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line above the timestamp inhibits complaints # about features and limitations of the classic Bourne shell that were # superseded or lifted in POSIX.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