MIPS: math-emu: Reinstate sNaN quieting handlers

2015-04-07T23:09:31Z

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.

MIPS: math-emu: Don't pass qNaNs through quieting handlers

2015-04-07T23:09:29Z

Don't call the `ieee754sp_nanxcpt' and `ieee754dp_nanxcpt' sNaN quieting handlers for a qNaN supplied to floating-point format conversions or SQRT.S/SQRT.D instructions, or for a qNaN produced out of a negative operand supplied to SQRT.S/SQRT.D instructions. Return the qNaN right away in these cases. Signed-off-by: Maciej W. Rozycki Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/9687/ Signed-off-by: Ralf Baechle

MIPS: math-emu: Cleanup coding style.

2014-05-23T13:11:15Z

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.

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