Subject: [Bug middle-end/14505] New: __builtin_constant_p(__func__) is not true
Date: Tue, 09 Mar 2004 18:21:00 -0000	[thread overview]
Message-ID: <20040309182133.14505.alexr@spies.com> (raw)

The following code emits "non constant" but conceptually should emit "constant". The type of __func__ 
is "static const char *" so either fold_builtin_constant_p needs to be relaxed a bit or fname_decl should 
be building STRING_CST.

int main(int argc, char **argv)
{ 
  puts (__builtin_constant_p(__func__) ? "constant" : "non constant");
}
