/* 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. */
