I did it. However I realized that it is not what I actually want, I will
write a new topic.

Re: regenerate wasm.js from preamble.js

2021-04-20 Thread Александр Гурьянов 
Yeah pushing emscripten of Unity to new version is a best solution either,
but I think it's impossible. They didn't change emscripten version for many
years, they use 1.38.11. I don't know why, maybe there is some internal
problem, but seems it's not into their priority. They  still use js2wasm to
generate WebAssembly.

I tried to update it manually by replacing emscripten, and hook into build
scripts, however they also uses *.bc files to link into binary. As answered
before, it's not possible to use *.bc files from older version of
emscripten with newer emscripten.

So, I see back porting wasm-split is only solution, btw I hope it will not
be super hard. I did similar stuff with js split. I use wasm file from
unity and split out some functions into js, now I just want to improve my
technology with wasm-split.

Re: regenerate wasm.js from preamble.js

2021-04-20 Thread 'Sam Clegg' via emscripten-discuss 
SPLIT_MODULE is currently experimental, with limited testing.   Trying to
backport it to an older version of emscripten, while not impossible, is
likely to result in many challenges, and is not really a use case that we
want to have to support.   It might just work.. but you will likely need to
get down in the weeds to fix any issues that come up.   Your energy may be
better spent trying to push unity to upgrade the version of emscripten they
support.

cheers,
sam

Re: regenerate wasm.js from preamble.js

2021-04-20 Thread Alon Zakai 
There is an experimental --post-link option to create a JS file for a given
linked wasm file. However it isn't aware of SPLIT_MODULE so I am not sure
if it will work here.

regenerate wasm.js from preamble.js

2021-04-20 Thread Александр Гурьянов 
Hi. I am trying to use SPLIT_MODULE with Unity. However unity shipped with
old emscripten that does not know how to deal with SPLIT_MODULE. I
successfully spitted wasm file with wasm-split, but I can't run it because
.js file can't load it.

Is it possible to regenerate .js file for given wasm, wasm.deferred file?
Or if it is not possible, what I should define for correct work of
SPLIT_MODULE? Currently I even can't start main module, had this error:


index.js:1 3943ms |  ERR! RangeError: offset is out of bounds

http://localhost:3000/dev/web/debug/gamepix-loader.js:6586:98),
