Hugh Bellamy	397f25e43b	Use LLVM_ATTRIBUTE_NOINLINE instead of __attribute__((noinline))	2017-01-14 12:46:14 +00:00
Arnold Schwaighofer	d6dd8e83bc	Hack to workaround a clang lto bug ... We hit an assert in AllocStackHoisting that is only triggered in a release lto build. Clang forwards the read of parent basic block of 'AssignedLoc' in the next statement: auto *EntryBB = AssignedLoc->getFunction()->getEntryBlock(); // read AssignedLoc->ParentBB AssignedLoc->removeFromParent(); // writes AssignedLoc->ParentBB To this read: EntryBB->push_front(AssignedLoc); // read AssignedLoc->ParentBB and assert if non-null, *should reload* As a temporary workaround outline code to prevent the miscompile. rdar://29982182	2017-01-13 08:42:02 -08:00

Arnold Schwaighofer	9a2582f7a4	Remove to strict assert ... unreachable exits don't need an dealloc_stack and so there can be alloc_stack instructions without a matching dealloc_stack	2016-12-20 17:02:26 -08:00

Arnold Schwaighofer	f1c2dcf1fa	Add an alloc_stack hoisting pass. ... Hoist alloc_stack instructions of 'generic' or resilient type to the entry block. At the same time also perform a very simple stack coloring analysis. This does not use a true liveness-analysis yet but rather employs some simple conservative checks to see whether the live ranges of two alloc_stacks might interfere. AllocStackHoisting is an IRGen SIL pass. This allows for using IRGen's type lowering information. Furthermore, hoisting and merging the alloc_stack instructions this late does not interfere with SIL optimizations because the resulting SIL never gets serialized.	2016-12-20 07:51:55 -08:00
