   1 # configure.host

   3 # This shell script handles all host based configuration for libgcj.
   4 # It sets various shell variables based on the the host 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.host
  10 # If it encounters an error, it will exit with a message.
  11
  12 # It uses the following shell variables:
  13 #   host                The configuration host
  14 #   host_cpu            The configuration host CPU
  15 #   target_optspace     --enable-target-optspace ("yes", "no", "")
  16
  17 # It sets the following shell variables:
  18 #   libgcj_cflags       Special CFLAGS to use when building
  19 #   libgcj_cxxflags     Special CXXFLAGS to use when building
  20 #   libgcj_javaflags    Special JAVAFLAGS to use when building
  21 #   libgcj_interpreter  If the bytecode interpreter supports this platform.
  22 #   enable_java_net_default  If java.net native code should be enabled by
  23 #                            default.
  24 #   enable_hash_synchronization_default  If hash synchronization should be
  25 #                                        enabled by default.
  26 #   sysdeps_dir         Directory containing system-dependent headers
  27 #   slow_pthread_self   The synchronization code should try to avoid
  28 #                       pthread_self calls by caching thread IDs in a hashtable
