[3.8 Release] RC2 has been tagged

Project Infrastructure Release Testers

Dear testers,

Release Candidate 2 has just been tagged [1]. Please build, test, and
upload to the sftp.

I know there are still outstanding issues from RC1, but there have
been a lot of merges going into the branch and I think it's time for
another round of RC testing.

This RC comes a little behind schedule, sorry about that, but I'm
still optimistic about hitting the target of releasing towards the end
of February.

Thanks for all the work you've put into this release so far!

Hans

ARM and AArch64 look good, uploaded. I'm not using any new distro, so
all the ABI issues are not showing, but they do exist in ARM/AArch64.

I've had some trouble getting compiler-rt to build on FreeBSD, but after a few minor hacks, I managed to make it build and test successfully for i386. For x86_64, however, there is still a problem in the tsan tests:

/tmp/gotsan.WXO5sLCzBa/gotsan.cc:(.text+0x22d9b): undefined reference to `__sanitizer::GetRSS()'
/tmp/gotsan.WXO5sLCzBa/gotsan.cc:(.text+0x22e7b): undefined reference to `__sanitizer::GetRSS()'
/tmp/gotsan.WXO5sLCzBa/gotsan.cc:(.text+0x22feb): undefined reference to `__sanitizer::GetRSS()'
clang-3.8: error: linker command failed with exit code 1 (use -v to see invocation)
projects/compiler-rt/lib/tsan/CMakeFiles/GotsanRuntimeCheck.dir/build.make:50: recipe for target 'projects/compiler-rt/lib/tsan/CMakeFiles/GotsanRuntimeCheck' failed
gmake[3]: *** [projects/compiler-rt/lib/tsan/CMakeFiles/GotsanRuntimeCheck] Error 1

E.g., at some point, GetRSS() got added or split out, but there is no FreeBSD variant of this function. So for now I am probably going to attempt to disable tsan only, and continue with the rest of the build.

x86{-64}, ppc64{le} (with fix for PR26173), armv{6,7}, aarch64 looks
good on openSUSE.

Thanks,

What version of openSUSE are you testing on Ismail? I don’t want us to duplicate the work :slight_smile:

Hi Nikola,

Hi,

I’ve uploaded clang+llvm-3.8.0-rc2-x86_64-apple-darwin.tar.xz now.

Without assertions, I get:

    AddressSanitizer-x86_64h-darwin :: TestCases/Posix/asan-symbolize-sanity-test.cc

  Expected Passes : 31525
  Expected Failures : 188
  Unsupported Tests : 889
  Unexpected Failures: 2

With assertions, I get:

Failing Tests (11):
    AddressSanitizer-x86_64-darwin :: TestCases/Posix/asan-symbolize-sanity-test.cc
    AddressSanitizer-x86_64h-darwin :: TestCases/Posix/asan-symbolize-sanity-test.cc

Same as RC1.

After disabling tsan for x86_64, the builds finally went OK, and all tests succeeded. So these tarballs now also have compiler-rt in them, though unfortunately still no libc++:
