Gor Nishanov	a7eae488f2	[Coroutines] Part 15a: Lower coro.subfn.addr in CoroCleanup ... Summary: Not all coro.subfn.addr intrinsics can be eliminated in CoroElide through devirtualization. Those that remain need to be lowered in CoroCleanup.

Gor Nishanov	6ff9c199ca	[Coroutines] Part13: Handle single edge PHINodes across suspends ... Summary: If one of the uses of the value is a single edge PHINode, handle it. Original: %val = something <suspend> %p = PHINode [%val] After Spill + Part13: %val = something %slot = gep val.spill.slot store %val, %slot <suspend> %p = load %slot Plus tiny fixes/changes: * use correct index for coro.free in CoroCleanup * fixup id parameter in coro.free to allow authoring coroutine in plain C with __builtins Reviewers: majnemer Subscribers: mehdi_amini, llvm-commits Differential Revision: https://reviews.llvm.org/D24242 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@281020 91177308-0d34-0410-b5e6-96231b3b80d8	2016-09-09 05:39:00 +00:00
Gor Nishanov	6795b93241	[Coroutines] Part 7: Split coroutine into subfunctions ... Summary: This patch adds simple coroutine splitting logic to CoroSplit pass. Documentation and overview is here: http://llvm.org/docs/Coroutines.html. Upstreaming sequence (rough plan) 1.Add documentation. (https://reviews.llvm.org/D22603) 2.Add coroutine intrinsics. (https://reviews.llvm.org/D22659) ... 7. Split coroutine into subfunctions <= we are here 8. Coroutine Frame Building algorithm 9. Handle coroutine with unwinds 10+.

David Majnemer	880190560d	[coroutines] Part 3 of N: Adding Boilerplate for Coroutine Passes ... This adds boilerplate code for all coroutine passes, the passes are no-ops for now. Also, a small test has been added to verify that passes execute in the expected order or not at all if coroutine support is disabled. Patch by Gor Nishanov!
