On the CMake side, I'm not sure. I think it's just a matter of using the
"install()" functions to install them into the appropriate place in
the
tree. They weren't installed by CMake in the first place; I was going to do
that, which is when I was told they shouldn't be distributed.

For Debian packaging, there are a few things.
1) revive the llvm-X.Y-tools.* files, which were in LLVM 3.7. See:
http://anonscm.debian.org/viewvc/pkg-llvm/llvm-toolchain/branches/3.7/debian/
.
2) add the llvm-X.Y-tools entry back into control. Compare
http://anonscm.debian.org/viewvc/pkg-llvm/llvm-toolchain/branches/3.7/debian/control?revision=1843&view=markup
 and
http://anonscm.debian.org/viewvc/pkg-llvm/llvm-toolchain/branches/3.8/debian/control?revision=1881&view=markup
.
3) update the "rules" script as necessary to support the above,
copying
files into the places that the Debian package layout expects

Thanks for the pointers. I'll try to work out something this week. I may
come back for more help, but I have enough at least to get me started.

Some update on this.

Turns out, these executable are installed when using -DLLVM_INSTALL_UTILS=1
with cmake, so that simplify this.

This is where I'm not sure how to proceed. How do I contribute to that
repository ? Is that debian owned ? What is the process to submit a patch ?

Yes, it is Debian-owned. When I made the changes to use CMake, I sent
patches directly to Sylvestre Ledru (CCd), who maintains the
LLVM/Clang/etc. packages for Debian.

FWIW, I second Reid's sentiment about having things like "not" in
the
standard $PATH. They are there in the older versions of LLVM, albeit with
version suffixes (e.g. /usr/bin/not-3.7). If it's possible, it would be
nice to hide them away in /usr/lib/llvm-<version>/bin, or perhaps a
utils-specific directory. I think it would then just be a matter of adding
that to $PATH before running lit tests.

I would offer to help write patches, but you would be at the mercy of my
near non-existent availability.

Cheers,
Andrew
