// This macro is used to abort the program abnormally while providing additional diagnostic information.
//
// The first argument is a printf-style format string, and the remaining arguments are values to format
// into the format-string. This macro can be customized by users to provide fine-grained control over
// how verbose termination is triggered.
//
// If the user does not supply their own version of the _LIBCPP_VERBOSE_ABORT macro, we pick the default
// behavior based on whether we know the built library we're running against provides support for the
// verbose termination handler or not. If it does, we call it. If it doesn't, we call __builtin_abort to
// make sure that the program terminates but without taking any complex dependencies in this header.
