# 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
#			  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.
#
#  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
# LLVM LOCAL
#			in $out_file & $out_cxx_file
#
#  out_file		The name of the machine description C support
#			file, if different from "$cpu_type/$cpu_type.c".
# LLVM LOCAL
#  out_cxx_file		The name of the machine description C++ support file.
#
#  md_file		The name of the machine-description file, if
#			different from "$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.
#
#  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.
#
#  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.
