The compilers share a bit of code through copy-paste. I was wondering
if there are any important changes in recent years that were made
in a popularly used compiler (ie. 8[cal]) that might benefit other
compilers (ie. k[cal])?
Also, is there any documentation out there other than "How to
Use the Plan 9 C Compiler" and "Plan 9 C Compilers" that cover
the compilers? I've been perusing the code and some of the
code takes quite a while to figure out. Some quick notes would
go a long way (ie. "this function is a recursive tree walk that
checks types and inserts casts").

We do try to make the changes in all the compilers when
the changes are general, though that's no guarantee that
things haven't slipped through.

A more detailed implementation document for any one
of the compilers is yet to be written.
More seriously, I found that matching the text in
section 5 of /sys/doc/compiler.ps against the compiler
code was quite informative. It would be great if
there were better documentation.

It looks like 5[cal] will benefit, too, considering efforts going on for
ts7200 and simpad.

reading the compilers is enough doc.

5[cal] already is popularly-used, as is q[acl]

it's almost coming up as a cpu server, I just have to finish up making
memory mapping sane.
