[Qemu-devel] [PATCH v3] The m68k gdbstub SR reg request doesnt include Condition-Codes

[Lucien Murray-Pitts <lucienmp.qemu@gmail.com>]

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 m68k_cpu_gdb_read_register for SR register.
