2010-11-24Fix 2 problems with Chris Lattner's FileManager redesign on Windows.Francois Pichet
- FileEntry::operator= is needed on Win32. - There was an error in the S_ISDIR() macro. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120079 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23The final result of all this refactoring: instead of doing stat immediatelyChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120066 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23if we succeed in opening a directory but expected a file, ensure we don'tChris Lattner
leak a filedescriptor if a client ever starts returning one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120062 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23change the 'is directory' indicator to be a null-or-notChris Lattner
pointer that is passed down through the APIs, and make FileSystemStatCache::get be the one that filters out directory lookups that hit files. This also paves the way to have stat queries be able to return opened files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120060 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-23r120013 dropped passing in the precomputed file size to Chris Lattner
MemoryBuffer::getFile, causing us to pick up a fstat for every file. Restore the optimization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120032 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23PCH files only cache successful stats. Remove the code that reads/writes Chris Lattner
the result code of the stat to/from the PCH file since it is always 0. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23rework the stat cache, pulling it out of FileManager.h intoChris Lattner
its own header and giving it some more structure. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120030 91177308-0d34-0410-b5e6-96231b3b80d8
