* Compute (1 - x^2) as ((1 - x) * (1 + x)) instead of as (1 - x * x) toBruce Evans1997-02-202-11/+23
| | | | | | | | | | | | | | | | | | avoid easily avoidable loss of precision when |x| is nearly 1. Extended (64-bit) precision only moves the meaning of "nearly" here. This probably could be done better by splitting up the range into |x| <= 0.5 and |x| > 0.5 like the C version. However, ucbtest does't report any errors in this version. Perhaps the C version should be used anyway. It's only 25% slower now on a P5, provided the C version of sqrt() isn't used, and the C version could be optimized better.

* Select between the generic math functions and the i387-specific onesBruce Evans1997-02-1625-56/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Disabled the i387 version if log1p(). It just evaluates log(1 + x).Bruce Evans1997-02-151-2/+4
| | | | | | | | | | | | 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).

* Made rintf() actually work. It was completely broken (when s_rint.cBruce Evans1996-08-282-6/+19
| | | | | | | | | | | | | | was compiled with -O) by the precision bug in the i386 version of gcc (assignments and casts don't clip the precision). E.g., rintf(12.3456789) was 12.125. Avoid the same bug in rint(). It was only broken for the unusual case when the i387 precision is 64 bits. FreeBSD defaults to 53 bit precision to avoid problems like this, but the standard math emulator always uses 64 bit precision. Notes: svn path=/head/; revision=17860
