/* This file holds various tables for the TMS320C80 (MVP).

   The opcode table is strictly constant data, so the compiler should
   be able to put it in the .text section.

   This file also holds the operand table.  All knowledge about
   inserting operands into instructions and vice-versa is kept in this
   file.

   The predefined register table maps from register names to register
   values.  */


/* Table of predefined symbol names, such as general purpose registers,
   floating point registers, condition codes, control registers, and bit
   numbers.

   The table is sorted case independently by name so that it is suitable for
   searching via a binary search using a case independent comparison
   function.

   Note that the type of the symbol is stored in the upper bits of the value
   field, which allows the value and type to be passed around as a unit in a
   single int.  The types have to be masked off before using the numeric
   value as a number.
