libjava/ChangeLog
1999-11-19 Tom Tromey <tromey@cygnus.com>
* Makefile.am (DIVIDESPEC): Removed.
(EXCEPTIONSPEC): Removed.
1999-11-19 Andrew Haley <aph@cygnus.com>
* Makefile.am (JCFLAGS): Add -L$(here)
(JC1FLAGS): Ditto.
* Makefile.in: Rebuild.
1999-11-18 Tom Tromey <tromey@cygnus.com>
* java/lang/natDouble.cc: Include <config.h>.
* include/config.h.in: Rebuilt.
* acconfig.h (SJLJ_EXCEPTIONS): Undefine.
* configure.host: Force -fsjlj-exceptions on non-sparc, non-x86
targets.
* configure: Rebuilt.
* configure.in (EXCEPTIONSPEC): Allow -fsjlj-exceptions to be
requested by configure.host. Don't put `-D' option into
libgcj.spec; instead, define SJLJ_EXCEPTIONS with AC_DEFINE.

* configure.in (EXCEPTIONSPEC): Changed `_' to `-' in
sjlj-exceptions.
1999-11-18 Andrew Haley <aph@cygnus.com>
* Makefile.am: rename SJLJ_EXCEPTIONS to EXCEPTIONSPEC.
(AM_CFLAGS): remove SJLJ_EXCEPTIONS.
(JC1FLAGS): Ditto.
* Makefile.in: Rebuild

Do not AC_DEFINE SJLJ_EXCEPTIONS.
* libgcj.spec.in: Add EXCEPTIONSPEC to jc1.
* gcj/Makefile.in, include/Makefile.in: rebuild.
* include/config.h.in: remove SJLJ_EXCEPTIONS.
1999-11-18 Andrew Haley <aph@cygnus.com>
* gij.cc (main): Rename label to prevent conflict.
* exception.cc (_Jv_type_matcher): Don't check the table if we're
using setjmp/longjmp exceptions: there isn't one.
1999-11-17 Andrew Haley <aph@cygnus.com>
* exception.cc (_Jv_type_matcher): Ignore null exception tables.
(_Jv_Throw ): Add SJLJ_EXCEPTIONS.
(__sjthrow): Add declaration.

* gcj/cni.h: Add support for sjlj-exceptions.
* gcj/javaprims.h: Add _Jv_Sjlj_Throw.
* include/Makefile.in: Rebuild.
* include/default-signal.h: Add support for sjlj-exceptions.
