 * Tables are composed in two parts:
 *
 * - 1st part (index 0-7) are identified by the reg field of MODRM byte
 *   if the MODRM is < 0xc0. reg field can be used directly as an index to table.
 *
 * - 2nd part (8 - 0x47) are identified by the MODRM byte itself. In that case,
 *   the index can be calculated by "index = MODRM - 0xb8"
