To: J3 J3/22-149r4 From: Steve Lionel Subject: Taking note of additional processor dependencies Date: 2022-July-19 Reference: 22-007r1 Annex A lists processor dependencies, but it is missing some. The following excerpts appear to describe processor dependencies not currently listed in Annex A. Edits are proposed to add them. - 6.2.5 However, a processor may have a limit on the total number of unique statement labels in one program unit. (This might be considered a complexity limit, see 4.2p7. There are existing entries in Annex A that are also complexity limits.) - 11.1.7.5 If a variable has REDUCE locality, on termination of the DO CONCURRENT construct the outside variable is updated by combining it with the values the construct entity had at completion of each iteration, using the reduce-operation. The processor may combine the values in any order. - 13.8.5 When the leading zero mode is PROCESSOR_DEFINED, the processor has the option of producing a leading zero or not in such positions, subject to 13.7.2(5). - 16.9.59 If there are no command arguments available or if the processor does not support command arguments, then the result has the value zero. (16.9.93) - 16.9.83 If the processor supports command line execution, it shall support synchronous and may support asynchronous execution of the command line. - 16.9.92 If the command cannot be determined, COMMAND is assigned all blanks. Edits ----- Insert into Annex A (550:A.2p1, Processor Dependencies) the following bullet items in subclause order: - the maximum number of unique statement labels in a program unit (6.2.5) - the order in which values are combined in a DO CONCURRENT reduction (11.1.7.5) - whether a leading zero is produced when the leading zero mode is PROCESSOR_DEFINED (13.8.5) - whether command arguments are available (16.9.59, 16.9.93) - whether asynchronous command line execution is available (16.9.83) - whether the program invocation command is available (16.9.92) --END--
