# configure.host

#

# This shell script handles all host based configuration for libgfortran.

# It sets various shell variables based on the the host triplet.

# You can modify this shell script without rerunning autoconf/aclocal/etc.

# This file is "sourced", not executed.

#

#

# It uses the following shell variables as set by config.guess:

#   host                The configuration host (full CPU-vendor-OS triplet)

#   host_cpu            The configuration host CPU

#   host_os             The configuration host OS

#

#

# It sets the following shell variables:

#

#   fpu_host            FPU-specific code file, defaults to fpu-generic.

# DEFAULTS

fpu_host='fpu-generic'
