jtc c6edc05829 Assembly language version of the swab function.
This version is only slightly faster than the code generated by gcc on
my i486, but it is almost twice as small.  My i386 timing chart indicates
that this should be significantly faster than the gcc code on a i386.

Surprisingly, none of the code in the source tree actually use this routine.
But I optimized this routine for some image processing programs I wrote, and
I see no reason why everyone else shouldn't share the (admittedly) modest
benifits.

brezak 1ee5779f11 Clear direction flag. Too many folks were losing... 1993-09-19 19:16:27 +00:00
jtc 4dde406083 Shave a cycle or two. Fix comment. 1993-09-07 16:50:29 +00:00

mycroft ed55107bda Add `.text' before the .asciz strings for RCS identifiers. 1993-08-26 02:11:52 +00:00
jtc 35aa0934e7 Note that code originated in locore.s.
Don't bother clearing %eax in bcopy(), it doesn't return anything so
why clear a return value that never gets used?
Don't bother clearing direction flag.  Any code that doesn't set/clear
it explicitly before a string instruction deserves to loose.
