* 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
* Re-sort #include lines for unittests. This uses a slightly modifiedChandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | clang-format (https://reviews.llvm.org/D33932) to keep primary headers at the top and handle new utility headers like 'gmock' consistently with other utility headers. No other change was made. I did no manual edits, all of this is clang-format. This should allow other changes to have more clear and focused diffs, and is especially motivated by moving some headers into more focused libraries. llvm-svn: 304786
* Retry: [BPI] Use a safer constructor to calculate branch probabilitiesVedant Kumar2016-12-171-0/+88
| | | | | | | | | | | | | | | | | | | BPI may trigger signed overflow UB while computing branch probabilities for cold calls or to unreachables. For example, with our current choice of weights, we'll crash if there are >= 2^12 branches to an unreachable. Use a safer BranchProbability constructor which is better at handling fractions with large denominators. Changes since the initial commit: - Use explicit casts to ensure that multiplication operands are 64-bit ints. rdar://problem/29368161 Differential Revision: https://reviews.llvm.org/D27862 llvm-svn: 290022
