The code in _sp_maddf (formerly ieee754sp_madd) appears to have been
copied verbatim from ieee754sp_add, and although it's adding the
unpacked "r" & "z" floats it kept using macros that operate on "x" &
"y". This led to the addition being carried out incorrectly on some
mismash of the product, accumulator & multiplicand fields. Typically
this would lead to the assertions "ze == re" & "ze

Revert the changes made by commit fdffbafb [Lots of FPU bug fixes from
Kjeld Borch Egevang.] to `ieee754sp_nanxcpt' and `ieee754dp_nanxcpt'
sNaN quieting handlers and their callers so that sNaN processing is done
within the handlers againg. Pass the sNaN causing an IEEE 754 invalid
operation exception down to the relevant handler. Pass the sNaN in `fs'
where two sNaNs are supplied to a binary operation.Set the Invalid Operation FCSR exception bits in the quieting handlers
rather than at their call sites throughout. Make the handlers exclusive
for sNaN processing.Signed-off-by: Maciej W. Rozycki

Remove variable self-assignments.
This silences a bunch of -Wself-assign warnings reported by clang.
The changed code can be compiled without warnings by both gcc and clang.Signed-off-by: Toma Tabacu

Previously math-emu was using the IEEE-754 constants internally. These
were differing by having the constants for rounding to +/- infinity
switched, so a conversion was necessary. This would be entirely
avoidable if the MIPS constants were used throughout, so get rid of
the bloat.Signed-off-by: Ralf Baechle

o Only define variables in the outermost block
o One empty line at most
o Format comments as per CodingStyle
o Update FSF address in licensing term comment
o Spell FPU and MIPS in all capitals.
o Remove ####-type of lines in comments.
o Try to make things a bit most consistent between sp_*.c / dp_*.c files.Signed-off-by: Ralf Baechle

All it really did was throw a printk for no obvious reason.

Both were defined as 23 rsp. 52 though the mentissa is actually a bit more
than the fraction.Signed-off-by: Ralf Baechle

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
