35 # Usage: config.sub CPU-VENDOR-OS
38 # Validate and canonicalize the given configuration name, with special
39 # handling for GMP extra CPU names.
41 # When the CPU isn't special the whole name is simply passed straight
42 # through to configfsf.sub.
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".
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".
54 # Expect to find configfsf.sub in the same directory as this config.sub
