I’ve tagged 14.0.0-rc2. Please upload the binaries to GitHub and report any bugs you find.


Windows is ready. Here are the sha256sums:

Since OpenMP runtime fails to build on Windows: openmp\runtime\src\kmp_affinity.cpp(951): error C2131: expression did not evaluate to a constant · Issue #53672 · llvm/llvm-project · GitHub got fixed, the OpenMP runtime is now part of the packages again.

Also, as discussed in Python 3.6 End of Life · Issue #53738 · llvm/llvm-project · GitHub LLDB is now built against a more recent version of Python (3.10).

The packages were built with the attached batch file: build_llvm_1400-rc2.bat.txt (5.2 KB)

With this rc2 I am seeing the same phenomenon as with the previous rc1, which is that way less regression tests are being run. For instance, with 13.0.1:

# Testing - built with clang
[1/1338] Running lint check for sanitizer sources...
[1337/1338] Running all regression tests
-- Testing: 98828 tests, 2 workers --

but with 14.0.0 rc1 only ~15000 tests are run:

# Testing - built with clang
[1/1227] Building CXX object tools/clang/tools/extra/unittests/clang-apply-replacements/CMakeFiles/ClangApplyReplacementsTests.dir/ApplyReplacementsTest.cpp.o
[219/220] Running all regression tests
-- Testing: 15038 tests, 2 workers --

I also have an idea what the culprit is: the new LLVM_ENABLE_RUNTIMES CMake option, and the associated new check-runtimes target: in the CMake files, the traditional check-all target now has check-runtimes as a dependency… This means that if there is any error in check-runtimes, the rest of check-all is completely skipped!

Am I correct in thinking that this is the cause for ~85000 missing tests?

Do we need some kludge to make check-all continue, regardless of the success or failure of check-runtimes ?

Can you file an issue for this?

I’ve now uploaded the Solaris binaries. sha256sums are

Fixes for all the build failures in rc1 have been integrated. Thanks!

There’s one issue that I almost missed due to Issue #54154 above, but got prominent when manually re-running the tests with

ninja -k0 check-llvm check-clang check-clang-tools check-compiler-rt check-polly check-mlir check-flang

(Hope I didn’t miss any above.)

Quite a number of tests now failed due to the change in runtime lib directory layout due to the use of -DLLVM_ENABLE_RUNTIMES=. I’ve filed Issue #54196 for this. The uploaded binaries work around it by configuring for x86_64-pc-solaris2.11 instead of the canonical amd64-pc-solaris2.11.

Linux PowerPC binaries are clean. I’ve uploaded the binaries:

Uploaded armv7-linux, aarch64-linux and WoA:

Looks mostly the same as rc1, except for the fact that I’m no longer seeing differences between Phase2 and Phase3 object files on aarch64. Curiously enough, they’re still there on armv7.

I’ve uploaded the PowerPC (AIX 7.2) binaries for rc2.

No new regressions were seen when testing RC2 on AIX.

Nothing special.
I just had something unusual in Ubuntu Jammy (the next one)
lldb Python files are installed in
instead of

(i just moved back the files as workaround)

Seems to be a change in Ubuntu, not a LLVM issue but documenting for others.
