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.
