The article explores the behavior of shifting registers by more than their size in different processor architectures. It compares the behavior of various architectures, including historic ones like 8086 and 68000, and current ones like x86-32. The author notes that the wide variety of behavior when shifting by more than the register size is one of the reasons why the C and C++ languages leave undefined what happens in such cases. The article also includes some bonus chatter about the 80286 and 80186 processors, their shift count behavior, and their release dates. Overall, this article provides developers with insights into the behavior of shifting registers in different processor architectures, which can be useful for understanding the nuances of low-level programming.
