llvm dev - Dec 2016 - 3.9.1-rc2 is ready for testing

Hi,

I just tagged 3.9.1-rc2, so testing can begin.  There was a bug found in
-rc1 before I could send out a release announcement, so I decided to merge
the fix and tag -rc2 to save some testing cycles.

We can always use more testers, so if you are interested in helping, let
me know.

Thanks,
Tom

Windows looks good and the binaries are uploaded: (sha1sum)

0d0425c3e77ddad8b885ceb66513a3ab85738da8  LLVM-3.9.1-rc2-win32.exe
efc721b59fdfe4b51a71800966c70a872efe897f  LLVM-3.9.1-rc2-win64.exe

They were built with the attached batch file.

Cheers,
Hans

It looks like it's only present when _GLIBCXX_USE_SCHED_YIELD.  I'll see
if
I can figure out why it would be packaged this way unless anyone knows off
the top of their head.

Hi Tom,

There is a bug in upstream LLVM that existed in LLVM 3.9.0 as well so
it likely exists in the 3.9.1 rc too.

I've just put the patch up for review (
https://reviews.llvm.org/D27393 ). Once a fix is approved you may want
to back port it to the 3.9 release branch.

Thanks,
Dan.

Here's the failing tests for rc2 on SLES11.3 (glibc 2.11, libstdc++4.7).
I've done some amount of triaging what some critical elements of the
failures are.  Unabridged log is attached.

Failing Tests (94):
    LLVM-Unit :: ExecutionEngine/Orc/OrcJITTests/DummyRPC.TestAsyncIntInt
    LLVM-Unit :: ExecutionEngine/Orc/OrcJITTests/DummyRPC.TestAsyncVoidBool
    LLVM-Unit :: ExecutionEngine/Orc/OrcJITTests/DummyRPC.TestSerialization

    LLVM-Unit :: Support/SupportTests/ThreadPoolTest.AsyncBarrierArgs
    LLVM-Unit :: Support/SupportTests/ThreadPoolTest.GetFuture
    LLVM-Unit :: Support/SupportTests/ThreadPoolTest.PoolDestruction

All of these ^^ failed with:

terminate called after throwing an instance of 'std::future_error'
  what():  No associated state



    AddressSanitizer-x86_64-linux ::
TestCases/Linux/interface_symbols_linux.c

This fails with "sed: invalid option -- 'E'".  The OS X
manpage (
https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/sed.1.html)
says "The -E, -a and -i options are non-standard FreeBSD extensions and may
not be available on other operating systems."  It's present in GNU sed
4.2.2 but absent from sed 4.1.5 on SLES11.3.


    AddressSanitizer-x86_64-linux :: TestCases/Linux/new_delete_mismatch.cc

This fails with "syntax error near unexpected token `&'"
because  "|&"
shortcut is not yet supported in bash 3.2.

    ThreadSanitizer-x86_64 :: Linux/mutex_robust2.cc

These fail to find pthread_mutexattr_getrobust while linking.  pthread.h on
SLES11.3 defines pthread_mutexattr_getrobust and
pthread_mutexattr_getrobust_np (depending on options like __USE_GNU) but
libpthread contains only pthread_mutexattr_getrobust_np.

    ThreadSanitizer-x86_64 :: thread_name2.cc

^^ glibc 2.11 doesn't include 'pthread_setname_np'.

    libc++ ::
std/diagnostics/syserr/syserr.errcat/syserr.errcat.objects/system_category.pass.cpp

^^ these tests fail the 'msg == "Unknown error -1" '
assertion.  I don't
see an obvious reason for why this would fail.

All good for debian8 x86_64 and MIPS/MIPSEL:

95e43919516c916b885bb791ff361ec43e111215 
clang+llvm-3.9.1-rc2-mipsel-linux-gnu.tar.xz

clang+llvm-3.9.1-rc2-x86_64-linux-gnu-debian8.tar.xz

I'll run a few more tests for MIPSEL but I'm not expecting any problems.
I'll report back if there's any test failure.

Looking great on Debian on all archs (except armel but this is not a 
recent regression).
