And today I learned that #Flang is real, a FORTRAN compiler.

🚀🎉 Huzzah, the earth-shattering #news is here: "flangnew" is now just "flang"! 🎨 It's a monumental leap for humanity, akin to swapping your mom's spaghetti sauce recipe with *the exact same recipe*. Expect a 33-minute epic saga on how this name change will revolutionize #Fortran #compilation... or not. 🙄👾

First official release of LLVM Flang

Wygląda na to, że ktoś stara się, żeby Flanga dało się skompilować. No wiecie, jak ktoś nie ma po 16G RAM-u na każdy proces kompilatora.

#LLVM #Flang

FYI, someone's actually putting an effort to try to make #Flang compileable. You know, without needing 16G RAM for a single compiler job.

#LLVM

Not that I'm promising anything but I've just sent the final patch to fix building #Flang on #Gentoo:

https://github.com/llvm/llvm-project/pull/126387

#LLVM #Fortran

Nie, żebym coś obiecywał, ale właśnie wysłałem ostatnią łatkę, która powinna naprawić budowanie Flanga na #Gentoo:

https://github.com/llvm/llvm-project/pull/126387

#LLVM #Flang #Fortran

Fajne rzeczy dzieją się z #LLVM w #Gentoo:

1. Już o tym wspominałem, ale wszystkie paczki teraz siedzą w llvm-*/, więc łatwiej je znaleźć.
2. Wrzuciłem llvm-runtimes/offload, przywracając obsługę offloadowania #OpenMP (dla 19.1.6 wzwyż).
3. Wrzuciłem llvm-core/mlir, korzystając ze świeżutkiej biblioteki dynamicznej (dostępne w najnowszym snapshocie 20.x, do 19.x raczej nie wejdzie już).
4. Przy okazji zacząłem pracować nad Flangiem, ale nic nie obiecuję. Chciałbym chociaż na poziomie projektu wprowadzić obsługę biblioteki dynamicznej MLIR-a.
5. Wysłałem łatki do wsparcia samodzielnego budowania #ClangIR, więc jak wszystko dobrze pójdzie, od pierwszego dnia będzie nam działało.
6. Na przegląd poszła nowa eclass llvm-r2, ze znacznie lepszym wsparciem kompilacji skrośnej. https://public-inbox.gentoo.org/gentoo-dev/20241221160053.780079-1-mgorny@gentoo.org/T/#t
7. Powoli też pracuję nad poprawą wsparcia kompilacji skrośnej w samych paczkach LLVM, ale nie wiem, kiedy skończę. Chciałbym chociaż wyeliminować konieczność budowania drugiej pełnej kopii LLVM i Clanga na CBUILD, tylko po to, by skompilować Clanga.

Some recent #LLVM goodies in #Gentoo:

1. Well, I've said that already but all packages are now in llvm-*/, so they're easier to find.
2. I've added llvm-runtimes/offload, which restores the offloading functions of #OpenMP (available in 19.1.6+).
3. I've added llvm-core/mlir, now that it provides a proper dylib to link to (available in the most recent 20.x snapshot, no plans to backport to 19.x).
4. I've started working on #Flang too, but no promises. At the very least, I'd like to make it support #MLIR dylib upstream.
5. I've sent patches for standalone build support in #ClangIR, so hopefully it'll be ready for integration when it lands in mainstream.
6. I've sent a new llvm-r2 eclass for review, now with much cleaner support for cross-compilation scenarios. https://public-inbox.gentoo.org/gentoo-dev/20241221160053.780079-1-mgorny@gentoo.org/T/#t
7. I'm also slowly working on improving cross-compilation support for LLVM packages themselves, but no ETA on this. At the very least, I'd like to remove the necessity of building another complete copy of LLVM+Clang for CBUILD to compile #Clang.

Found a very interesting #Chess variant called #Flang. It has only a handful of tightened up rules and the gameplay is great!

@rofirrim Don't see enough #flang posts

Debugging flang in gdb be like.

@fclc As of today, I can compile and link our code with #flang-new 🎉.
Running crashes at the first call to `omp_get_num_procs()`, but I can deal with that later.

(FAO @jplehr )

#Flang-New can officially compile the alpha branch of our primary in house library 🙌 🎉

#flang (the #Fortran #LLVM front-end) is an amazing piece of software but it is built on a heavy piece of C++ infrastructure that is very resource hungry to compile.

I am a bit worried this is an actual deterrent for contributions and it is unintentionally gatekeeping flang to large organisations that can access to big hardware.

Building a modern #compiler infrastructure is never trivial. Building #flang is too arduous (even in Release mode).

The program and schedule for the #fosdem 2023 #llvm devroom has been published! See https://fosdem.org/2023/schedule/track/llvm/
Presentation topics include #sycl, #compiler-rt, reducing global state, #mlir, experience of a downstream project tracking newer LLVM versions, #c2, #flang, and C/C++ embedded toolchains.

#LLVM's #Flang Compiler Adds -Ofast & -ffast-math Support

You can try #Fortran with online #compilers:
- On the Fortran Playground https://play.fortran-lang.org/ you can learn Fortran by compiling (and editing) various examples.
- On Godbolt Compiler Explorer https://godbolt.org/, you can use several versions of #GFortran, Intel #ifort, Intel #ifx and #Flang. And you can read the assembler code.
- On https://dev.lfortran.org/ you can play with the #LFortran compiler (development in progress) and see its intermediate representations.

Time to finally deliver my promise: I'm starting to seriously work on packaging #MLIR and #Flang for #Gentoo. For now, we're going to go with BUILD_SHARED_LIBS=ON, until upstream is ready with the final dylib API.
