llvm-node's Introduction

llvm-node

Node Bindings for LLVM. The API is mostly identical to the one of LLVM (when possible and not to cumbersom). All supported methods with their signatures are listed in the TypeScript definition file.

Getting Started

Install the packages using npm or yarn.

npm install --save llvm-node

Require llvm-node and you're good to go

import * as llvm from "llvm-node";
// or
const llvm = require("llvm-node");

const context = new llvm.LLVMContext();
const module = new llvm.Module("test", context);

const intType = llvm.Type.getInt32Ty(context);
const initializer = llvm.ConstantInt.get(context, 0);
const globalVariable = new llvm.GlobalVariable(module, intType, true, llvm.LinkageTypes.InternalLinkage, initializer);

const ll = module.print(); // prints IR
llvm.writeBitcodeToFile(module, biteCodeFileName); // Writes file to disk

Custom LLVM Installation

You can use the npm configuration options to set the path to the LLVM cmake directory. This is needed if you don't want to use the system default LLVM installation --- e.g. when you want to compile againt the latest dev version.

To change the LLVM version use:

npm config set cmake_LLVM_DIR $(path-to-llvm/bin/llvm-config --cmakedir)

If you want to change the value just for a single project use an .npmrc file in your project.

Debug Build

If you want to use Value.dump or Module.dump you need to use the debug build of the library (and, as well, of LLVM). In this case, run node-gyp build --debug or if using npm install run npm_config_DEBUG=true npm install llvm-node.

There variables can also be set using npm set:

npm config set [--global] DEBUG True

Develop with VS-Code

Install the C++ Extension
Install the Cmake Tools Extension
Configure the LLVM directory in the user settings by adding the following entry

"cmake.configureSettings": {
    "LLVM_DIR": "/usr/local/Cellar/llvm/7.0.0/lib/cmake/llvm" // Output of llvm-config --cmakedir
}

Run the CMake:Configure Command in Visual Studio Code
Run yarn configure from the command line
Run CMake:Build command in Visual Studio Code

llvm-node's Issues

Build issues with Node v12

Not sure what is causing this but looks like there are some build issues arising when building for node v12 as have cropped up in CI:

error: no matching function for call to ‘v8::Value::ToString()’
     llvm::DataLayout layout { ToString(info[0]->ToString()) };
                                                          ^
note: candidates are:
In file included from ...

layout.cc:5:
v8::MaybeLocal<v8::String> v8::Value::ToString(v8::Local<v8::Context>) const
   V8_WARN_UNUSED_RESULT MaybeLocal<String> ToString(
                                            ^
note:   candidate expects 1 argument, 0 provided

This only started happening with node v12 so I am guessing v8 api changed? Few other v12 errors I am also seeing in v12 also probably related to API changes: https://travis-ci.org/vsl-lang/VSL/jobs/525749327#L502

Lack of support for IntToPtr

This currently no way to convent a int back to a pointer!
https://llvm.org/docs/LangRef.html#inttoptr-to-instruction

Creating ConstantInts of very large numbers

I was recently implementing an algorithm that used a very large number 0xdf900294d8f554a5 in my language which compiles with llvm-node however I noticed an unusual issue is that JS cannot accurately represent such large numbers so the outputted LLVM contains an inaccurate number too. First thought was a .get() that takes a string and is parsed in C++ as a uint64 and then passed to LLVM could help solve this issue.

Missing nan.h

Contribution Guidelines

It seems I will be needing to add more stuff to this for my personal use. Instead of forking the library and including it privately, I'd like to do it properly and send pull requests that can be merged to the main repository.

I can just go and hack some stuff but if there were some guidelines that would prevent me shooting in my foot, it'd be much easier. For instance, this can be an example of one such case.

Type.getHalfTy() is missing.

There seems to be no way to create Half (16 bit float) types. There is a way in the LLVM api.

Type.getHalfTy(context) is the API I propose.

error: no member named 'getTypeByName' in 'llvm::Module'

This happens when I try to install lllvm-node via yarn on Termux. Possibly because I'm using LLVM 12 which is incompatible with llvm-node (contributions probably can make it compatible with llvm-node)

Can't found LLVM API: GetElementPtrInst

I want declare a number array and give it a value.

I can do this with clang, and the corresponding IR is

int a[3];
a[0] = 1;

%1 = alloca i32, align 4
%2 = alloca [3 x i32], align 4
store i32 0, i32* %1, align 4
%3 = getelementptr inbounds [3 x i32], [3 x i32]* %2, i64 0, i64 0
store i32 1, i32* %3, align 4

But don't know how to implement it in llvm-node , because I cant' found getelementptr api in llvm-node

Cannot find Builder.createUnreachable

Hello,

Builder.createUnreachable seems missing. Sometimes this function may be quite useful, for example, building a trap basic block, where we do not want a terminator branching.

Thanks

Can't find Function.eraseFromParent()

I'm currently working through the LLVM Kaleidoscope tutorial - in chapter 3 (https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/LangImpl03.html) there's reference to an eraseFromParent() method on Function, but it doesn't show up in the typeScript definitions file.

How to create parameters for function?

I'm having trouble defining function arguments, how can I create the formal parameter list and assign it to a function?

Doubts about the `ConstantExpr` object

Hi, MichaReiser!

I want create a global string, and I can do this right now by such codes

const v = llvm.ConstantDataArray.getString(context, "Hello");
const r = new llvm.GlobalVariable(module, v.type, false, llvm.LinkageTypes.ExternalLinkage, v, name);

But I got some question, The generated IR is

@s = global [6 x i8] c"Hello\00"

See, the @s is an array.

When I declare a global string in clang, The generated IR is

@.str = private unnamed_addr constant [6 x i8] c"world\00", align 1
@s = global i8* getelementptr inbounds ([6 x i8], [6 x i8]* @.str, i32 0, i32 0), align 8

the @s is an i8*

I think clang has done one more thing by

ConstantExpr::getBitCast(v, i8->getPointerTo())

I want my global string's type is i8* so I can pass in to system's function stdio::printf as an argument. But I don't known how can I do it because I can't find the ConstantExpr in llvm-node.

Installation failed

Installation fails on Ubuntu 18.04 when CMake begins linking process. Any ideas? This is extremely frustrating.

Migrate to N-API

Plan migration to N-API. See this blog post for details.

no member named 'getTypeByName' in 'llvm::Module'

When building with LLVM 12, I get this error:

node_modules/llvm-node/src/ir/module.cc:139:38: error: no member named 'getTypeByName' in 'llvm::Module'
    llvm::StructType* type = module->getTypeByName(name);

`Module::getTypeByName`

LLVM has a Module::getTypeByName(StringRef) which will return a type in the module with a given name. Could this be added or is there a recommended alternative for this function?

Use explicit declarations over using NAN Macros

The Nan documentation suggests to declare methods explicitly over using the Nan Macros.

void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
  ...
}

instead of

NAN_METHOD(MethodName {
  ...
}

The explicit declaration is suggested not only for JS method implementations but also for getters, setters...

The more explicit way has the advantage that many IDEs provide better IntelliSense and is generally either understood by humble humans as well.

It is, therefore, probably advisable to migrate the existing code base to use explicit method declarations.

StoreInst type problem (ConstantFP)

I'm trying to create a store instruction that will store a float on a float allocation (logical).

However, I'm running into the problem that when I access ConstantFP.get(), I have no way of specifying the type I want for the value. So ConstantFP.get() accepts LLVMContext and a number in that order.

But in the LLVM documentation this is possible:

Has this method not been implemented? The other way I tried was changing the type property of the returned value manually, but it shouldn't be like this... (have not verified working).

This is what is generated from my current code:

define void @main() {
  %pi = alloca float
  store double 3.140000e+00, float* %pi
  ret void
}

from:

...
const myFloat = parseFloat( ... )
ConstantFP.get(<context>, myFloat); // I want a float, creates a double instead.
...

The ConstantInt class' get() method looks more flexible, as it allows to specify the size, etc.

Expose JIT functions.

An important use case for llvm-node is to implement small toy languages, thus JIT becomes a necessary function. Not all use requires writing a bitcode to file. Is exposing JIT functions in the pipeline?

How to properly call a function (params) with LLVM-Node.

I've looked through the tests and I've not found anything that details how to call a function with parameters in LLVM-Node. Do I just use an array? Is it not possible?

No way to do builder.createStore() for float or half constants

In order to be able to work with non double floating point constants, we need the mappings for APFloat and ConstantFP::get(Type* Ty, const APFloat &V) APIs.

http://llvm.org/doxygen/classllvm_1_1APFloat.html
http://llvm.org/doxygen/classllvm_1_1ConstantFP.html#ac698873f7b353f3a37cb8577b74acf72

Need help for `InlineAsm`

// hope you are not bored with me :)

In simple terms, I am implementing a system call, which will requires InlineAsm.

I studied the code that implements the system call in c language and its IR:

static inline long
__internal_syscall(long n, long _a0, long _a1, long _a2, long _a3, long _a4, long _a5)
{
    register long a0 asm("a0") = _a0;
    register long a1 asm("a1") = _a1;
    register long a2 asm("a2") = _a2;
    register long a3 asm("a3") = _a3;
    register long a4 asm("a4") = _a4;
    register long a5 asm("a5") = _a5;
    register long syscall_id asm("a7") = n;
    asm volatile ("scall": "+r"(a0) : "r"(a1), "r"(a2), "r"(a3), "r"(a4), "r"(a5), "r"(syscall_id));
    return a0;
}

which results the IR code:

; Function Attrs: noinline nounwind optnone
define internal i64 @__internal_syscall(i64 %n, i64 %_a0, i64 %_a1, i64 %_a2, i64 %_a3, i64 %_a4, i64 %_a5) #0 {
entry:
  ......
  %14 = call i64 asm sideeffect "scall", "={x10},{x11},{x12},{x13},{x14},{x15},{x17},0"(i64 %8, i64 %9, i64 %10, i64 %11, i64 %12, i64 %13, i64 %7) #1, !srcloc !2
  .....
}

I can implement this with the c library of llvm:

llvm::InlineAsm *IA =
llvm::InlineAsm::get(FTy, AsmString, Constraints, HasSideEffect,
                         /* IsAlignStack */ false, AsmDialect);
llvm::CallInst *Result = Builder.CreateCall(IA, Args);

But I can't find the InlineAsm in llvm node, I don't know how to implement this function. Thanks.

Any ideas? I'm not familiar enough with the ecosystem to debug the llvm-node/llvm boundary.

In the meantime, I'm going to try compiling against an older version of LLVM and report back

Is it some problems about macos system?

thanks for the response.

Requirements?

I am using windows 10. What do I need to do to use llvm-node? I tried installing LLVM-13.0.1-win64.exe. Then when I installed llvm-node, I got this error:

CMake Error at CMakeLists.txt:6 (find_package):
│   Could not find a package configuration file provided by "LLVM" with any of
│   the following names:
│     LLVMConfig.cmake
│     llvm-config.cmake
│   Add the installation prefix of "LLVM" to CMAKE_PREFIX_PATH or set
│   "LLVM_DIR" to a directory containing one of the above files.  If "LLVM"
│   provides a separate development package or SDK, be sure it has been
│   installed.

Do I need to download llvm source code?

DIBuilder class

LLVM has a LLVM::DIBuilder which provides tools for creating debug information.

I'll attempt to make a PR for this in the upcoming weeks.
