GDB now supports debugging programs written in the D programming
language.
+* GDB now supports the extended ptrace interface for PowerPC which is
+ available since Linux kernel version 2.6.34. This automatically enables
+ any hardware breakpoints and additional hardware watchpoints available in
+ the processor. The old ptrace interface exposes just one hardware
+ watchpoint and no hardware breakpoints.
+
+* GDB is now able to use the Data Value Compare (DVC) register available on
+ embedded PowerPC processors to implement in hardware simple watchpoint
+ conditions of the form:
+
+ watch ADDRESS|VARIABLE if ADDRESS|VARIABLE == CONSTANT EXPRESSION
+
+ This works in native GDB running on Linux kernels with the extended ptrace
+ interface mentioned above.
