# 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 ${host}, and also uses the
# following shell variables:
#
# with_* Various variables as set by configure.
# This file sets the following shell variables for use by the
# autoconf-generated configure script:
#
# asm_hidden_op The assembler pseudo-op to use for hide
# lists for object files implemented in
# assembly (with -fvisibility=hidden for C).
# The default is ".hidden".
# cpu_type The name of the cpu, if different from the first
# chunk of the canonical host name.
# extra_parts List of extra object files that should be compiled
# for this target machine. This may be overridden
# by setting EXTRA_PARTS in a tmake_file fragment.
# If either is set, EXTRA_PARTS and
# EXTRA_MULTILIB_PARTS inherited from the GCC
# subdirectory will be ignored.
# tmake_file A list of machine-description-specific
# makefile-fragments, if different from
# "$cpu_type/t-$cpu_type".
asm_hidden_op=.hidden
extra_parts=
tmake_file=
# Set default cpu_type so it can be updated in each machine entry.
