31# This file provides exceptions to the usual rules applied to ELF objects by
32# check_rtime. All strings are Perl regular expressions that are compared to
33# file paths. In addition to the standard Perl syntax, there is one extension:
35# MACH(dir)
37# is expanded into a regular expression that matches the given
38# directory, or a 64-bit subdirectory of the directory with the
39# name of a 64-bit architecture. For example, MACH(lib) will match
40# any of the following:
42# lib
43# lib/amd64
