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.
36
37# You can get the latest version of this script from:
38# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
39
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.
47
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.
54
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57# superseded or lifted in POSIX.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.
