32 # Configuration subroutine to validate and canonicalize a configuration type.
33 # Supply the specified configuration type as an argument.
34 # If it is invalid, we print an error message on stderr and exit with code 1.
35 # Otherwise, we print the canonical config type on stdout and succeed.
37 # You can get the latest version of this script from:
38 # https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
40 # This file is supposed to be the same for all GNU packages
41 # and recognize all the CPU types, system types and aliases
42 # that are meaningful with *any* GNU software.
43 # Each package is responsible for reporting which valid configurations
44 # it does not support. The user should be able to distinguish
45 # a failure to support a valid configuration from a meaningless
46 # configuration.
48 # The goal of this file is to map all the various variations of a given
49 # machine specification into a single specification in the form:
50 # CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
51 # or in some cases, the newer four-part form:
52 # CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
53 # It is wrong to echo any other type of specification.
55 # The "shellcheck disable" line above the timestamp inhibits complaints
56 # about features and limitations of the classic Bourne shell that were
57 # superseded or lifted in POSIX. However, this script identifies a wide
58 # variety of pre-POSIX systems that do not have POSIX shells at all, and
59 # even some reasonably current systems (Solaris 10 as case-in-point) still
60 # have a pre-POSIX /bin/sh.
