# 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.
# When you change the cases in the OS or target switches, consider
# updating ../libgcc/config.host also.
# 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
# The default value for the $enable___cxa_atexit
# variable. enable___cxa_atexit needs to be set to
# "yes" for the correct operation of C++ destructors
# but it relies upon the presence of a non-standard C
# library function called __cxa_atexit.
# Since not all C libraries provide __cxa_atexit the
# default value of $default_use_cxa_atexit is set to
# "no" except for targets which are known to be OK.
#
# default_gnu_indirect_function
# The default value for the $enable_gnu_indirect_function
# variable. enable_gnu_indirect_function relies
# upon the presence of a non-standard gnu ifunc support
# in the assembler, linker and dynamic linker.
# Since not all libraries provide the dynamic linking
# support, the default value of
# $default_gnu_indirect_function is set to
# "no" except for targets which are known to be OK.
#
# gas_flag Either yes or no depending on whether GNU as was
# requested.
#
# gnu_ld_flag Either yes or no depending on whether GNU ld was
# requested.
# This file sets the following shell variables for use by the
# autoconf-generated configure script:
#
# cpu_type The name of the cpu, if different from the first
# chunk of the canonical target name.
#
# tm_defines List of target macros to define for all compilations.
#
# tm_file A list of target macro files, if different from
# "$cpu_type/$cpu_type.h". Usually it's constructed
# per target in a way like this:
# tm_file="${tm_file} dbxelf.h elfos.h ${cpu_type.h}/elf.h"
# Note that the preferred order is:
# - specific target header "${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}.
#
# It is possible to include automatically-generated
# build-directory files by prefixing them with "./".
# All other files should relative to $srcdir/config.
#
# 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}.
#
# user_headers_inc_next_pre
# List of header file names of internal gcc header
# files, which should be prefixed by an include_next.
# user_headers_inc_next_post
# List of header file names of internal gcc header
# files, which should be postfixed by an include_next.
# use_gcc_tgmath If set, add tgmath.h to the list of used header
# files.
#
# use_gcc_stdint If "wrap", install a version of stdint.h that
# wraps the system's copy for hosted compilations;
# if "provide", provide a version of systems without
# such a system header; otherwise "none", do not
# provide such a header at all.
#
# 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.
#
# extra_options List of target-dependent .opt files.
#
# 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.
#
# fortran_target_objs List of extra target-dependent objects that be
# linked into the fortran 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 if this target
# supports "long" or "wchar_t" wider than 32 bits,
# or BITS_PER_WORD is wider than 32 bits.
# The setting made here must match the one made in
# other locations such as libcpp/configure.ac
#
# configure_default_options
# Set to an initializer for configure_default_options
# in configargs.h, based on --with-cpu et cetera.
# 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.
