/*

|
* This program is used to generate definitions needed by
|
||
|
|
* assembly language modules.
|
||
|
|
*
|
||
|
|
* 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.
