You bumped the register numbers correctly, but you also need to add the correct padding to the NUMREGBYTES or you might not get a large enough memory block for the register struct. You added 2 32 bit regs, so it should change to: /* 17 64 bit regs and 5 32 bit regs */ #define NUMREGBYTES ((17 * 8) + (5 * 4)) The rest should be fine. I can test this and add it to the merge queue with the NUMREGBYTES change, unless you disagree.
