What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 5.1:
+*** Changes since GDB 5.2:
+
+* ``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.
+
+* Multi-arched targets.
+
+DEC Alpha (partial) alpha*-*-*

+been commented out. Unless there is activity to revive these
+configurations, the next release of GDB will have their sources
+permanently REMOVED.

+
+testsuite/gdb.hp/gdb.threads-hp/ directory
+
+* New command "set max-user-call-depth <nnn>"
+
+This command allows the user to limit the call depth of user-defined
+commands. The default is 1024.
+
+* Changes in FreeBSD/i386 native debugging.
+
+Support for the "generate-core-file" has been added.
+
+* New commands "dump", "append", and "restore".
+
+These commands allow data to be copied from target memory
+to a bfd-format or binary file (dump and append), and back
+from a file into memory (restore).
+
+*** Changes in GDB 5.2.1:
+
+* New targets.
+
+Atmel AVR avr*-*-*
+
+* Bug fixes
+
+gdb/182: gdb/323: gdb/237: On alpha, gdb was reporting:
+mdebugread.c:2443: gdb-internal-error: sect_index_data not initialized
+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.
+Surprisingly enough, it works now.
+By Michal Ludvig, imported from mainline.
+
+i386 hardware watchpoint support:
+avoid misses on second run for some targets.
+By Pierre Muller, imported from mainline.
+
+*** Changes in GDB 5.2:
+
+* New command "set trust-readonly-sections on[off]".
+
+This command is a hint that tells gdb that read-only sections
+really are read-only (ie. that their contents will not change).
+In this mode, gdb will go to the object file rather than the
+target to read memory from read-only sections (such as ".text").
+This can be a significant performance improvement on some
+(notably embedded) targets.
+
+* New command "generate-core-file" (or "gcore").
+
+This new gdb command allows the user to drop a core file of the child
+process state at any time. So far it's been implemented only for
+GNU/Linux and Solaris, but should be relatively easily ported to other
+hosts. Argument is core file name (defaults to core.<pid>).
+
+* New command line option
+
+GDB now accepts --pid or -p followed by a process id.
+
+* Change in command line behavior -- corefiles vs. process ids.
+
+There is a subtle behavior in the way in which GDB handles
+command line arguments. The first non-flag argument is always
+a program to debug, but the second non-flag argument may either
+be a corefile or a process id. Previously, GDB would attempt to
+open the second argument as a corefile, and if that failed, would
+issue a superfluous error message and then attempt to attach it as
+a process. Now, if the second argument begins with a non-digit,
+it will be treated as a corefile. If it begins with a digit,
+GDB will attempt to attach it as a process, and if no such process
+is found, will then attempt to open it as a corefile.
+
+* Changes in ARM configurations.
+
+Multi-arch support is enabled for all ARM configurations. The ARM/NetBSD
+configuration is fully multi-arch.
