What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 6.6

+*** Changes in GDB 6.6
+
+* 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.
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).
+only ARM and MIPS).
* GDB and the GDB remote stub, gdbserver, now support the XScale
iWMMXt coprocessor.
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.
+
* New commands
+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
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.
+
* New native configurations
OpenBSD/sh sh*-*openbsd*
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
+ 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.

+
+ 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
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.
