I forgot to mention that unix (macos/linux) already have the mold linker which is fast and (production ready?) The only issue is with Windows in dev mode (edit-build-run cycles) I want to improve that cycle dev experience. Currently it takes 10s to link some large project with Rust on WIndows with lld. on Linux it takes 1-3s So it doesn't need to be military tested grade because it's just for faster development cycles

The struggle on windows is with debug information, and it may just get worse. Not even Microsoft have a clear understanding of the pdb format and the debug info for windows executable since the designers have long quit

Brother there is lld Linking in clang right , well as far i came to know u can use mold :) in windows . Basically you need to make it from scratch git clone https://github.com/rui314/mold.git cd mold Build mold from here :) cmake -B build -DCMAKE_BUILD_TYPE=Release cmake --build build Give its path in sys variables Just use the linker mate ;) , i mean by replacing the default linker of gcc and clang offcourse :P Now whenever you run the command to compile the program like gcc or clang , as you have modified its linker already so it will use mold liker now 🙂

Well mold is the fastest offcourse so i thought 🙂, why not getting the fastest in the pocket already, like why to build a new one 🥹 i mena if you want to grab, knowledge and experience thats great 👍🏻 or might you will create a new type of linker which is more faster than mold 🗿 OP bruh

Sadly mold supports only Windows. If there was fast linker for Windows I wouldn't consider write new one

The hard part will not be making it work. The hard part will be 1) compliance to a big standard with a lot of legacy 2) maintaining it 3) security (regulations!) So if it's a toy project to learn how to link objects together, you should count a few weeks. If its a serious project, you are best advised to contribute your improvements to gnu/ld, for example
