Z80asm appear to have bugs with regard to compliation of some undocumented IXL and IXH opcodes:

ADD, ADC, SUB, SBC, AND, XOR, OR, CP (DD/FD x4/x5/xC/xD , x=8..B) - wrong opcode produced

INC/DEC IXl, IXh, (DD/FD 24, 25, 2C, 2D) - refused to assemble

LD A,IXh, IXl, IYh, IYl (DD/FD 4C 4D) - refused to assemble
