Alexander Potapenko 3544b0e869 [MSan] run materializeChecks() before materializeStores() ... When pointer checking is enabled, it's important that every pointer is checked before its value is used. For stores MSan used to generate code that calculates shadow/origin addresses from a pointer before checking it. For userspace this isn't a problem, because the shadow calculation code is quite simple and compiler is able to move it after the check on -O2. But for KMSAN getShadowOriginPtr() creates a runtime call, so we want the check to be performed strictly before that call. Swapping materializeChecks() and materializeStores() resolves the issue: both functions insert code before the given IR location, so the new insertion order guarantees that the code calculating shadow address is between the address check and the memory access. llvm-svn: 337571		2018-07-20 16:28:49 +00:00
