I think one solution would be to have another language that's a bit more abstract than ASM maybe with some variables and register spilling and some macros, so you can write ASM more easily. That language could be transpiled into ASM, but would need to be debugged as ASM as well then, so you still need to know assembler very well. I tried to do that a couple years ago with little success (readme and feature list missing, sorry but maybe you get the idea from the repo): https://github.com/NanoWar/FunkCompiler https://github.com/NanoWar/FunkCompiler
