* Make SourceManager::createFileID(UnownedTag, ...) take a const ↵Nico Weber2019-04-041-2/+2
| | | | | | | | | | | | | | | | | | | | | llvm::MemoryBuffer* Requires making the llvm::MemoryBuffer* stored by SourceManager const, which in turn requires making the accessors for that return const llvm::MemoryBuffer*s and updating all call sites. The original motivation for this was to use it and fix the TODO in CodeGenAction.cpp's ConvertBackendLocation() by using the UnownedTag version of createFileID, and since llvm::SourceMgr* hands out a const llvm::MemoryBuffer* this is required. I'm not sure if fixing the TODO this way actually works, but this seems like a good change on its own anyways. No intended behavior change.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8

* [analyzer] Use the signature of the primary template for issue hash calculationGabor Horvath2017-10-301-0/+7
| | | | | | | | | | | | | | Now when a template is instantiated more times and there is a bug found in the instantiations the issue hash will be different for each instantiation even if every other property of the bug (path, message, location) is the same. This patch aims to resolve this issue. Note that explicit specializations still generate different hashes but that is intended.

* [analyzer] Fix an assertion fail in hash generation.Gabor Horvath2016-03-301-2/+5
| | | | | | | | | | | | | | In case the (uniqueing) location of the diagnostic is in a line that only contains whitespaces there was an assertion fail during issue hash generation. Unfortunately I am unable to reproduce this error with the built in checkers, so no there is no failing test case with this patch. It would be possible to write a debug checker for that purpuse but it does not worth the effort.

* [analyzer] Bug identificationGabor Horvath2015-10-221-0/+193
This patch adds hashes to the plist and html output to be able to identfy bugs for suppressing false positives or diff results against a baseline. This hash aims to be resilient for code evolution and is usable to identify bugs in two different snapshots of the same software. One missing piece however is a permanent unique identifier of the checker that produces the warning. Once that issue is resolved, the hashes generated are going to change. Until that point this feature is marked experimental, but it is suitable for early adoption.
