/*********************************************************************/
/* Archaeologist's note: */
/* */
/* The two following structures were added by Jan Jaeger 2010-08-29 */
/* when he wrote this module. */
/* */
/* At that point in time, z/Architecture already had a slew of */
/* additional facilities, including decimal floating point, though */
/* not all of them were published by the date Jan wrote this. */
/* */
/* However, judging by the way the z/Architecture facilities are */
/* defined below, it would appear to be that the intent of ALS2 was */
/* to base z architecture and that increasing numbers would be the */
/* various level sets of the new models. */
/* */
/* The only place I have been able to determine a dependency on ALS3 */
/* is in dyncrypt.c where the presence of the various facilities are */
/* tested against the bit map in the CPU. Here ARCHLVL ESAME gets */
/* you different bahaviour from ARCHLVL z. */
/* */
/* If ARCHLVL ESAME is indeed the original z, then the ALC */
/* instruction et al. should receive separate treatment in ESA and */
/* ESAME vs z in that it is RXE in RSA and RXY in z (there are not */
/* many instructions that share this behaviour, but they are likely */
/* to trip you on CMS in ESA mode. */
/* */
/* The actual feature names are define in featxxx.h files. The */
/* conditinal definition of FEATURE_INTERLOCKED_ACCESS_FACILITY_2 in */
/* feat900.h is my doing, out of ignorance at the time. */
/* */
/* In the real world (that is, IBM's) feature membership is defined */
/* in Appendix B of the PoO, though the instruction definition also */
/* includes the lack of the facility as causing a program exception. */
/* */
/* You may wish to contrast this defintion to the HLASM MACHINE() */
/* option in SC26-4941-07 (somewhat abbreviated and paraphrased */
/* here). */
/* */
/* S370: System/370 machine instructions, including those with a */
/* vector facility. */
/* */
/* S370XA: System/370 extended architecture machine instructions, */
/* including those with a vector facility. [370 I/O replaced by */
/* XA.] */
/* */
/* S390E: ESA/370 and ESA/390 architecture machine instructions, */
/* including those with a vector facility. */
/* */
/* ZSERIES: z/Architecture systems. */
/* ZSERIES-2: add long displacement facility. */
/* ZSERIES-3: add z9-109 instructions. */
/* ZSERIES-4: add z10 instructions. */
/* ZSERIES-5: add z196 instructions. */
/* ZSERIES-6: add zEC12 instructions. */
