isaki | Rewrite around BFFFO inline asm.
o Prepare C version of BFFFO (from XM6i).
It is helpful in running FPE on other platforms (for example, for a
test). It is also helpful in porting to non-m68k 3rd party :)
o A BFFFO is supported on 68020 or later (though I'm not sure whether
sun2/68010 uses this FPE correctly or not).

PR 7220 from Ken Nakata:
I've fixed most (not all) m68k FPE bugs that give bogus
calculation results, esp. fsqrt instruction. Also, the internal FP
representation has been reduced from 115-bit mantissa to 67-bit
mantissa which reduced the required mantissa operation roughly by one
fourth. I've done an extensive (though not exhaustive - it's
impossible!) test on the internal routines by feeding them randomly
generated FP numbers, and found that the new code is more precise than
MC68040 FPU (it seems to have a rounding bug).
[ Only change was to keep fpu_calcea.c's name instead of renaming to
fpu_ea.c in Ken's patch. --akb ]

briggs | branches: 1.2.24; 1.2.26; 1.2.28;
Update for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized.

briggs | Still incomplete, but much more complete FPE from Ken Nakata
<kenn@remus.rutgers.edu>. This emulator does not yet emulate
the following functions:
FSINH, FETOXM1, FTANH, FATAN, FASIN, FATANH, FSIN, FTAN,
FETOX, FTWOTOX, FTENTOX, FCOSH, FACOS, FCOS, FSINCOS
It is sufficient, however, to allow programs like df, w, and newfs,
to run to completion with correct results.
Portions of this code were based on the sparc fpe and on initial
work by gwr.

itojun | bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch
just for reference purposes.
This commit includes 1.4 -> 1.4.1 sync for kame branch.
The branch does not compile at all (due to the lack of ALTQ and some other
source code). Please do not try to modify the branch, this is just for
referenre purposes.
synchronization to latest KAME will take place on HEAD branch soon.

he | Apply patch (requested by is):
Revert floating point emulation software to the version released
as NetBSD 1.4. The upgrade done in 1.4.1 had problems.
