RE: [PATCH v2 REPOST] dtc: Add support for named integer constants

Even if everyone can't make it, how about a BoF session at ELC 2012? I
haven't had any time to contribute recently, but am tremendously
interested in moving this forward.

John, David,

What can we do to reach consensus on expanding dtc to handle named
constants, or in general any future direction to extend the syntax

with

quoted

expressions etc.?

Hrm, so, I'm not at all keen to add a named constant syntax without

at

least having an outline of what a future macro/function syntax would
look like.

Which is where I thought it was left earlier...? :-)
And it's not just what the macro/function syntax will look like,
but also how these will play into a more generalized expression
handling mechanism.  Defining something one-off now that doesn't
fit well into a long term plan is less than ideal.

Yes, I know that is tantamount to requiring the whole, larger
picture be solved first.  But Dave is right -- at least an outline
of the direction.  Seriously, the lexical problems can form some
of the nastiest gotchas if we're not careful from the onset.

The latter is almost certain to permit the former as a subcase, and
I'd really rather not end up with two different syntaxes for
constants.

Exactly.

Unfortunately, much as I'd like to get all these extended features
into dtc,

Agreed....

Will either of you be attending Linaro Connect or ELC 2012 in

February

by any chance? We could get together and talk this through in

person if

you are...

Not for me, I'm afraid.

Only if they are in Austin. :-)  Which is to say "Sorry, no."
