The bitcode upgrade I added for DISubprogram in r266446 was based on the assumption that the CU node for the subprogram was already materialized by the time the DISubprogram is visited. This assumption may not hold true as future versions of LLVM may decide to write out bitcode in a different order. This patch corrects this by introducing a versioning bit next to the distinct flag to unambiguously differentiate the new from the old record layouts. Note for people stabilizing LLVM out-of-tree: This patch introduces a bitcode incompatibility with llvm trunk revisions from r266446 — this commit. (But D19987 will ensure that it degrades gracefully). http://reviews.llvm.org/D20004 rdar://problem/26074194 llvm-svn: 268816 |
