## The Interrupt Calling Convention ## The Interrupt Calling Convention
Exceptions are quite similar to function calls: The CPU jumps to the first instruction of the called function and executes it. Afterwards the CPU jumps to the return address and continues the execution of the parent function. Exceptions are quite similar to function calls: The CPU jumps to the first instruction of the called function and executes it. Afterwards the CPU jumps to the return address and continues the execution of the parent function.
However, there is a major difference between exceptions and function calls: A function call is invoked voluntary by a compiler inserted `call` instruction, while an exception might occur at _any_ instruction. In order to understand the consequences of this difference, we need to examine function calls in more detail.

[Calling conventions] specify the details of a function call. For example, they specify where function parameters are placed (e.g. in registers or on the stack) and how results are returned. On x86_64 Linux, the following rules apply for C functions (specified in the [System V ABI]): [Calling conventions] specify the details of a function call.
