...copy instructions which are generated during register allocation and expanded post-RA but before the final stack size is known. I use register scavenger to search for a temporary integer GPR that is used during pseudo-expansion. This is what happens during pseudo-expansion: The following pseudo LoadAC $acc, FI // Pseudo load instructions. Load from FI to accumulator $acc. is expanded into this sequence: LW $reg, FI // load from FI to temporary GPR $reg MTLO $reg // copy $reg to register LO LW $reg, FI + 4 // load from FI+4 to GPR $reg MTHI $reg // copy $reg to regis...
