// Opcodes labelled "UNGEN" cannot be generated by the compiler. Quite a few,
// if they could, make little sense in the context of a JIT and could not
// work anyway. Opcodes technically present in sc4.c/sc7.c (respectively,
// the code emitter and peephole optimizer) are not necessarily ever generated.
// For example, lref.pri and lref.alt would be used if a reference could be
// stored in the global scope; but they can't, so they are unreachable.
//
// Most opcodes have been manually verified. A few have not, as they are only
// produced by the peephole optimizer, or not produced at all, or eliminated
// during optimization. We generate them anyway, just in case, but they have
// not been tested.
// lref.s.alt (phopt only)
// stor.alt (never)
// stor.s.alt (never)
// sref.s.alt (never)
// lidx.b (phopt only, probably impossible)
// idxaddr.b (phopt only, looks difficult)
// move.pri (eliminated in phopt)
// shl.c.pri (eliminated in phopt)
// shl.c.alt (eliminated in phopt)
// shr.c.pri (eliminated in phopt)
// shr.c.alt (eliminated in phopt)
// eq.c.alt (never)
// inc.alt (never)
// dec.alt (never)
// sdiv (never)
// nop (never in function bodies)

// Additionally, some opcodes which were supported in the earlier JIT are no

// lref.pri/alt
// sref.pri/alt
