Zeroes all YMM registers. The corresponding Intel® AVX instruction is VZEROALL.
extern void _mm256_zeroall(void); |
None
Zeroes all YMM registers. This intrinsic is useful to clear all the YMM registers when transitioning between Intel® Advanced Vector Extensions (Intel® AVX) instructions and legacy Intel® Supplemental SIMD Extensions (Intel® SSE) instructions.
There is no transition penalty if an application clears the bits of all YMM registers (sets to ‘0’) via VZEROALL, the corresponding instruction for this intrinsic, before transitioning between Intel® Advanced Vector Extensions (Intel® AVX) instructions and legacy Intel® Supplemental SIMD Extensions (Intel® SSE) instructions.
