Hi Dmitriy, As you've seen our current spill code assumes that spill/reloads are single instructions. I think the best way to work around this is to introduce load/store pseudo-instructions and expand these after register allocation. Cheers, Lang.

Hi All. I'm writing storeRegToStackSlot and loadFromStackSlot function for my Target. This Target can store/load one byte (not all word) from FrameIndex. If I need to store 16 bit register I will must to split it to two instruction like this: BuildMI(MBB, MI, dl, get(Z80::LD8xmr)) .addFrameIndex(FrameIndex).addImm(0) .addReg(SrcReg, 0, Z80::subreg_lo); BuildMI(MBB, MI, dl,
