* this file must be compiled without red-

* zone protection, thus all of these

|
* functions are in their own file to

|
* accomodate this.
|

|
*
|

* Calling a function like so:

|
* __attribute__((interrupt)) isr1(registers_t* frame) {}
|
||||||
|
*
|
||||||
|
* allows the function to be used to serve
|
||||||
|
* interrupts - GCC compiles it under unique
|
||||||
|
* conditions, as it preserves the state of
|
||||||
|
* the processor and stack between execution,
|
||||||
|
* as well as using the IRET instruction to
|
||||||
|
* return to the middle of the previous function.
|
||||||
|
*
|
||||||
|
* There is also a version of the interrupt
|
||||||
|
* attribute which allows for error handlers,
|

|
* these having a size_t input as an error code.
