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

4 # This file sets the following shell variables:
5 #  gdb_host_cpu                 generic name of host's CPU
6 #  gdb_host                     name of GDB host definition to use
7 #  gdb_host_float_format        host's float floatformat, or 0
8 #  gdb_host_double_format       host's double floatformat, or 0
9 #  gdb_host_long_double_format  host's long double floatformat, or 0
10
11 # Map host cpu into the config cpu subdirectory name.
12 # The default is $host_cpu.
