# 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.

#

#  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}.

#

#                       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}.

#

#  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.

#                       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

#                       `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.
