For my next #compiler project, I want to write the optimization passes myself, but I don't want to deal with generating machine code for multiple platforms. So tell me #programminglanguages #plt #pldev #compilers fedi, what is an IR that I can target that has a non-optimizing compiler to machine code and supports multiple platforms? This rules out most popular IR like LLVM, C, QBE, Cranelift etc.

In short, I want something that does only instruction selection, register allocation and codegen for multiple platforms. I don't need optimization, so I expect this thing to be really small and lightweight, unlike LLVM, GCC etc.
