Release 6.7 of GDB, the GNU Debugger, is now available via anonymous FTP. GDB is a source-level debugger for Ada, C, C++, Objective-C, Pascal and many other languages. GDB can target (i.e., debug programs running on) more than a dozen different processor architectures, and GDB itself can run on most popular GNU/Linux, Unix and Microsoft Windows variants. You can download GDB from the GNU FTP server in the directory: ftp://ftp.gnu.org/gnu/gdb The vital stats: Size md5sum Name 15MB d6e7c0ad7654bc91a3a457fabb6ad6c6 gdb-6.7.tar.bz2 20MB 5f415f8bef0f3a4947845c78ab102b2d gdb-6.7.tar.gz There is a web page for GDB at: http://www.gnu.org/software/gdb/ That page includes information about GDB mailing lists (an announcement mailing list, developers discussion lists, etc.), details on how to access GDB's CVS repository, locations for development snapshots, preformatted documentation, and links to related information around the net. We will put errata notes and host-specific tips for this release on-line as any problems come up. All mailing lists archives are also browsable via the web. Since the previous release (6.5, released in December 2006) we have made many fixes and enhancements including: * Resolved 101 resource leaks, null pointer dereferences, etc. in gdb, bfd, libiberty and opcodes, as revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). * When looking up multiply-defined global symbols, GDB will now prefer the symbol definition in the current shared library if it was built using the -Bsymbolic linker option. * When the Text User Interface (TUI) is not configured, GDB will now recognize the -tui command-line option and print a message that the TUI is not supported. * The GDB remote stub, gdbserver, now has lower overhead for high frequency signals (e.g. SIGALRM) via the QPassSignals packet. * GDB for MIPS targets now autodetects whether a remote target provides 32-bit or 64-bit register values. * Support for C++ member pointers has been improved. * GDB now understands XML target descriptions, which specify the target's overall architecture. GDB can read a description from a local file or over the remote serial protocol. * Vectors of single-byte data use a new integer type which is not automatically displayed as character or string data. * The /s format now works with the print command. It displays arrays of single-byte integers and pointers to single-byte integers as strings. * Target descriptions can now describe target-specific registers, for architectures which have implemented the support (currently only ARM, M68K, and MIPS). * GDB and the GDB remote stub, gdbserver, now support the XScale iWMMXt coprocessor. * The GDB remote stub, gdbserver, has been updated to support ARM Windows CE (mingw32ce) debugging, and GDB Windows CE support has been rewritten to use the standard GDB remote protocol. * GDB can now step into C++ functions which are called through thunks. * GDB for the Cell/B.E. SPU now supports overlay debugging. * The GDB remote protocol "qOffsets" packet can now honor ELF segment layout. It also supports a TextSeg= and DataSeg= response when only segment base addresses (rather than offsets) are available. * The /i format now outputs any trailing branch delay slot instructions immediately following the last instruction within the count specified. * The GDB remote protocol "T" stop reply packet now supports a "library" response. Combined with the new "qXfer:libraries:read" packet, this response allows GDB to debug shared libraries on targets where the operating system manages the list of loaded libraries (e.g. Windows and SymbianOS). * The GDB remote stub, gdbserver, now supports dynamic link libraries (DLLs) on Windows and Windows CE targets. * GDB now supports a faster verification that a .debug file matches its binary according to its build-id signature, if the signature is present. The following new commands have been added: set remoteflow show remoteflow Enable or disable hardware flow control (RTS/CTS) on the serial port when debugging using remote targets. set mem inaccessible-by-default show mem inaccessible-by-default If the target supplies a memory map, for instance via the remote protocol's "qXfer:memory-map:read" packet, setting this variable prevents GDB from accessing memory outside the memory map. This is useful for targets with memory mapped registers or which react badly to accesses of unmapped address space. set breakpoint auto-hw show breakpoint auto-hw If the target supplies a memory map, for instance via the remote protocol's "qXfer:memory-map:read" packet, setting this variable lets GDB use hardware breakpoints automatically for memory regions where it can not use software breakpoints. This covers both the "break" command and internal breakpoints used for other commands including "next" and "finish". catch exception catch exception unhandled Stop the program execution when Ada exceptions are raised. catch assert Stop the program execution when an Ada assertion failed. set sysroot show sysroot Set an alternate system root for target files. This is a more general version of "set solib-absolute-prefix", which is now an alias to "set sysroot". info spu Provide extended SPU facility status information. This set of commands is available only when debugging the Cell/B.E. SPU architecture. set tdesc filename unset tdesc filename show tdesc filename Use the specified local file as an XML target description, and do not query the target for its built-in description. Support for some new native configuration have been added: OpenBSD/sh sh*-*openbsd* Support for the following targets has been added: OpenBSD/sh sh*-*-openbsd* MIPS64 GNU/Linux (gdbserver) mips64-linux-gnu Toshiba Media Processor mep-elf The following new remote packets have been introduced: QPassSignals: Ignore the specified signals; pass them directly to the debugged program without stopping other threads or reporting them to GDB. qXfer:features:read: Read an XML target description from the target, which describes its features. qXfer:spu:read: qXfer:spu:write: Read or write contents of an spufs file on the target system. These qXfer:libraries:read: Report the loaded shared libraries. Combined with new "T" packet response, this packet allows GDB to debug shared libraries on targets where the operating system manages the list of loaded libraries (e.g. Windows and SymbianOS). Support for these obsolete configurations has been removed: alpha*-*-osf1* alpha*-*-osf2* d10v-*-* hppa*-*-hiux* i[34567]86-ncr-* i[34567]86-*-dgux* i[34567]86-*-lynxos* i[34567]86-*-netware* i[34567]86-*-sco3.2v5* i[34567]86-*-sco3.2v4* i[34567]86-*-sco* i[34567]86-*-sysv4.2* i[34567]86-*-sysv4* i[34567]86-*-sysv5* i[34567]86-*-unixware2* i[34567]86-*-unixware* i[34567]86-*-sysv* i[34567]86-*-isc* m68*-cisco*-* m68*-tandem-* mips*-*-pe rs6000-*-lynxos* sh*-*-pe Some other removed features: target abug target cpu32bug target est target rom68k Various m68k-only ROM monitors. target hms target e7000 target sh3 target sh3e Various Renesas ROM monitors and debugging interfaces for SH and H8/300. target ocd Support for a Macraigor serial interface to on-chip debugging. GDB does not directly support the newer parallel or USB interfaces. DWARF 1 support A debug information format. The predecessor to DWARF 2 and DWARF 3, which are still supported. Support for the HP aCC compiler on HP-UX/PA-RISC SOM-encapsulated symbolic debugging information, automatic invocation of pxdb, and the aCC custom C++ ABI. This does not affect HP-UX for Itanium or GCC for HP-UX/PA-RISC. Code compiled with aCC can still be debugged on an assembly level. MIPS ".pdr" sections A MIPS-specific format used to describe stack frame layout in debugging information. Scheme support GDB could work with an older version of Guile to debug the interpreter and Scheme programs running in it. set mips stack-arg-size set mips saved-gpreg-size Use "set mips abi" to control parameter passing for MIPS.
