When debugging x86 assembly code in VS2013, I needed to check the contents of the FLAGS register. However, when I've enabled "Flags" in Register Window, I got:
OV = 0 UP = 0 EI = 1 PL = 1 ZR = 0 AC = 1 PE = 0 CY = 1
Those don't correspond to typical ODITSZAPC flags of x86; can anyone explain to me what's going on? Are those just weird names for the same flags?
I have a 64-bit Core i7; can it affect the displayed names?
Yes of course they are the same flags, what else?
But those really are misleading. When UP=1 it's actually reverse back direction (STD), also when PL=1 it's actually sign/negative. Why did VS designer tried to break ASM-thing that ain't broken for ages was beyond my comprehension though.
The same way in GNU's gdb, they called instruction pointer (IP) as $pc, DWORD/DD as word (w), WORD/DW as half-word (h), and QUADWORD/DQ as (g) from GIANT??
C++ Programmers are really weird, they liked to break convention for the sake of it.
