2019-08-22	IR. Change strip* family of functions to not look through aliases.	Peter Collingbourne	1	-2/+2
	I noticed another instance of the issue where references to aliases were being replaced with aliasees, this time in InstCombine. In the instance that I saw it turned out to be only a QoI issue (a symbol ended up being missing from the symbol table due to the last reference to the alias being removed, preventing HWASAN from symbolizing a global reference), but it could easily have manifested as incorrect behaviour. Since this is the third such issue encountered (previously: D65118, D65314) it seems to be time to address this common error/QoI issue once and for all and make the strip* family of functions not look through aliases. Includes a test for the specific issue that I saw, but no doubt there are other similar bugs fixed here. As with D65118 this has been tested to make sure that the optimization isn't load bearing. I built Clang, Chromium for Linux, Android and Windows as well as the test-suite and there were no size regressions. Differential Revision: https://reviews.llvm.org/D66606 llvm-svn: 369697
2019-03-01	Hide two unused debugging methods, NFCI.	Jonas Hahnfeld	1	-0/+4
	GCC correctly moans that PlainCFGBuilder::isExternalDef(llvm::Value*) and StackSafetyDataFlowAnalysis::verifyFixedPoint() are defined but not used in Release builds. Hide them behind 'ifndef NDEBUG'. llvm-svn: 355205
2019-01-19	Update the file headers across all of the LLVM projects in the monorepo	Chandler Carruth	1	-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
2018-12-21	[IR] Add Instruction::isLifetimeStartOrEnd, NFC	Vedant Kumar	1	-5/+2
	Instruction::isLifetimeStartOrEnd() checks whether an Instruction is an llvm.lifetime.start or an llvm.lifetime.end intrinsic. This was suggested as a cleanup in D55967. Differential Revision: https://reviews.llvm.org/D56019 llvm-svn: 349964

2018-11-26	[stack-safety] Inter-Procedural Analysis implementation	Vitaly Buka	1	-4/+203
	Summary: IPA is implemented as module pass which produce map from Function or Alias to StackSafetyInfo for a single function. From prototype by Evgenii Stepanov and Vlad Tsyrklevich.
