What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 6.6
+*** Changes since GDB 6.8
+
+* GDB now supports multiple function calling conventions according to the
+ DWARF-2 DW_AT_calling_convention function attribute.
+
+* The SH target utilizes the aforementioned change to distinguish between gcc
+ and Renesas calling convention. It also adds the new CLI commands
+ `set/show sh calling-convention'.
+
+* GDB can now read compressed debug sections, as produced by GNU gold
+with the --compress-debug-sections=zlib flag.
+
+* 64-bit core files are now supported on AIX.
+
+* Watchpoints can now be set on unreadable memory locations, e.g. addresses
+which will be allocated using malloc later in program execution.
+
+* The qXfer:libraries:read remote procotol packet now allows passing a
+list of section offsets.
+
+* New features in the GDB remote stub, gdbserver
+
+ - The "--wrapper" command-line argument tells gdbserver to use a
+ wrapper program to launch programs for debugging.
+
+* New commands
+
+set debug timetstamp
+show debug timestamp
+ Display timestamps with GDB debugging output.
+
+set exec-wrapper
+show exec-wrapper
+unset exec-wrapper
+ Use a wrapper program to launch programs for debugging.
+
+set multiple-symbols (all|ask|cancel)
+show multiple-symbols
+ The value of this variable can be changed to adjust the debugger behavior
+ when an expression or a breakpoint location contains an ambiguous symbol
+ name (an overloaded function name, for instance).
+
+set breakpoint always-inserted
+show breakpoint always-inserted
+ Keep breakpoints always inserted in the target, as opposed to inserting
+ them when resuming the target, and removing them when the target stops.
+ This option can improve debugger performance on slow remote targets.
+
+*** Changes in GDB 6.8
+
+* New native configurations
+
+NetBSD/hppa hppa*-*netbsd*
+Xtensa GNU/Linux xtensa*-*-linux*
+
+* New targets
+
+NetBSD/hppa hppa*-*-netbsd*
+Xtensa GNU/Lunux xtensa*-*-linux*
+
+* Change in command line behavior -- corefiles vs. process ids.
+
+ When the '-p NUMBER' or '--pid NUMBER' options are used, and
+ attaching to process NUMBER fails, GDB no longer attempts to open a
+ core file named NUMBER. Attaching to a program using the -c option
+ is no longer supported. Instead, use the '-p' or '--pid' options.
+
+* GDB can now be built as a native debugger for debugging Windows x86
+(mingw32) Portable Executable (PE) programs.
+
+* Pending breakpoints no longer change their number when their address
+is resolved.
+
+* GDB now supports breakpoints with multiple locations,
+including breakpoints on C++ constructors, inside C++ templates,
+and in inlined functions.
+
+* GDB's ability to debug optimized code has been improved. GDB more
+accurately identifies function bodies and lexical blocks that occupy
+more than one contiguous range of addresses.
+
+* Target descriptions can now describe registers for PowerPC.
+
+* The GDB remote stub, gdbserver, now supports the AltiVec and SPE
+registers on PowerPC targets.
+
+* The GDB remote stub, gdbserver, now supports thread debugging on GNU/Linux
+targets even when the libthread_db library is not available.
+
+* The GDB remote stub, gdbserver, now supports the new file transfer
+commands (remote put, remote get, and remote delete).
+
+* The GDB remote stub, gdbserver, now supports run and attach in
+extended-remote mode.
+
+* hppa*64*-*-hpux11* target broken
+ The debugger is unable to start a program and fails with the following
+ error: "Error trying to get information about dynamic linker".
+ The gdb-6.7 release is also affected.
+
+* GDB now supports the --enable-targets= configure option to allow
+building a single GDB executable that supports multiple remote
+target architectures.
+
+* GDB now supports debugging C and C++ programs which use the
+Decimal Floating Point extension. In addition, the PowerPC target
+now has a set of pseudo-registers to inspect decimal float values
+stored in two consecutive float registers.
+
+* The -break-insert MI command can optionally create pending
+breakpoints now.
+
+* Improved support for debugging Ada
+ Many improvements to the Ada language support have been made. These
+ include:
+ - Better support for Ada2005 interface types
+ - Improved handling of arrays and slices in general
+ - Better support for Taft-amendment types
+ - The '{type} ADDRESS' expression is now allowed on the left hand-side
+ of an assignment
+ - Improved command completion in Ada
+ - Several bug fixes
+
+* New commands
+
+set print frame-arguments (all|scalars|none)
+show print frame-arguments
+ The value of this variable can be changed to control which argument
+ values should be printed by the debugger when displaying a frame.
+
+remote put
+remote get
+remote delete
+ Transfer files to and from a remote target, and delete remote files.
+
+* New MI commands
+
+-target-file-put
+-target-file-get
+-target-file-delete
+ Transfer files to and from a remote target, and delete remote files.
+
+* New remote packets
+
+vFile:open:
+vFile:close:
+vFile:pread:
+vFile:pwrite:
+vFile:unlink:
+ Open, close, read, write, and delete files on the remote system.
+
+* GDB on GNU/Linux and HP/UX can now debug through "exec" of a new
+process.
+
+vAttach
+ Attach to an existing process on the remote system, in extended-remote
+ mode.
+
+vRun
+ Run a new process on the remote system, in extended-remote mode.
+
+*** Changes in GDB 6.7
* Resolved 101 resource leaks, null pointer dereferences, etc. in gdb,
bfd, libiberty and opcodes, as revealed by static analysis donated by
target's overall architecture. GDB can read a description from
a local file or over the remote serial protocol.
-* Arrays of explicitly SIGNED or UNSIGNED CHARs are now printed as arrays
-of numbers.
+* 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 and MIPS).
+only ARM, M68K, and MIPS).
* GDB and the GDB remote stub, gdbserver, now support the XScale
iWMMXt coprocessor.
