set_insn_recog_data, at
                    lra.c:1004 since
                    r11-6615-gcf2ac1c30af0fa783c8d72e527904dda5d8cc330
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---
              Host: x86_64-linux
            Target: s390x-linux-gnu

Since the revision I see the following ICE:

$ cat reint.cpp
struct B {
  virtual void Method();
};
typedef void (B::*fn_type_a)();

int main() {
  fn_type_a f(&B::Method);
  B b;
  (b.*f)();
}

$ ./xgcc -B. -Og -fno-tree-fre -fno-split-wide-types -c reint.cpp
during RTL pass: reload
reint.cpp: In function ‘int main()’:
reint.cpp:10:1: internal compiler error: in lra_set_insn_recog_data, at
