Any ideas?
@mcourteaux it looks to me like the error you're seeing is coming from here: https://github.com/halide/Halide/blob/85a3b07fab4ce07a9747d645dd1274c3f1c29b44/src/CodeGen_PTX_Dev.cpp#L265-L267 I reverted this change, but I plan to reland soon. Once I do you'll need to update this code to reference the new intrinsic. https://github.com/llvm/llvm-project/pull/140615 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
