|
* We use the technique used in the OSF Mach kernel code: |

* generate asm statements containing #defines, |
|
* compile this file to assembler, and then extract the |
|
* #defines from the assembly-language output. |

* On sparc, thread_info data is static and TI_XXX offsets are computed by hand. |
