| * @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. |
