The first LLVM Women in Compilers and Tools (WiCT) meetup will be held in March. Please fill out the form to show interest and indicate the preferred date and time slot.
The agenda is now available for the EuroLLVM 2026.
According to the LLVM Calendar in the coming week there will be the following:
- Office hours with the following hosts: Aaron Ballman, Alexey Bader, Alina Sbirlea, Johannes Doerfert,
- Online sync-ups on the following topics: formal specification, CalngIR upstreaming, LLVM alias analysis, pointer authentication, Flang, SPIR-V, RISC-V, LLVM libc, HLSL, LLVM libc math.
- For more details see the LLVM calendar, getting involved documentation on online sync ups and office hours.
On the forums
-
Meeting notes from the most recent LLVM project council meeting are now available.
-
Andrzej Warzynski shared a public service announcement that the default behaviour of the WrapFuncinClassPass for EmitC will change.
-
Michael Kruse started a discussion on the warnings suppression policy for flang.
-
Sam Elliott is looking to understand the status of the IR outliner and remaining issues for it to be enabled more widely.
-
Tue Ly posted an RFC on using LLVM libc’s math routines for compiler-rt’s floating point builtins. One concern mentioned in the thread is whether there are any downstream compiler-rt users with only C compilers (i.e. would not be able to switch to a C++17 implementation of the builtins).
-
Jakub Kuderski asked about adding LLVM-specific clang-tidy checks.
-
Florian Hahn proposed intrinsics for speculative loads, aiming to help enable vectorisation of loops with early exits that have potentially faulting loads.
-
Some concerns were raised about current LLVM development practices, such as revising or clarifying the policy for ‘trivial’ patches committed without pre-commit review and concerns about some low-quality PRs being merged (and its relation to AI usage).
