30# This file provides exceptions to the usual rules applied to ELF objects by
31# check_rtime. All strings are Perl regular expressions that are compared to
32# file paths. In addition to the standard Perl syntax, there is one extension:
33#
34#	MACH(dir)
35#
36# is expanded into a regular expression that matches the given
37# directory, or a 64-bit subdirectory of the directory with the
38# name of a 64-bit architecture. For example, MACH(lib) will match
