Fangrui Song	1daa48f005	[lsan] realloc: don't deallocate if requested size is too large ... This is the behavior required by the standards. Differential Revision: https://reviews.llvm.org/D99480	2021-03-29 13:35:10 -07:00
Dan Liew	dd922bc2a6	[LSan] Introduce a callback mechanism to allow adding data reachable from ThreadContexts to the frontier. ... This mechanism is intended to provide a way to treat the `arg` pointer of a created (but not yet started) thread as reachable. In future patches this will be implemented in `GetAdditionalThreadContextPtrs`. A separate implementation of `GetAdditionalThreadContextPtrs` exists for ASan and LSan runtimes because they need to be implemented differently in future patches. rdar://problem/63537240 Differential Revision: https://reviews.llvm.org/D95183	2021-01-22 19:26:02 -08:00
