# 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.
