# Usage: config.sub CPU-VENDOR-OS

#        config.sub ALIAS

#

# Validate and canonicalize the given configuration name, with special

# handling for GMP extra CPU names.

#

# When the CPU isn't special the whole name is simply passed straight

# through to configfsf.sub.

#

# When the CPU is a GMP extra, configfsf.sub is run on a similar CPU that it

# will recognise.  For example "athlon-pc-freebsd3.5" is validated using

# "i386-pc-freebsd3.5".

#

# Any canonicalizations made by configfsf.sub are preserved.  For example

# given "athlon-linux", configfsf.sub is called with "i386-linux" and will

# give back "i386-pc-linux-gnu".  "athlon" is then reinstated, so we print

# "athlon-pc-linux-gnu".

# Expect to find configfsf.sub in the same directory as this config.sub
