similar to: Upstreaming Flang - postponed to Monday 23rd March

Can you elaborate on this? - to move the std::string/string_view/StringRef changes to pre-merge unless you're going to have someone dedicated to handling them post-merge (rather than "time permits"). The C vs C++ ism here is fairly strong and I'd like to get the C-style string handling out fairly quickly. I understood this item to be looking into replacing uses of std::string

Hi llvm-dev It's been a few weeks since I last gave an update on F18 and our progress on readying it for inclusion into the monorepo. Last time we discussed this the community challenged us to make the F18 source code look more like an LLVM project and to come up with a plan and schedule for completing this work (http://lists.llvm.org/pipermail/llvm-dev/2020-January/137989.html) The full

Hi Eric, Old flang certainly uses C-style strings but f18 uses std::string with few exceptions. Most of the instances in f18 of “char *” aren’t really strings in the C sense – they’re not null terminated and are really just pointers into raw or cooked source files/streams. I can’t think of an instance where the compiler dynamically allocates an array of characters and uses it as a C string. -

Hi all Thanks for all the replies and engagement on this issue. First point, given the state of discussions today I would like to propose that we don't start the merge at 10:00 GMT on Monday 13th as proposed and we delay by at least 24 hours until after the scheduled F18 technical call on Monday afternoon. In order to help compile a plan of action, I've tried to compile a list of the

Hi Eric, Renato Thanks again for the engagement and challenge on this, it is really useful feedback to know what we need to do to get F18 into the project in a way that everyone is happy with. I have tried to give timelines on the points addressed below where I can today. Clearly we need to do some work on points 8-11, but are the above plans/answers to points 1-7 sufficient at this stage and

Hi all F18 merging has finished so commit access should be back to normal.

Attached is the log. I'm building with: clang version 10.0.0 (https://github.com/llvm/llvm-project/ 3a6da1122b990386edeba0987d0d1fdc9c8dc53d) Target: x86_64-unknown-linux-gnu Thread model: posix On some Ubuntu-like distribution. I also ran with ASAN once and it found a bunch of leaks in bin/tco. Best, -- Mehdi On Tue, Apr 7, 2020 at 4:36 AM Richard Barton <Richard.Barton at

Hi Mehdi, I can't replicate those failures at my end, could you let me know what OS, compiler and CMake flags you're using so I can try and reproduce? Thanks!

Hi llvm-dev We believe we have completed enough of the agreed pre-upstreaming changes to start talking about merging F18 into LLVM. The live status is tracked at [1]. There are a few details that we have not managed to hammer out and we propose to tackle inside the LLVM monorepo. I have put a summary of these at the bottom of this mail. Does anyone have any objections to flang being merged into

Hal, Eric, Johannes, David and Peter, I lead the development of OpenMP for AMD GPUs and work with others at AMD who support OpenMP on AMD CPUs. On behalf of our development teams, we greatly appreciate your efforts to move the development of flang into a subproject in the llvm-project repository and to integrate this development effort into the overall LLVM development community. Like most

Hi All, As discussed before Christmas, this is a reminder that we intend to merge flang on the 13th January (next Monday) before the llvm-10 branch. At the moment I'm proposing to do it at 10am GMT. I can be flexible on this point if it requires close coordination with anyone in another timezone, just let me know. Previous discussion was in [llvm-dev] Flang landing in the monorepo

I have concerns about the design of flang versus other front ends, the lack of llvm based library use, and a number of other things that I tried to enumerate in previous emails. I don't know if anything has changed and the responses I got

Hi Eric, Apologies, I failed to disambiguate clearly, because there are multiple projects named flang. I was referring to the "new" flang, whose repository is currently found at https://github.com/flang-compiler/f18. It will land in the monorepo under a directory called "/flang/". f18 has been approved to join, for reference see "[llvm-dev] f18 is accepted as part of

Hi All, The flang project (a Fortran compiler) is getting ready to join the monorepo. We intend to preserve the existing history by rewriting the existing commits as a linear series of commits on top of llvm-project. I understand the flang community would like to do this before the LLVM 10 branch in due in mid January, so please speak up soon if you see anything needing fixing in what I
