GDB 7.8.1 released!

Joel Brobecker


            GDB 7.8.1 released!

Release 7.8.1 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
  17MiB  997492cc3475c96f35ecc8775248c9b1  gdb-7.8.1.tar.xz
  32MiB  8072be87a94be0936bc3b4b6941b0862  gdb-7.8.1.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 source 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.

GDB 7.8 brings new targets, features and improvements, including:

  * Guile scripting support.

  * Python scripting enhancements.

  * New commands:

    ** guile
    ** guile-repl
    ** info auto-load guile-scripts [REGEXP]

  * New options:

    ** maint ada set ignore-descriptive-types (on|off)
    ** maint set target-async (on|off)
    ** set|show auto-load guile-scripts (on|off)
    ** set|show auto-connect-native-target
    ** set|show guile print-stack (none|message|full)
    ** set|show mi-async (on|off)
    ** set|show print symbol-loading (off|brief|full)
    ** set|show record btrace replay-memory-access (read-only|read-write)

  * Deprecated commands:

    ** "dll-symbols" and its two aliases ("add-shared-symbol-files" and
       "assf"). Use the "sharedlibrary" command instead.
    ** "set|show remotebaud". Use "set|show serial baud" instead.

  * Remote Protocol:

    ** The qXfer:btrace:read packet supports a new annex 'delta'.

  * GDB/MI:

    ** A new option "-gdb-set mi-async" replaces "-gdb-set target-async".

  * New target configurations:

    ** PowerPC64 GNU/Linux little-endian       powerpc64le-*-linux*

 * btrace enhancements:

    ** The btrace record target now supports the 'record goto' command.
    ** The btrace record target supports limited reverse execution and
       replay.

 * ISO C99 variable length automatic arrays support.

 * It is no longer required to "set target-async on" in order to use
   background execution commands (e.g., "c&", "s&", etc.).

 * "catch syscall" now implemented on s390*-linux* targets.

 * The "compare-sections" command now works on all targets.

 * The "target native" command now connects to the native target, and
   can be used to launch native programs, even if "set
   auto-connect-native-target" is set to off.
