2013-10-25Overhaul the symbolizer interface.Peter Collingbourne
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.

shrink the binary size of the ubsan runtime. Also fix a bug where long-running processes could eventually trigger a crash in the runtime by filling up the cache.

2013-03-20Split ubsan runtime into three pieces (compiler-rt part):Richard Smith
* libclang_rt-san-* is sanitizer_common, and is linked in only if no other sanitizer runtime is present. * libclang_rt-ubsan-* is the piece of the runtime which doesn't depend on a C++ ABI library, and is always linked in. * libclang_rt-ubsan_cxx-* is the piece of the runtime which depends on a C++ ABI library, and is only linked in when linking a C++ binary. The Darwin ubsan runtime is unchanged. For more details, see Clang change r177605. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@177606 91177308-0d34-0410-b5e6-96231b3b80d8
