# This is the GCC build-, host- and target-specific configuration file
# where a configuration type, as recognized and generated by config.bfd,
# is mapped to different system-specific definitions and files.  This is
# invoked by the autoconf-generated configure script, called for build,
# host and target in that order, setting ${machine} to each.  Putting it
# in a separate shell file lets us skip running autoconf when modifying
# build-, host- and target-specific information.

# This file switches on the shell variable ${machine}, and also uses the
# following shell variables:
#
#  with_*               Various variables as set by configure.
#
#  enable_threads_flag  Either the name, yes or no depending on whether
#                       threads support was requested.
#
#  gas_flag             Either yes or no depending on whether GNU as was
#                       requested.
#
#  gnu_ld_flag          Either yes or no depending on whether GNU ld was
#                       requested.

# This file sets the following shell variables for use by the
# autoconf-generated configure script:
#
#  cpu_type             The name of the cpu, if different from machine.
#
#  tm_defines           List of target macros to define for all compilations.
#
#  tm_file              A list of target macro files, if different from
#                       "$cpu_type/$cpu_type.h". Usually it's constructed
#                       per target in a way like this:
#                       tm_file="${tm_file} dbxelf.h elfos.h svr4.h ${cpu_type.h}/elf.h"
#                       Note that the preferred order is:
#                       - specific target header "${cpu_type}/${cpu_type.h}"
#                       - generic headers like dbxelf.h elfos.h, netware.h, etc.
#                       - specializing target headers like ${cpu_type.h}/elf.h
#                       This helps to keep OS specific stuff out of the CPU
#                       defining header ${cpu_type}/${cpu_type.h}.
#
#  tm_p_file            Location of file with declarations for functions
#                       in $out_file.
#
#  out_file             The name of the machine description C support
#                       file, if different from "$cpu_type/$cpu_type.c".
#
#  md_file              The name of the machine-description file, if
#                       different from "$cpu_type/$cpu_type.md".
#
#  tmake_file           A list of machine-description-specific
#                       makefile-fragments, if different from
#                       "$cpu_type/t-$cpu_type".
#
#  extra_modes          The name of the file containing a list of extra
#                       machine modes, if necessary and different from
#                       "$cpu_type/$cpu_type-modes.def".
#
#  float_format         Set to the symbolic name for the floating-point
#                       formats used for this machine, if different from
#                       "i64".  Used to derive a header file name to
#                       include, like "vax" for "float-vax.h".  If no such
#                       file is wanted, set to "none".
#
#  extra_objs           List of extra objects that should be linked into
#                       the compiler proper (cc1, cc1obj, cc1plus)
#                       depending on target.
#
#  extra_headers        List of used header files from the directory
#                       config/${cpu_type}.
#
#  host_xmake_file      List of host-specific makefile-fragments.
#
#  extra_passes         List of extra executables compiled for this target
#                       machine, used for compiling from source to object.
#
#  extra_parts          List of extra object files that should be compiled
#                       for this target machine.
#
#  extra_programs       Like extra_passes, but these are used when linking.
#
#  host_extra_objs      List of extra host-dependent objects that should
#                       be linked into the compiler proper.
#
#  host_extra_gcc_objs  List of extra host-dependent objects that should
#                       be linked into the gcc driver.
#

#                       linked into the C++ compiler only.

#                       on this host, due to filename length issues.
#
#  gdb_needs_out_file_path
#                       Set to yes if gdb needs a dir command with
