Evgeniy Stepanov	d38af30b74	[msan] Better use-after-free reports. ... By attaching an extra integer tag to heap origins, we are able to distinguish between uninits - created by heap allocation, - created by heap deallocation (i.e. use-after-free), - created by __msan_allocated_memory call, - etc. See https://code.google.com/p/memory-sanitizer/issues/detail?id=35. llvm-svn: 226821	2015-01-22 13:33:16 +00:00
Evgeniy Stepanov	a0b6899234	[msan] Fix origin propagation for select of floats. ...
