-Subject: [PATCH] Cloning: Reduce complexity of debug info cloning and fix
- correctness issue.
-
-Commit r260791 contained an error in that it would introduce a cross-module
-reference in the old module. It also introduced O(N^2) complexity in the
-module cloner by requiring the entire module to be visited for each function.
-Fix both of these problems by avoiding use of the CloneDebugInfoMetadata
-function (which is only designed to do intra-module cloning) and cloning
-function-attached metadata in the same way that we clone all other metadata.
-
-Differential Revision: http://reviews.llvm.org/D18583

-git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@264935 91177308-0d34-0410-b5e6-96231b3b80d8

-Alpine maintainer notes:
-  - Corresponds to llvm-D17165-D18583.patch in Julia.
