/*
when I say JIT, I mean load time, not execution time.

notes:
	qc jump offsets are all constants. we have no variable offset jumps (other than function calls/returns)
	field remapping... fields are in place, and cannot be adjusted. if a field is not set to 0, its assumed to be a constant.

optimisations:
	none at the moment...
	instructions need to be chained. stuff that writes to C should be cacheable, etc. maybe we don't even need to do the write to C
	it should also be possible to fold in eq+ifnot, so none of this silly storeing of floats in equality tests

	this means that we need to track which vars are cached and in what form: fpreg, ireg+floatasint, ireg+float.
	certain qccx hacks can use fpu operations on ints, so do what the instruction says, rather than considering an add an add regardless of types.

	OP_AND_F, OP_OR_F etc will generally result in ints, and we should be able to keep them as ints if they combine with other ints.

	some instructions are jump sites. any cache must be flushed before the start of the instruction.
	some variables are locals, and will only ever be written by a single instruction, then read by the following instruction. such temps do not need to be written, or are overwritten later in the function anyway.
	such locals need to be calculated PER FUNCTION as (fte)qcc can overlap locals making multiple distinct locals on a single offset.

	store locals on a proper stack instead of the current absurd mechanism.

	eax - tmp
	ebx - prinst->edicttable
	ecx	- tmp
	edx - tmp
	esi - debug opcode number
	edi - tmp (because its preserved by subfunctions
	ebp -

  to use gas to provide binary opcodes:
  vim -N blob.s && as blob.s && objdump.exe -d a.out


  notable mods to test:
  prydon gate, due to fpu mangling to carry values between maps
