If the source files referenced by a gcno file are missing, gcov outputs a coverage file where every line is simply /*EOF*/. This also occurs for lines in the coverage that are past the end of a file that is found. This change mimics gcov. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208149 91177308-0d34-0410-b5e6-96231b3b80d8
