Yes.  It will be related to that.  When updating the code, I searched 
for something that relied on the reverse lookup (regnum -> name) but 
couldn't find anything (at least nothing that affected the testsuite).

GDB is mapping:

	"$pc" -> NUM_REGS+NUM_PSEUDO_REGS+<builtin-pc>

and then failing:

	... -> "$pc"

because the mechanism isn't there.

I'll figure out a patch.
