Actually, that makes me feel better. While I never had much trouble
writing extended asm, trying to do even the simplest things in basic
kept raising more and more questions. I just kept assuming I wasn't
getting it.
I'm not going to post my list of things I've discovered that don't work
or aren't safe in basic asm. I don't intend to put them in the docs, so
mostly they just serve as justifications for why my docs discourage the
use of basic asm and point people toward extended. And it doesn't sound
like I need to convince anyone here.
Such being the case, my current cut at docs for basic asm are in a pdf
at http://www.LimeGreenSocks.com/gcc/basic.pdf for at least the next few
days. It's about a page long, and much of the text was copied (with
minor mods) from the extended docs I wrote
(http://www.limegreensocks.com/gcc/Extended-Asm.html).
Any comments from formatting, grammar and punctuation to technical
content and accuracy are welcome.
