Most assembly functions are leaves, so saving/restoring around calls to lower-level functions will be infrequent. I suspect it would be more useful to emit debug records that show how the registers are being used, so that gdb can display meaningful names along with their values. And yes, this requires reading and understanding the comments if the code is well commented, or analyzing the code if it is not well commented. It can't be automated. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
