[LLVMdev] Assertion failed after my storeRegToStackSlot/loadFromStackSlot
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, get(Z80::LD8xmr))
.addFrameIndex(FrameIndex).addImm(1)
.addReg(SrcReg, getKillRegState(isKill), Z80::subreg_hi);
After this store I catch assertion failed: "Instruction not found in
