llvm dev - Feb 2019 - [8.0.0 Release] rc2 has been tagged

Dear testers,

8.0.0-rc2 has been tagged from the release_80 branch at r353413.

Please run the test script, share your results, and upload binaries.

I'll get the source tarballs and docs published as soon as possible,
and binaries as they become available.

Thanks,
Hans

Hello,

We have started to build the 8.x branch and part of our build process is to run
check-clang, check-llvm and check-lld on Linux, Windows, Macos and FreeBSD. Is
there a test report or file we can collect in the CI and share with the
community if there is interest?

Hi Tobias,

Thank you for testing the release branch!

The test runner doesn't produce any report file. If you want to share
results, what is interesting for us is the output of the check-llvm,
etc. steps in the cases there are test failures.

Thanks,
Hans

Hi,

i've noticed a compile error with rc2 and libc++ (release_80 @svn). looks
similar to https://bugs.llvm.org/show_bug.cgi?id=40559

rc2 build on Ubuntu 16.04 saw a stage 2/3 mismatch on X86IselLowering.cpp.o
-- I didn't try to build rc1 for 16.04 but I can try it now to see if
it's
there too.

I can pass along logs if anyone wants to investigate.

rc1 did not exhibit this mismatch.  A repeat of the rc2 build repeated the
mismatch.  I diff'd the disassembly between phase 2 and phase 3 and the
difference is the same on both builds.  The difference follows:

This is quite odd, because libc++ trunk has no mentions of `_Float16`, and
I see none here:

Unfortunately I had to disable compiler-rt for this test run, as most of the
sanitizers are totally broken.  They get into an endless recursive loop between
AsanTSDGet() and the __tls_get_addr() interceptor, and crash with DEADLYSIGNAL
due to stack overflow.  I haven't found the time to further diagnose this.

Main test results on amd64-freebsd11:

  Expected Passes    : 53882
  Expected Failures  : 220
  Unsupported Tests  : 1081
  Unresolved Tests   : 10
  Unexpected Passes  : 3
  Unexpected Failures: 60

Main test results on i386-freebsd11:

  Expected Passes    : 53729
  Expected Failures  : 236
  Unsupported Tests  : 903
  Unresolved Tests   : 10
  Unexpected Passes  : 5
  Unexpected Failures: 178

The unresolved tests are due to a number of tests hanging in <defunct>
state, forcing me to kill their parent .py processes.

sounds like it's a regression from rc1? Even if you don't have time to
