[RFC] A New Divergence Analysis for LLVM
...8: Invariant } -- The new DivergenceAnalysis -- The proposed DivergenceAnalysis detects divergence in unstructured, reducible control flow and nested divergent loops. The implementation provides light-weight frontends for use in VPlan (LoopDivergenceAnalysis) and the analysis of GPU kernels (GPUDivergenceAnalysis). Both frontends build on a single, shared implementation of the actual divergence analysis algorithm. Apart from solving current issues with divergence detection in LLVM, the new analysis will enable the adoption of advanced vectorization techniques in VPlan that are already implemented in RV...

[RFC] Adding thread group semantics to LangRef (motivated by GPUs)
Strong agree with Mehdi, I am also not really sure what is the proposal at this point so it's hard to comment further. > There are a number of questions that I have. Do we need better machine descriptions so that various resources can be considered? Do we need the capability to reason about the machine state for the cross-lane operations to enable more optimizations? Are intrinsics the
