Thanks for your contribution.

It would be good to support a more stable version of LLVM.20.1.0.

Could you also change the buid.sh for the CI to trigger the build of svf on top of new LLVM here?

done, in the build.sh I have added 20.1.0 as stable.

Looks like brew install llvm@20 is not available. It might need a few iterations to update the build.sh and github actions to fix these configuration errors.

Tested with LLVM 19.1.7 - compilation is working fine. Let me know if anything else is required on my end.

Could you then update the build.sh and github action?

build.sh:

• Added a fallback mechanism to install Clang+LLVM via apt if the curl download fails.
• Introduced additional checks to validate the curl download process.

GitHub Actions:

• The workflow is getting cancelled -- possibly due to it taking too long.
• Is there a recommended way to test the workflow locally before pushing?

currently, trying act tool to replicate github actions workflow.

Currently, the tests are failing because the Test-Suite still has old .bc files that were built with LLVM 16. I ran the generate_bc.sh script with LLVM20 to rebuild everything, and that fixed about 98% of the test failures. There are still a few tests failing, and I’m working on fixing those. bsdb0y/Test-Suite@cbce00e

Could you help me figure out how to run generate_bc.sh in GitHub Actions? I tried adding it to the build-svf step after build.sh, but it didn’t work as expected.

[van-ema]

I get errors during linking of svf-llvm.
To fix we can force dynamic linking of passes component that includes the PassBuilder

I'm building with llvm 19.1.4

@yuleisui
before we can properly test the changes in this PR with GitHub Actions, I kindly request that we first review and merge the following Test-Suite PR: SVF-tools/Test-Suite#156.

It updates the test suite to be compatible with LLVM 20 and ensures all tests run correctly. Merging it first will help us get accurate test results here.

Could you clean up your pull request in test-suite? There are lots of svf.svf.bc files and pre.bc files committed. Please make sure the commit is clean with mimum changes.

Thank you for pointing that out! I had pushed the precompiled .bc files as we are using them, but I mistakenly forgot to clean up the .pre. and *.svf.bc files. I've already made the suggested changes and cleaned up the pull request to ensure it includes only the relevant files. Please let me know if there’s anything else I can do or adjust to make it merge.

thank you so much @van-ema for testing it on macOS. I have added a check for OS detection to CMakeLists.txt, so it is like: if macOS, then add passes to link bsdb0y@cb7bb31

[bsdb0y]

@yuleisui could you please approve the latest commit so we can confirm whether it's failing or success? It’s working perfectly on my end, I tested it locally on both Ubuntu and macOS, even using the act tool to simulate GitHub Actions. I’m happy to integrate this work if everything works out. Let me know if you need anything from my side!

@yuleisui I can see from the GitHub Actions that the code is compiling successfully on both environments, but the tests are failing. That’s because this PR (SVF-tools/Test-Suite#156) still needs to be reviewed, approved, and merged. Once that happens, it should fetch the latest test cases that are compatible with LLVM 20.
