llvm dev - Jan 2016 - [3.8 Release] We have branched

And so the release process begins.

The 3.8 branch was created today from trunk at r257626, and the trunk
version was then bumped to 3.9.

Release blockers are tracked by http://llvm.org/PR26059. If you find
any bugs (either new or already in the tracker) that you think need to
be fixed before the release, please mark them as blocking this bug.

To get a change committed on the branch, first commit it to trunk as
usual, then reply to the commit message on the mailing list with
myself and the appropriate code owner CC'd, asking for the change to
be merged to the branch.

Release notes for 3.8 should be committed directly to the branch, or
sent to me in an email and I'll do it for you. If you made any
non-trivial changes in the last six months (or know someone else who
did), please make sure they get mentioned in the notes.

Next up on the schedule is preparing the first release candidate
(RC1). This will happen in a few days, once the branch is known to be
in good shape.

The hardest part of releasing is staying on top of everything. Please
help me out by CC'ing me on any bugs, commits, or other issues that
are relevant for the release. If I'm not CC'd, there's a large
chance
I will miss it.

Cheers,
Hans

Hi Hans,

I tried the release branch last night and I'm having problems building it.
The problem is that test-suite is now building as part of the Phase[123] builds
(because this project contains CMakeLists.txt's now) but cmake 3.0.2 (from
Debian Jessie) generates an invalid Makefile.
The error is:
	CMakeFiles/test-suite.dir/build.make:112: *** target pattern contains no
'%'.  Stop.
	CMakeFiles/Makefile2:199: recipe for target
'CMakeFiles/test-suite.dir/all' failed
And the referenced line of the generated makefile is:
	test-suite-stamps/test-suite-force-rebuild:
/home/das-local/llvm-release-3.8/release/branches_release_38/llvm.src/$<TARGET_FILE:clang>
it looks like cmake isn't fully expanding its generator expressions.

Looking at my logs, it looks like the test-suite used to configure in 3.6.2 but
didn't build as part of test-release.sh and then 3.7.0 stopped since we had
switched to cmake and there was no CMakeLists.txt.
I've always run the test-suite as a separate step as described in
http://llvm.org/docs/ReleaseProcess.html. Should we stop creating the
projects/test-suite symlink to get back to the behaviour from 3.7.0 or should we
do something else?

Hi Daniel,

Thanks for trying out the branch :-)

Yes, I made the script stop making the symlink in r257791 and merged
it to the branch. Did that not work for you, or were you at an earlier
revision?

Thanks,
