New Revision: 51972
URL: http://llvm.org/viewvc/llvm-project?rev=51972&view=rev
Log:
Support "<p>" as a short-hand for "id<p>". Here's a comment from GCC (the only documentation I could find on it).
/* Make "<SomeProtocol>" equivalent to "id <SomeProtocol>" - nisse at lysator.liu.se. */
This commit adds the parser magic. The type associated with <p> is still incorrect. Will discuss with Chris.
