I would appreciate any help in this reload problem
that I have been struggling with for some time:
I completed a gcc back end port to a processor that
supports both displaced and indexed addressing modes
for load, but only displaced for store. For example:

Um, this just is a collapse of some large macro.
The original compiles into a compiler that refuses to

The point I was making was that if you think there's a problem with that
macro, and you've posted to the list to ask if anyone can

that this macro is ok (I have extensively verified
that it works), and to keep the
initial message small. I have attached my complete
configuration file this time.

This may be easier if you do it the other way. I.e.
