* Revert r75581: it causes massive breakage in the AdaDuncan Sands2009-07-231-0/+23
| | | | | | | | | | | | | | | | | testsuite, due to exception handling not working correctly. Maybe because the libgcc unwinder is miscompiled - not sure, and I won't have time to look into it before leaving on holiday. Note that miscompilations of libgcc are not picked up by the nightly testers, because they dynamically link with libgcc, so pick up the system version rather than the version built as part of llvm-gcc. This is a nasty flaw in the nightly testers. (On the other hand the Ada testsuite links with the just built libgcc). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76895 91177308-0d34-0410-b5e6-96231b3b80d8
