* arch/alpha/lib/ev6-strncpy_from_user.S
* 21264 version contributed by Rick Gorton <rick.gorton@alpha-processor.com>
*
* Just like strncpy except in the return value:
*
* -EFAULT if an exception occurs before the terminator is copied.
* N if the buffer filled.
*
* Otherwise the length of the string is returned.
*
* Much of the information about 21264 scheduling/coding comes from:
* Compiler Writer's Guide for the Alpha 21264
* abbreviated as 'CWG' in other comments here
* ftp.digital.com/pub/Digital/info/semiconductor/literature/dsc-library.html
* Scheduling notation:
* E - either cluster
* U - upper subcluster; U0 - subcluster U0; U1 - subcluster U1
* L - lower subcluster; L0 - subcluster L0; L1 - subcluster L1
* A bunch of instructions got moved and temp registers were changed
* to aid in scheduling. Control flow was also re-arranged to eliminate
* branches, and to provide longer code sequences to enable better scheduling.
* A total rewrite (using byte load/stores for start & tail sequences)
* is desirable, but very difficult to do without a from-scratch rewrite.
* Save that for the future.
