What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 5.2:
+*** Changes since GDB 5.3:
+
+* d10v `regs' command deprecated
+
+The `info registers' command has been updated so that it displays the
+registers using a format identical to the old `regs' command.
+
+* Profiling support
+
+A new command, "maint set profile on/off", has been added. This command can
+be used to enable or disable profiling while running GDB, to profile a
+session or a set of commands. In addition there is a new configure switch,
+"--enable-profiling", which will cause GDB to be compiled with profiling
+data, for more informative profiling results.
+
+* Default MI syntax changed to "mi2".
+
+The default MI (machine interface) syntax, enabled by the command line
+option "-i=mi", has been changed to "mi2". The previous MI syntax,
+"mi1", can be enabled by specifying the option "-i=mi1".
+
+Support for the original "mi0" syntax (included in GDB 5.0) has been
+removed.
+
+Fix for gdb/192: removed extraneous space when displaying frame level.
+Fix for gdb/672: update changelist is now output in mi list format.
+Fix for gdb/702: a -var-assign that updates the value now shows up
+ in a subsequent -var-update.
* Multi-arched targets.
+HP/PA HPUX11, 32bit ABI (partial) hppa*-*-hpux* except hppa*64*-*-hpux11*
+
+* OBSOLETE configurations and files
+
+Configurations that have been declared obsolete in this release have
+been commented out. Unless there is activity to revive these
+configurations, the next release of GDB will have their sources
+permanently REMOVED.

+I960 with MON960 i960-*-coff
+
+* MIPS $fp behavior changed
+
+The convenience variable $fp, for the MIPS, now consistently returns
+the address of the current frame's base. Previously, depending on the
+context, $fp could refer to either $sp or the current frame's base
+address. See ``8.10 Registers'' in the manual ``Debugging with GDB:
+The GNU Source-Level Debugger''.
+
+*** Changes in GDB 5.3:
+
+* GNU/Linux shared library multi-threaded performance improved.
+
+When debugging a multi-threaded application on GNU/Linux, GDB now uses
+`/proc', in preference to `ptrace' for memory reads. This may result
+in an improvement in the start-up time of multi-threaded, shared
+library applications when run under GDB. One GDB user writes: ``loads
+shared libs like mad''.
+
+* ``gdbserver'' now supports multi-threaded applications on some targets
+
+Support for debugging multi-threaded applications which use
+the GNU/Linux LinuxThreads package has been added for
+arm*-*-linux*-gnu*, i[3456]86-*-linux*-gnu*, mips*-*-linux*-gnu*,
+powerpc*-*-linux*-gnu*, and sh*-*-linux*-gnu*.
+
+* GDB now supports C/C++ preprocessor macros.
+
+GDB now expands preprocessor macro invocations in C/C++ expressions,
+and provides various commands for showing macro definitions and how
+they expand.
+
+The new command `macro expand EXPRESSION' expands any macro
+invocations in expression, and shows the result.
+
+The new command `show macro MACRO-NAME' shows the definition of the
+macro named MACRO-NAME, and where it was defined.
+
+Most compilers don't include information about macros in the debugging
+information by default. In GCC 3.1, for example, you need to compile
+your program with the options `-gdwarf-2 -g3'. If the macro
+information is present in the executable, GDB will read it.

-* Changes in VAX configurations.
-
-Multi-arch support is enabled for all VAX configurations.
-
-* Changes in Alpha configurations.
-
-Multi-arch support is enabled for all Alpha configurations.
-
* New command "set max-user-call-depth <nnn>"
This command allows the user to limit the call depth of user-defined
to a bfd-format or binary file (dump and append), and back
from a file into memory (restore).
+* Improved "next/step" support on multi-processor Alpha Tru64.
+
+The previous single-step mechanism could cause unpredictable problems,
+including the random appearance of SIGSEGV or SIGTRAP signals. The use
+of a software single-step mechanism prevents this.
+
+*** Changes in GDB 5.2.1:
+
+* New targets.
+
+Atmel AVR avr*-*-*
+
+* Bug fixes

+Fix, by Joel Brobecker imported from mainline.
+
+gdb/439: gdb/291: On some ELF object files, gdb was reporting:
+dwarf2read.c:1072: gdb-internal-error: sect_index_text not initialize
+Fix, by Fred Fish, imported from mainline.
+
+Dwarf2 .debug_frame & .eh_frame handler improved in many ways.
