* MIPS: math-emu: Fix m{add,sub}.s shiftsPaul Burton2016-05-131-2/+4
| | | | | | | | | | | | | | | | | | | 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 <= SP_EMAX" failing since ze & re hadn't been operated upon.

* MIPS: math-emu: Reinstate sNaN quieting handlersMaciej W. Rozycki2015-04-081-4/+5
| | | | | | | | | | | | | | | | | | 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.Toma Tabacu2015-04-011-5/+0
| | | | | | | | | | | | | | 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.Ralf Baechle2014-05-231-2/+2
| | | | | | | | | | 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 <ralf@linux-mips.org>
* MIPS: math-emu: Cleanup coding style.Ralf Baechle2014-05-231-25/+28
| | | | | | | | | | | | 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.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+177
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!
