[llvm-dev] Longstanding failing tests - clang-tidy, MachO, Polly

Hi,

A few tests seem broken for a long time, some for more than a month. Would it
possible for respective owners to take a look please?

I'm at checkout 133a7e631cee97965e310f0d110739217427fd3d, compiling on
Windows 10.

These tests fail with Visual Studio 2019:

    Polly :: ScopInfo/memset_null.ll

  Expected Passes    : 57692
  Expected Failures  : 283
  Unsupported Tests  : 1941
  Unexpected Failures: 7

The clang-tidy tests fail since end of November-December.
The MachO tests fail since about the beginning of December.
The Polly test fails since a few days ago.

I'm using the following cmake cmd-line:

[llvm-dev] Longstanding failing tests - clang-tidy, MachO, Polly

I just XFAIL'ed the polly test; it was also failing on the polly bots.

The other tests you mentioned are not failing on any of the bots on
lab.llvm.org, as far as I can tell, including
http://lab.llvm.org:8011/builders/clang-x64-windows-msvc , which runs a similar
configuration to yours.  So it's going to be hard for anyone without your
exact environment to reproduce the issues.

[llvm-dev] Longstanding failing tests - clang-tidy, MachO, Polly

I'm seeing this on two different machines, with completely different
hardware. The git checkout is clean.
I've tried again, with the exact cmake cmd-line used on the MSVC bot, it
fails on the same tests.

The only difference I see is that the bot uses MSVC 16.3.7, whereas I use the
latest 16.4.3. The first 16.4 was released at the beginning of December, and
it's about the time where I started seeing the issues. The tests might fail
because of the new MSVC optimizer, this doesn't happen on Debug builds.

I'm also occasionally seeing crashes in opt, in LLVM ::
Transforms/InstCombine/strcpy-2.ll, but this is not 100% repro (using the exact
cmd-line as on the bot):

Reid, do you think it would be possible to upgrade
windows-gcebot2<http://lab.llvm.org:8011/buildslaves/windows-gcebot2> to
latest MSVC 16.4?

[llvm-dev] Longstanding failing tests - clang-tidy, MachO, Polly

The gen-dwarf* test failures actually seem like an MSVC compiler bug. This
variable somehow gets folded to true with MSVC, and extra unexpected
relocations are produced:
https://github.com/llvm/llvm-project/blob/master/llvm/lib/MC/MCDwarf.cpp#L1141

I will try to reduce it. I suspect it requires this specific MSVC release
to reproduce, and our buildbots must not have it.

[llvm-dev] Longstanding failing tests - clang-tidy, MachO, Polly

So, for this test case:

extern "C" void shouldBeUnconditional();
extern "C" void shouldBeConditional();
extern "C" void otherCall();
void testFn(bool Bool1, bool Bool2) {
  Bool1 |= Bool2;
  shouldBeUnconditional();
  if (Bool1)
    shouldBeConditional();
  if (Bool2) {
    otherCall();
    if (Bool1)
      otherCall();
  }
}

MSVC generates this buggy asm:

$ cl -c -Fat.asm msvc-bool-bug.cpp -O2
Microsoft (R) C/C++ Optimizing Compiler Version 19.24.28315 for x64
Copyright (C) Microsoft Corporation.  All rights reserved.

msvc-bool-bug.cpp

$ cat t.asm
...
; Line 6
call shouldBeUnconditional
; Line 8
call shouldBeConditional
...

There is no conditional branch between these two calls, but if both Bool1
and Bool2 are false, the second call should not execute.

I went to file the issue, but I suspect that this report is a duplicate:
https://developercommunity.visualstudio.com/content/problem/845933/miscompile-boolean-condition-deduced-to-be-always.html

I posted my repro there.

It's not clear if we should do anything in LLVM to work around the problem,
or if we should just wait for the next release.
