s2wasm, what distinguishes --global-base from --allocate-stack ?
Hey there, I guess my question is pretty straight but: For s2wasm, what distinguishes --global-base from --allocate-stack ? I don't really understand the purpose of --allocate-stack (wasm has its own way to allocate variable on the stack with «set_local») and I guess it's something related to --global-base.

Re: -s EXPORTED_FUNCTIONS and -s ONLY_MY_CODE=1 -s WASM=1
Also, is it safe to think «-s WASM=1 -s SIDE MODULE=2» will stay maintained in future release? Should I move to the vanilla LLVM ?

-s EXPORTED_FUNCTIONS and -s ONLY_MY_CODE=1 -s WASM=1
Hello there :) Right now, -s EXPORTED_FUNCTIONS doesn't seem to work with Standalone webassembly (provided by -s ONLY_MY_CODE=1 -s WASM=1 ). The code exports a lot of functions and it makes the wasm output really big. Is there an available parameter for this ?

Binaryen and total size of «Heap» memory used when loading.
Hello everyone, Is there a «verbose» mode with bynaren that could tell us the size used in the shared memory with javascript ? Some hints in my wast file : (data (i32.const 16) "foo \00") (data (i32.const 32) "foo \00") With that information, I could define precisely where I can start to store custom data in my «WebAssembly.Memory» object.

Re: About vanilla wasm and emcc SIDE_MODULE
Thanks for your detailed answer, it's really helpful.

Re: About vanilla wasm and emcc SIDE_MODULE
Also, do you recommend the use of emscripten for "vanilla wasm" output or should I stick with the original LLVM distrib ? -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.

Re: About vanilla wasm and emcc SIDE_MODULE
Thanks for the detailed answer, I appreciate your help :) I have some questions about that: 1) Are the global destructors called ? 2) Also, "__post_instantiate" seems to allocate the stack but the Vanilla LLVM doesn't do that. Doesn't Wasm have its own default stack ? And more : 3) How can I use the WebAssembly.Table feature in my wasm output (from my c++ code) ? -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.

About vanilla wasm and emcc SIDE_MODULE
Hello there, Sorry for my approximate english. It is now possible to make a standalone WebAssembly file. I'm gladly to see that is possible now with Emscripten, thanks. I can now make my own HTML source content, with my own way to load the WebAssembly bytecode. But I don't understand why the "__post_instantiate" function is exported too ? The wiki at https://github.com/WebAssembly/tool-conventions/blob/master/DynamicLinking.md says it's about a dynamic link feature... but I feel that I just need a vanilla wasm file without such feature. It's how I compile my code currently : C:\dev\emscripten\emscripten\em++ -s ONLY_MY_CODE=1 -s WASM=1 -s SIDE_MODULE=2 -s DISABLE_EXCEPTION_CATCHING=1 -s AGGRESSIVE_VARIABLE_ELIMINATION=1 -s EXPORTED_FUNCTIONS="['_myfunc','_myfunc2']" -std=c++11 -g0 -O3 foo.cpp -o target.wasm Thanks, Jean -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
