*** Changes since GDB 5.2:
-* ``gdbserver'' now supports multithreaded applications on some targets
+* ``gdbserver'' now supports multi-threaded applications on some targets
-Support for multithreaded applications using LinuxThreads has been added
-for arm*-*-linux*, i[3456]86-*-linux*, mips*-*-linux*, powerpc*-*-linux*,
-and sh*-*-linux*.
+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.
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.
-

* REMOVED configurations and files
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.
