The 32-bit immediate in 64-bit instructions is sign-extended, thus 48-F7-C1-80-80-80-80 is an opcode for "test rcx,0FFFFFFFF80808080h" (or "test rcx,-7F7F7F80h"), not for "test,rcx,80808080h".

I'm considering removing it, as the FAQs on this board tend to be better developing.

well, but seems nobody reads those...
having faq on board is imho too unstandard for most users. also it's better to have all Qs and As in one file, not to need to load thread for every problem and read all crap there |

So we can write a true FAQ here instead of just collection of links.

Perhaps it should be just rewritten from scratch. The "Important threads" has alteady taken the role of holding the links.
