[Qemu-devel] [PATCH] The m68k gdbstub SR reg request doesnt include Condition-Codes

[Lucien Murray-Pitts]

The register request via gdbstub would return the SR part
which contains the Trace/Master/IRQ state flags, but
would be missing the CR (Condition Register) state bits.

This fix adds this support by merging them in the m68k
specific gdbstub handler
