* Revert "Temporarily Revert "Add basic loop fusion pass.""Eric Christopher2019-04-171-0/+71
| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-71/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546
* Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option ↵Sanjay Patel2014-09-101-1/+1
| | | | | | | | | | | 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. Differential Revision: http://reviews.llvm.org/D5066 llvm-svn: 217528
* Force a fixed unroll count on the target independent tests.Nadav Rotem2013-01-051-1/+1
| | | | | | This should fix clang-native-arm-cortex-a9. Thanks Renato. llvm-svn: 171582

| | | | | | | | The bug was in the code that detects PHIs in if-then-else block sequence. PR14701. llvm-svn: 171008
* LoopVectorizer: Add a basic cost model which uses the VTTI interface.Nadav Rotem2012-10-241-1/+1
| | | | llvm-svn: 166620
* Vectorizer: fix a bug in the classification of induction/reduction phis.Nadav Rotem2012-10-211-0/+15
