Do we really need any more opcodes? In college I have a faint recollection of learning that all you need to emulate any computer is less than 10 basic instruction types like L, ST, A, S, C, BC and SIO.
You'll also need a few logicals like N, O, SLL, SRL.
So why does the z390 portable mainframe assembler with z196 opcodes now have 1293 opcodes? (see z390\rt\test\testins1.mlc regression test source program which tests assembly of them all).)
