followed by an open for every source file we open, probe the file system with 'open' and then do an fstat when it succeeds. open+fstat is faster than stat+open because the kernel only has to perform the string->inode mapping once. Presumably it gets faster the deeper in your filesystem a lookup happens. For -Eonly on cocoa.h, this reduces system time from 0.042s to 0.039s on my machine, a 7.7% speedup. llvm-svn: 120066
