Abstract: A Load Count to Block Boundary instruction is provided that provides a distance from a specified memory address to a specified memory boundary. The memory boundary is a boundary that is not to be crossed in loading data. The boundary may be specified a number of ways, including, but not limited to, a variable value in the instruction text, a fixed instruction text value encoded in the opcode, or a register based boundary; or it may be dynamically determined.

Abstract: Processing of character data is facilitated. A Vector String Range Compare instruction is provided that compares each element of a vector with a range of values based on a set of controls to determine if there is a match. An index associated with the matched element or a mask representing the matched element is stored in a target vector register. Further, the same instruction, the Vector String Range Compare instruction, also searches a selected vector for null elements, also referred to as zero elements.

Abstract: A Load to Block Boundary instruction is provided that loads a variable number of bytes of data into a register while ensuring that a specified memory boundary is not crossed. The boundary is dynamically determined based on a specified type of boundary and one or more characteristics of the processor executing the instruction, such as cache line size or page size used by the processor.
