Function tracing_core::stdlib::arch::x86_64::_bextri_u64

pub unsafe fn _bextri_u64<const CONTROL: u64>(a: u64) -> u64

Available on x86-64 only.

Extracts bits of a specified by control into the least significant bits of the result.

Bits [7,0] of control specify the index to the first bit in the range to be extracted, and bits [15,8] specify the length of the range. For any bit position in the specified range that lie beyond the MSB of the source operand, zeroes will be written. If the range is empty, the result is zero.
