19// ASan flag values can be defined in four ways:
20// 1) initialized with default values at startup.
21// 2) overriden during compilation of ASan runtime by providing
22//    compile definition ASAN_DEFAULT_OPTIONS.
23// 3) overriden from string returned by user-specified function
24//    __asan_default_options().
25// 4) overriden from env variable ASAN_OPTIONS.
26// 5) overriden during ASan activation (for now used on Android only).
