            Bug ID: 99108
           Summary: ICE in ix86_get_function_versions_dispatcher, at
                    config/i386/i386-features.c:2862
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal

          Reporter: gscfq@t-online.de
  Target Milestone: ---

Affects versions down to at least r5 (with -std=c++17) :


$ cat z1.cc
struct A {
  void foo(auto);
};
void A::foo(auto)
{
  int f(void) __attribute__((target("default")));
  int f(void) __attribute__((target("arch=atom")));
  int b = f();
}
void bar(void)
{
  A c;
  c.foo(7);
}


$ g++-11-20210214 -c z1.cc -std=c++2a
z1.cc: In instantiation of 'void A::foo(auto:2) [with auto:1 = int]':
z1.cc:13:10:   required from here
