* [Hexagon] Fix reuse bug in Vector Loop Carried Reuse passBrendon Cahoon2019-04-121-3/+10
| | | | | | | | | | | | | | | The Hexagon Vector Loop Carried Reuse pass was allowing reuse between two shufflevectors with different masks. The reason is that the masks are not instruction objects, so the code that checks each operand just skipped over the operands. This patch fixes the bug by checking if the operands are the same when they are not instruction objects. If the objects are not the same, then the code assumes that reuse cannot occur.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-18/+21
| | | | | | | | | | | | | | | | The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM - Manual change to APInt - Manually chage DOCS as regex doesn't match it. In the transition period the DEBUG() macro is still present and aliased to the LLVM_DEBUG() one. Differential Revision: https://reviews.llvm.org/D43624 llvm-svn: 332240

* Enable the reuse of values computed in a previous loop iteration.Pranav Bhandarkar2017-09-211-0/+579
This patch adds a pass that removes the computation of provably redundant expressions that have been computed earlier in a previous iteration. It relies on the use of PHIs to identify loop carried dependences. This is scalar replacement for vector types. llvm-svn: 313925
