Patch from Eddie Elizondo. Reviewed as D37830 (https://reviews.llvm.org/D37830).
On MacOSX the following program:
struct S { virtual void f() = delete; };
int main() { new S; }
Fails with the following error:
Undefined symbols for architecture x86_64:
"___cxa_deleted_virtual"
This adds a fix to export the needed symbols.
Test:
> lit -sv test/libcxx/language.support/cxa_deleted_virtual.pass.cpp
