On x64 the machine code 83 F9 FF is decoded as cmp ecx, FFFFFFFFFFFFFFFF which compares a 32-bit register with a 64-bit immediate. In spite that the immediate is sign-extended, if an unsigned format is preferred the correct code should be cmp ecx, FFFFFFFF.
83 F9 FF
cmp ecx, FFFFFFFFFFFFFFFF
cmp ecx, FFFFFFFF
How is this not reproduced??
You just pick an arbitrary x64 executable, open it with x96dbg, press Ctrl+E in the disassembly tab, enter 83 f9 ff then Click OK.
83 f9 ff
@lhmouse the not reproduced label means that I have not reproduced the issue yet. Obviously the creator of the issue (eg you) reproduced the issue but that's not very relevant to the issue management from my side.
Oh fair enough. The label is extremely misleading to me.
One more word: I didn't receive any notification about the action that someone (you) had added some labels. Would you please add a comment after it, letting people (me) know they must provide more information?
No, I did not require more information. The labels on issues are intended for developers, in general they are not relevant for the person reporting the issue.
