Dmitry Vyukov	abb825725e	tsan: optimize __tsan_read/write16 ... These callbacks are used for SSE vector accesses. In some computational programs these accesses dominate. Currently we do 2 uninlined 8-byte accesses to handle them. Inline and optimize them similarly to unaligned accesses. This reduces the vector access benchmark time from 8 to 3 seconds. Depends on D112603. Reviewed By: melver Differential Revision: https://reviews.llvm.org/D114594	2021-12-21 11:33:28 +01:00
Dmitry Vyukov	2ddaffdc74	tsan: introduce kAccessExternalPC ... Add kAccessExternal memory access flag that denotes memory accesses with PCs that may have kExternalPCBit set. In preparation for MemoryAccess refactoring. Currently unused, but will allow to skip a branch. Depends on D107464.
