Hi,
Trying to test my Emscripten project with Asyncify, I recompiled it with
tot-upstream, with the same whitelist, but this is failing:
Part 1) Handling function names that change (work-around)
I read that using function prefixes worked as limited wildcard but that doesn't
seem to be the case - did I do something wrong?
-s ASYNCIFY_WHITELIST='["__pyx_pf_5renpy_2gl_6gldraw_6GLDraw_"...'
warning: Asyncify whitelist contained a non-existing function name:
__pyx_pf_5renpy_2gl_6gldraw_6GLDraw_ ($__pyx_pf_5renpy_2gl_6gldraw_6GLDraw_)
Also llvm-nm doesn't seem to support listing WASM.
I managed to find the function through emcc ... -o fat.llvm && llvm-nm fat.llvm
:
003832c5 t __pyx_pf_5renpy_2gl_6gldraw_6GLDraw_28draw_screen
Part 2) Run-time failure
With the updated WHITELIST, I got the dreaded:

Not sure if all the "emu$" and "fastfunction" are properly handled :/
Any clue?
Cheers!
