Hello. x86 can not handle the rip-relative jmp/call instrsuctions, the probed task can be killed by general protection fault. I'll describe this in more details when I send the fixes. Now I am sending the preparations which (I hope) make sense anyway, please review.
My main concern is 3/7. I know absolutely nothing about instruction decoding, so I can only guess what, for example, OPCODE1() == 0xff or MODRM_REG() == 2 actually means. Please review. Ananth, David, please ack/nack the first change, it affects powerpc/arm.
