[Philippe Antoine via Phabricator via cfe-commits]

catenacyber added a comment.

This commit has broken oss-fuzz workflow for rust projects.
I do not know if the fix is https://reviews.llvm.org/rG66e2772e4285588ccc3bcdb5f392c8326debbd7d

Scenario is

  export RUSTFLAGS="--cfg fuzzing -Cdebuginfo=1 -Cforce-frame-pointers -Zinstrument-coverage -C link-dead-code -C link-arg=-lc++"
  git clone https://github.com/ctz/rustls && cd rustls
  cargo fuzz build -O
  ./fuzz/target/x86_64-unknown-linux-gnu/release/client ./fuzz/target/x86_64-unknown-linux-gnu/release/client
  llvm-profdata merge -sparse default.profraw -o profdata

Current output is

  warning: default.profraw: malformed instrumentation profile data
  error: no profile can be merged

Scenario does not output error for in 13.0.0-rc2

Error does not happen on commit 69cdadddecaf97f572c311aa07044f79a5b8329a <https://reviews.llvm.org/rG69cdadddecaf97f572c311aa07044f79a5b8329a> just previous this integration, if we add `git cherry-pick a6c14fba70e170a279f7e77f068368f09d8c5eaf` to fix the other pending bug which was fixed in 13.0.0-rc2
Error happens on commit a1532ed27582038e2d9588108ba0fe8237f01844 <https://reviews.llvm.org/rGa1532ed27582038e2d9588108ba0fe8237f01844> even if we `git cherry-pick a6c14fba70e170a279f7e77f068368f09d8c5eaf` and fix the conflict about only llvm/test/tools/llvm-profdata/Inputs/c-general.profraw
