Yupp made the change. Have never seen such a message before and I wasn't even sure as to why my mail was private (changed it to public now). Is something more expected from my side ? I am guessing we can try closing and opening this PR if something in CI fails due to that ! |
|
I think one of the checks has been queued since quite some time but isn't running. |
|
Hi @aheejin The checks pass as expected. I guess this should be ready ! |

As I said I'm not a release maintainer. I don't have permission to merge commits to release branches. |
Ahh okay, in that case I am guessing @tru might be able to help us out. |
…gInterpreter for wasm (llvm#113446) While building llvm (clang, lld) for wasm using emscripten (recipe hosted on emscripten-forge https://github.com/emscripten-forge/recipes/tree/main/recipes/recipes_emscripten/llvm) I ended up with this error ``` │ │ wasm-ld: error: ../../../../lib/libclangInterpreter.a(Wasm.cpp.o): undefined symbol: lld::wasm::link(llvm::ArrayRef<char const*>, llvm::raw_ostream&, llvm: │ │ :raw_ostream&, bool, bool) ``` This is due to the link function here https://github.com/llvm/llvm-project/blob/a4819bd46d8baebc3aaa8b38f78065de33593199/clang/lib/Interpreter/Wasm.cpp#L25-L30 This was added through this PR (llvm#86402) as an attempt to support running clang-repl and executing C++ code interactively inside a Javascript engine using WebAssembly when built with Emscripten. The definition for link is present in lldwasm and when building for the emscripten platform we should be linking against it. (cherry picked from commit 075581f)
