| 32 | /* I did not find any specification (neither MIPS nor PowerPC), but |
- | |
| 33 | * as I found it |
- | |
| 34 | * - it uses Variant II |
- | |
| 35 | * - TCB is at Address(First TLS Block)+0x7000. |
- | |
| 36 | * - DTV is at Address(First TLS Block)+0x8000 |
- | |
| 37 | * - What would happen if the TLS data was larger then 0x7000? |
- | |
| 38 | * - The linker never accesses DTV directly, has the second definition any |
- | |
| 39 | * sense? |
- | |
| 40 | * We will make it this way: |
- | |
| 41 | * - TCB is at TP-0x7000-sizeof(tcb) |
- | |
| 42 | * - No assumption about DTV etc., but it will not have a fixed address |
