Author: ericwf Date: Sun Sep 17 13:59:43 2017 New Revision: 313500 URL: http://llvm.org/viewvc/llvm-project?rev=313500&view=rev Log: ABI: Fix for undefined "___cxa_deleted_virtual" symbol in MacOSX
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.
