602// This macro gives a way for downstream users to override the above
603// interceptor macros irrespective of the platform they are on. They have
604// to do two things:
605// 1. Build compiler-rt with -DSANITIZER_OVERRIDE_INTERCEPTORS.
606// 2. Provide a header file named sanitizer_intercept_overriders.h in the
607// include path for their compiler-rt build.
608// An example of an overrider for strlen interceptor that one can list in
609// sanitizer_intercept_overriders.h is as follows:
610//
611// #ifdef SANITIZER_INTERCEPT_STRLEN
612// #undef SANITIZER_INTERCEPT_STRLEN
613// #define SANITIZER_INTERCEPT_STRLEN <value of choice>
614// #endif
615//
616// This "feature" is useful for downstream users who do not want some of
617// their libc funtions to be intercepted. They can selectively disable
618// interception of those functions.
