[Hexagon] Failure to disassemble some new-value instructions
...newvalue producers
return MCDisassembler::Fail;
Where does the requirement come from? Maybe I overlooked it, but I do not see it in the Hexagon V5/V55 Programmer’s Reference Manual.
One instruction packet I have encountered in the wild that triggers this failure is:
10: e0 7e df 78 78df7ee0 { r0 = #-9
14: 01 40 91 91 91914001 r1 = memw(r17 + #0)
18: 10 e1 03 25 2503e110 if (cmp.gtu(r1.new, #1)) jump:t 0x30 }
Removing the requirement seems to work fine (see attached patch).
Cheers,
Ralf
