I like to have all my variable data covered by R13, too. However,
this does mean I have to have separate coverage for hard-coded and LTORG
constants. A base register would handle it, but then there is base-less
programming to think of. I've also heard that there is some caching issue
with having data using the same base register as code -- or some such. Are
there other solutions for hard-coded and LTORG constants?
Sincerely,
Dave Clark
