This is invoked by the autoconf-generated 23# configure script. Putting it in a separate shell file lets us skip 24# running autoconf when modifying host-specific information. 25 26# This file switches on the shell variable ${host}. As much of this as 27# is reasonable should be replaced with autoconf tests in the future. 28 29# This file sets the following shell variables for use by the 30# autoconf-generated configure script: 31# 32# host_xm_file List of files to include when compiling for the 33# host machine. 34# 35# host_xm_defines List of macros to define when compiling for the 36# host machine. 37# 38# host_xmake_file List of host-specific makefile-fragments. 39# 40# host_exeext Set to the suffix, if the host machine requires 41# executables to have a file name suffix. 42# 43# host_extra_objs List of extra host-dependent objects that should 44# be linked into the compiler proper. 45# 46# host_extra_gcc_objs List of extra host-dependent objects that should 47# be linked into the gcc driver. 48# 49# out_host_hook_obj An object file that provides the host hooks. 50# 51# host_can_use_collect2 Set to yes normally; to no if the host cannot 52# link or otherwise use collect2 53# 54# use_long_long_for_widest_fast_int Set this to 'yes' if 'long long' 55# (or '__int64') is wider than 'long' but still 56# efficeiently supported by the host hardware. 57# Only affects compile speed. Default is 'no'. 58# 59# host_lto_plugin_soname Set this to the name to which the LTO linker 60# plugin gets compiled on this host, if it is 61# different from the default "liblto_plugin.so". 62 63# When setting any of these variables, check to see if a corresponding 64# variable is present in config.build; if so, you will likely want to 65# set it in both places. 66 67# Default settings. 68host_xm_file= 69host_xm_defines= 70host_xmake_file= 71host_exeext= 72host_extra_objs= 73host_extra_gcc_objs= 74out_host_hook_obj=host-default.o 75host_can_use_collect2=yes 76use_long_long_for_widest_fast_int=no 77host_lto_plugin_soname=liblto_plugin.so 78 79# Unsupported hosts list.
