gdb/gdb-6.3-large-core-20051206.patch
Jan Kratochvil e3c8b47c74 - Remove `gdb-6.3-nonthreaded-wp-20050117.patch' as obsoleted + regressing 
now.
- Make the GDB quit processing non-abortable to cleanup everything
    properly.
- Support DW_TAG_constant for Fortran in recent Fedora/RH GCCs.
- Fix crash on DW_TAG_module for Fortran in recent Fedora/RH GCCs.
- Readd resolving of bare names of constructors and destructors.
- Include various vendor testcases:
- Leftover zombie process (BZ 243845).
- Multithreaded watchpoints (`gdb.threads/watchthreads2.exp').
- PIE testcases (`gdb.pie/*').
- C++ contructors/destructors (`gdb.cp/constructortest.exp').

* symfile-mem.c (read_memory): New static read callback function.
(symfile_add_from_memory): Pass read_memory to bfd instead of
target_read_memory.
* target.c (target_xfer_memory): Add support for LONGEST len and
change all callers.
(deprecated_debug_xfer_memory, target_read_memory): Ditto.
(target_write_memory, do_xfer_memory): Ditto.
(target_xfer_memory_partial, target_read_memory_partial): Ditto.
(target_write_memory_partial): Ditto.
* infptrace.c (child_xfer_memory): Ditto.
* linux-nat.c (linux_nat_xfer_memory): Ditto.
(linux_nat_proc_xfer_memory): Ditto.
* dcache.c (dcache_xfer_memory): Ditto.
* exec.c (xfer_memory): Ditto.
* remote.c (remote_xfer_memory): Ditto.
* remote-sim.c (gdbsim_xfer_interior_memory): Ditto.
* target.h: Change prototypes for functions changed above.
* linux-nat.h: Ditto.
* remote.h: Ditto.
* dcache.h: Ditto.
