64-bit support required some major changes to regs.dat; clean some of it up (re-introduce patterns, where appropriate) and allow a single register to belong to multiple disassembly classes; also keep track of the x86 register number again.

# 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.
