# This is the GCC target-specific configuration file
# where a configuration type is mapped to different system-specific
# definitions and files.  This is invoked by the autoconf-generated
# configure script.  Putting it in a separate shell file lets us skip
# running autoconf when modifying target-specific information.

# This file switches on the shell variable ${target}, and also uses the
# following shell variables:
#
#  with_*               Various variables as set by configure.
#
#  enable_threads       Either the name, yes or no depending on whether
#                       threads support was requested.
#
#  default_use_cxa_atexit
#                       "no" by default, can be set to "yes" if a target
#                       wishes to use __cxa_atexit() by default if the
#                       $enable___cxa_atexit variable is not set.
#
#  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 the first
#                       chunk of the canonical target name.
#
#  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, 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/$cpu_type-modes.def".
#
#  extra_objs           List of extra objects that should be linked into
#                       the compiler proper (cc1, cc1obj, cc1plus)
#                       depending on target.
#
#  extra_gcc_objs       List of extra objects that should be linked into
#                       the compiler driver (gcc) depending on target.
#
#  extra_headers        List of used header files from the directory
#                       config/${cpu_type}.
#
#  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.
#
#  c_target_objs        List of extra target-dependent objects that be
#                       linked into the C compiler only.
#
#  cxx_target_objs      List of extra target-dependent objects that be
#                       linked into the C++ compiler only.
#
#  target_gtfiles       List of extra source files with type information.
#
#  xm_defines           List of macros to define when compiling for the
#                       target machine.
#
#  xm_file              List of files to include when compiling for the
#                       target machine.
#
#  use_collect2         Set to yes or no, depending on whether collect2
#                       will be used.
#
#  target_cpu_default   Set to override the default target model.
#
#  gdb_needs_out_file_path
#                       Set to yes if gdb needs a dir command with
#                       `dirname $out_file`.
#
#  thread_file          Set to control which thread package to use.
#
#  gas                  Set to yes or no depending on whether the target
#                       system normally uses GNU as.
#
#  need_64bit_hwint     Set to yes if HOST_WIDE_INT must be 64 bits wide
#                       for this target.  This is true iff this target
#                       supports "long" or "wchar_t" wider than 32 bits.
#
#  configure_default_options
#                       Set to an initializer for configure_default_options
#                       in configargs.h, based on --with-cpu et cetera.
#
#  use_fixproto         Set to "yes" if fixproto should be run normally,
#                       "no" if fixproto should never be run.

# The following variables are used in each case-construct to build up the
# outgoing variables:
#
#  gnu_ld               Set to yes or no depending on whether the target
#                       system normally uses GNU ld.
