+/* Ok, here are the rules for using these macros...
+
+ B*() is used to specify the base opcode bytes. Fields to be filled
+ in later, leave zero. Call this first.
+
+ F() and FE() are used to fill in fields within the base opcode bytes. You MUST
+ call B*() before any F() or FE().
+
+ [UN]*O*(), PC*() appends operands to the end of the opcode. You
+ must call P() and B*() before any of these, so that the fixups
+ have the right byte location.
+ O = signed, UO = unsigned, NO = negated, PC = pcrel
+
+ IMM() adds an immediate and fills in the field for it.
+ NIMM() same, but negates the immediate.
+ NBIMM() same, but negates the immediate, for sbb.
+ DSP() adds a displacement, and fills in the field for it.
+
+ Note that order is significant for the O, IMM, and DSP macros, as
+ they append their data to the operand buffer in the order that you
+ call them.
+
+ Use "disp" for displacements whenever possible; this handles the
+ "0" case properly. */
