AddressSanitizer on the other hand is created on compile-time and inserts error-checking code inline into a program during compilation. Memcheck, like all Valgrind tools, uses binary translation and instrumentation to run code manipulating the shadow memory corresponding to program memory use. Memcheck for instance tracks values with bit precision, while AddressSanitizer, part of the clang compiler, is comparatively very fast. Shadow memory can be both implemented and used a lot of different ways, and have different performance characteristics. It is for instance used by ThreadSanitizer, a data race detector. Use of shadow memory is however not limited to memory-error checkers, as what information is stored in these shadow bytes is not fixed. Memcheck, part of the Valgrind suite, uses this to detect undefined behavior resulting from acting on or printing undefined memory values. An error checker may also store additional information on memory such as which bits have been defined and which ones do not. This shadow memory is then used for detecting and reporting incorrect accesses of memory, even though the program may not be crashing due to a segmentation fault or similar. The technique is utilized by memory-error checkers that can store information on which parts of memory have been allocated to the program being checked. These shadow bytes are typically invisible to the original program and are used to record information about the original piece of data. Shadow memory consists of shadow bytes that map to individual bits or one or more bytes in main memory. In computing, shadow memory is a technique used to track and store information on computer memory used by a program during its execution.
