| DESCRIPTION |
| 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. |
