Hi Matthias, Sorry for the late reply. Yes, you are correct, I do have optnone attribute on my function. I did pass -O0 to the tools. For your information, my invocations are as below: clang --target=mips-unknown-linux -mips32 test.c -emit-llvm -S llc -O0 -march=mips -mcpu=mips32 test.ll -o test.s Based on the generated .ll file, there is optnone attribute on the function, i

Hi, I am planning to expanding the pseudo instructions in XXXTargetLowering::EmitInstrWithCustomInserter(), and use temporary virtual registers as operands. If I use virtual registers, do I need to mark them as "early clobber"? I saw that sometimes they marked virtual register as "early clobber" in EmitInstrWithCustomInserter() in MIPS backend. What is the effect of marking a
