68000 C-Compiler C68, Version II, Patch Number 3 ================================================ two errors were reported from the net and fixed: 1.) There was an error in optimize.c, peep_and() which converted move.w 0(a0,d0.l),d0 and.l #65535,d0 to clr.l d0 move.w 0(a0,d0.l),d0 i.e. the source depends on the target (d0). this is now checked for. The only other case where an operand depends on a data register would be move.w d0,d0. Other addressing modes exist (pc,d0.l), but are not used by the compiler. move.l d0,d0 is already eliminated at this point. There should be a function which very generally checks such dependencies. 2.) There was a problem doing arithmetic with enums. The net convinced me that C should handle enums less strict than PASCAL. So I convert enums to int in forcefit and to short in forceft2, knowing that enu Christoph van Wuellen
