# Mapping of configurations into GDB host definitions.  This is
# invoked from the autoconf generated configure script.

# This file sets the following shell variables:
#  gdb_host_cpu			generic name of host's CPU
#  gdb_host			name of GDB host definition to use
#  gdb_host_float_format	host's float floatformat, or 0
#  gdb_host_double_format	host's double floatformat, or 0
#  gdb_host_long_double_format	host's long double floatformat, or 0
#  gdb_host_obs			host-specific .o files to include

# Map host cpu into the config cpu subdirectory name.
# The default is $host_cpu.
