# Combined Call 2026-04-08
|
||
|
||
## Agenda
|
||
|
||
* Design docs and/or RFCs
|
||
* [\[RFC\] Helping the new contributors to create better contributions](https://discourse.llvm.org/t/rfc-helping-the-new-contributors-to-create-better-contributions/90213)
|
||
* No discussion at this time
|
||
* [\[RFC\] Support for More Than 15 Array Dimensions in Flang](https://discourse.llvm.org/t/rfc-support-for-more-than-15-array-dimensions-in-flang/90423)
|
||
* It does not appear that there is a real-world use case for this functionality at this time that would justify the potential downsides.
|
||
* [\[RFC\] Alignment of global arrays](https://discourse.llvm.org/t/rfc-alignment-of-global-arrays/90397)
|
||
* Related issue: [\[Flang\] Bad alignment of globals in modules · Issue \#189069](https://github.com/llvm/llvm-project/issues/189069)
|
||
* Related PR: [https://github.com/llvm/llvm-project/pull/189709](https://github.com/llvm/llvm-project/pull/189709) (likely to be merged soon?)
|
||
* Should there be a command-line flag for this? Could specify different alignments this way (ex. 32 or 64\)
|
||
* Should it be determined by the user providing an architecture flag?
|
||
* We don’t want to set a default alignment that conflicts with the architecture
|
||
* How to handle the case of conflicting command line args?
|
||
* Consider library compatibility
|
||
* [\[RFC\] Flang lowering for OpenMP metadirective](https://discourse.llvm.org/t/rfc-flang-lowering-for-openmp-metadirective/90338)
|
||
* No discussion at this time
|
||
* [\[RFC\] preserve logical operations in the IR for reductions](https://discourse.llvm.org/t/rfc-flang-preserve-logical-operations-in-the-ir-for-reductions/90470)
|
||
* No discussion at this time
|
||
* [\[RFC\] Fortran 2023 ENUMERATION TYPEs](https://discourse.llvm.org/t/rfc-fortran-2023-enumeration-types/90255)
|
||
* Related to Issue [\#183789](https://github.com/llvm/llvm-project/issues/183789)
|
||
* Had initial prototype, refactoring now after RFC discussion and PR feedback
|
||
* PRs (\~10) should start coming in later this week
|
||
* Creating a new document "OpenMP-extensions"?
|
||
* [https://github.com/llvm/llvm-project/pull/186696\#discussion\_r2939508874](https://github.com/llvm/llvm-project/pull/186696#discussion_r2939508874)
|
||
* Has also been discussed in the OpenMP call, general consensus is to move forward with this
|
||
* Will this include “not yet implemented” features?
|
||
* [\[OpenMP\] Misspelling of \-Wopen-mp](https://discourse.llvm.org/t/openmp-misspelling-of-wopen-mp/90196)
|
||
* PR: [https://github.com/llvm/llvm-project/pull/188434](https://github.com/llvm/llvm-project/pull/188434)
|
||
* There do not seem to be objections, but what is the deprecation period?
|
||
* 2 releases, is it enough? Yes
|
||
* [\[RFC\] Adding conditional expressions in Flang (F2023)](https://discourse.llvm.org/t/rfc-adding-conditional-expressions-in-flang-f2023/89869)
|
||
* Has been split into two PRs
|
||
* Parsing/Semantics: [https://github.com/llvm/llvm-project/pull/186489](https://github.com/llvm/llvm-project/pull/186489) **(has 4 approvals, needs merge)**
|
||
* Lowering: [https://github.com/llvm/llvm-project/pull/186490](https://github.com/llvm/llvm-project/pull/186490) (has 2 approvals, awaiting 1 review)
|
||
* Tests added to test suite: [https://github.com/llvm/llvm-test-suite/pull/369](https://github.com/llvm/llvm-test-suite/pull/369)
|
||
* [\[Flang\]\[Affine\] Linearized array access in \-promote-to-affine causes false dependence and blocks loop tiling](https://discourse.llvm.org/t/flang-affine-linearized-array-access-in-promote-to-affine-causes-false-dependence-and-blocks-loop-tiling/89927)
|
||
* Several paths forward have been suggested, **please comment on the post to help guide this new contributor**
|
||
* [Changes to builtin modules](https://discourse.llvm.org/t/changes-to-builtin-modules/89072)
|
||
* Community could help by commenting and highlighting how important this change is. Would relieve a lot of annoyance and this is holding up Flang community progress.
|
||
* Initial PR has been merged. Additional PR: [https://github.com/llvm/llvm-project/pull/171610](https://github.com/llvm/llvm-project/pull/171610)
|
||
* Main PR (from which the other two were extracted): [https://github.com/llvm/llvm-project/pull/171515](https://github.com/llvm/llvm-project/pull/171515)
|
||
* Still needs some working with reviewers, will contact directly at EuroLLVM next week
|
||
|
||
* PRs of Note
|
||
* Support for rank-1 integer array expressions in declarations (assumed-shape and explicit-shape) and allocate statements
|
||
* Has been broken up, reviewers needed.
|
||
* These should now be self-contained parser support PRs. Short design description is given in the GitHub Issue, [https://github.com/llvm/llvm-project/issues/178071](https://github.com/llvm/llvm-project/issues/178071)
|
||
* [https://github.com/llvm/llvm-project/pull/188445](https://github.com/llvm/llvm-project/pull/188445)
|
||
* [https://github.com/llvm/llvm-project/pull/188446](https://github.com/llvm/llvm-project/pull/188446)
|
||
* [https://github.com/llvm/llvm-project/pull/188447](https://github.com/llvm/llvm-project/pull/188447)
|
||
* PR related to pointer assignment coming
|
||
* Document RFC best practices \- [PR \#190836](https://github.com/llvm/llvm-project/pull/190836)
|
||
* \[flang\]\[OpenMP\] Support user-defined declare reduction with derived types [https://github.com/llvm/llvm-project/pull/190288](https://github.com/llvm/llvm-project/pull/190288) \- could use AMDGPU code reviews
|
||
* Michael Klemm asked to be tagged to review
|
||
|
||
* Issues of Note
|
||
* None at this time
|
||
|
||
* FYI
|
||
* [LLVM 22.1.3 Released\!](https://discourse.llvm.org/t/llvm-22-1-3-released/90467)
|
||
|
||
* Other topics as time allows
|
||
* Next J3 meeting is scheduled for the week of June 15th in Coventry, UK
|
||
* Best practice for PR that is dependent on someone else’s (unmerged) PR?
|
||
* Could make it a part of a PR stack in some cases (LLVM user branches)
|
||
* Otherwise, suggest making a draft PR and linking to the dependent one
|
||
* Peter Klausler has retired. Thank you for all your hard work getting Flang started and ensuring it’s quality\!\!
|
||
* Reviews that would normally have gone to him should be directed to either Eugene Epshteyn or Jean Perier
|
||
* AMD and NVIDIA are hiring for Fortran compiler people
|
||
|
||
## Details
|
||
|
||
* Consists of over **744,000** lines of code, documentation, build files, and test
|
||
* To date, over **12,082** commits have been made to Flang
