That is fine.The real problem here is that the Common Registers of PowerPC are not uniform across the chips. I think the only ones that can truly be said to be common are R0-R31,pc,msr,lr,ctr,flags The macros defined, assume a whole lot about what is common, that isn't. And having written an "old stub" for the MPC860, I can confidently say that old stubs did not supply zeros where fpscr is, they didn't send anything as GDB did not expect anything.
Part of the definition is that the packet can grow and grow and grow. You just can't go back and re-format it.Obviously there would need to be some understanding in the stub of what registers GDB used, but I fail to see that GDB is ever going to permenantly define a packet layout and stick to it.
