[Qemu-devel] [PATCH v2 0/2] ARM: fix Neon vrecpe instruction.

[christophe.lyon]

From: Christophe Lyon <address@hidden>

These 2 patches fix the ARM Neon vrecpe instruction by matching the
algorithm descibed in the ARM ARM.

With these patches, qemu passes my ARM/Neon tests.

Patch #1 modifies softfloat by exporting float32_nan and
float32_infinity. For consistency, I have also moved all the
target-dependent definitions of floatXX_default_nan to softfloat.h (ie
the 16, 64, x80 and 128 bits versions in addition to the 32 bits
ones).

Patch #2 uses these newly exported values and uses the vrecpe
algorithm described in the ARM ARM.

Christophe Lyon (2):
  softfloat: export float32_nan and float32_infinity.
  target-arm: fix support for vrecpe.
