Combining these into a single block makes sense to me.
Also, perhaps instead of defined(__EMSCRIPTEN_PTHREADS__) || defined(__EMSCRIPTEN_WASM_WORKERS__) you can just use ifdef __EMSCRIPTEN_SHARED_MEMORY__ ? Or equivalently ifdef _REENDTRANT

Hmm well, I suppose this could now just read #ifdef __EMSCRIPTEN_SHARED_MEMORY__ everywhere without introducing a RETRY_SBRK define at all?

Ah, I had thought to keep it for the brevity (since EMSCRIPTEN_SHARED_MEMORY is kind of long), and maybe for future use. Anyway, changed to #ifdef __EMSCRIPTEN_SHARED_MEMORY__ as you suggested.

Ohh, good find there were missing shared paths. I think |
… use __EMSCRIPTEN_SHARED_MEMORY__ for shared pthread/wasm workers cases
|
Makes sense, changed to use #ifdef EMSCRIPTEN_SHARED_MEMORY . |
… remove redundant RETRY_SBRK

Great, thanks! |
