    [wasm] Add test for creating 10k modules in one process · 87287908
    Clemens Hammacher authored
    With --wasm-far-jump-table, it will be possible to create 10k (and
    more) modules in one process. So far, we hit the virtual address space
    limit around 1k modules, because each module makes a reservation of
    {kMaxWasmCodeMemory} upfront. After this change, each module will only
    reserve the estimated needed code size (if --wasm-far-jump-table is
    set).
    
    The test is carefully optimized to not execute too much code in the
    loop, so it can still run in simulators in reasonable time. Note that
    the time for actually compiling the module is spent in C++, which is
    fast in simulator builds.
