Re: Regal GL

Finally, I integrate regal gl into emscripten. You should call RegalMakeCurrent((RegalSystemContext)1); to associate emscripten gl context with regal gl context. Like this: glutInit(, argv); glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); glutInitWindowPosition(0, 0);

Re: Progressive performance loss while execution of script

No, this bug affects only Safari browser (IOS 10). Where I can learn more about JS VM deopts? As I understand in emscripten we use typed array as HEAP, so we allocate this array on start and then use it (without grow/shrink). Why GC is relevant in this case? 2016-11-10 1:47 GMT+03:00 Alon Zakai

binaryen, wabt, webassemblyjs

Hi guys! I want to write some tool to analyze wasm files. My first target is to create tool like bloaty to analyze size of contribution of each function in resulting size. But bloatly is universal tool, I want to concentrate on wasm format and maybe create something like "code explorer" tool (like

emscripten + opengl on MacOs

Hi guys. I am not familar with MacOs, so maybe my question is really simple. I have a lot of projects based on OpenGL variations (GL1, ES, ES2). Emscripten have brilliant support for it. My main OS is linux that also provide fantastic capabilities to building OpenGL projects. Because of that

Re: Snapshotting runtime

Thanks for feedback. Now I am saving and restoring all wasm mutable globals. But seems it does not help, I still have unstable behaviour. I forgot to say that I use emterpeter too, can it produce additional problem for save/restore wasm state? вс, 12 мая 2019 г. в 22:31, Liam Wilson : > > A

Snapshotting runtime

Hi is it possible to make snapshot of runtime, serelize it to file and then restore runtime on other client. I understand that snapshotting have a lot of pitfalls. But for now I want to implement simpliest case. My target is wasm, main loop is executed by requestAnimation frame. So stack always

undefined symbol: PATH_FS after updating to latest incoming

Hi guys! Just updated to latest incoming (39158e5e344460d5c0a5da8913f87e4cb0db6e4a) and now have this error that does not exists on previous version: error: undefined symbol: PATH_FS warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0` Have no idea what is

Hi. You can replace it with -s WASM=0. That means to produce asm.js as output, if you set -s WASM=1 then output will be wasm. пт, 5 июл. 2019 г. в 08:57, juef : > > Greetings, > > I am trying to compile an old project from GitHub which uses emscripten, and > the makefile calls emcc with a -s

Memory is not large enough for static data

Hi. I am trying to set TOTAL_MEMORY to 32mb, but compiler told me: shared:ERROR: Memory is not large enough for static data (30099056) plus the stack (5242880), please increase TOTAL_MEMORY (33554432) to at least 35342960 Is there any way to find what and where this data located? Thanks --

Oz and symbols

HI. I used wasm-opt manually to optimize wasm binary. On last step I used Oz to finalize optimizations. My problem is that after Oz function indexes is changed and I can't get symbols map to restore function names. How I can map new function indexes to old one (from symbols file). In other words:
