What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 6.6
+*** Changes since GDB 6.7
+
+* 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.
+
+* 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.
+
+* 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).
+
+* 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.
+
+* New commands
+
+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.
+
+*** 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
+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
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.
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.
+
* New commands
set remoteflow
Read or write contents of an spufs file on the target system. These
packets are available only on the Cell/B.E. SPU architecture.
+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).
+
* Removed targets
Support for these obsolete configurations has been removed.
