19adcfe770 Optimise i387 trigonometric functions. Replace "andw 0x400,%ax \ jnz" with
"sahf \ jp", "fprem1" with "fprem" and "fstsw %ax" with "fnstsw %ax".

410484186a Use __FBSDID() instead of RCSID() in most .S files under lib/msun/i386,
and one under lib/msun/amd64.  This avoids adding the identifiers to the
.text section, and moves them to the .comment section instead.

4af1dcdee0 Use, in uncovered part, the END() macro in order to improve debugging.
In this specific case, Valgrind won't get confused when analyzing such
functions.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

2a8fd4fc31 J.T. Conklin's latest version of the Sun math library.
-- Begin comments from J.T. Conklin:
The most significant improvement is the addition of "float" versions
of the math functions that take float arguments, return floats, and do
all operations in floating point.  This doesn't help (performance)
much on the i386, but they are still nice to have.

The float versions were orginally done by Cygnus' Ian Taylor when
fdlibm was integrated into the libm we support for embedded systems.
I gave Ian a copy of my libm as a starting point since I had already
fixed a lot of bugs & problems in Sun's original code.  After he was
done, I cleaned it up a bit and integrated the changes back into my
libm.
