MIPS: math-emu: Reinstate sNaN quieting handlers

2015-04-07T23:09:31+00:00

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: LLVMLinux: Silence variable self-assignment warnings.

2015-04-01T15:21:47+00:00

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.

MIPS: math-emu: Switch to using the MIPS rounding modes.

2014-05-23T13:12:38+00:00

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

MIPS: math-emu: Cleanup coding style.

2014-05-23T13:11:15+00:00

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.

MIPS: math-emu: Get rid of the useless parts of exception handling.

2014-05-23T13:11:14+00:00

All it really did was throw a printk for no obvious reason. Signed-off-by: Ralf Baechle

MIPS: math-emu: Replace DP_MBITS with DP_FBITS and SP_MBITS with SP_FBITS.

2014-05-23T13:11:13+00:00

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

MIPS: Whitespace cleanup.

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle
