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:
34#
35#	MACH(dir)
36#
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:

205# Furthermore, the Sun compiler and gcc use different and incompatible
