* | x86_64: Add expm1 with FMA | H.J. Lu | 2023-08-14 | 1 | -0/+10 |
On Skylake, it improves expm1 bench performance by: Before After Improvement max 70.204 68.054 3% min 20.709 16.2 22% mean 22.1221 16.7367 24% NB: Add extern long double __expm1l (long double); extern long double __expm1f128 (long double); for __typeof (__expm1l) and __typeof (__expm1f128) when __expm1 is defined since __expm1 may be expanded in their declarations which causes the build failure. |
