Hi, I'm a beginner user using LLVM, and I'm trying to create a new backend using CPU0 Tutorial as reference. I have two instructions for add: add and addi (this is a pseudo instruction, but imediate operations is not available in architecture). That is my idea: When the LLVM instruction selection find addi r3 = r2 + value must convert to this: - load r1, value - add r3 = r2 + r1 In
