Duncan P. N. Exon Smith	83902832de	Revert "Revert "DI: Fold constant arguments into a single MDString"" ... 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@219010 91177308-0d34-0410-b5e6-96231b3b80d8	2014-10-03 20:01:09 +00:00

Sanjay Patel	87c977a52b	Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option names controlling this variable. ... "Unroll" is not the appropriate name for this variable. Clang already uses the term "interleave" in pragmas and metadata for this.

Tyler Nowicki	d5a8fa72bb	Add Rpass-missed and Rpass-analysis reports to the loop vectorizer. The remarks give the vector width of vectorized loops and a brief analysis of loops that fail to be vectorized. For example, an analysis will be generated for loops containing control flow that cannot be simplified to a select. The optimization remarks also give the debug location of expressions that cannot be vectorized, for example the location of an unvectorizable call. ...

Diego Novillo	10ec44d87a	Add new debug kind LocTrackingOnly. ... Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-pass-remarks, -pass-remarks-missed and -pass-remarks-analysis). To prevent debug info emission, DIBuilder never inserts the annotation 'llvm.dbg.cu' when LocTrackingOnly is enabled.

Diego Novillo	55deff895d	Fix vectorization remarks. ... This patch changes the vectorization remarks to also inform when vectorization is possible but not beneficial. Added tests to exercise some loop remarks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207574 91177308-0d34-0410-b5e6-96231b3b80d8	2014-04-29 20:06:10 +00:00
