Subject: 68000 Address Error Exception Handler

I need to find/write an exception handler for 68000 based Macs which
would resolve the address error exception which is raised when 68000
attempts to access a word or long operand at an odd address. I am not
interested in resolving instructions at odd addresses; the compiler
takes care of that whereas dynamically sized arrays/structures without
explicit padding within the application creates problems with
operands. Although I'm looking for a solution for Mac, 68000 assembly
being the same across platforms, I thought I'd ask to a number of
newsgroups. Hence the big crossposting list. Sorry if any incovenience
is caused by that.

I would be interested in hearing about any routines from Motorola
itself, pointers about how to contact Motorola to ask for such a
beast, tips&tricks for solving this problem by myself in a reasonable
size/speed/time effective way, ready-to-use public domain routines,
literature to look at, any solutions by Apple or Macintosh user
groups, or other 68000 developers... Please reply to this account
(ertem@sunburn.stanford.edu) since I don't read all these newsgroups,
and I'll later post a summary.

Thanks a bunch
Have fun
Tuna
