The first non-flag argument is always +a program to debug, but the second non-flag argument may either +be a corefile or a process id. Previously, GDB would attempt to +open the second argument as a corefile, and if that failed, would +issue a superfluous error message and then attempt to attach it as +a process. Now, if the second argument begins with a non-digit, +it will be treated as a corefile. If it begins with a digit, +GDB will attempt to attach it as a process, and if no such process +is found, will then attempt to open it as a corefile. + +* New native configurations + +x86 OpenBSD i[3456]86-*-openbsd* + +* New targets + +Sanyo XStormy16 xstormy16-elf + +* OBSOLETE configurations and files + +Configurations that have been declared obsolete in this release have +been commented out.

In particular, the +sources are fully protoized, and rely on standard headers being +present. * Other news: -* All MIPS configurations are multi-arched. +* "info symbol" works on platforms which use COFF, ECOFF, XCOFF, and NLM. + +* The MI enabled by default. + +The new machine oriented interface (MI) introduced in GDB 5.0 has been +revised and enabled by default. Packages which use GDB as a debugging +engine behind a UI or another front end are encouraged to switch to +using the GDB/MI interface, instead of the old annotations interface +which is now deprecated. + +* Support for debugging Pascal programs. + +GDB now includes support for debugging Pascal programs. The following +main features are supported: + + - Pascal-specific data types such as sets; + + - automatic recognition of Pascal sources based on file-name + extension; + + - Pascal-style display of data types, variables, and functions; + + - a Pascal expression parser. + +However, some important features are not yet supported. + + - Pascal string operations are not supported at all; + + - there are some problems with boolean types; + + - Pascal type hexadecimal constants are not supported + because they conflict with the internal variables format; + + - support for Pascal objects and classes is not full yet; + + - unlike Pascal, GDB is case-sensitive for symbol names. + +* Changes in completion. + +Commands such as `shell', `run' and `set args', which pass arguments +to inferior programs, now complete on file names, similar to what +users expect at the shell prompt. + +Commands which accept locations, such as `disassemble', `print', +`breakpoint', `until', etc. now complete on filenames as well as +program symbols. Thus, if you type "break foob TAB", and the source +files linked into the programs include `foobar.c', that file name will +be one of the candidates for completion. However, file names are not +considered for completion after you typed a colon that delimits a file +name from a name of a function in that file, as in "break foo.c:bar". + +`set demangle-style' completes on available demangling styles. + +* New platform-independent commands: + +It is now possible to define a post-hook for a command as well as a +hook that runs before the command. For more details, see the +documentation of `hookpost' in the GDB manual. + +* Changes in GNU/Linux native debugging. + +Support for debugging multi-threaded programs has been completely +revised for all platforms except m68k and sparc. You can now debug as +many threads as your system allows you to have. + +Attach/detach is supported for multi-threaded programs. + +Support for SSE registers was added for x86. This doesn't work for +multi-threaded programs though. + +* Changes in MIPS configurations. Multi-arch support is enabled for all MIPS configurations. +GDB can now be built as native debugger on SGI Irix 6.x systems for +debugging n32 executables. (Debugging 64-bit executables is not yet +supported.) + +* Unified support for hardware watchpoints in all x86 configurations. + +Most (if not all) native x86 configurations support hardware-assisted +breakpoints and watchpoints in a unified manner. This support +implements debug register sharing between watchpoints, which allows to +put a virtually infinite number of watchpoints on the same address, +and also supports watching regions up to 16 bytes with several debug +registers. + +The new maintenance command `maintenance show-debug-regs' toggles +debugging print-outs in functions that insert, remove, and test +watchpoints and hardware breakpoints. + +* Changes in the DJGPP native configuration. + +New command ``info dos sysinfo'' displays assorted information about +the CPU, OS, memory, and DPMI server. + +New commands ``info dos gdt'', ``info dos ldt'', and ``info dos idt'' +display information about segment descriptors stored in GDT, LDT, and +IDT. + +New commands ``info dos pde'' and ``info dos pte'' display entries +from Page Directory and Page Tables (for now works with CWSDPMI only). +New command ``info dos address-pte'' displays the Page Table entry for +a given linear address. + +GDB can now pass command lines longer than 126 characters to the +program being debugged (requires an update to the libdbg.a library +which is part of the DJGPP development kit). + +DWARF2 debug info is now supported. + +It is now possible to `step' and `next' through calls to `longjmp'. + +* Changes in documentation. + +All GDB documentation was converted to GFDL, the GNU Free +Documentation License. + +Tracepoints-related commands are now fully documented in the GDB +manual. + +TUI, the Text-mode User Interface, is now documented in the manual. + +Tracepoints-related commands are now fully documented in the GDB +manual. + +The "GDB Internals" manual now has an index. It also includes +documentation of `ui_out' functions, GDB coding standards, x86 +hardware watchpoints, and memory region attributes. + +* GDB's version number moved to ``version.in'' + +The Makefile variable VERSION has been replaced by the file +``version.in''. People creating GDB distributions should update the +contents of this file. + * gdba.el deleted GUD support is now a standard part of the EMACS distribution.
