◆ _mm_clzero()

static __inline__ void __DEFAULT_FN_ATTRS _mm_clzero ( void *  __line)

Zeroes out the cache line for the address __line.

This uses a non-temporal store. Calling _mm_sfence() afterward might be needed to enforce ordering.

This intrinsic corresponds to the CLZERO instruction.

__lineAn address within the cache line to zero out.
