Adhemerval Zanella	ae679a0aca	math: Use asinpif from CORE-MATH ... The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows better performance to the generic asinpif. The code was adapted to glibc style and to use the definition of math_config.h (to handle errno, overflow, and underflow).
