* [SCEV] Pass NoWrapFlags when expanding an AddExprSam Parker2019-06-141-1/+1
| | | | | | | | | | | | InsertBinop now accepts NoWrapFlags, so pass them through when expanding a simple add expression. This is the first re-commit of the functional changes from rL362687, which was previously reverted. Differential Revision: https://reviews.llvm.org/D61934 llvm-svn: 363364
* Revert "[SCEV] Use wrap flags in InsertBinop"Benjamin Kramer2019-06-061-1/+1
| | | | | | This reverts commit r362687. Miscompiles llvm-profdata during selfhost. llvm-svn: 362699

| | | | | | | | | | If the given SCEVExpr has no (un)signed flags attached to it, transfer these to the resulting instruction or use them to find an existing instruction. Differential Revision: https://reviews.llvm.org/D61934 llvm-svn: 362687

| | | | | | | | The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552
* Temporarily Revert "Add basic loop fusion pass."Eric Christopher2019-04-171-136/+0
| | | | | | | | As it's causing some bot failures (and per request from kbarton). This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda. llvm-svn: 358546

| | | | | | | | | | | | | | | | | | | | | | | | | | pass manager There are two nontrivial details here: * Loop structure update interface is quite different with new pass manager, so the code to add new loops was factored out * BranchProbabilityInfo is not a loop analysis, so it can not be just getResult'ed from within the loop pass. It cant even be queried through getCachedResult as LoopCanonicalization sequence (e.g. LoopSimplify) might invalidate BPI results. Complete solution for BPI will likely take some time to discuss and figure out, so for now this was partially solved by making BPI optional in IRCE (skipping a couple of profitability checks if it is absent). Most of the IRCE tests got their corresponding new-pass-manager variant enabled. Only two of them depend on BPI, both marked with TODO, to be turned on when BPI starts being available for loop passes.

* [IRCE] Fix SCEVExpander's usage in IRCEMax Kazantsev2017-11-161-0/+135
When expanding exit conditions for pre- and postloops, we may end up expanding a recurrency from the loop to in its loop's preheader. This produces incorrect IR. This patch ensures that IRCE uses SCEVExpander correctly and only expands code which is safe to expand in this particular location.
