Re: z/TPF List Server
There is a moderated newsgroup, comp.os.tpf, which was created in January 1999 (vote in November 1988). However, the last legitimate post occurred in July of 2002, and I believe that the moderator is no longer around. The original RFD was put out by Andre Rosenthal and can be found in this Google Groups USENET archive: http://tinyurl.com/2ndtf7 I don't know the procedure for the Big 8 to change moderation, but that might be a way to go.

Re: CMSCALL return code
There is a new option now, especially with non-zero codes: LHI R15,4 No storage fetch. The subject of instruction timings on IBM-MAIN and ASSEMBLER-LIST comes up now and then. I point y'all to the archives of both lists. With the new z/Architecture pipelines and caches, sometimes what seems at first to be illogical instruction placement may actually be better. Hypothetical illustration example: LR4,RECPTRLoad address of pointer AHI R6,1 Add 1 to counter AHI R8,(-8) Some other strange counter CLI 16(R4),X'40' JE GOHERE The z/Architecture processor will execute the two AHI instructions while the base/displacement calculation and storage access for the L instruction is occurring, because it knows that R4 isn't affected by those instructions. By the time the CLI is hit R4 will contain the address and there is no delay that might occur if you code AHI R6,1 Add 1 to counter AHI R8,(-8) Some other strange counter LR4,RECPTRLoad address of pointer CLI 16(R4),X'40' JE GOHERE In this case, there might be a delay at the CLI. Speaking of branches there's been an interesting discussion recently about the branch-prediction logic in z/Architecture, which is why I demonstrate with the RI (or is it IR? I can never remember) instruction.

Slightly off-topic: if I remember correctly, we argued intensely about zeroing a GPR and the performance differences between: - SR R15,R15 - XR R15,R15 - LA R15,0(not seriously considered by performance geeks) - L R15,=F'0' (considered for use only by amateur programmers coming from a BASIC or COBOL background and otherwise held in low esteem by real programmers). ;-) IIRC, the actual performance difference between SR and XR was different based more on specific processor models that anything else.

However, the discussion had more to do with fetches of boundary-aligned vs. non-aligned data. There was no mention of the optimum speed for getting either a specific or an arbitrary value loaded into a register. In this day of pipelined machines This is sort of reminiscent of the good old days, programming in 7080 Autocoder. Boeing insisted that the programmers use a MOVE macro because there were 26 different ways to move data from one storage location to another. It was expected that most programmers would use either their favorite way or the first one that popped into their heads if left on their own. The macro chose the optimal way, depending on the operand definitions.

Schuh, Richard wrote: I really would not have left it to chance, I would have defined a word-aligned constant rather than using a literal. However, it might not have been as chancy as it may seem. The literal pool is doubleword aligned and boundary alignment may have been a factor in determining where the literal resided. I would like to think that the 8-byte multiples are put at the front, the 4-byters next, then the twos followed by everybody else. In looking at an assembly listing, that seems to be the sequence. The first two literals in the program are =x'A00', the next =x'FF', etc. In the literal pool, all 4 byte entries (there were no 8 byte literals) precede the two byte literals and then come the ones of only 1 byte. Within each of these groups, the literals appear in the order in which they were defined. There were no long strings defined as literals in the particular listing. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Don Russell Sent: Tuesday, November 21, 2006 3:46 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: CMSCALL return code Schuh, Richard wrote: I agree, it does seem non-intuitive.

Two is a number. :-) Not IBM-specific, but S/390 architecture specific: the smaller Fujitsu-Siemens SX series are really non-Intel Sun boxes running an emulator, with BS2000/OSD and VM2000 running on top. (The S-series are real boxes.) I think that F-S may also have some Intel boxes doing this as well. Unisys is moving towards the same scenario with its 2 mainframe lines, both called ClearPath, but differentiated by origins (Sperry or Burroughs) and operating systems (OS2200, MCP).
