[Dwarf-discuss] Question: ETA?

[David Blaikie]

Yeah - I mostly don't mind it taking as long as it takes.

Eleanor - is there something you're particularly interested in/waiting
for/etc? At least for myself, speaking as a clang/llvm debug info
maintainer, I'd be happy to see DWARFv6 prototyped there (with a "no
stability guarantee" caveat, because the spec isn't finalized - so it'd be
useful/applicable if you have use clang/lldb at matched revisions (or some
arbitrary "safe revisions" even - if clang got out ahead of lldb in some
incompatible ways) only) if you really want to experiment with new
features, for instance.

In terms of moving the spec forward faster - if we think it's worth it, I'd
consider more proactively discouraging/sidelining proposals that can be
implemented using existing extension mechanisms & ask that those come back
only with implementation experience as extensions (though I realize this
comes at the cost of consuming more of the extension space, which is a bit
limited in some areas). Prioritize things that create extension spaces and
stuff that's fundamental shifts in the way DWARF is encoded. But I'm not
sure those sort of changes are necessary/a major need right now.
