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