2f6fdfb690b1e045d54f3198f3232dbe4c1eb4fc C++: don't offer bogus "._0" suggestions (PR c++/86329)
PR c++/86329 reports that the C++ frontend can offer bogus suggestions like:
#include <string>
int compare()
{
return __n1 - __n2;
}
suggested.cc: In function 'int compare()':
suggested.cc:5:10: error: '__n1' was not declared in this scope
return __n1 - __n2;
^~~~
suggested.cc:5:10: note: suggested alternative: '._61'
return __n1 - __n2;
^~~~
._61
suggested.cc:5:17: error: '__n2' was not declared in this scope
return __n1 - __n2;
^~~~
suggested.cc:5:17: note: suggested alternative: '._72'
return __n1 - __n2;
^~~~
._72
The dot-prefixed names are an implementation detail of how we implement
anonymous enums found in the header files, generated via
anon_aggrname_format in make_anon_name.
This patch uses anon_aggrname_p to filter them out when considering
which names to suggest.
