Note: This is a cumulative patch containing the work of several people
which is impossible to separate now.
This patch contains a number of '#ifdef 0'-like hacks that need to be
reviewed and fixed properly as they are unlikely to be accepted upstream
in the current form. Also, some patches may be not relevant any more.

# This is the GCC 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 switches on the shell variable ${host}. As much of this as
|
|
# is reasonable should be replaced with autoconf tests in the future.
|
|
|
|
# This file sets the following shell variables for use by the
|
|
# autoconf-generated configure script:
|
|
#
|
|
# host_xm_file List of files to include when compiling for the
|
|
# host machine.
|
|
#
|
|
# host_xm_defines List of macros to define when compiling for the
|
|
# host machine.
|
|
#
|
|
# host_xmake_file List of host-specific makefile-fragments.
|
|
#
|
|
# host_exeext Set to the suffix, if the host machine requires
|
|
# executables to have a file name suffix.
|
|
#
|
|
# host_extra_objs List of extra host-dependent objects that should
|
|
# be linked into the compiler proper.
|
|
#
|
|
# host_extra_gcc_objs List of extra host-dependent objects that should
|
|
# be linked into the gcc driver.
|
|
#
|
|
# out_host_hook_obj An object file that provides the host hooks.
|
|
#
|
|
# host_can_use_collect2 Set to yes normally; to no if the host cannot
|
|
# link or otherwise use collect2
|
|
#
|
|
# use_long_long_for_widest_fast_int Set this to 'yes' if 'long long'
|
|
# (or '__int64') is wider than 'long' but still
|
|
# efficeiently supported by the host hardware.
|
|
# Only affects compile speed. Default is 'no'.
|
|
#
|
|
# host_lto_plugin_soname Set this to the name to which the LTO linker
|
|
# plugin gets compiled on this host, if it is
|
|
# different from the default "liblto_plugin.so".
|
|
|
|
# When setting any of these variables, check to see if a corresponding
|
|
# variable is present in config.build; if so, you will likely want to
|
|
# set it in both places.
|
|
|
|
# Default settings.
