I think you are looking for version 2.2. It targets the 8086 with
small code snippets for each p-code. You can start with James
Hendrix's site http://www.oxaero.com/Jim.asp, or the Dr. Dobb's
Small-C Resource CD can still be purchased at
https://store.ddj.com/product/8/Small-C-Resource. There are other
8086 and 'x86 versions available, but the 2.2 branch probably best
fits your style. The Dr. Dobb's CD has copies of articles and books
that should be helpful to you, too.
If you send me a private email, I can arrange for you to get a
'snap-shot' of my not-ready-for-prime-time version 2.2.1. It has some
corrections, extensions, additional optimizations, etc. The sources
have more extensive comments, and I have segregated the host dependent
and the target dependent information with separate headers, macros,
etc. There is code for both the compiler and SmallA assembler that
works with the 'free' VAL linker and the FreeDOS librarian. The code
can be auto-compiled or cross-compiled by K&R or ANSI compilers. You
should be able to extend it to work in 32 bit mode on 'x86 cpu's
easily enough. Look for my email address in the Google group's
comp.os.cpm archives. The documentation for my changes is pretty
slim, but maybe you can help get it started by capturing an email Q&A
stream with me.
Return to the
Search the comp.compilers archives again.
