Abstract: A Vector Galois Field Multiply Sum and Accumulate instruction. Each element of a second operand of the instruction is multiplied in a Galois field with the corresponding element of the third operand to provide one or more products. The one or more products are exclusively ORed with each other and exclusively ORed with a corresponding element of a fourth operand of the instruction. The results are placed in a selected operand.

Abstract: A Vector Checksum instruction. Elements from a second operand are added together one-by-one to obtain a first result. The adding includes performing one or more end around carry add operations. The first result is placed in an element of a first operand of the instruction. After each addition of an element, a carry out of a chosen position of the sum, if any, is added to a selected position in an element of the first operand.
Abstract translation: 矢量校验和指令。 来自第二个操作数的元素逐个加入，以获得第一个结果。 添加包括执行一个或多个结束周围的附加操作。 第一个结果被放置在指令的第一个操作数的元素中。 在每个添加元素之后，如果有的话，将和的选择位置的进位添加到第一操作数的元素中的选定位置。

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 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.

Abstract: Vector exception handling is facilitated. A vector instruction is executed that operates on one or more elements of a vector register. When an exception is encountered during execution of the instruction, a vector exception code is provided that indicates a position within the vector register that caused the exception. The vector exception code also includes a reason for the exception.

Abstract: Processing of character data is facilitated. A Find Element Equal instruction is provided that compares data of multiple vectors for equality and provides an indication of equality, if equality exists. An index associated with the equal element is stored in a target vector register. Further, the same instruction, the Find Element Equal instruction, also searches a selected vector for null elements, also referred to as zero elements. A result of the instruction is dependent on whether the null search is provided, or just the compare.

Abstract: Embodiments of the invention relate to implementing run-time instrumentation indirect sampling by instruction operation code. An aspect of the invention includes reading sample-point instruction operation codes from a sample-point instruction array, and comparing, by a processor, the sample-point instruction operation codes to an operation code of an instruction from an instruction stream executing on the processor. A sample point is recognized upon execution of the instruction with the operation code matching one of the sample-point instruction operation codes. The run-time instrumentation information is obtained from the sample point. The run-time instrumentation information is stored in a run-time instrumentation program buffer as a reporting group.

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.
