New Revision: 157078

URL: http://llvm.org/viewvc/llvm-project?rev=157078&view=rev
Log:
Warn when we detect a valid dSYM file that is empty. This can happen when a dSYM file is created from a binary with no debug info, that has been stripped, or when the .o files are not available when the dSYM is created.
