Okay, so where should I send questions for WebAssembly? Is it this mailing list or a different one? I want to ask about how to compile WebAssembly modules with Clang directly, without Emscripten, for situations like what I have currently where I have a problem with generating WebAssembly and/or JavaScript glue code (I have a problem with the gen_struct_info stuff; I asked on the Emscripten

Apologies if there is a better forum for these questions. Please redirect me if so. I’ve been using the clang/wasm-ld tools to experiment with some basic examples, and there’s a couple things I’m wrestling with. 1) How to denote a function as the “start” function (https://webassembly.github.io/spec/core/binary/modules.html#start-section) 2) How to avoid the defaulted __heap_base global. I’ve

Has anyone attempted to compile R (probably without any OS bindings) to WebAssembly / Emscripten? If so, how far did you get? (would be crazy awesome if you could get all the way to a ggplot bitmap output). If not, is this a waste of time or is there some daylight to doing this? [[alternative HTML version deleted]]

wasm-ld is currently unable to link a shared wasm library (generated with `wasm-ld --shared`) with .o files and produce a working executable. I'm curious if there's a fundamental reason for this, or is this simply something that wasn't needed and could be implemented if needed. I think this could be done by - Resolving "GOT.mem" and "GOT.func" imports and

Hi xiph, I'm trying to compile libopus from git.xiph.org/opus.git with emscripten. The regular: $ emconfigure ./configure --enable-fixed-point $ emmake make gets me quite far, but it hangs on the use of __malloc_hook in the tests: tests/test_opus_api.c:1776:16: error: use of undeclared identifier '__malloc_hook'; did you mean 'malloc_hook'? orig_malloc=__malloc_hook;

Hi there, We are interested in adopting Opus into our web based application for speech recording. I'm wondering if there is a plan to port Opus encoder and decoder to Javascript using Emscripten in the near future?

Hi llvmers, As you may know, work has been progressing on the experimental WebAssembly backend in llvm. However, there is currently not a good linking story. Most the of existing linking strategies (i.e. those in the emscripten toolchain) involve bitcode linking and whole program compilation at link time. To improve this situation I've been working on adding a wasm backend for lld. My

Hi, Sorry if you've seen this message before on llvm.discourse.group or elsewhere -- I've been trying to get to the bottom of this for a while now and asked about this in a few different platforms before. I'm currently trying to debug a bug in a LLVM-generated Wasm code. The bug could be in the code that generates LLVM (rustc) or in the LLVM, I'm not sure yet. LLVM IR and Wasm

Hi I'm having a problem compiling opus-tools-0.1.7. Version opus-tools-0.1.6 seems to compile OK. I've tried with opus-1.0.3 and opus-1.1-beta. The errors are like this:- "undefined reference to `sqrtf'" etc. This OS is Peppermint Three, similar to Ubuntu 12.04. It uses:- gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Google says it's maybe something to do

Hi, We are able to reproduce the issue with the 1.1 opus_demo (sample file). We captured the frames in our server just before the opus_decode and fed the file to opus_demo (1.1) and it is crashing. Same file is tested with 1.1.1 and it is fine. So this is in line with our server testing observation and I think here we can conclude that the 1.1 library is crashing while handling a specific mode

As I recall, the major blocker is that R links against a number of other things (notably BLAS, pcre, etc) so while technically possible (?) I suppose, the universe of things you'd have to compile over and then get working is much larger than just the R internals. I think most people who consider this (including me years ago, as well as the poster of Gabor's message to rdevel) hit that

Can you link to docs about the wasm object format? (both relocatable and executable) Also, traditional object file linkers are primarily concerned with concatenating binary blobs with small amount of patching of said binary blobs based on computed virtual (memory) addresses. Or perhaps to put it another way, what traditional object file linkers do is construct program images meant to be mapped

Hi everyone, I wanted to mention a project using LLVM: Emscripten. Emscripten is an open source LLVM to JavaScript compiler, http://emscripten.org https://github.com/kripken/emscripten/ There are various demos linked to on the wiki (the first link), of various large C/C++ codebases compiled to JS and running on the web, like Python, Bullet, Poppler, etc. Emscripten is not a

Hi, There is no change in the compiler flags. I'm using as it is from the original code. No change in the Makefile and I believe it is using the floating point only by default. We are using 8k samples and mono so the commands is as follows. [root at MEDIA opus-1.1]# ./opus_demo -d 8000 1 opus_encoded_crash.opus opus_encoded_crash.pcm *And segmentation is as below..*. ............ Calling

Hi all, Over the past couple weeks, I've been putting together a JavaScript backend for LLVM. At this point, I believe I've got reasonable implementations for all the instructions, primitives and derived types. I haven't gotten around to most of the intrinsics but I thought it would be a good idea to start getting some feedback before going much further. If anyone has the time and
