I just thought that the function would be ever so slightly simpler if it had the following structure roughly: ``` if (Arg *A = ...) { ThreadPointer = llvm::StringSwitch... ; if (!Invalid) return ThreadPointer; if (empty) D.Diag(); else D.Diag(); return Invalid; } return ReadTPMode::Soft; ``` And probably is also slightly closer to the coding standard described in https://llvm.org/docs/CodingStandards.html#use-early-exits-and-continue-to-simplify-code But this is a really minor comment. https://reviews.llvm.org/D34878 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
