I have an idea for a GNU-Make project.
* Separate Make's job-control from the dependency walking. Right now,
theses are somewhat tangled up, due to history. It would be nice to
separate these into distinct components. One wrinkle may be that
single-threaded invocation might need to preserve the
(implementation-defined) order of dependent rule execution, as
makefiles that do not completely specify dependencies might be relying
on that.
I ran into this problem with my hack to add a module-server into make,
and hacked around it in an ugly fashion.
(I've not run this by the GNU-Make maintainers)

Martin,
I've been looking into something similar to the scheduler for GCC
parallelizing. Its a lot harder
than it seems due to IPA passes and other things like IPO. Not sure how
Richard was planning to
handle that and unfortunately I've been busy and unable to write up my
ideas for scaling GCC.
Since it may be awhile before it reaches the wiki page here is a link to
a rough draft of my
ideas:https://docs.google.com/document/d/1po_RRgSCtRyYgMHjV0itW8iOzJXpTdHYIpC9gUMjOxk/edit?usp=sharing
I will be exploring the tooling issues when I'm time as that was my next
step.
Sorry if there are grammar issues as its a rough draft,
Nick
