396 | ### If you add support for a new configuration, add code to this | |
397 | ### switch statement to recognize your configuration name and select | |
398 | ### the appropriate operating system and machine description files. | |
399 | ||
400 | ### You would hope that you could choose an m/*.h file pretty much | |
401 | ### based on the machine portion of the configuration name, and an s/*.h | |
402 | ### file based on the operating system portion. However, it turns out | |
403 | ### that each m/*.h file is pretty manufacturer-specific - for | |
404 | ### example mips.h is MIPS | |
405 | ### So we basically have to have a special case for each | |
406 | ### configuration name. | |
407 | ### | |
408 | ### As far as handling version numbers on operating systems is | |
409 | ### concerned, make sure things will fail in a fixable way. If | |
410 | ### /etc/MACHINES doesn't say anything about version numbers, be | |
411 | ### prepared to handle anything reasonably. If version numbers | |
412 | ### matter, be sure /etc/MACHINES says something about it. | |
