x86_64: Optimize sincos where sin/cos is optimized (bug 29193) The compiler may substitute calls to sin or cos with calls to sincos, thus we should have the same optimized implementations for sincos. The optimized implementations may produce results that differ, that also makes sure that the sincos call aggrees with the sin and cos calls. 2022-05-31 11:09:38 +00:00			`#define __sincos __sincos_fma4`
