Ever since mold relicensed from AGPL to MIT (as part of mold 2.0 release), the worldwide need for making another fast linker has been greatly reduced, so I wasn't expecting a project like this to appear. And definitely wasn't expecting it to already be 2x faster than mold in some cases. Will keep an eye on this project to see how it evolves, best of luck to the author.

Note that Mold has no interest in becoming incremental, so there is a big reason there for another linker to exist. I find it kind of embarrassing that MS' linker has been incremental by default for decades, yet there's no production ready incremental linker on Linux yet.

I'm pretty sure that's a typo, and "incremental" was meant to be included in that sentence.

I looked at this before, is it ready for production? I thought not based on the readme, so I'm still using mold. For those on macOS, Apple released a new linker about a year or two ago (which is why the mold author stopped working on their macOS version), and if you're using it with Rust, put this in your config.toml: [target.aarch64-apple-darwin] rustflags = [ "-C", "link-arg=-fuse-ld=/Applications/Xcode.app/Content…

No, the author is pretty clear that it shouldn't be used for production yet

Great, I'll keep a look out but will hold off on using it for now.

What would be refreshing would be a C/C++ compiler that did away with the intermediate step of linking and built the whole program as a unit. LTO doesn't even have to be a thing if the compiler can see the entire program in the first place. It would still have to save some build products so that incremental builds are possible, but not as object files, the compiler would need metadata to know of the origin and depend…

Maybe I'm holding it wrong, but mold isn't faster at all if you're using LTO, which you probably should be.

Yeah, if you're development process requires LTO you may be holding it wrong.... Specifically, if LTO is so important that you need to be using it during development, you likely have a very exceptional case, or you have some big architectural issues that are causing much larger performance regressions then they should be.

Being able to choose a middle ground between development/debug builds and production builds is becoming increasingly important. This is especially true when developing in the browser, when often something appears to be slow in development mode but is fine in production mode.

WebAssembly and lightweight MicroVMs are enabling FaaS with real time code generation but the build toolchain makes it less appealing, when you don't want it to take half a minute to build or to be slow.

Why so hostile? Have a break, go look at the clouds, they are beautiful today!

Yes, I missed a word. And I believe pretty much everybody else realized what I meant to say.

Feel free to point me in the direction of a production grade incremental compiler that can run on Linux, GNU or otherwise.

Agreed. Both fast and small are desirable for sandboxed (least authority) isomorphic (client and server) microservices with WebAssembly & related tech.
