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]]

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

Cause llvm-libc are in early stage, and we can easily catch up the support with linux. After we add wasi support in llvm-lic, we can easily get a usable llvm-libc across different platform such as linux/windows/macos/android. don't know if iOS is a target, but these target are very much enough -- 此致 礼 罗勇刚 Yours sincerely, Yonggang Luo -------------- next part -------------- An

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

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

I think most people are using ninja to do the build. You can still use the Visual Studio generator for the IDE experience while doing build from ninja. I know there are a couple of people who build from inside of Visual Studio, but it's a pretty small number, and I don't think they are targeting WebAssembly.

@Jonathan Goodwin: Do I have to use a flag to tell it where the LLVM include files are? And would it be easier to do that in the CMake GUI? Please tell me how you had it find the include files if that may help me. ________________________________ From: Jonathan Goodwin <jondgoodwin at gmail.com> Sent: Wednesday, November 28, 2018 6:24 AM To: zturner at google.com Cc: Osman Zakir; llvm-dev

Somehow I wish not all parts of a libc but parts that can be provided without a JavaScript wrapper for .wasm can be provided from llvm's libc (leaving a stab implementation for the rest like file system). I've put together a minimal libc on [1] so using a 26kb .wasm binary file one can decode both PNG and JPG using this [2] simple to integrate JavaScript code, can be easily ported in other

Hi Sam, First, I want to know the symbol resolution semantics. I can imagine that that is set in stone yet, but just that you guys are still discussing what would be the best semantics or file format for the linkable wasm object file. I think by knowing more about the format and semantics, we can give you guys valuable feedback, as we've been actively working on the linker for a few years

Yeah, I don't think that matters. It did set the toolset architecture to x64. You know, I attached those log files for a reason. ________________________________ From: Zachary Turner <zturner at google.com> Sent: Tuesday, November 27, 2018 4:27 AM To: Osman Zakir Cc: llvm-dev at lists.llvm.org Subject: Re: [llvm-dev] Have LLD and Clang in their correct locations, but still can't

Hello all, WebAssembly [0] its a new virtual ISA being designed to efficiently run compiled code in web browsers and other things, starting with C/C++, and eventually many other languages [1]. WebAssembly distinguishes itself from other virtual ISAs with optimizations to reduce download size and decode time, strong portability and predictability invariants (for example, the base has no undefined

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

I get the following message when cross compiling Opus 1.2.1 for android with clang in a standalone build.   CC       src/opus_decoder.lo src/opus_decoder.c:37:10: warning: You appear to be compiling without optimization, if so opus will be very slow.

I ran CMake on the command line with this command: " cmake .. -DCMAKE_INSTALL_PREFIX=../install_x64 -T host=x64 -G "Visual Studio 15 2017 Win64" -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly " And I have LLD and Clang where they should be. But I still couldn't generate project files. The path to the build and installation directories don't have spaces at all this

I'm using CMake version 3.12.3 on Windows 10 Home. I checked out LLVM, Clang, Clang extra tools, Compiler-RT, LLD, LibOMP, LIBCXX, and LIBCXXABI with SVN and am now trying to generate project files. But LLD, among some other things, wasn't found (even though put all of those in the documented directories inside the LLVM source tree). And a lot of the tests failed. I'm attaching the

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

I don't know what executable to point it to for SVN because, like I said before, I just right click where I want to check something out and click what I need in the context menu. So I need to know what executable to point it to. ________________________________ From: Osman Zakir <osmanzakir90 at hotmail.com> Sent: Thursday, November 29, 2018 11:06 PM To: Zachary Turner; llvm-dev at

Hello. Excuse me. Why CMakeLists.txt from llvm-3.9.1.src does not contain WebAssembly target? So, it is like set(LLVM_ALL_TARGETS AArch64 AMDGPU ARM BPF Hexagon Mips MSP430 NVPTX PowerPC Sparc SystemZ X86 XCore ) but not like set(LLVM_ALL_TARGETS AArch64 AMDGPU ARM BPF Hexagon Mips MSP430 NVPTX PowerPC Sparc SystemZ Webassembly X86
