From: Christophe Lyon <christophe.l...@st.com> 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.
