--- Comment #10 from Vadim Girlin ptpzz@yandex.ru --- I looked a bit more into it and AFAICS it's not just a single wrong bit, looks like r700 alu encoding is used for all r600 chips with llvm backend currently(In reply to comment #9)
As mentioned by Vadim on IRC: it seems many instructions in bytecode generated for RS880 have (incorrect) OMOD = 2, that is, ALU WORD1 bit 7 is set where it shouldn't be set
