 Subj: BUG IN 68K+ / AND /MOD        Status: PUBLIC MESSAGE

 I don't have the 68000 metacompiler with me.  But I don't see a problem
 with the example you gave, unless the assembler is generating the wrong
 code.  The flags get set by the  (SP) D1 MOVE, in  the definition of /,
 then the bottom byte of D2 gets initialized by the SMI instruction in
 wm/mod then sign extended to 16-bits then 32-bits.  It looks kosher from
 here; if there is something I don't understand about how the MOVE
 instruction sets flags and SMI responds to the flags, could you please
 explain the bug to me further and give me an example of which math
 operation fails.  I thought I tested all the divide operators for all
 the possible combinations of signs etc. but if you can give me a
 specific set of arguments and results that are incorrect I'll get it
 fixed for you right away.  Don't forget we are Forth-83 compliant so
 division is floored.
