*** 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.
-Here are the new commands for working with macros:
-
-** macro expand EXPRESSION
-
-Expand any macro invocations in expression, and show the result.
-
-** show macro MACRO-NAME
-
-Show the definition of the macro named MACRO-NAME, and where it was
-defined.

-* 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
+
+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.
