reduced testcase

$ ./a.out && echo OK
OK
$ g++ pr45957.C -flto
$ ./a.out && echo OK
Tested revisions:
r165220 - fail
r165152 - OK
It seems __func__ evaluates to empty string in both cases (constructor and
destructor).

It seems __FUNCTION__ and __PRETTY_FUNCTION__ is broken too in constructors and destructors. g++.old-deja/g++.ext/pretty2.C actually gives nice output: $ g++ g++.old-deja/g++.ext/pretty2.C && ./a.out ctor __FUNCTION__ X __PRETTY_FUNCTION__ X::X() member fn __FUNCTION__ fn __PRETTY_FUNCTION__ void X::fn() conversion __FUNCTION__ operator int __PRETTY_FUNCTION__ X::operator int() dtor __FUNCTION__ ~X __PRETTY_FUNCTION__ X::~X() $ g++ g++.old-deja/g++.ext/pretty2.C -flto && ./a.out ctor __FUNCTION__ __PRETTY_FUNCTION__ member fn __FUNCTION__ fn __PRETTY_FUNCTION__ void X::fn() conversion __FUNCTION__ operator int __PRETTY_FUNCTION__ X::operator int() dtor __FUNCTION__ __PRETTY_FUNCTION__ ^ permalink raw reply [flat|nested] 6+ messages in thread

Surely an artifact of the C++ constructor/destructor cloning. We could simply remove if (TREE_CODE (decl) == VAR_DECL) { tree context = DECL_CONTEXT (decl); if (context) { enum tree_code code = TREE_CODE (context); if (code == FUNCTION_DECL && DECL_ABSTRACT (context)) { /* Do not clear the decl context here, that will promote all vars to global ones. */ DECL_INITIAL (decl) = NULL_TREE; } } } from free-lang-data. ^ permalink raw reply [flat|nested] 6+ messages in thread
