What builder do you guys use?

i am currently making a compiler. i already finished making parsing using the pest crate and i made some custom IR code. but i now need to make a builder. i know already how to create a custom builder, but making the custom IR took long enough, so i wanted to see if there's any cool crates to make my life easier for this. please suggest any crate you guys know, I'd love to see what options would i have.


Builder in what sense?

a builder for the compiler. meaning, something that takes in IR tokens as input, and for every IR token, it returns a String of the equivalent in another language. so for example, this c code:

int main() {return 0;}

could be turned into this IR:

<function> () -> int {<std::return>(int::0)} 

and then be compiled into assembly

section .text:
    global _start

    mov ebx 0
    mov eax 1
    syscall ; int 0x80, but simpler

or at least, this is the goal

So you want a compiler backend? Something like Cranelift?

yeah, that's exactly what i want. i just wanted to see the different options the community suggests

If you want to target WebAssembly, the wasm-encoder crate is one of the most popular, and it's maintained by The Bytecode Alliance so you know it'll be the most up to date.

I'd second the recommendation for cranelift as a good backend to target and contribute to.


If you want to work with LLVM specifically, take a look at inkwell.
