This week’s puzzle is to copyÂ the carry flag to the high bit of ah.Â You may destroy any other register,Â the flags, and the other 24 bits of eax.Â Shortest sequence wins.
I just found out the hard way that in 32 bit programs under Win64, the value of CS changed. In Win32, the value of CS is 0x001B. In 32 bit programs under Win64, it’s 0x0023. This will probably break some programs, especially debuggers.
