* configure.host: Set can_unwind_signal on hosts which support it. Don't set CHECKREFSPEC and DIVIDESPEC for FreeBSD. * configure.in: Set CHECKREFSPEC and DIVIDESPEC if not using SJLJ exceptions and can_unwind_signal isn't set. * configure: Rebuilt. From-SVN: r52193

# configure.host
|
|
|
|
# This shell script handles all host based configuration for libgcj.
|
|
# 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.
|
|
|
|
# This shell script should be invoked as
|
|
# . configure.host
|
|
# If it encounters an error, it will exit with a message.
|
|
|
|
# It uses the following shell variables:
|
|
# host The configuration host
|
|
# host_cpu The configuration host CPU
|
|
# target_optspace --enable-target-optspace ("yes", "no", "")
|
|
|
|
# It sets the following shell variables:
|
|
# libgcj_cflags Special CFLAGS to use when building
|
|
# libgcj_cxxflags Special CXXFLAGS to use when building
|
|
# libgcj_javaflags Special JAVAFLAGS to use when building
|
|
# libgcj_interpreter If the bytecode interpreter supports this platform.
|
|
# enable_java_net_default If java.net native code should be enabled by
|
|
# default.
|
|
# enable_hash_synchronization_default If hash synchronization should be
|
|
# enabled by default.
|
|
# sysdeps_dir Directory containing system-dependent headers
|
|
# slow_pthread_self The synchronization code should try to avoid
|
|
# pthread_self calls by caching thread IDs in a hashtable
|
|
# can_unwind_signal Set to "yes" if the EH unwinder supports throwing
|
|
# from a signal handler.
