This method is/will be implemented by the derived classes `DirectXTargetCodeGenInfo` and `CommonSPIRTargetCodeGenInfo`. The default implementation should return `nullptr`, the same as the default implementation of `getHLSLType` on the `TargetCodeGenInfo` class. `nullptr` means "I don't know who to convert this type". https://github.com/llvm/llvm-project/pull/124886 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
