# configure.host
|
|
#
|
|
# This shell script handles all host based configuration for libstdc++.
|
|
# It sets various shell variables based on the the host and the
|
|
# configuration options. You can modify this shell script without needing
|
|
# to rerun autoconf/aclocal/etc. This file is "sourced" not executed.
|
|
#
|
|
# You should read docs/html/17_intro/porting.* to make sense of this file.
|
|
#
|
|
#
|
|
# It uses the following shell variables as set by config.guess:
|
|
# host The configuration host (full CPU-vendor-OS triplet)
|
|
# host_cpu The configuration host CPU
|
|
# host_os The configuration host OS
|
|
#
|
|
#
|
|
# It sets the following shell variables:
|
|
#
|
|
# cpu_include_dir CPU-specific directory, defaults to cpu/generic
|
|
# if cpu/host_cpu doesn't exist. This is not used
|
|
# directly, but sets the default for others.
|
|
#
|
|
# os_include_dir OS-specific directory, defaults to os/generic.
|
|
#
|
|
# c_model the "C" header model, defaults to c_global.
|
|
#
|
|
# c_compatibility if "C" compatibility headers are necessary,
|
|
# defaults to no.
|
|
#
|
|
# abi_baseline_pair directory name for ABI compat testing,
|
|
# defaults to host_cpu-host_os (as per config.guess)
|
|
#
|
|
# abi_baseline_subdir_switch
|
|
# g++ switch to determine ABI baseline subdir for
|
|
# multilibbed targets,
|
|
# defaults to --print-multi-directory
|
|
#
|
|
# abi_tweaks_dir location of cxxabi_tweaks.h,
|
|
# defaults to cpu_include_dir
|
|
#
|
|
# atomicity_dir location of atomicity.h,
|
|
# defaults to cpu_include_dir
|
|
#
|
|
# atomic_word_dir location of atomic_word.h
|
|
# defaults to generic.
|
|
#
|
|
# atomic_flags extra flags to pass to use atomic instructions
|
|
# defaults to nothing.
|
|
#
|
|
# cpu_defines_dir location of cpu_defines.h
|
|
# defaults to generic.
|
|
#
|
|
# cpu_opt_bits_random path name of random.h containing CPU-specific
|
|
# optimizations
|
|
#
|
|
# cpu_opt_ext_random path name of random.h containing CPU-specific
|
|
# optimizations for extensions
|
|
#
|
|
# error_constants_dir location of error_constants.h
|
|
# defaults to os/generic.
|
|
#
|
|
# It possibly modifies the following variables:
|
|
#
|
|
# OPT_LDFLAGS extra flags to pass when linking the library, of
|
|
# the form '-Wl,blah'
|
|
# (defaults to empty in acinclude.m4)
|
|
#
|
|
# port_specific_symbol_files
|
|
# whitespace-seperated list of files containing
|
|
# additional symbols to export from the shared
|
|
# library, when symbol versioning is in use
|
|
#
|
|
#
|
|
# If the defaults will not work for your platform, you need only change the
|
|
# variables that won't work, i.e., you do not need to explicitly set a
|
|
# working variable to its default. Most hosts only need to change the two
|
|
# *_include_dir variables.
|
|
|
|
|
|
# DEFAULTS
|
|
# Try to guess a default cpu_include_dir based on the name of the CPU. We
