# $Id$
#
# List of registers and their classes; classes are defined in nasm.h
#
# The columns are:
#
# register name, assembler class, disassembler class(es),
# NASM register number, x86 register number
#
# If the register name ends in +, then it is repeated 8 times
# with the following changes:
# - a numerical tail to register number is incremented
# - the NASM and x86 register numbers are incremented
#
# For 16-register register sets, two + lines are required.
#
# Legacy Registers
# 000-007 = 8-bit Registers
# 010-017 = 16-bit Registers
# 020-027 = 32-bit Registers
# System Registers
# 100-107 = Segment Registers
# 110-127 = Control Registers
# 130-147 = Debug Registers
# 150-167 = Test Registers
# Legacy Extended Registers
# 200-207 = FPU Registers
# 210-217 = MMX Registers
# 220-227 = XMM Registers (XMM0-XMM7)
# x64 Extended Registers
# 400-407 = 8-bit Extensions (SIL/DIL/BPL/SPL)
# 410-417 = 8-bit Registers (R8B-R15B)
# 420-427 = 16-bit Registers (R8W-R15W)
# 430-437 = 32-bit Registers (R8D-R15D)
# 440-457 = 64-bit Registers (RAX-RDI+R8-R15)
# 460-467 = XMM Extended Registers (XMM8-XMM15)
# Special Registers
# 0500 = RIP (for RIP-relative Addressing)
# General-purpose registers
