# 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.
#

#
#  out_file             The name of the machine description C support
#                       file, if different from "$cpu_type/$cpu_type.c".

#  common_out_file      The name of the source file for code shared between
#                       the compiler proper and the driver.
#
#  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)

#                       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.

#
#  gdb_needs_out_file_path
#                       Set to yes if gdb needs a dir command with
