```suggestion ``<x>`` parameter specifies the maximum number of work groups in the x dimension. ``` Also, we should be more clear/elaborate more what `x`, `y`, and `z` dimensions mean here. One thing I note is that `OpenCL` (IIRC?) actually reverses these? So it is VERY important that we document both order and meaning explicitly. https://github.com/llvm/llvm-project/pull/79035 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
