Hi,
I’ve tagged the 18.1.0-rc1 release. Please test, upload binaries, and report issues to the issue tracker.
Windows binaries are ready. I didn’t run into any issues.

These were built with llvm-project\llvm\utils\release\build_llvm_release.bat --x86 --x64 --version=18.1.0-rc1 using the script at llvmorg-18.1.0-rc1
It’s been a while since I did a macOS build, but for 18.1.0 I’m getting a failure while linking libomp.dylib:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
I will have to investigate what this problem is, but if anybody here has a clue please let me know. 
For some reason, when linking libomp.dylib, the Phase2 built clang does not pass libclang_rt.osx.a on the linker command line. As opposed to Apple’s clang from Xcode, which does add libclang_rt.osx.a. I am unsure why there is a difference.
I’ve uploaded the Solaris/amd and Solaris/sparcv9 tarballs:
1a88e61eaf3a43f3d2254567aa72da1a660b2026580047ab1087153481e04311 clang+llvm-18.1.0-rc1-amd64-pc-solaris2.11.tar.xz

Solaris/amd64 test results are unchanged from 17.0.6. However, Solaris/sparcv9 shows massive (about 30) regressions. The bulk and most worrysome ones are in in LLVM :: Transforms/SampleProfile and LLVM :: tools/llvm-profdata, which also don’t show up on the Solaris/sparcv9 buildbot. Need to investigate.
Linux/sparc64 is in progress, but the resource consumption (especially memory, flang in particular) seem to be getting worse and worse with every release. I had to reduce the parallelism to avoid this and restart the build since there’s no easy way to continue a partial build. This will take several days until the new build is done, unfortunately.
Commit 907ed77 is causing build failures on AIX since compiler-rt is not being built during Phase 1. I have a local fix that seems to be working (will update once the script is done running).
Are you cross-compiling? In any case, this is very likely related to this, and can be worked around by linking libomp to compiler-rt.
No, this is a native build on macOS. At least, I assume that is what the test-release.sh script does when I explicitly pass a target of arm64
Perhaps it’s not so much a cross-compilation issue, and more a question of which symbols the macOS SDK on arm64 provides. It seems that ___divdc3 isn’t there for some reason, but compiler-rt provides an implementation.
Linux PowerPC testing completed and uploaded, no regression found.

ninja check-all blocks on armv7a-linux-gnueabihf target due to libfuzzer tests build failure. I will file an issue for this. ninja check-llvm check-clang, check-lld and check-cxx run individually pass without failures.

Windows AArch64 shows no new regression since 17.0.6.
First I apologize if this is not the right place to post.
I tried to build on my MacBook Air M2 and am also stuck wit error at the end of Phase 2. But the error is different than the one previously mentionned.

I used the following commands:
export MACOSX_DEPLOYMENT_TARGET=10.9
./test-release.sh \
-release 18.1.0 \
-rc 1 \
-triple Arch64-apple-darwin23.4 \
-no-compare-files
I aalso get the same error at end of Phase 2 with 18.1.2
As far as I can determine from searching around, the isPlatformVersionAtLeast function should be provided by the clang builtins library, which on macOS is libclang_rt.osx.a. If it fails like this at the end of Phase 2, you should probably try to execute the link command line with -v, to see what it tries to link in, exactly.
I’m looking again at the initial problems that I got, and it looks like a critical thing is that Phase 2 needs to build and install at least the builtins library (so libclang_rt.osx.a) to make building Phase 3 possible. I had adjusted the test-release.sh script’s configure_llvmCore() function for this, but found out that build_llvmCore() also needs to be adjusted, to actually install the builtins, or any other desired runtimes.
So the overview is:
- Phase 1: only build the
clangcompiler binary, since nothing more should be needed to build follow-up phases. (It could be that even this phase needs to build at least the builtins librarylibclang_rt.osx.a, since code generated by the Phase 1clangbinary might refer to such builtin functions.) - Phase 2: only build and install the
clangcompiler binary, and all the requested runtimes. This is because Phase 3 will be built by Phase 2, and you would expect the Phase 3 compiler to be linked against its “own” libc++ and libunwind, not the system-provided one. - Phase 3: build and install everything, that is all the projects and runtimes the user asked for.
I made some adjustments to test-release.sh to install the runtimes during Phase 2, but for some reason, only the builtins libraries actually get installed. It completely skips the sanitizer libraries, libc++ and libc++abi!
Strangely enough, these do get built, and they are visible in the respective .obj dirs, but but ninja install seems to totally skip them. I have no idea why, it’s all CMake magic.
I tried without export MACOSX_DEPLOYMENT_TARGET=10.9, as indicated in How To Validate a New Release.
git clone --depth 1 --branch llvmorg-18.1.2 https://github.com/llvm/llvm-project.git llvm-project-tagged-18.1.2
cd llvm-project-tagged-18.1.2/llvm/utils/release
Then I edited test-release.sh to add options --system-site-packages --symlinks to create virtual environment. And run command:
./test-release.sh \
-release 18.1.2 \
-final \
-triple Arch64-apple-darwin23.4 \
-no-compare-files
Now I have both Phase 1 and Phase 2 completing. I get in Phase 3 the error you were having in Phase 2 with libomp.dylib:

Thanks! Thus have to wait until it’s solved in trunk and try to cherry pick the patch
