* Overhaul the symbolizer interface.Peter Collingbourne2013-10-25
| | | | | | | | | | | | | | | | | | | | | | This moves away from creating the symbolizer object and initializing the external symbolizer as separate steps. Those steps now always take place together. Sanitizers with a legacy requirement to specify their own symbolizer path should use InitSymbolizer to initialize the symbolizer with the desired path, and GetSymbolizer to access the symbolizer. Sanitizers with no such requirement (e.g. UBSan) can use GetOrInitSymbolizer with no need for initialization. The symbolizer interface has been made thread-safe (as far as I can tell) by protecting its member functions with mutexes. Finally, the symbolizer interface no longer relies on weak externals, the introduction of which was probably a mistake on my part.

* Switch __ARM_ARCH_7S__ to __ARM_ARCH_EXT_IDIV__ for use of sdiv/udiv assembly.Stephen Hines2013-10-25
| | | | | | | | | __ARM_ARCH_EXT_IDIV__ is the define that ARM is using to indicate the presence of hardware integer divide (sdiv/udiv). Previously, this code was only being invoked for processors marked 7S. We now can correctly generate hardware divides on cortex-a15 devices. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@193392 91177308-0d34-0410-b5e6-96231b3b80d8

* [msan] Fix invalid origin copying.Evgeniy Stepanov2013-10-24
| | | | | | | | | | | | | | | Origin copying may destroy valid origin info. This is caused by __msan_copy_origin widening the address range to the nearest 4-byte aligned addresses both on the left and on the right. If the target buffer is uninitialized and the source is fully initialized, this will result in overriding valid origin of target buffer with stale (possibly 0) origin of the source buffer. With this change the widened origin is copied only if corresponding shadow values are non zero. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@193338 91177308-0d34-0410-b5e6-96231b3b80d8
