/* ROUTINES:	$$divI, $$divoI

   Single precision divide for signed binary integers.

   The quotient is truncated towards zero.
   The sign of the quotient is the XOR of the signs of the dividend and
   divisor.
   Divide by zero is trapped.
   Divide of -2**31 by -1 is trapped for $$divoI but not for $$divI.

   INPUT REGISTERS:
   .	arg0 ==	dividend
   .	arg1 ==	divisor
   .	mrp  == return pc

   OUTPUT REGISTERS:
   .	arg0 =	undefined

   OTHER REGISTERS AFFECTED:
   .	r1   =	undefined

   SIDE EFFECTS:
   .	Causes a trap under the following conditions:
   .		divisor is zero  (traps with ADDIT,=  0,25,0)
   .		dividend==-2**31  and divisor==-1 and routine is $$divoI
   .				 (traps with ADDO  26,25,0)

   .		NONE

   PERMISSIBLE CONTEXT:
   .	Unwindable.
   .	Suitable for internal or external millicode.
   .	Assumes the special millicode register conventions.

   DISCUSSION:
   .	Branchs to other millicode routines using BE
   .		$$div_# for # being 2,3,4,5,6,7,8,9,10,12,14,15
   .
   .	For selected divisors, calls a divide by constant routine written by
   .	Karl Pettis.  Eligible divisors are 1..15 excluding 11 and 13.
   .
   .	The only overflow case is -2**31 divided by -1.
   .	Both routines return -2**31 but only $$divoI traps.  */

/* TRUNCATED DIVISION BY SMALL INTEGERS

   We are interested in q(x) = floor(x/y), where x >= 0 and y > 0
   (with y fixed).

   Let a = floor(z/y), for some choice of z.  Note that z will be
   chosen so that division by z is cheap.

   Let r be the remainder(z/y).  In other words, r = z - ay.

   Now, our method is to choose a value for b such that

   q'(x) = floor((ax+b)/z)

   is equal to q(x) over as large a range of x as possible.  If the
   two are equal over a sufficiently large range, and if it is easy to
   form the product (ax), and it is easy to divide by z, then we can
   perform the division much faster than the general division algorithm.

   So, we want the following to be true:

   .	For x in the following range:
   .
   .	    ky <= x < (k+1)y
   .
   .	implies that
   .
   .	    k <= (ax+b)/z < (k+1)

   We want to determine b such that this is true for all k in the
   range {0..K} for some maximum K.

   Since (ax+b) is an increasing function of x, we can take each
   bound separately to determine the "best" value for b.

   (ax+b)/z < (k+1)	       implies

   (a((k+1)y-1)+b < (k+1)z     implies

   b < a + (k+1)(z-ay)	       implies

   b < a + (k+1)r

   This needs to be true for all k in the range {0..K}.  In
   particular, it is true for k = 0 and this leads to a maximum
   acceptable value for b.

   b < a+r   or   b <= a+r-1

   Taking the other bound, we have

   k <= (ax+b)/z	       implies

   k <= (aky+b)/z	       implies

   k(z-ay) <= b		       implies

   kr <= b

   Clearly, the largest range for k will be achieved by maximizing b,
   when r is not zero.	When r is zero, then the simplest choice for b
   is 0.  When r is not 0, set

   .	b = a+r-1

   Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y)
   for all x in the range:

   .	0 <= x < (K+1)y

   We need to determine what K is.  Of our two bounds,

   .	b < a+(k+1)r	is satisfied for all k >= 0, by construction.

   The other bound is

   .	kr <= b

   This is always true if r = 0.  If r is not 0 (the usual case), then
   K = floor((a+r-1)/r), is the maximum value for k.

   Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct
   answer for q(x) = floor(x/y) when x is in the range

   (0,(K+1)y-1)	       K = floor((a+r-1)/r)

   To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that
   the formula for q'(x) yields the correct value of q(x) for all x
   representable by a single word in HPPA.

   We are also constrained in that computing the product (ax), adding
   b, and dividing by z must all be done quickly, otherwise we will be
   better off going through the general algorithm using the DS
   instruction, which uses approximately 70 cycles.

   For each y, there is a choice of z which satisfies the constraints
   for (K+1)y >= 2**32.  We may not, however, be able to satisfy the
   timing constraints for arbitrary y.	It seems that z being equal to
   a power of 2 or a power of 2 minus 1 is as good as we can do, since
   it minimizes the time to do division by z.  We want the choice of z
   to also result in a value for (a) that minimizes the computation of
   the product (ax).  This is best achieved if (a) has a regular bit
   pattern (so the multiplication can be done with shifts and adds).
   The value of (a) also needs to be less than 2**32 so the product is
   always guaranteed to fit in 2 words.

   In actual practice, the following should be done:

   1) For negative x, you should take the absolute value and remember
   .  the fact so that the result can be negated.  This obviously does
   .  not apply in the unsigned case.
   2) For even y, you should factor out the power of 2 that divides y
   .  and divide x by it.  You can then proceed by dividing by the
   .  odd factor of y.

   Here is a table of some odd values of y, and corresponding choices
   for z which are "good".

    y	  z	  r	 a (hex)     max x (hex)

    3	2**32	  1	55555555      100000001
    5	2**32	  1	33333333      100000003
    7  2**24-1	  0	  249249     (infinite)
    9  2**24-1	  0	  1c71c7     (infinite)
   11  2**20-1	  0	   1745d     (infinite)
   13  2**24-1	  0	  13b13b     (infinite)
   15	2**32	  1	11111111      10000000d
   17	2**32	  1	 f0f0f0f      10000000f

   If r is 1, then b = a+r-1 = a.  This simplifies the computation
   of (ax+b), since you can compute (x+1)(a) instead.  If r is 0,
   then b = 0 is ok to use which simplifies (ax+b).

   The bit patterns for 55555555, 33333333, and 11111111 are obviously
   very regular.  The bit patterns for the other values of a above are:

    y	   (hex)	  (binary)

    7	  249249  001001001001001001001001  << regular >>
    9	  1c71c7  000111000111000111000111  << regular >>
   11	   1745d  000000010111010001011101  << irregular >>
   13	  13b13b  000100111011000100111011  << irregular >>

   The bit patterns for (a) corresponding to (y) of 11 and 13 may be
   too irregular to warrant using this method.

   When z is a power of 2 minus 1, then the division by z is slightly
   more complicated, involving an iterative solution.

   The code presented here solves division by 1 through 17, except for
   11 and 13. There are algorithms for both signed and unsigned
   quantities given.

   .   2	4	   4	     2

   .  16	4	   4	     2
   .  17       16	  18	    16

   Now, the algorithm for 7, 9, and 14 is an iterative one.  That is,
   a loop body is executed until the tentative quotient is 0.  The
   number of times the loop body is executed varies depending on the
   dividend, but is never more than two times.	If the dividend is
   less than the divisor, then the loop body is not executed at all.
   Each iteration adds 4 cycles to the timings.

   .  14       21+4n	 22+4n	   20+4n

   To give an idea of how the number of iterations varies, here is a
   table of dividend versus number of iterations when dividing by 7.

   There is some overlap in the range of numbers requiring 1 and 2
   iterations.	*/

   z = 2**24-1
   r = z mod x = 0

   so choose b = 0

   Also, in order to divide by z = 2**24-1, we approximate by dividing
   by (z+1) = 2**24 (which is easy), and then correcting.

   (ax) = (z+1)q' + r

   So to compute (ax)/z, compute q' = (ax)/(z+1) and r = (ax) mod (z+1)
   Then the true remainder of (ax)/z is (q'+r).  Repeat the process
   with this new remainder, adding the tentative quotients together,
   until a tentative quotient is 0 (and then we are done).  There is
   one last correction to be done.  It is possible that (q'+r) = z.
   If so, then (q'+r)/(z+1) = 0 and it looks like we are done.	But,
   in fact, we need to add 1 more to the quotient.  Now, it turns
   out that this happens if and only if the original value x is

/******************************************************************************
This routine is used on PA2.0 processors when gcc -mno-fpregs is used

ROUTINE:	$$mulI


DESCRIPTION:	

	$$mulI multiplies two single word integers, giving a single 
	word result.  


INPUT REGISTERS:

	arg0 = Operand 1
	arg1 = Operand 2
	r31  == return pc
	sr0  == return space when called externally 


OUTPUT REGISTERS:

	arg0 = undefined
	arg1 = undefined
	ret1 = result 

OTHER REGISTERS AFFECTED:

	r1   = undefined

SIDE EFFECTS:

	Causes a trap under the following conditions:  NONE
	Changes memory at the following places:  NONE

PERMISSIBLE CONTEXT:

	Unwindable
	Does not create a stack frame
	Is usable for internal or external microcode

DISCUSSION:

	Calls other millicode routines via mrp:  NONE
	Calls other millicode routines:  NONE
