Hi Peter,
I haven't looked at your patch in detail, but some thoughts in no
particular order:
1) it would be very useful to separate and submit the mechanical
changes independent from any other changes in your patch. As Eli
mentioned, duplicating the -E printer is not acceptable. We should
refactor that code into a form acceptable for your work independently
of the rest of the patch.
2) It is generally bad form to have headers like NetSession.h #include
system-specific stuff (like sys/socket or netinet/in.h) these
#includes should move to a .cpp file. I like that you put the system
specific code in a platform abstraction layer, it just needs to be a
bit tighter.
3) I think we should have a high level discussion about how the new
dist-cc implementation integrates with clang. I had envisioned a
different *driver* on the client side that shared code but was
independent of the clang driver. It doesn't make any sense to
distribute many of the things the clang driver does (e.g. -Eonly, -ast-
dump, etc). If we can come to a design, I think a number of the
changes you made would be unneeded. This would basically amount to
your "-dist-preprocesslocally" option, but would be simpler. Once
that is working well, more aggressive models can be attempted.
4) It would be good to have some HTML documentation for this,
including end-user documentation on how to set it up and use it. This
should go in clang/docs.
5) Have you done any timings of this?
Thanks for working on this. It is very exciting to see progress on
this project! I know a number of people who are very interested in
this work,
-Chris
