    [wasm] Support exceptions between interpreter frames. · 5b8c7f84
    Michael Starzinger authored
    This adds support for handling exceptions between different frames of
    one single interpreter activation. Frames are dropped until a local
    handler is found. If none is found in the current activation then we
    delegate to the existing stack unwinding mechanism to deal with multiple
    activations interspersed with non-interpreter stack frames on the actual
    machine stack.
