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.out_file=tmake_file=extra_headers=extra_passes=extra_parts=extra_programs=extra_objs=extra_gcc_objs=c_target_objs=cxx_target_objs=tm_defines=xm_defines=# Set this to force installation and use of collect2.use_collect2=# Set this to override the default target model.target_cpu_default=# Set this if gdb needs a dir command with `dirname $out_file`gdb_needs_out_file_path=# Set this to control which thread package will be used.thread_file=# Reinitialize these from the flag values every loop pass, since some# configure entries modify them.gas="$gas_flag"gnu_ld="$gnu_ld_flag"default_use_cxa_atexit=notarget_gtfiles=need_64bit_hwint=# Default to not using fixproto.
