+# Community Call 2026-06-03
+
+## Agenda
+
+* Design docs and/or RFCs  
+  * [\[RFC\]\[flang\]\[cmake\]\[perf-training\] Optimize flang with PGO and BOLT](https://discourse.llvm.org/t/rfc-flang-cmake-perf-training-optimize-flang-with-pgo-and-bolt/90884)  
+    * Related PRs:  
+      1. [\[flang\]\[cmake\]\[perf-training\] Optimize flang with PGO and BOLT by pawosm-arm · Pull Request \#197947 · llvm/llvm-project · GitHub](https://github.com/llvm/llvm-project/pull/197947)  
+      2. [\[flang\]\[cmake\]\[perf-training\] Optimize flang with PGO and BOLT by pawosm-arm · Pull Request \#198863 · llvm/llvm-project · GitHub](https://github.com/llvm/llvm-project/pull/198863)  
+    * This centers on speeding up the performance of the compiler itself. The PRs constitute two differing approaches to it as described in the RFC.  
+    * Some concerns around CI infrastructure, but this work could provide a basis for later refinement.  
+    * Performance numbers presented in the RFC  
+    * Optimizing Flang and Clang concurrently, but that does create a link between the two that was previously not there.  Is this acceptable in this case?  
+    * Using check flang as a profiling codebase, some disk space issues, some transient GitHub CI issues  
+    * Looking to get this in before the next LLVM branch.  Thoughts?  
+  * [\[RFC\] Support for \-std=f2023](https://discourse.llvm.org/t/rfc-support-for-std-f2023/89608)  
+    * Related PR: [\#196410 Generalize \-pedantic to take an optional argument](https://github.com/llvm/llvm-project/pull/196410)   
+      1. Reviewers needed, as there are several different ways forward and detailed feedback is very much needed  
+    * Related Issue: [https://github.com/llvm/llvm-project/issues/196409](https://github.com/llvm/llvm-project/issues/196409)   
+    * Tarun \- If you generalize \-pedantic, is it intended to warn on every possible deviation from the standard?  Or just to make a best effort at it? (will post on RFC)  
+  * [\[RFC\]\[flang\] Add Floating-point trap handling support](https://discourse.llvm.org/t/rfc-flang-add-floating-point-trap-handling-support/90544)   
+    * Github issue: [https://github.com/llvm/llvm-project/issues/198657](https://github.com/llvm/llvm-project/issues/198657)   
+    *   
+  * [\[RFC\] Aggressive inlinging for OpenMP SIMD loops](https://discourse.llvm.org/t/rfc-aggressive-inlinging-for-openmp-simd-loops/90558)   
+    * Needs more input from the community  
+    *   
+  * [\[RFC\] Flang lowering for OpenMP metadirective](https://discourse.llvm.org/t/rfc-flang-lowering-for-openmp-metadirective/90338)  
+    * PR open for review: [https://github.com/llvm/llvm-project/pull/194424](https://github.com/llvm/llvm-project/pull/194424)   
+    *   
+  * [Changes to builtin modules](https://discourse.llvm.org/t/changes-to-builtin-modules/89072)   
+    * Has [broken apt.llvm.org packaging](https://github.com/llvm/llvm-project/issues/201304)  
+    * Keep on agenda for next meeting, as ramifications of merging the main PR are still developing  
+    * Some buildbots need to be updated to the new build  
+    * Issue with omp\_lib.h, but fix has already been merged
+
+* PRs of Note  
+  * *Reviewers needed*: Conditional args support \- semantics, [https://github.com/llvm/llvm-project/pull/195345](https://github.com/llvm/llvm-project/pull/195345)   
+    * Parser support has been merged, this is the next step of the process and needs reviewers  
+    * Still has only one approval/review, but as this is a significant feature this really needs review from more experienced developers too  
+  * *Reviewers needed:* [Fix POSIX.1/XPG checks in intrinsics-library.cpp\#201072](https://github.com/llvm/llvm-project/pull/201072)   
+  * *Reviewers needed:* Fortran 2023 ENUMERATION TYPEs  
+    * Related to Issue [\#183789](https://github.com/llvm/llvm-project/issues/183789)   
+    * PR stack beginning here: [https://github.com/llvm/llvm-project/pull/192651](https://github.com/llvm/llvm-project/pull/192651)   
+    * All PRs in stack are still open for review  
+  * *Review(er)s needed:* \[flang\]\[OpenMP\] Remove over-broad global scan for declare reduction symbols  
+    * [https://github.com/llvm/llvm-project/pull/200329](https://github.com/llvm/llvm-project/pull/200329)
