Function core::arch::x86_64::_mm_cvtss_si64

pub unsafe fn _mm_cvtss_si64(a: __m128) -> i64

This is supported on x86-64 and target feature sse only.

Convert the lowest 32 bit float in the input vector to a 64 bit integer.

The result is rounded according to the current rounding mode. If the result cannot be represented as a 64 bit integer the result will be 0x8000_0000_0000_0000 (std::i64::MIN) or trigger an invalid operation floating point exception if unmasked (see _mm_setcsr).

This corresponds to the CVTSS2SI instruction (with 64 bit output).
