[PATCH] D65942: Disallow implicit conversion from pointers to bool in llvm::toStringRef

[David Blaikie via Phabricator via llvm-commits]

dblaikie added inline comments.


================
Comment at: lldb/source/Symbol/TypeSystem.cpp:331
           "TypeSystem for language " +
-              llvm::toStringRef(Language::GetNameForLanguageType(language)) +
+              llvm::StringRef(Language::GetNameForLanguageType(language)) +
               " doesn't exist",
----------------
Perhaps Language::GetNameForLanguageType should return StringRef to start with?

(& guessing there should be an lldb test case demonstrating this fix?)


================
Comment at: llvm/include/llvm/ADT/StringExtras.h:52-53
 /// Construct a string ref from a boolean.
-inline StringRef toStringRef(bool B) { return StringRef(B ? "true" : "false"); }
+template <typename T>
+typename std::enable_if<std::is_same<T, bool>::value, StringRef>::type
+toStringRef(T B) {
----------------

Sure, something like "ensure only bools are accepted here to avoid surprising implicit conversion to bool (for ints, pointers, etc)" if you like.
