    [wasm] Indirect calls without function table cause validation errors. · 3de52047
    ahaas authored
    The spec defines that indirect calls in WebAssembly code should cause a
    validation error if no function table exists.
    
    The CL contains the following changes:
    1) Throw a validation error for indirect calls if the function table
       not exist.
    2) Do not create TF nodes to throw a runtime error for indirect calls
       if the function table does not exist.
    3) Fix existing unit tests by creating a dummy function table.
    4) Add new a new test which tests that indirect calls without function
       table cause a validation error.
