   3 # This shell script handles all target based configuration for libstdc++.
   4 # 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
  14 #   target_cpu            The configuration target CPU
  15 #   target_os             The configuration target OS
  16 #   target_optspace       --enable-target-optspace ("yes", "no", "")
  17
  18 # It possibly modifies the following shell variables:
  19 #   glibcpp_cflags         Special CFLAGS to use when building
  20 #   glibcpp_cxxflags       Special CXXFLAGS to use when building
  21 #   cpu_include_dir        CPU-specific include directory, relative to srcdir
  22 #   os_include_dir         OS-specific include directory, relative to srcdir
  23 # The first two are set in configure.host and modified here.
  24

  27 # will be appended to their real conterparts once the dust settles.
