address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function. When building with AddressSanitizer, add AddressSafety function attribute to every generated function except for those that have __attribute__((no_address_safety_analysis)). With this patch we will be able to 1. disable AddressSanitizer for a particular function 2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on. llvm-svn: 148842
