;; The following DFA description schedules instructions for speed. In
;; addition to the scheduling of instructions to remove stall cycles
;; (e.g., memory load), the scheduler will also pack multiple
;; instructions into a single cycle, using VLIW.
;; Each instruction comes in forms with and without long
;; constants. The long constant is treated as though it were also an
;; instruction. Thus, an instruction which used slot0, will use slot0
;; plus one of the other slots for the constant. This mechanism
;; ensures that it is impossible for 3 instructions to be issued, if
;; one of them has a long constant. This is necessary, because the
;; encoding of 3 instructions, plus a constant, will overrun the
;; 64-bit limit.

@item k
Stack register.
@item f
Pointer register. A register which can be used to access memory without
supplying an offset. Any other register can be used to access memory,
but will need a constant offset. In the case of the offset being zero,
it is more efficient to use a pointer register, since this reduces code
size.
@item t
A twin register. A register which may be paired with an adjacent
register to create a 32-bit register.

Any absolute memory address (e.g., symbolic constant, symbolic
constant + offset).

// picoChip Function Prologue : &__divmod15 = 0 bytes
// The picoChip instruction set has a divstep instruction which
// is used to perform one iteration of a binary division algorithm.
// The instruction allows 16-bit signed division to be implemented.
// It does not directly allow 16-bit unsigned division to be
// implemented. Thus, this function pulls out the common division
// iteration for 15-bits unsigned, and then special wrappers
// provide the logic to change this into a 16-bit signed or
// unsigned division, as appropriate. This allows the two
// versions of division to share a common implementation, reducing
// code size when the two are used together. It also reduces
// the maintenance overhead.
// Input:
// r0 - dividend
// r1 - divisor
// Output:
// r0 - quotient
// r1 - remainder
// R5 is unused
// Check for special cases. The emphasis is on detecting these as
// quickly as possible, so that the main division can be started. If
// the user requests division by one, division by self, and so on
// then they will just have to accept that this won't be particularly
// quick (relatively), whereas a real division (e.g., dividing a
// large value by a small value) will run as fast as possible
// (i.e., special case detection should not slow down the common case)
//
// Special cases to consider:
//
// Division by zero.
// Division of zero.
// Inputs are equal
// Divisor is bigger than dividend
// Division by power of two (can be shifted instead).
// Division by 1 (special case of power of two division)
//
// Division/modulus by zero is undefined (ISO C:6.5.5), so
// don't bother handling this special case.
//
// The special cases of division by a power of 2 are ignored, since
// they cause the general case to slow down. Omitting these
// special cases also reduces code size considerably.
// Handle divisor >= dividend separately. Note that this also handles
// the case where the dividend is zero. Note that the flags must be
