/* Value is 1 if it is a good idea to tie two pseudo registers
when one has mode MODE1 and one has mode MODE2.
If HARD_REGNO_MODE_OK could produce different values for MODE1 and MODE2,
for any hard reg, then this must be 0 for correct output.
Early documentation says SI and DI are not tieable if some reg can
be OK for SI but not for DI. However other ports (mips, i860, mvs
and tahoe) don't meet the above criterion. Evidently the real
requirement is somewhat laxer. Documentation was changed for gcc
2.8 but was not picked up by egcs (at least egcs 1.0). Having all
integer modes tieable definitely generates faster code. */
