[PATCH 0/6] MIPS: math-emu: FP emulation fixes and improvements

[Aleksandar Markovic]

From: Aleksandar Markovic <aleksandar.markovic@xxxxxxxxxx>

This series includes:

  - a fix for certain SIGILL program crashes on issuing a valid
    CMP instruction
  - a fix for RINT emulation inaccuracies
  - a fix for the output of CLASS.D instruction emulation
  - several FP emulation debugfs statistics improvements

The patches in this series are logically and physically
independent on the patches previously sent in "Misc" series.
This means that these two series can be applied independently,
in any order.

The script "checkpatch --strict" returns a check and a warning
iff aplied on the patch 6. However, they are unavoidable if the
code is to be kept consistent in the file me-debugfs.c.

Aleksandar Markovic (6):
  MIPS: math-emu: CMP.Sxxx.<D|S>: Prevent occurences of SIGILL crashes
  MIPS: math-emu: RINT.<D|S>: Fix several problems by reimplementation
  MIPS: math-emu: CLASS.D: Zero bits 32-63 of the result
  MIPS: math-emu: Add FP emu debugfs statistics for branches
  MIPS: math-emu: Add FP emu debugfs reset functionality
  MIPS: math-emu: Add FP emu debugfs stats for individual instructions
