Subject: Don't hit an assertion failure when calculating the __PRETTY_FUNCTION__
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4ae711b5ef292378d5b88cede3d4b708174053e2;p=clang

Don't hit an assertion failure when calculating the __PRETTY_FUNCTION__
of a member function with parenthesized declarator.

Like this test case:

class Foo {
  const char *(baz)() {
    return __PRETTY_FUNCTION__;
  }
};
