* | optimize exponential asm for i386 | Rich Felker | 2012-03-19 | 1 | -47/+1 |
| | | | | | | up to 30% faster exp2 by avoiding slow frndint and fscale functions. expm1 also takes a much more direct path for small arguments (the expected usage case). | ||||
* | fix broken exponential asm | Rich Felker | 2012-03-18 | 1 | -1/+12 |
| | | | | | | | | | infinities were getting converted into nans. the new code simply tests for infinity and replaces it with a large magnitude value of the same sign. also, the fcomi instruction is apparently not part of the i387 instruction set, so avoid using it. | ||||
