摘要： A TRANSACTION BEGIN instruction begins execution of a transaction and includes a general register save mask having bits, that when set, indicate registers to be saved in the event the transaction is aborted. At the beginning of the transaction, contents of the registers are saved in memory not accessible to the program, and if the transaction is aborted, the saved contents are copied to the registers.

摘要： Machine instructions, referred to herein as a long Convert from Zoned instruction (CDZT) and extended Convert from Zoned instruction (CXZT), are provided that read EBCDIC or ASCII data from memory, convert it to the appropriate decimal floating point format, and write it to a target floating point register or floating point register pair. Further, machine instructions, referred to herein as a long Convert to Zoned instruction (CZDT) and extended Convert to Zoned instruction (CZXT), are provided that convert a decimal floating point (DFP) operand in a source floating point register or floating point register pair to EBCDIC or ASCII data and store it to a target memory location.

摘要： Copying characters of a set of terminated character data from one memory location to another memory location using parallel processing and without causing unwarranted exceptions. The character data to be copied is loaded within one or more vector registers. In particular, in one embodiment, an instruction (e.g., a Vector Load to block Boundary instruction) is used that loads data in parallel in a vector register to a specified boundary, and provides a way to determine the number of characters loaded. To determine the number of characters loaded (a count), another instruction (e.g., a Load Count to Block Boundary instruction) is used. Further, an instruction (e.g., a Vector Find Element Not Equal instruction) is used to find the index of the first delimiter character, i.e., the first termination character, such as a zero or null character within the character data. This instruction checks a plurality of bytes of data in parallel.

摘要： Embodiments relate to intra-instructional transaction abort handling. An aspect includes using an emulation routine to execute an instruction within a transaction. The instruction includes at least one unit of operation. The transaction effectively delays committing stores to memory until the transaction has completed successfully. After receiving an abort indication, emulation of the instruction is terminated prior to completing the execution of the instruction. The instruction is terminated after the emulation routine completes any previously initiated unit of operation of the instruction.

摘要： Multiple sets of character data having termination characters are compared using parallel processing and without causing unwarranted exceptions. Each set of character data to be compared is loaded within one or more vector registers. In particular, in one embodiment, for each set of character data to be compared, an instruction is used that loads data in a vector register to a specified boundary, and provides a way to determine the number of characters loaded. Further, an instruction is used to find the index of the first delimiter character, i.e., the first zero or null character, or the index of unequal characters. Using these instructions, a location of the end of one of the sets of data or a location of an unequal character is efficiently provided.

摘要： A TRANSACTION BEGIN instruction and a TRANSACTION END instruction are provided. The TRANSACTION BEGIN instruction causes either a constrained or nonconstrained transaction to be initiated, depending on a field of the instruction. A constrained transaction has one or more restrictions associated therewith, while a nonconstrained transaction is not limited in the manner of a constrained transaction. The TRANSACTION END instruction ends the transaction started by the TRANSACTION BEGIN instruction.

摘要： When an abort of a transaction occurs, a determination is made as to whether diagnostic information is to be stored in one or more transaction diagnostic blocks (TDBs). There are different types of transaction diagnostic blocks to accept diagnostic information depending on the type of abort and other considerations. As examples, there are a program-specified TDB in which information is stored if a valid TDB address is provided in a transaction begin instruction; a program interruption TDB, which is stored into when the program is aborted due to an interruption; and a program interception TDB, which is stored into when an abort results in an interception.

摘要： An operation is provided to signal a processor that action is to be taken to facilitate execution of a transaction that has aborted one or more times. The operation is specified within an instruction or is itself an instruction. The instruction is executed based on detecting an abort of the transactions, and includes a field indicating how many times the transaction has aborted. The processor uses this information to determine what action is to be taken.

摘要： A TRANSACTION ABORT instruction is used to abort a transaction that is executing in a computing environment. The TRANSACTION ABORT instruction includes at least one field used to specify a user-defined abort code that indicates the specific reason for aborting the transaction. Based on executing the TRANSACTION ABORT instruction, a condition code is provided that indicates whether re-execution of the transaction is recommended.
