Abstract: Instructions and logic provide extended vector suffix comparisons for Boyer-Moore searches. Some embodiments, responsive to an instruction specifying: a pattern source operand and a target source operand, compare each of m data elements of the pattern operand with each data element of the target operand. A first and second equal ordered aggregation operation are performed from the comparisons according to the m data elements of the pattern source operand. A result of the first and second aggregation operations indicating whether or not a possible match exists between the m data elements of the pattern source operand and d data element positions relative to data elements of the target source operand is stored. Ordering of the data elements of the pattern and the target operands may be reversed for the second aggregation operation, and d may be a sum of m?1 and the quantity of target operand elements in some embodiments.

Abstract: A processor includes a plurality of packed data registers. The processor also includes a decode unit to decode a packed variable length code point length determination instruction. The instruction is to indicate a first source packed data that is to have a plurality of packed variable length code points that are each to represent a character. The instruction is also to indicate a destination storage location. The processor also has an execution unit coupled with the decode unit and the packed data registers. The execution unit, in response to the instruction, is to store a result packed data in the indicated destination storage location. The result packed data is to have a length for each of the plurality of the packed variable length code points. Other processors, methods, systems, and instructions are also disclosed.
