* [Coroutines] Catch exceptions in await_resumeBrian Gesiak2018-05-041-0/+4
| | | | | | | | | | | | | | | | | | | | | Summary: http://wg21.link/P0664r2 section "Evolution/Core Issues 24" describes a proposed change to Coroutines TS that would have any exceptions thrown after the initial suspend point of a coroutine be caught by the handler specified by the promise type's 'unhandled_exception' member function. This commit provides a sample implementation of the specified behavior.

* [MS] Always use base dtors in place of complete/vbase dtors when possibleReid Kleckner2018-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously we tried too hard to uphold the fiction that destructor variants work like they do on Itanium throughout the ABI-neutral parts of clang. This lead to MS C++ ABI incompatiblities and other bugs. Now, -mconstructor-aliases will no longer control this ABI detail, and clang -cc1's LLVM IR output will be this much closer to the clang driver's. Based on a patch by Zahira Ammarguellat: https://reviews.llvm.org/D39063 I've tried to move the logic that Zahira added into MicrosoftCXXABI.cpp. There is only one ABI-specific detail sticking out, and that is in CodeGenModule::getAddrOfCXXStructor, where we collapse complete dtors to base dtors in the MS ABI. This fixes PR32990. Reviewers: erichkeane, zahiraam, majnemer, rjmccall Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D44505 llvm-svn: 327732
