-C ev67: 3.4 cycles/bitpair for 1x1 part
-
-
-C mp_limb_t mpn_gcd_1 (mp_srcptr xp, mp_size_t xsize, mp_limb_t y);
-C
-C In the 1x1 part, the algorithm is to change x,y to abs(x-y),min(x,y) and
-C strip trailing zeros from abs(x-y) to maintain x and y both odd.
-C
-C The trailing zeros are calculated from just x-y, since in twos-complement
-C there's the same number of trailing zeros on d or -d. This means the cttz
-C runs in parallel with abs(x-y).
-C
-C The loop takes 5 cycles, and at 0.68 iterations per bit for two N-bit
-C operands with this algorithm gives the measured 3.4 c/l.
-C
-C The slottings shown are for SVR4 style systems, Unicos differs in the
-C initial gp setup and the LEA.
-C
-C Enhancement:
-C
-C On the jsr, !lituse_jsr! (when available) would allow the linker to relax
-C it to a bsr, but probably only in a static binary. Plain "jsr foo" gives
-C the right object code for relaxation, and ought to be available
-C everywhere, but we prefer to schedule the GOT ldq (LEA) back earlier, for
-C the usual case of running in a shared library.
-C
-C bsr could perhaps be used explicitly anyway. We should be able to assume
-C modexact is in the same module as us (ie. shared library or mainline).
-C Would there be any worries about the size of the displacement? Could
-C always put modexact and gcd_1 in the same .o to be certain.
