Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change

e09d2f42db
Use "testb %cl,%cl" instead of "cmpb $0,%cl".
...
This saves three cycles per character, and reduces the size of the
function by eight bytes (the loop is unrolled eight times).
Thanks to davidg for pointing this out.
1993-10-08 01:25:51 +00:00
b3f9f8f6f4
Provide an assembly language version of labs().
...
Since ints and longs are both 32 bits on a i386, we could alias abs()

waiting on an interpretation ruling to see if it is legal.
