c++: __has_builtin gives the wrong answer [PR106759]
We've supported __is_nothrow_constructible since r11-4386, but
names_builtin_p didn't know about it, so it gave the wrong answer for
#if __has_builtin(__is_nothrow_constructible)
...
#endif
I've tested all C++-only built-ins and only two were missing.
PR c++/106759
gcc/cp/ChangeLog:
* cp-objcp-common.cc (names_builtin_p): Handle RID_IS_NOTHROW_ASSIGNABLE
and RID_IS_NOTHROW_CONSTRUCTIBLE.
gcc/testsuite/ChangeLog:
* g++.dg/ext/has-builtin-1.C: New test.
