Extracts the lowest set bit from the source operand and set the corresponding bit in the destination. The corresponding Intel® AVX2 instruction is BLSI.
extern unsigned int _blsi_u32(unsigned int source); |
extern unsigned __int64 _blsi_u64(unsigned __int64 source); |
source |
the source from where the bits are extracted |
Extracts the lowest set bit from the source operand and sets the corresponding bit in the destination. All other bits in the destination are set to 0. If no bits are set in the source operand, all the bits in the destination are set to 0.
Result of the operation.
