2001-05-23 Tom Tromey <tromey@redhat.com> * posix-threads.cc (_Jv_self_cache): Renamed from self_cache. * gcj/Makefile.in: Rebuilt. * gcj/Makefile.am (gcj_HEADERS): Added libgcj-config.h. * gcj/javaprims.h: Include gcj/libgcj-config.h. * gcj/libgcj-config.h.in: New file. * libgcj.spec.in (*jc1): Added @HASH_SYNC_SPEC@. * configure: Rebuilt. * configure.in: Enable hash synchronization by default on some platforms. (HASH_SYNC_SPEC): New subst. (AC_CONFIG_HEADER): Added gcj/libgcj-config.h. Correctly use `test -z' instead of `test -n' in a couple places. (JV_HASH_SYNCHRONIZATION): Use AC_DEFINE; don't add to LIBGCJ_CXXFLAGS. * configure.host (enable_java_net_default): Initialize. (enable_hash_synchronization_default): New variable. 2001-05-23 Hans Boehm <Hans_Boehm@hp.com> * boehm.cc (_Jv_MarkObj): Don't mark sync_info when hash synchronization in use. (_Jv_MarkArray): Likewise. (_Jv_AllocBytes): Don't check return result. (handle_out_of_memory): New function. (_Jv_InitGC): Set GC_oom_fn. (trace_one_vtable): New global.

(_Jv_AllocArray): Likewise. (_Jv_AllocBytes): Likewise. (_Jv_AllocPtrFreeObject): New function. (_Jv_AllocTraceOne): Likewise. * posix-threads.cc (_Jv_ThreadRegister): Handle slow pthread_self(). (self_cache): New global. (_Jv_ThreadSelf_out_of_line): New function. * prims.cc (_Jv_AllocBytesChecked): Removed. (_Jv_ThrowNoMemory): New function. (_Jv_AllocObject): Don't check for null return from allocator. (_Jv_NewObjectArray): Likewise. (_Jv_AllocPtrFreeObject): New function. (_Jv_NewPrimArray): Allocate pointer-free object if possible. * include/javaprims.h (_Jv_AllocPtrFreeObject): Declare.

# 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
