    Use the following code:
    BuildOptions option = BuildOptions.None;
    PlayerSettings.WebGL.emscriptenArgs = "-s TOTAL_MEMORY=256MB -s --profiling-funcs";
    BuildPipeline.BuildPlayer(GetScenePaths(), dst, BuildTarget.WebGL, option);

    Before 2021, "--profiling-funcs" would keep original function name in wasm. But it doesn't work now，functions in wasm file looks like this:
    (func $f398 (type $t4) (param $p0 i32) (result i32)
    (local $l1 i32) (local $l2 i32) (local $l3 i32)
    local.get $p0
    call $f716
    block $B0 (result i32)
    block $B1 (result i32)
    local.get $p0
    i32.load offset=48
    if $I2 (result i32)
    local.get $p0
    i32.load8_u offset=186
    i32.const 8
    i32.and
    i32.const 3
    .....

    Hi,

    in Unity 2021.2 the option to keep original function names was added to the build settings. You can enable this by setting the "Debug Symbol Mode" to "Embedded" in the WebGL Player Settings or using the corresponding Scripting API: https://docs.unity3d.com/2021.2/Doc...nce/PlayerSettings.WebGL-debugSymbolMode.html
    Code (CSharp):
    1. PlayerSettings.WebGL.debugSymbolMode = WebGLDebugSymbolMode.Embedded;
    2.  
    This has the same effect as "--profiling-funcs".

    Thank you for this information, very helpful for us.
    But we still have related issue:
    If you choose External, it will cause compilation errors. Issue has been submitted before, but it has not been fixed for a long time. Our release version hopes to use external because it can reduce the code size.

    How we could set other option such as 
    MODULARIZE
    ?
