Question about compiled programs on a newer machine type be usable ?

by babydr DBA James W. Laferriere

Hello all , Here I am again , Maybe my ? might be relative to the community . I grabbed an archive of precompiled gnu software , During the extraction I got a 'warning' from a gzip'd tar & decided to dig into the underlying tarball to see if it was trully corrupted or repairable . Tada , I did a silly and less'd one of the binary files and noticed that the underlying file was 'ar'd by /usr/local/alphaev6-dec-osf5.1b/bin/ar , well all said and done My ol' as100 ain't a ev6 . So my Question , Could I use these programs that were created on a ev6 cpu system on my ev4 ? Tia , JimL -- +---------------------------------------------------------------------+ | James W.

When/how did ctime change from inode "creation" to "change" time?

by Theodore Ts'o

As part of a discusion on the Linux kernel mailing list, there was an assertion that ctime was orginally "creation time". From the v7 sources in TUHS, we can see: struct dinode { unsigned short di_mode; /* mode and type of file */ short di_nlink; /* number of links to file */ short di_uid; /* owner's user id */ short di_gid; /* owner's group id */ off_t di_size; /* number of bytes in file */ char di_addr[40]; /* disk block addresses */ time_t di_atime; /* time last accessed */ time_t di_mtime; /* time last modified */ time_t di_ctime; /* time created */ }; ... although the v7 kernel sources does seem to update ctime when the inode metadata changes, regardless of what the coment in /usr/src/sys/h/ino.h might say. More interestingly, this comment seems to continue in newer versions up to 3BSD, and then the comments becomes "change time" in BSD 4.2, probably coincident with the File System Implementation? The best we can guess is that the change from "creation time" to "inode change time" happened sometime between 1979 and 1982. Does anyone who was around can give the story about how and when this happened? - Ted

Sad news: we lost George Colouris

by H.J.Thomassen

In July 1974 I visited Bell Labs Murray Hill, and Ken & Dennis showed me around. I was very impressed because we (Univ of Nijmegen, NL) had a PDP-11/45 just like theirs and I knew that machine quite well. It was clear that their software kicked the machine much heavier than our (DEC-original) DOS-system did. But I was a naive student so I wanted more information and asked Ken: are there many UNIX users in Europe? Ken brought us to the library where a Ms. Irma B. Biren, librarian, kept the record of licenses. We found prof. Colouris in London... When I asked whether maybe somebody closer by our place was present, Ken found Gideon Yuval in Tel Aviv. Nobody closer.... Hendrik-Jan Thomassen

Re: What would early alternatives to C have been?

by Douglas McIlroy

Yacc certainly makes it easier to write parsers for big grammars, but it's far from cheating. You need to know a lot more about parsing to use Yacc than you need to roll your own. Hand parsing of a tiny grammar is almost a necessary step on the way to understanding Yacc. But I think hand-building the whole parser for a compiler is unnecessary torture--like doing trigonometry with log tables. Doug

"Webster's Second on the Head of a Pin"?

by Royce Williams

Someone I know is seeking the original version of an internal Bell Labs memo from 1974 titled "Webster's Second on the Head of a Pin" by Morris and Thompson. The topic appears to be related to improving the speed of lookups or search. It's cited in a few papers as "Unpublished Technical Memo, Bell Laboratories, Murray Hill, NJ 1974." All I can find online is citations. Any leads appreciated! -- Royce

What would early alternatives to C have been?

by Dan Cross

As I mentioned in the discussion about C, it's easy to look back with a modern perspective and cast aspersions on C. But this got me thinking, what would possible alternatives have been? In the context of the very late 1960s heading into the early 70s, and given the constraints of the PDP-7 and early PDP-11s, what languages would one consider for implementing a system like early Unix? Dennis's history paper mentioned a very short-lived effort at Fortran, and I asked about that a few years ago, but no one really remembered much about it; I gather this was an experiment that lasted a few days or weeks and was quickly abandoned. But what else? My short list included PL/1, Algol/W, Fortran, and Pascal. Fortran was already mentioned. I don't think PL/1 (or PL/I) could have fit on those machines. Pascal was really targeted towards teaching and would have required pretty extensive work to be usable. The big question mark in my mind is Algol/W; how well known was it at the time? Was any consideration for it made? Obviously, the decision to go with BCPL (as the basis for B, which beget C) was made and the rest is history. But I'm really curious about how, in the research culture at the time, information about new programming languages made its way through the community. - Dan C.

Isn’t APL syntax rather context sensitive[1]? Neither yacc nor a RD parser would’ve helped! Unless the subset was limited to a context free subset. Tim Budd in his 1978 work made quite a few changes to APL to ease compilation and used yacc. [I have the book somewhere....] [1] I do not recall if Iverson's original APL had a context sensitive grammar but modern APLs do. Given an expression ‘x y z’, its parse depends on the types of x, y & z. Example: y(x,z) if y is a dyadic verb, x & z are values, x(y(z)) if x & y are monadic verbs, z a value etc.

DCJ-11 processor with 20k FPGA

by Jason Stevens

I assume people have seen this? https://github.com/ryomuk/TangNanoDCJ11MEM/tree/main It's capable of running Unix v1 & some limited amount of v6 among other things. The FPGA in question the Tang Nano 20k is sub 30GBP delivered from AliExpress. Kind of neat to combine a real processor with a simple FPGA implementation of the hardware.

Re: BWK on possible alternative programming languages

by Douglas McIlroy

Adding to Brian's remarks. Both PL/I, which had been adopted by Multics, and BCPL/B were very familiar. PL/I , even gutted as it had been for Multics, was much too big to contemplate. BCPL's integration of subscripting and pointers was nice, as was its closeness to the machine. Typlessness was a drawback: how would one integrate floating point or characters? Another was the global vector, like Fortran COMMON. Algol W was known (to me, at least) only via its publication in CACM. I don't recall it having been considered. Because Algol W had more concepts than BCPL,was not as closely matched to machine-level coding, and (I believe) was equally lacking in separate-compilation facilities, I suspect it would not have made the cut.

> From: Phil Budne > BUT, the basic TCP and IP protocols seem to have been created with a > general care that two byte fields should be aligned at multiples of two > bytes Yes, because dealing with a 16-bit field that spans two PDP-11 16-bit words is a pain (espcially because the PDP-11 does not have a 'load byte into register _without_ extending the sign bit into the high half' instruction). Do realize that in addition to the early TCP implementation, the _first_ TCP router (at that stage, TCP and IP were not separate protocols) was also a PDP-11 (albeit programmed in BCPL, not MACRO-11). I remember the extension being a real PITA. To load an un-aligned 16-bit quantity into R0, one would have had to do something like (assuming a pointer to the un-aligned 16-bit quantity was in R1): MOVB (R1)+, R0 SWAB R0 BIC #0377, R0 BISB (R1)+, R0 There may have been a better way to do it, but that's the best I can come up with now; I recall we had to do something like that. Yes, the 16-bit fields were 16-bit word aligned. Noel

the code in the repo is for the FPGA, the processor that is strapped to the FPGA well it runs the real code. It's like the 'minimig' Amiga emulator platform, a real processor, and FPGA to do all the IO heavy lifting. So it's not 100% FPGA but you are executing code on a real processor so you aren't exactly full emulation either.

I'm confused; I thought device register layout is inherently about as non-portable a thing as one could have, generally. (Exceptions: 1) the device is basically a single chip, so interfaces on two machines might be essentially identical, if they use the same chip; 2) someone made a 68K card that plugged into a QBUS, so drivers on a PDP-11 and that 68K could be identical.) Or did you mean that one could somehow disassociate the struct layout and the details of the device (assuming it has addressable registers, as became common)? How (I'm missing it)? Noel

Alignment is just one aspect of low-level binary representation; there's also length (in bits), which is critically important in several problem domains; device registers have already been mentioned, but more below. > From: Peter Yardley > Problems I have with C as a systems language is there is no certainty > about representation of a structure in memory and hence when it is > written to disk. That's yet another one. The area I'm thinking of (and which I saw a lot of) is code to implement network protocols (and I'm fairly astounded that nobody else has mentioned this yet). One has to have _absolute_ control over how the bits are laid out in the packet (which of course might wind up in any one of countless other machine types) - which generally means how they are laid out in memory. The whole concept of C declarations is not rich enough to really deal with this properly. For each field in the header, one absolutely needs to be able to separately specify the syntax (e.g. size in bits) and semantics (unsigned integer, etc). And if you want the code to be portable, so that one set of sources will compile to working code on several different architctures, it gets worse. Device registers, already mentioned, often only have to run on one type of machine, but having protocol implementions run on a number of different machine types is really common. I came up with a way to do this, without _any_ #ifdefs (which I don't like, for a reason I won't get into) in most source files. Dealing with byte order issues was similarly dealt with (one can't deal with it just in types, really, without making the type specification, and the language, somewhat complicated). I know later C's got better about richer variable semantics and syntax selection than the circa 1985 ones I was working with, but I don't think it was ever made completely simple and orthogonal (e.g. 'signed/unsigned/boolean/etc char/short/long/quad/word/etc') as it should have been.

Language-lawyers' field day (was Any UNIX With No C In Userland?)

by Douglas McIlroy

> Everything that can possibly be represented in a machine > register with all bits clear shows up as an integral zero literal. > '\0' == 0 == nullptr == struct { } == union { } Well, some things. 0.0f and other floating-point zero constants are represented by all-zero words (of various sizes) and are not integral constants. NULL does not "show up as an integral zero literal". 0==NULL is true only because 0 can be converted to NULL. Getting really lawyerly, one can cook up any number of bizarre "things that can possibly be represented" by an all-zero word, for example (char[4]){0,0,0,0}, and have no representation as an integral constant. Only 3 of the 5 examples fit the description of possibly being represented by an all-zero word. struct{} and union{} are gnu extensions with size zero. Even if you accept them as C, they have no machine representation and cannot be cast to int. The null pointer makes the list only thanks to the weasel-word "possibly". Although 0 can be cast to the null pointer, the result of casting a null pointer to int depends on its unspecified machine representation. Zero, of course, is a good choice because it's easy to test for, and is easy to omit from virtual address spaces. Doug
