# This is the libgcc host-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 host-specific information.

# This file bears an obvious resemblance to gcc/config.gcc.  The cases
# should be kept similar, to ease moving library-specific settings
# from config.gcc to this file.  That is also why tmake_file is
# left as tmake_file, rather than hmake_file, even though this library
# switches on ${host}.

# This file switches on the shell variable ${host}, and also uses the
# following shell variables:
#
#  with_*               Various variables as set by configure.

# This file sets the following shell variables for use by the
# autoconf-generated configure script:
#
#  asm_hidden_op        The assembler pseudo-op to use for hide
#                       lists for object files implemented in
#                       assembly (with -fvisibility=hidden for C).
#                       The default is ".hidden".
#  cpu_type             The name of the cpu, if different from the first
#                       chunk of the canonical host name.
#  enable_execute_stack The name of a source file implementing
#                       __enable_execute_stack.
#  extra_parts          List of extra object files that should be compiled
#                       for this target machine.  This may be overridden
#                       by setting EXTRA_PARTS in a tmake_file fragment.
#                       If either is set, EXTRA_PARTS and
#                       EXTRA_MULTILIB_PARTS inherited from the GCC
#                       subdirectory will be ignored.
#  md_unwind_header     The name of a header file defining
#                       MD_FALLBACK_FRAME_STATE_FOR.
#  sfp_machine_header   The name of a sfp-machine.h header file for soft-fp.
#                       Defaults to "$cpu_type/sfp-machine.h" if it exists,
#                       no-sfp-machine.h otherwise.
#  tmake_file           A list of machine-description-specific
#                       makefile fragments.
#  tm_defines           List of target macros to define for all compilations.
#  tm_file              A list of target macro files used only for code
#                       built for the target, not the host.  These files
#                       are relative to $srcdir/config and must not have
#                       the same names as files in $srcdir/../gcc/config.
#  unwind_header        The name of the header file declaring the unwind
#                       runtime interface routines.
