No, it does seem deleted, I can't find it. I can only find its
deletion in the patch, not any re-insert or rewrite and I can't
find this information in the web-pages at limegreensocks. To
wit: where's the corresponding information; the replacement for
the section which started with "Sometimes you need to make an
@code{asm} operand be a specific register, but there's no
matching constraint letter for that register" and had the two
"sysint" examples? Maybe best placed in a separate subsection
cross-referenced from the "top" Extended-Asm Remarks section or
when first discussing constraints, in the "Output Operands"
subsection.
You are correct, I should not have removed this information. After
re-reading the original text several times to try to puzzle out exactly
what it was trying to say, I did feel the need to rephrase it however.
Then there's the question of where this text goes. Like you, I looked
at the idea of a new section, but it doesn't seem like it really merits
its own section. Putting it in the Output section sounds good, but it's
pretty big for that and kinda off-topic. And it would really have to be
repeated in the Inputs section as well. Yuck.
So, how about this:
1) I put the (rephrased) text and examples at the end of "Local Reg
Vars" page (starts with "Sometimes"):
http://www.LimeGreenSocks.com/gcc/Local-Reg-Vars.html
2) In the constraint paragraph for both Input and Output, I added this:
"If you must use a specific register, but your Machine Constraints do
not provide sufficient control to select the specific register you want,
Local Reg Vars may provide a solution (@pxref{Local Reg Vars})."
Acceptable? To see the changes in patch form, check out

Anything else? Or time to re-post the patch to the list?
But, speaking of that, I
can't find anyone mentioning the copyright issue. Maybe people
didn't want to scare you away... Someone has said that FSF were
moving towards it sometimes wouldn't be required anymore, but
that comment was made about a year ago and I don't know if
anything has actually changed, so: assuming this is "still"
required, are copyright assignment papers in place with the FSF
for these changes? I can't find any "dw" (or maybe too many) in
the canonical copyright.list just refreshed so I can't tell.
It would be a bummer to just find out about this now, but fortunately
Jonathan Wakely and Ian Lance Taylor already helped walk me thru all
this copyright stuff.
I can't see the copyright.list to which you are referring, but the email
I received from Donald Robertson at FSF on August 7, 2013 stated "Your
assignment/disclaimer process with the FSF is currently complete."
My name is David Wohlferd (it was in the changelog). If I'm not on the
official list, please let me know how to proceed.
Thanks again for your time,
