[Nicolai Hähnle via Phabricator via llvm-commits]

nhaehnle added inline comments.


================
Comment at: llvm/utils/TableGen/RegisterInfoEmitter.cpp:101-109
+static std::string getLegalCName(std::string Name) {
+  static const char legal_elements[] =
+    "_abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
+  std::string::size_type pos = 0;
+  while ((pos = Name.find_first_not_of(legal_elements, pos)) !=
+         std::string::npos)
+    Name.replace(pos, 1, "_");
----------------
Is there no pre-existing way of doing this in TableGen? If not, why is this needed in the first place?
