05b706676b Add alpha support. m68k crept in too. Oops. 8-) 1998-02-20 07:44:29 +00:00

3bc097d098 Added -D_ARCH_INDIRECT=i387_ to CFLAGS. _ARCH_INDIRECT will soon be used
to control generation of indirections in ENTRY().  Only msun needs it.

Use ${ARCH} consistently.

2e6184e901 Split up the Bessel function wrapper files so that most wrapper functions
are in their own file.

dab159e3d6 Select between the generic math functions and the i387-specific ones
at runtime.

etc/make.conf:
Nuked HAVE_FPU option.

lib/msun/Makefile:
Always build the i387 objects.  Copy the i387 source files at build
time so that the i387 objects have different names.  This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.

lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.

lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.

sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization.  The PIC case is
messy.  The old i387 entry points are renamed.  Renaming is easier
here because the names are given by macro expansions.

c4ebcb3423 Put back .endif clobbered by the previous commit, breaking the
build.

ec7d3a3282 Disabled the i387 version if log1p(). It just evaluates log(1 + x).
This defeats the point of log1p().  ucbtest reports errors of +-5e+15
ULPs.  A correct version would use the i387 fyl2xp1 instruction for
small x and maybe scale to small x.  The C version does the scaling
reasonably efficiently, and fyl2px1 is slow (at least on P5s), so not
much is lost by always using the C version (only 25% for small x even
with the broken i387 version; 50% for large x).

1130b656e5 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.

e76da59456 Delete -D_POSIX_MODE and -D_MULTI_LIBM from CFLAGS. They never had any effect
because _IEEE_LIBM always takes priority, so the definition just served
to confuse.

c211e812bb Added some missing MLINKS for section 3 man pages.
Also corrected a few minor formatting errors, file location and cross
references in some of the section 3 man pages.

This shuts up a lot of the output from "manck" for section 3.

6644bf3e9b Undo the the changes in the previous revision (MANSRC now works right again).
Use ${INSTALL} instead of install.

973f098aab Compress manual pages (if desired) in the obj directory rather
than in the installation destination.  Should make release-building
substantially faster.  The msun Makefile changes simple adapt to the new
scheme.

3a8617a83f 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.
