An Elf Odissey! #dreamos64 I recently added support for basic ELFs in my hobby #kernel but, it required me to dig into some very obscure issues caused by some changes in llvm and their linker.
Basically the introduction of large sections in #llvm broke the grub image, and caused more problems to my kernel.
I posted all the details of my debug process in my free #kofi post here: https://ko-fi.com/post/Finally-Dreamos64-is-officially-running-an-ELF-Exe-B0B41AYZW0
