Are those instructions already in current snap build? I was going to try the 64bit build today. But after I upgraded current 32bit 6848 build from 6720 build (of Aug 6), I found my Z80 program not working normally. Any special changes recently? Both --oldralloc and normal command line "-mz80 -c --std-c99 --codeseg CODE" have the same problem.
