2014-05-23MIPS: math-emu: Switch to using the MIPS rounding modes.Ralf Baechle1-7/+0
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>

2014-05-23MIPS: math-emu: Cleanup coding style.Ralf Baechle1-1/+1
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.

LONG_LONG_MAX is a symbol defined in <limits.h> which may not be available so better rely on something provided by a kernel header. While at it, turn these function-like macros into inline functions. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

The struct mips_fpu_soft_struct and mips_fpu_hard_struct are completely same now and the kernel fpu emulator assumes that. This patch unifies them to mips_fpu_struct and get rid of mips_fpu_union. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

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!
