2013-08-15 | math: fix x86 asin, atan, exp, log1p to raise underflow | Szabolcs Nagy | 1 | -0/+10 | |
underflow is raised by an inexact subnormal float store, since subnormal operations are slow, check the underflow flag and skip the store if it's already raised | |||||
2012-03-19 | asm for inverse trig functions | Rich Felker | 1 | -0/+7 | |
unlike trig functions, these are easy to do in asm because they do not involve (arbitrary-precision) argument reduction. fpatan automatically takes care of domain issues, and in asin and acos, fsqrt takes care of them for us. |
