The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows better performance to the generic lgammaf. The code was adapted to glibc style, to use the definition of math_config.h, to remove errno handling, to use math_narrow_eval on overflow usage, and to adapt to make it reentrant.
