Sanitizer Scripts Rework
How sanitizers work has been completely changed internally.
Sanitizers and their options are now declared via calling the set_sanitizer_options() function, and applying sanitizers to be used is via the new add_sanitizer_support() call.
Whether sanitizers are available/supported is no longer a function of the script inferring via the compiler/platform, but instead by checking whether the flags are available on the compiler no matter the platform.
DEPRECATED
The ability to use sanitizers via the global USE_SANITIZER variable is now deprecated and will be removed in a future release.
To maintain the same behaviour after removal, add this to CMake scripts file after including the sanitizers file:
if(NOT MSVC)
set(SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS -fno-omit-frame-pointer)
endif()
set_sanitizer_options(address DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(leak DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(memory DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(memorywithorigins DEFAULT SANITIZER memory
-fsanitize-memory-track-origins ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(undefined DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(thread DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set_sanitizer_options(cfi DEFAULT ${SANITIZER_LEGACY_DEFAULT_COMMON_OPTIONS})
set(USE_SANITIZER
""
CACHE
STRING
"Compile with sanitizers. Available sanitizers are: ${SANITIZERS_AVAILABLE_LIST}"
)
if(USE_SANITIZER)
add_sanitizer_support(${USE_SANITIZER})
endif()
