_mm512_maskz_cvt_roundpd_epi64 in core::arch::x86_64 - Rust
Description: Convert packed double-precision (64-bit) floating-point elements in a to packed signed 64-bit integers, and store the results in dst using zeromask k (elements are zeroed out if the corresponding bit is not set). Rounding is done according to the ROUNDING parameter, which can be one of:

Convert packed double-precision (64-bit) floating-point elements in a to packed signed 64-bit integers, and store the results in dst using zeromask k (elements are zeroed out if the corresponding bit is not set). Rounding is done according to the ROUNDING parameter, which can be one of:

- `_MM_FROUND_TO_NEAREST_INT` | `_MM_FROUND_NO_EXC` : round to nearest and suppress exceptions
- `_MM_FROUND_TO_NEG_INF` | `_MM_FROUND_NO_EXC` : round down and suppress exceptions
- `_MM_FROUND_TO_POS_INF` | `_MM_FROUND_NO_EXC` : round up and suppress exceptions
- `_MM_FROUND_TO_ZERO` | `_MM_FROUND_NO_EXC` : truncate and suppress exceptions
- `_MM_FROUND_CUR_DIRECTION` : use `MXCSR.RC` - see `_MM_SET_ROUNDING_MODE`
