This is my list



Matrix = 1, -2, 3, -4, a, b, f, e, a, b, f, e


I want to order the columns in ascending order depending on the values on the first row. I Expect something like



-4, -2, 1, 3, f, e, f, e, a, b, a, b


I've tried the Sort function, but it just returns the initial value

    • Yes... in my personal code I changed the name because we must never use an upper-case letter to start the name of a variable, lest it conflict with internal definitions. Thanks. Solution amended.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
