We already know that LLVM itself passes pointers to functions in many places, and they're not bugs. I mean, this isn't the first time someone's proposed that pointer->bool conversions are evil. :) I know this just came up on a mailing list somewhere recently (rsmith was involved in the rebuttal, as was I), but all I can find on Google is: https://groups.google.com/a/isocpp.org/d/msg/std-proposals/a3g9qXFVGCs/Wj40qj48H3wJ Anyway, the punch line I'm thinking of is something like ``` FooBar *FB = ...; LLVMAssert(FB, "expected fb to be set"); ``` but with whatever the real names are. Found a bunch of those when I wrote the diagnostic. And they're fairly solidly in the "not bugs" category. https://reviews.llvm.org/D45601 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
