  35 # Usage: config.sub CPU-VENDOR-OS
  36 #        config.sub ALIAS
  37 #
  38 # Validate and canonicalize the given configuration name, with special
  39 # handling for GMP extra CPU names.
  40 #
  41 # When the CPU isn't special the whole name is simply passed straight
  42 # through to configfsf.sub.
  43 #
  44 # When the CPU is a GMP extra, configfsf.sub is run on a similar CPU that it
  45 # will recognise.  For example "athlon-pc-freebsd3.5" is validated using
  46 # "i386-pc-freebsd3.5".
  47 #
  48 # Any canonicalizations made by configfsf.sub are preserved.  For example
  49 # given "athlon-linux", configfsf.sub is called with "i386-linux" and will
  50 # give back "i386-pc-linux-gnu".  "athlon" is then reinstated, so we print
  51 # "athlon-pc-linux-gnu".
