Have -fnew-exceptions actually use the runtime field, and not generate runtime checking code inside each handler. THis works at low opt, but not with optimization at the moment. Tue Jun 23 10:06:07 EDT 1998 Andrew MacLeod (amacleod@cygnus.com) * eh-common.h (struct __eh_info): Remove coerced value field. * libgcc2.c (find_exception_handler): Don't set coerced_value field. * except.c (get_dynamic_handler_chain, get_dynamic_cleanup_chain): Use POINTER_SIZE instead of Pmode. (expand_start_all_catch): Call start_catch_handler() if we are not using new style exceptions. 1998-06-22 Andrew MacLeod (amacleod@cygnus.com) * parse.y (function_try_block): Don't call start_catch_handler. * except.c (call_eh_info): Remove coerced field from declaration. (build_eh_type_type_ref): New function to create an address of a rtti function for the new style exception tables. (expand_start_catch_block): Split function, this contains the common part. (process_start_catch_block_old): New function to perform the rest of expand_start_catch_block under old style exceptions. (process_start_catch_block_old): New function to perform the rest of expand_start_catch_block under new style exceptions. (expand_end_catch_block): Only pop the false label off the stack under the old style of exceptions. * semantics.c (finish_try_block): Don't call start_catch_handler. * exception.cc (struct cp_eh_info): Add original_value field. (__cplus_type_matcher): Perform type matching on the original exception value, and if we have a match, set the current value. (__cp_push_exception): Set the original expcetion value.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
