This is invoked by the autoconf-generated 25# configure script. Putting it in a separate shell file lets us skip 26# running autoconf when modifying host-specific information. 27 28# This file switches on the shell variable ${host}. As much of this as 29# is reasonable should be replaced with autoconf tests in the future. 30 31# This file sets the following shell variables for use by the 32# autoconf-generated configure script: 33# 34# host_xm_file List of files to include when compiling for the 35# host machine. 36# 37# host_xm_defines List of macros to define when compiling for the 38# host machine. 39# 40# host_xmake_file List of host-specific makefile-fragments. 41# 42# host_exeext Set to the suffix, if the host machine requires 43# executables to have a file name suffix. 44# 45# host_extra_objs List of extra host-dependent objects that should 46# be linked into the compiler proper. 47# 48# host_extra_gcc_objs List of extra host-dependent objects that should 49# be linked into the gcc driver. 50# 51# out_host_hook_obj An object file that provides the host hooks. 52# 53# host_can_use_collect2 Set to yes normally; to no if the host cannot 54# link or otherwise use collect2 55# use_long_long_for_widest_fast_int Set this to 'yes' if 'long long' 56# (or '__int64') is wider than 'long' but still 57# efficeiently supported by the host hardware. 58# Only affects compile speed. Default is 'no'. 59 60# When setting any of these variables, check to see if a corresponding 61# variable is present in config.build; if so, you will likely want to 62# set it in both places. 63 64# Default settings. 65host_xm_file= 66host_xm_defines= 67host_xmake_file= 68host_exeext= 69host_extra_objs= 70host_extra_gcc_objs= 71out_host_hook_obj=host-default.o 72host_can_use_collect2=yes 73use_long_long_for_widest_fast_int=no 74 75# Unsupported hosts list.
