* Revert "Revert "DI: Fold constant arguments into a single MDString""Duncan P. N. Exon Smith2014-10-031-7/+7
| | | | | | | | | | | | | | | | | | | | | | This reverts commit r218918, effectively reapplying r218914 after fixing an Ocaml bindings test and an Asan crash. The root cause of the latter was a tightened-up check in `DILexicalBlock::Verify()`, so I'll file a PR to investigate who requires the loose check (and why). Original commit message follows. -- This patch addresses the first stage of PR17891 by folding constant arguments together into a single MDString. Integers are stringified and a `\0` character is used as a separator. Part of PR17891. Note: I've attached my testcases upgrade scripts to the PR. If I've just broken your out-of-tree testcases, they might help. llvm-svn: 219010

* Add diagnostics to the vectorizer cost model.Tyler Nowicki2014-08-021-0/+58
When the cost model determines vectorization is not possible/profitable these remarks print an analysis of that decision. Note that in selectVectorizationFactor() we can assume that OptForSize and ForceVectorization are mutually exclusive. Reviewed by Arnold Schwaighofer llvm-svn: 214599
