2015-04-08MIPS: math-emu: Remove redundant code from NaN comparisonMaciej W. Rozycki
Remove a redundant call to `ieee754_setandtestcx' in `ieee754sp_cmp' and `ieee754dp_cmp'. The IEEE 754 exception requested will have already been set by a call to `ieee754_setcx' immediately above, because `sig' has to be non-zero to reach here, and the comparison result returned will be 0 regardless of the result from the call. Simplify the return expression remaining. All this reducing the size of code by 16 and 12 instructions or 64 and 48 bytes respectively. Signed-off-by: Maciej W.

2015-04-08MIPS: math-emu: Optimise NaN handling in comparisonsMaciej W. Rozycki
We have the input operands already classified in `ieee754sp_cmp' and `ieee754dp_cmp' comparison operations, so use the class obtained to tell NaNs and numbers apart rather than classifying inputs again for this purpose, reducing the size of code by 24 and 40 instructions or 96 and 160 bytes respectively.

2014-05-23MIPS: math-emu: Cleanup coding style.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.

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!
