...table sources to a minimum of two simple base-instructions and attached these for reproduction of the problem (not sure if the attachment gets through). The table generation is done with: llvm-tblgen -gen-dag-isel -I=<path-to-llvm-include> -o=out.inc Z80.td The first instruction in Z80InstrInfo.td is a unary instruction, that does a rotate left of a byte in memory, resulting in the leftmost bit being placed in the Carry flag - and changing the memory contents at the pointer's address (in Z80: "RLC (HL)", I expect). The table generation completes without errors with just t...
