Overview

llvm-bindings

LLVM bindings for Node.js/JavaScript/TypeScript

Supported OS

macOS
Ubuntu
Windows

Supported LLVM methods

listed in the TypeScript definition file.

Install

Install on macOS

# install cmake and llvm by homebrew
brew install cmake llvm

# install llvm-bindings by npm
npm install llvm-bindings

Install on Ubuntu

#install llvm by installation script
wget https://apt.llvm.org/llvm.sh
sudo chmod +x llvm.sh
sudo ./llvm.sh

# install cmake by apt-get
sudo apt-get install cmake

# install llvm-bindings by npm
npm install llvm-bindings

Usage

// If you have configured ES module or TypeScript, you can replace the next line with `import llvm from 'llvm-bindings';`
const llvm = require('llvm-bindings');

const context = new llvm.LLVMContext();
const mod = new llvm.Module('demo', context);
const builder = new llvm.IRBuilder(context);

const returnType = builder.getInt32Ty();
const paramTypes = [builder.getInt32Ty(), builder.getInt32Ty()];
const functionType = llvm.FunctionType.get(returnType, paramTypes, false);
const func = llvm.Function.Create(functionType, llvm.Function.LinkageTypes.ExternalLinkage, 'add', mod);

const entryBB = llvm.BasicBlock.Create(context, 'entry', func);
builder.SetInsertionPoint(entryBB);

const a = func.getArg(0);
const b = func.getArg(1);
const result = builder.CreateAdd(a, b);
builder.CreateRet(result);

if (!llvm.verifyFunction(func) && !llvm.verifyModule(mod)) {
    mod.print();
}

You cannot declare a variable or constant named module in top level, because module is a built-in object in Node.js.

Note

Due to the limitation of node-addon-api, this project has not implemented inheritance yet, so calling the method of superclass from subclass object will report an error. Please see #1 for details.

Compatibility

Comments

Unable to run on Monterey on M1 MacBook Pro
OS version: Mac OS 12.0.1 M1 MacBook Pro

Node.js version: 17.01

LLVM version: 13

Was able to successfully install the npm module on a brand new M1 MacBook but run into runtime errors when trying to launch:

Error: dlopen(node_modules/llvm-bindings/build/Release/llvm-bindings.node, 0x0001): symbol not found in flat namespace '_LLVMInitializeAArch64AsmParser

Expected behavior

Everything works fine on an Intel Mac. I am assuming that there are some issues with M1 Mac's being Arm?

[Bug] CreateAlloca causes segmentation fault
Your environment

OS version: MacOS monterey

Node.js version: 17.6.0

LLVM version: 13

Describe the bug

Essentially, if I pass an IRBuilder around a few functions as an argument, (I haven't tested without doing this but I strongly assume that nothing would change if I used it in its original function) CreateAlloca causes a segmentation fault. It used to work and I haven't changed anything about how I use it but it still doesn't work. I have tried manually declaring all of the values so I am sure there is nothing wrong with them. This is how I am using it:

builder.CreateAlloca(builder.getInt64Ty(), null, name)

All I get is a segmentation fault. I have run SetInsertPoint if you are wondering.

Expected behavior

No segmentation fault, a variable to be created

[Feature] There seems to be no bindings for "ConstantArray"

Which LLVM APIs do you want llvm-bindings to provide There seems to be no bindings for "ConstantArray", which is quite an important datatype since it's needed for most string implementations. Could it be added to the bindings or is there some issue preventing that?

[Bug] CreateGEP causes segmentation fault
Your environment

OS version: macOS Monterey 12.1

Node.js version: 17.1.0

LLVM version: 13.0.1

Describe the bug

I'm trying to create a getelementptr statement using the bindings, but I get a segmentation fault when I run the program.

const printConst = builder.CreateGlobalString( printArg.text, `${VARIABLE_STRING_PREFIX}.${VARIABLE_COUNT_GLOBAL}`, 0, module ); builder.CreateGEP(printConst.getType(), printConst, [ builder.getInt64(0), builder.getInt64(0), ]);

Expected behavior

It should produce a statement similar to this:

%cast210 = getelementptr [13 x i8],[13 x i8]* @.str, i64 0, i64 0

Memory intrinsics not working

It seems that trying to access any of the memory intrinsic functions will cause a seg fault e.g.:

const memcpy = llvm.Intrinsic.getDeclaration(module, llvm.Intrinsic.memmove)

The intrinsic function highlighted in the test folder (debugtrap) does work but none of the memory related ones seem to work (memcpy, memcpy_inline, memmove, etc).

Also, thank you for putting this library together, its great to finally have access to the larger feature set of llvm through node!

Release notes

Sourced from cmake-js's releases.

v7.0.0

This is a breaking change and will likely require some small changes to your cmake config to keep your project building.

Summary

A lot of work has gone into this release, to try and make the general usage of the library smoother. It has better support for building modules with node-api. The on disk footprint of the library is much smaller than before, with various dependencies removed, or updated.

Upgrading

We recommend having the following at the top of your cmake file, before the project(...) definition.

cmake_minimum_required(VERSION 3.15) cmake_policy(SET CMP0091 NEW) cmake_policy(SET CMP0042 NEW)

This will force MSVC to do a MT build, so if you were doing that another way, it should be possible to remove that. If you need to keep it building as MD, you can add set(CMAKE_MSVC_RUNTIME_LIBRARY "MultiThreaded$<$<CONFIG:Debug>:Debug>DLL") in your cmake file.

If you are using node-api, make sure that your package.json has the following, but with the correct NAPI_VERSION filled in. We use this to autodetect that your module is building with node-api.

"binary": { "napi_versions": [7] },

You should also add the following to the bottom of your cmake file. This lets us avoid downloading the full nodejs headers, and lets us use bundle a much more lightweight copy instead

if(MSVC AND CMAKE_JS_NODELIB_DEF AND CMAKE_JS_NODELIB_TARGET) # Generate node.lib execute_process(COMMAND ${CMAKE_AR} /def:${CMAKE_JS_NODELIB_DEF} /out:${CMAKE_JS_NODELIB_TARGET} ${CMAKE_STATIC_LINKER_FLAGS}) endif()

If you have something like:

execute_process(COMMAND node -p "require('node-addon-api').include" WORKING_DIRECTORY ${CMAKE_SOURCE_DIR} OUTPUT_VARIABLE NODE_ADDON_API_DIR ) string(REPLACE "\n" "" NODE_ADDON_API_DIR ${NODE_ADDON_API_DIR}) string(REPLACE "\"" "" NODE_ADDON_API_DIR ${NODE_ADDON_API_DIR}) target_include_directories(${PROJECT_NAME} PRIVATE ${NODE_ADDON_API_DIR})

in your file, it is no longer needed. We will inject the correct include paths for you, similar to what is done for nan.

That should be everything.
If we missed something in these steps, or if you are having problems getting your module building again, let us know in an issue.
