14.0.0-rc4 has been tagged


I’ve just tagged 14.0.0-rc4, please test and upload the binaries. If everything goes well, this will be the last release candidate.

Also, the reason there was no -rc3 release was because there was a bug discovered right after I tagged -rc3, so I didn’t want to have everyone test a known buggy build.


CMake doesn’t like this:

CMake Error at /home/tcwg-buildslave/workspace/tcwg-llvm-release/tcwg-jade-03/rc4/llvm-project/compiler-rt/cmake/base-config-ix.cmake:189 (add_default_target_arch):

and something similar for get_compiler_rt_output_dir.

I’m using the command that worked for rc2:

Is anyone else hitting something similar?

Nothing new over rc2

For 14.0.0 rc4, I have built and tested on both FreeBSD 12 and 13. No additional patches were needed.

For the 32-builds I used -no-flang, as flang is currently not 32-bit clean, and I do not expect it will ever be.

After commit df2fcea78fb8, which reverted the bootstrapping build, the number of regression tests is again back to normal.

@tstellar: This seems to be because of the changes to test-release.sh. It’s behaving a bit strangely, in the sense that for rc2 it said that compiler-rt and libcxx & co were disabled (I didn’t notice this because it was running the tests for them anyway…), but now for rc4 it says they’re enabled and it errors out because COMPILER_RT_DEFAULT_TARGET_ARCH is empty. I can work around this by setting CMAKE_C_COMPILER_TARGET, but that’s probably not a very principled fix. In any case, the builds are in progress now, I’ll post the results as soon as they’re ready.

I’ve now uploaded Solaris/amd64 and Solaris/sparcv9 binaries:

No regressions compared to rc2.

I’m working on a patch for Issue #54196, which will be needed for 14.0.1 when it switches back to -DLLVM_ENABLE_RUNTIMES.

I’ve also run an x86_64-pc-linux-gnu build for good measure, but unlike rc2 that won’t build with the bundled GCC 9.3.0 (or 10.3.0) in Ubuntu 20/04. libcxxabi/src/cxa_aux_runtime.cpp FAILs to compile in Phase 1:

/var/llvm/reltest/llvm-14.0.0-rc4/rc4/Phase1/Release/llvmCore-14.0.0-rc4.obj/include/c++/v1/type_traits:554:53: error: there are no arguments to ‘__is_same’ that depend on a template parameter, so a declaration of ‘__is_same’ must be available [-fpermissive]
  554 | struct _LIBCPP_TEMPLATE_VIS is_same : _BoolConstant<__is_same(_Tp, _Up)> { };

I have no idea which version of GCC is required to build.



I am aware that rG26a1830e39ba (Using the Bootstrapping Build for LLVM releases) was reverted due to an issue, and then recommitted along with a fix. Then, I noticed the patch (along with the fix) was reverted once again prior to tagging rc4.

The removal of this patch: rG26a1830e39ba makes us unable to build on AIX (since we build compiler-rt as run times). As a result, I have reapplied that patch to my rc4 source since it allows me to build rc4 successfully.

I think we will need to find a solution for the runtimes issue that can work, or unfortunately, we will have to provide a build that deviates from the actual source in the release branch. :frowning:

I’ve uploaded the PowerPC (AIX 7.2) binary for rc4 that I’ve built.

Aside from the issue I mentioned previously, no new regressions were seen when testing RC4 on AIX.


@amy-kwan Does @rovka’s suggestion in 14.0.0-rc4 has been tagged - #6 by rovka fix the failure for you?

Hi @tstellar,
Thanks for the suggestion. The solution of setting CMAKE_C_COMPILER_TARGET does not work for me if I try to rebuild without the patch. My error is actually not at the CMake stage, though - it’s during the stage 1 build step.

We’re unable to build parts of compiler-rt when setting it as a project on AIX - so we usually build compiler-rt as a runtime (which is what rG26a1830e39ba helped accomplish before).

@amy-kwan Is this just an issue with the test-release.sh script or is it impossible to build on AIX at all?

@tstellar, I suppose it could be a little bit of both.

In terms of test-release.sh, the script currently defaults to building compiler-rt as a project (I was able to use the test-release.sh script when the patch I mentioned earlier was committed, since it added compiler-rt to -DLLVM_ENABLE_RUNTIMES).

With the build compiler we use, I am not able to build on AIX when compiler-rt is built as a project, due to build errors in compiler-rt that occur.

We’ve pretty much only been building LLVM on AIX when compiler-rt is built as a runtime, and I have really only been able to get a successful run of test-release.sh on AIX with compiler-rt in -DLLVM_ENABLE_RUNTIMES (so really, we’re able to build compiler-rt with the just-built compiler).

Out of interest, what kind of compiler-rt build errors are you getting? Are these errors occurring because now the library is compiled using the host compiler (which I assume is an AIX specific thing), instead of clang?

Finally managed to upload:

In general it looks a lot like rc2, but:

  • On AArch64 Linux, I’m seeing some new libarcher failures. These seem to be because the addr2line on the machine is too old, so I wouldn’t consider it a release blocker.
  • On armv7 I’m seeing some new lldb failures in the libcxx-related tests. These are probably a consequence of how libcxx is built (project vs runtime), so again I wouldn’t consider this a blocker. On the bright side, I’m no longer seeing any differences between Phase2 and Phase3 objects.

I’m not sure, but this seems to be related to building certain things as projects instead of runtimes similar to the issues that @amy-kwan encountered. I was able to run test-release.sh successfully after re-applying rG26a1830e39ba.The binary I’ve uploaded for PowerPC RHEL was built using that modified version of test-release.sh.

Besides this, there were no new failures.

This looks like your host system’s compiler (the RHEL one) does not have the <charconv> header. If you have access to the so-called “devtoolset” packages, you could attempt to install a newer version, and use that as the host compiler. RHEL even supports this officially.

Or if you want to build with clang, you can use the llvm-toolset packages on RHEL.

Ah, but as far as I know these still have to be able to find newer libstdc++ versions, which are only available via the devtoolset packages? (Maybe you could also build against libc++, but then your executables would become dependent on a libc++ runtime package, and they wouldn’t be interoperable with libstdc+±dependent packges.)

Oh you are right, thanks @DimitryAndric and @tstellar! I’ll look into that more.

Right, llvm-toolset should pull in the newer devtools libstdc++ in as a dependency, and the clang driver will find it: llvm-project/Gnu.cpp at main · llvm/llvm-project · GitHub

libc++ is not available in RHEL.
