+vectorized variants RCPPS and RSQRTPS) with an additional Newton-Rhapson step
 to increase precision instead of DIVSS and SQRTSS (and their vectorized
 variants) for single precision floating point arguments.  These instructions
 are generated only when @option{-funsafe-math-optimizations} is enabled
 together with @option{-finite-math-only} and @option{-fno-trapping-math}.
 Note that while the throughput of the sequence is higher than the throughput
 of the non-reciprocal instruction, the precision of the sequence can be
-decreased up to 2 ulp (i.e. the inverse of 1.0 equals 0.99999994).
