| 5 | * We use the technique used in the OSF Mach kernel code: |
| 6 | * generate asm statements containing #defines, |
| 7 | * compile this file to assembler, and then extract the |
| 8 | * #defines from the assembly-language output. |
| 9 | * |
| 10 | * On sparc, thread_info data is static and TI_XXX offsets are computed by hand. |
