asm-lsp provides hovering and autocompletion for assembly files written in the GAS/NASM or GO assembly flavors. It supports assembly files for the x86 or x86_64 instruction sets. This tool can serve as reference when reading the assembly output of a program. This way you can query what each command exactly does and deliberate about whether the compiler is producing the desired output or whether you have to tweak your code for optimisation.
