    [wasm] Change signature of memory_copy_wrapper · d20b023c
    Andreas Haas authored
    All other simple C functions take a pointer to a stack slot which
    contains the actual parameters, whereas the memory_copy_wrapper takes
    three parameters. This makes the code generation from Liftoff more
    difficult. This CL changes the signature of memory_copy_wrapper to match
    the signature of other simple C functions.
    
    As MemoryCopy and MemoryInit are already implemented with C calls, this
    change should not make a big difference in terms of performance. Simpler
    and smaller Liftoff code may have more effect on performance. If this
    assumption turns out wrong, we can change it in the future.
