# 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.
|
|
# tmake_file A list of machine-description-specific
