DITypeArray is an array of DITypeRef, at its creation, we will create DITypeRef (i.e use the identifier if the type node has an identifier). This is the last patch to unique the type array of a subroutine type. rdar://17628609 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214132 91177308-0d34-0410-b5e6-96231b3b80d8
