MS name mangling supports cache for first 10 distinct function arguments. The error was when non cached template type occurred twice (e.g. 11th and 12th). For such case in code there is another cache table TemplateArgStrings (for performance reasons). Then one '@' character at the end of the mangled name taken from this table was missing. For other cases the missing '@' character was added in the call to mangleSourceName(TemplateMangling) in the cache miss code, but the cache hit code didn't add it. This fixes a regression from r362560. Patch by Adam Folwarczny <adamf88@gmail.com>! Differential Revision: https://reviews.llvm.org/D68099 llvm-svn: 374543
