| 1.15 |
| 26-Mar-2013 |
isaki | u_int -> uint32_t
|
| 1.14 |
| 22-Mar-2013 |
isaki | Fix fpu_ftox().
Update not only exponential but also mantissa when an integer part
becomes 2 by rounding up. Without this fix, the extended precision
value becomes 0.0 because mantissa (including explicit integer bit)
is all-zero.
|
| 1.13 |
| 19-Mar-2013 |
isaki | Remove 'register'.
|
| 1.12 |
| 18-Jul-2011 |
isaki | branches: 1.12.2; 1.12.12;
fix indent. no functional changes.
|
| 1.11 |
| 14-Mar-2009 |
dsl | Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
|
| 1.10 |
| 14-Mar-2009 |
dsl | Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

agc | Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22364, verified by myself.

rename round() to fpu_round() to avoid a name conflict with
the "round" assembly function in FPSP when building with ELF.

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 ]

| 1.3 |
| 19-Jul-1997 |
is | branches: 1.3.14; 1.3.16; 1.3.18;
Fix my own PR port-m68k/3871, nee port-amiga/3871:
- don't erase FPSR exception bits _after_ doing most of the operations in
fpu_implode(), erase them before doing arith and store operations. This fixes
losing the DZ bit.
- create FPSR_OVFL and FPSR_UNFL bits in fpu_implode(). This showed up when
the first error was fixed.
XXX some more work needs to be done. E.g., creating OPERR together with
OVFL looks bogus, but I'm too tired know to re-check docs; and at least we
pass our own regression tests know.

| 1.2 |
| 30-Apr-1996 |
briggs | Update for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized.
|
| 1.1 |
| 03-Nov-1995 |
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.

| 1.3.18.1 |
| 30-Nov-1999 |
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.
