* New machines supported (target)
AMD 29000 embedded, using EBMON a29k-none-none
* C++ stuff
* C++ support
Improvements have been made in the way GDB handles C++ references. The
demangler has also been improved, and now deals with symbols mangled as
per the Annotated C++ Reference Guide. GDB also now handles stabs embedded in
MIPS symbol tables (which was the only way to get C++ debugging info into MIPS
binaries). This will become useful in a future version of G++.
GDB continues to improve its handling of C++. `References' work better.
The demangler has also been improved, and now deals with symbols mangled as
per the Annotated C++ Reference Guide.
GDB also now handles `stabs' symbol information embedded in MIPS
`ecoff' symbol tables. Since the ecoff format was not easily
extensible to handle new languages such as C++, this appeared to be a
good way to put C++ debugging info into MIPS binaries. This option
will be supported in the GNU C compiler, version 2, when it is
released.
* New features for SVR4
The `info process' command will print out process information.
GDB now handles SVR4 shared libraries, in the same fashion as SunOS
shared libraries. Debugging dynamically linked programs should present
only minor differences from debugging statically linked programs.
Better shared library support for SVR4 and SunOS.
The `info proc' command will print out information about any process
on an SVR4 system (including the one you are debugging). At the moment,
it prints the address mappings of the process.
Info proc, improved SVR4, shared libs
If you bring up GDB on another SVR4 system, please send mail to
bug-gdb@prep.ai.mit.edu to let us know what changes were reqired (if any).
* Better dynamic linking support in SunOS
***FIXME * Improved ELF and DWARF support
GDB can read ELF object files on System V Release 4, and can handle
debugging records for C, in DWARF format, in ELF files. This support
is preliminary. If you bring up GDB on another SVR4 system, please
send mail to bug-gdb@prep.ai.mit.edu to let us know what changes were
reqired (if any).
Reading symbols from shared libraries which contain debugging symbols
now works properly. However, there remain issues such as automatic
skipping of `transfer vector' code during function calls, which
make it harder to debug code in a shared library, than to debug the
same code linked statically.
* New Getopt
GDB is now using the latest `getopt' routines from the FSF. This version
now accepts the -- prefix for options with long names. Note that gdb will
continue to accept the old format as well. Also, various single letter
abbreviations for options have been explicity added to the option table so that
they won't get overshadowed in the future by other options that begin with the
same letter.

GDB now handles cross debugging. If you are remotely debugging between
two different machines, type ``./configure host -target=targ''.
