    compiler: add optional tail-call support in wasm NCG · 8a81d9d9
    Cheng Shao authored
    When the `-mtail-call` clang flag is passed at configure time, wasm
    tail-call extension is enabled, and the wasm NCG will emit
    `return_call`/`return_call_indirect` instructions to take advantage of
    it and avoid the `StgRun` trampoline overhead.
    Closes #22461.
