* @brief Stack frame created by swap (IA-32)
|
|
*
|
|
* This file details the stack frame generated by _Swap() when it saves a task
|
|
* or fiber's context. This is specific to the IA-32 processor architecture.
|
|
*
|
|
* NOTE: _Swap() does not use this file as it uses the push instruction to
|
|
* save a context. Changes to the file will not automatically be picked up by
|
|
* _Swap(). Conversely, changes to _Swap() should be mirrored here if the
|
|
* stack frame is modified.
