Gcc helper functions should still use the ENTRY() macro so they will be
...
show up in profiled code. (The gcc helper functions in the other ports
do this allready).

Use PIC_PLT macro with the function calls (as was done with setjmp()).

So many files in arch/i386 have been changed I might as well run my
...
remove unecessary trailing whitespace script.

Change instances of LIBC_RCS back to LIBC_SCCS. If we are going to change
...
th LIBC_RCS, the entire source tree should be updated at once.
Remove && !defined(lint) from conditionals around rcs id's. No one is
ever going to pass a *.s file through lint.

Replaced instructions with immediate operands with compatible alternatives
...
saving a few bytes while the cycle count remains the same --- could
actually be faster, depending on the cache, prefetch queue, etc.

First cut; not sure if it's right. Very like it is, because it's
...
the same as the m68k versions..

Provide i386 versions of div and ldiv -- they are simpler than the C versions,
...
since the idiv instruction does the right thing wrt truncating towards zero.

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.

Provide an assembly language version of labs().
...
Since ints and longs are both 32 bits on a i386, we could alias abs()
and labs() together as mycroft did with memmove()/memcpy(), but I'm
waiting on an interpretation ruling to see if it is legal.
