Backport 075581f34035c01659cc883d0d69336c279ef0d5 Requested by: @aheejin >From 106bb2f7c208798a3af34c3ec72fbd65683c9293 Mon Sep 17 00:00:00 2001 From: Anutosh Bhat <87052487+anutosh...@users.noreply.github.com> Date: Fri, 25 Oct 2024 11:39:14 +0530 Subject: [PATCH] [clang-repl] Fix undefined lld::wasm::link symbol while building clangInterpreter for wasm (#113446) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 (https://github.com/llvm/llvm-project/pull/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.
