# 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_file		A list of target macro files, if different from
#			"$cpu_type/$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".
#
#  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
#			ginclude.
#
#  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-dependant objects that should
#			be linked into the compiler proper.
#
#  host_extra_gcc_objs	List of extra host-dependant objects that should
#			be linked into the gcc driver.
#
#  c_target_objs	List of extra target-dependant objects that be
#			linked into the C compiler only.
#  
#  cxx_target_objs	List of extra target-dependant objects that be
#			linked into the C++ compiler only.
#  
#  build_xm_defines	List of macros to define when compiling for the
#			build machine.
#
#  build_xm_file	List of files to include when compiling for the
#			build machine.
#
#  host_xm_defines	List of macros to define when compiling for the
#			host machine.
#
#  host_xm_file		List of files to include when compiling for the
#			host machine.
#
#  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.
#
#  build_install_headers_dir
#			Target to use when installing header files.
#
#  host_truncate_target
#			Non-empty if the target name should be truncated
#			on this host, due to filename length issues.
#
#  gdb_needs_out_file_path
#			Set to yes if gdb needs a dir command with
#			`dirname $out_file`.
#
#  build_exeext		Set to the suffix, if the build machine requires
#			executables to have a file name suffix.
#
#  host_exeext		Set to the suffix, if the host machine requires
#			executables to have a file name suffix.
#
#  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.

# The following variables are used in each case-construct to build up the
# outgoing variables:
#
#  xmake_file		Makefile-fragment when this system is as a host,
#			for host_xmake_file.
#
#  extra_host_objs	List of extra objects that should be linked into
#			the compiler proper when this system is a host,
#			for host_extra_objs.
#
#  install_headers_dir	Makefile-target for how the header file directory
#			is installed, when this system is a build system,
#			for build_install_headers_dir.
#
#  truncate_target	Non-empty if the target name should be truncated
#			when this system is a host, due to filename length
#			issues.  For host_truncate_target.
#
#  exeext		The suffix for executables on this system.
#
#  gnu_ld		Set to yes or no depending on whether the target
#			system normally uses GNU ld.
