[Qemu-arm] [PATCH 0/2] target-mips: Fix IEEE 754-2008-related issues

[Aleksandar Markovic]

From: Aleksandar Markovic <address@hidden>

Mips platform represents the most complex case among QEMU-supported
platforms in reference to certain aspects of floating-point arithmetics.
This is mostly a consequence of the fact that Mips platform, for many
reasons, evolved considerably over time related to floating-point
arithmetics standards (significantly more than other platforms).
It has been difficult for emulators like QEMU to support such variety
of configurations.

This patch set provides solution to this problem, and furnishes
accurate emulation of floating-point arithmetics for all Mips cases.

  softfloat: Enable run-time-configurable meaning of signaling NaN bit
  target-mips: Implement IEEE 754-2008 functionality for R6 and MSA
    instructions
