| 435 | jermar | 40 | * This macro roughly follows steps from 1 to 19 described in |
| 41 | * Intel Itanium Architecture Software Developer's Manual, Chapter 3.4.2. |
||
| 42 | * |
||
| 438 | jermar | 43 | * HEAVYWEIGHT_HANDLER macro must cram into 16 bundles (48 instructions). |
| 44 | * This goal is achieved by using procedure calls after RSE becomes operational. |
||
| 45 | * |
||
| 435 | jermar | 46 | * Some steps are skipped (enabling and disabling interrupts). |
| 47 | * Some steps are not fully supported yet (e.g. interruptions |
||
| 438 | jermar | 48 | * from userspace and floating-point context). |
