Not sure it's worth bothering with in palcode-clipper - for Linux it's

BTW, out of curiosity - what was
case 5: /* illoc */
default: /* unexpected instruction-fault type */
about in that switch in do_entIF()?
All documentation I'd been able to find had only 0..4 as expected
values (bpt/bugcheck/gentrap/fen/opdec)...
No idea.
Historical git (cd52cb6178a7, v2.4.8 -> v2.4.8.1) suggests it's related to shark_mv, so
perhaps a later revision of DEC PALcode. But I have no corresponding documentation.
