    33# This shell script handles all target based configuration for libstdc++.
    44# It sets various shell variables based on the the target and the
    5 # configuration options.  You can modify this shell script without
    6 # needing to rerun autoconf.
    7 
    8 # This shell script should be invoked as
    9 #   . configure.target
    10 # If it encounters an error, it will exit with a message.
    11 
    12 # It uses the following shell variables:
    13 #   target                The configuration target
     5# configuration options.  You can modify this shell script without needing
     6# to rerun autoconf/aclocal/etc.  This file is "sourced" not executed.
     7#
     8# You should read docs/html/17_intro/porting.* to make sense of this file.
     9#
     10#
     11# It uses the following shell variables as set by config.guess:
     12#   target                The configuration target (full CPU-vendor-OS triplet)
    1413#   target_cpu            The configuration target CPU
    1514#   target_os             The configuration target OS
    16 
    17 # It possibly modifies the following shell variables:
    18 #   cpu_include_dir        CPU-specific include directory, relative to srcdir
    19 #
    20 #   os_include_dir         OS-specific include directory, relative to srcdir
     15#
     16#
     17# It sets the following shell variables:
     18#
     19#   cpu_include_dir        CPU-specific directory, defaults to cpu/generic
     20#                          if cpu/target_cpu doesn't exist.  This is
     21#                          used to set ATOMICITYH.
     22#
     23#   os_include_dir         OS-specific directory, defaults to os/generic.
    2124#
    2225#   c_model                the model to use for "C" headers, defaults to c_std.
    2326#
    24 #   c_compatibility        if "C" compatibility headers are necessary,
    25 #                              defaults to no.
     27#   c_compatibility        if "C" compatibility headers are necessary,
     28#                          defaults to no.
     29#
     30#   abi_baseline_pair      directory name for ABI compat testing,
     31#                          defaults to target (as per config.guess)
     32#
     33#   ATOMICITYH             location of atomicity.h,
     34#                          defaults to cpu_include_dir
     35#
     36# It possibly modifies the following variables:
     37#
     38#   OPT_LDFLAGS            extra flags to pass when linking the library, of
     39#                          the form '-Wl,blah'
     40#                          (defaults to empty in acinclude.m4)
     41#
     42#
     43# If the defaults will not work for your platform, you need only change the
     44# variables that won't work, i.e., you do not need to explicitly set a
     45# working variable to its default.  Most targets only need to change the two
     46# *_include_dir variables.
