Duncan P. N. Exon Smith a582f1f396 IR: Handle self-referencing DICompositeTypes in DIBuilder ... Add API to DIBuilder to handle self-referencing `DICompositeType`s. Self-references aren't expected in the debug info graph, and we take advantage of that by only calling `resolveCycles()` on nodes that were once forward declarations (otherwise, DIBuilder needs an expensive tracking reference to every unresolved node it creates, which in cyclic graphs is *all of them*). However, clang seems to create self-referencing `DICompositeType`s. Add API to manage this safely. The paired commit to clang will include the regression test. I'll make the `DICompositeType` API `private` in a follow-up to prevent misuse (I've separated that to prevent build failures from missing the clang commit). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224482 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-18 00:46:16 +00:00
