<bofh> egg|zzz|egg: ?
<kmath> <calfromkansas> Creating this #set of 6 24x24 #celestialobjects reminded me of a choice few arcade shmups 🙃 @Pixel_Dailies… https://t.co/4hOfJmWI3r
<egg|zzz|egg> bofh: see backlog, I had a question about aliasing
<bofh> sec.
<bofh> egg|zzz|egg: I don't see it, got an approximate timestamp
<kmath> <Helios748> She really likes when I wear this hoodie https://t.co/b8YtBmGhNo
<egg|zzz|egg> bofh: <egg|zzz|egg> bofh: so what are the restrictions on aliasing in FORTRAN? is it just that arguments can't alias, or are there other things that can't alias
<kmath> <sadserver> twitch plays s3 bucket policies
<bofh> egg|zzz|egg: that was from, like, yesterday :P and I responded: I think it's just arguments, but honestly that suffices, since you can just put all your allocation into your PROGRAM statement and then pass the allocated arrays to your actual function and yeah.
<egg|zzz|egg> huh, seems I didn't get the response
<awang> I don't have it in my scrollback either
<egg|zzz|egg> bofh: Ada has this neat things where you need to declare a thing aliased to be able to alias it
<awang> logs.tmsp.io doesn't seem to have it either
<awang> More languages need to adopt Ada features >:(
<egg|zzz|egg> bofh: also Ada allows actually doing things on the heap (including returning records with discriminant etc.)
<egg|zzz|egg> (Ada is terrible at heap-allocated things because type-level pools are bad, but hey, it was designed in 79)
<egg|zzz|egg> (returning unconstrained base classes too!)
<egg|zzz|egg> s/on the heap/on the stack/
<Qboid> egg|zzz|egg meant to say: bofh: also Ada allows actually doing things on the stack (including returning records with discriminant etc.)
<egg|zzz|egg> meow
<iximeow> !wpn egg
* Qboid gives egg a triangulated unicode mace
<egg|zzz|egg> appropriate
<bofh> egg|zzz|egg: Fortran is pretty bad with heap-allocated things to the point where a good chunk of the codebase I work with actually calls out to a C function that calls mmap and returns the pointer address, which we then pass varying increments of to whatever the hell needs bigass arrays
<bofh> !wpn egg|zzz|egg
* Qboid gives egg|zzz|egg an adaptive 🐍
<bofh> !wpn iximeow
* Qboid gives iximeow a ½λ quabla
<bofh> where were my manners
<awang> bofh: Fortran version of C++ allocators?
<egg|zzz|egg> bofh: so Ada is either safe and memory pools (where things have lifetime tied to a scope, which is the scope of the access type), or unchecked_deallocation which is unsafe as the name indicates
<egg|zzz|egg> (all the unsafe things say "unchecked" in the name, so you can grep for it)
<egg|zzz|egg> unchecked_conversion!
<bofh> awang: erm, it's basically just mmap(NULL, a_few_thousand_MB, RW, MAP_ANON, -1, 0) and then passing the return of that with various increments to places :P
<bofh> I mean if that's what C++ allocators do then: A) cool, B) rofl
<egg|zzz|egg> ?
<egg|zzz|egg> ah replying to awang, missed that
<awang> bofh: I think that's what they do at least? Or at you can write one that does that, probably
<bofh> it's like the derpy simple thing
<awang> Oh
<awang> That reminds me
<awang> I found this really really old Fortran code sitting on one of the backup servers at work
<awang> Old enough that it still has the column 6 thing
<awang> Also, Clang can't release their Fortran frontend soon enough
<egg|zzz|egg> mrow
<bofh> awang: ifort, friend.
* UmbralRaptop wonders if spending too much time online can have uneggspected effects. Like turning someone into a cat.
<bofh> I mean being online is highly correlated with becoming a catgirl, so.
<UmbralRaptop> well, yes.
<iximeow> meow
* UmbralRaptop scritches iximeow.
<awang> bofh: Is gfortran worth using?
<awang> I don't think we have an ifort license any more
<awang> Or if we do, then it's on a computer that still uses VS 6
<bofh> awang: it's free for noncommercial use
<bofh> awang: alternatively, piss-easy to crack
<egg|zzz|egg> UmbralRaptop: meow?
<bofh> awang: gfortran is a garbage fire, but I guess usable if you have literally nothing else.
* UmbralRaptop pets egg|zzz|egg.
<awang> bofh: Oh, really? When did Intel start with the non-commercial user thing?
<awang> Is the free version limited compared to the paid one? Or the same?
<awang> Can you explain the "garbage fire" part? Actually curious here
<awang> Like every time that someone says that some program is only good for the compost, I want to know why
<awang> It's usually funny and informative. Good combo!
<bofh> awang: like at least 5 or 6 years ago, I recall starting with ifort in ~2010
<bofh> anyway the answer is simple: it usually, inexplicably, outputs worse assembly for arbitrary fortran than f2c followed by gcc on the .c does (optionally adding __restrict to pointers first), despite if anything, the opposite should be true.
<bofh> *maybe* this has finally changed for the better, but it was true as of still even a year ago.
<bofh> I don't even have a satisfactory answer for why, this defies common sense, sanity and compiler design.
<awang> Huh, I should download ifort then
<awang> ...That's quite impressive
<awang> gfortran doesn't seem to get enough use to warrant more time figuring that out, it seems?
<awang> ...I feel like I hear things similar to "defies common sense, sanity, and [something] design" disturbingly frequently when talking about GNU software
<bofh> Like I mean it *is* used often by the academic community when people don't want to use ifort and/or PGI Fortran (tho iirc the latter is being turned into an llvm Fortran frontend now?)
<awang> Right, I remember reading about PGI open-sourcing their front end
<awang> Or at least part of it
<awang> Maybe it'll be the competition gfortran needs
<awang> Like what clang did for gcc, from what I heard?
<bofh> Yeah, hopefully.

<egg|zzz|egg> bofh: yes but which bit thereof
<bofh> "Change the parallel_test_runner.cs to just pass unencoded strings when starting the test processes."
<bofh> using the W entrypoints is arguably correct and should've been done awhile ago
<egg|zzz|egg> bofh: yeah
<egg|zzz|egg> bofh: but, well, we didn't feel like doing i18n on the gtest thingies on a saturday evening
<egg|zzz|egg> I'll probably get annoyed by not being able to pass Чебышёв on the command line eventually and fix it
<egg|zzz|egg> bofh: we did check that it works if the test is called ρ so it's not actually CP1252 (it allows 0x81)
<bofh> ahh.
<bofh> and yeah, that's reasonable.
<egg|zzz|egg> bofh: note that "Change the parallel_test_runner.cs to just pass unencoded strings when starting the test processes." is also correct, albeit weirdly-worded (the bullet-point list is a conjunction not a disjunction)
<egg|zzz|egg> currently we encode UTF-8 and decode CP1252 and weep
<egg|zzz|egg> "unencoded" means you just pass a System.String and on the other side there's a wmain
<bofh> <@egg|unit_tests|egg> oh but the affine ordered hovel is called a "masure"
<bofh> <@egg|unit_tests|egg> that's a french word for, hovel basically
<bofh> <@egg|unit_tests|egg> sometimes they run out of words and they use french
