* Implement caching of stat() calls for precompiled headers, which isDouglas Gregor2009-04-271-0/+18

* FileManager:Ted Kremenek2009-02-121-6/+4
| | | | | | | | | - set the 'StatSysCallCache' object using a setter method instead of FileManager's constructor. This allows the cache to be installed after the FileManager object is created. - Add 'file mode' to FileEntry (useful for stat caching) llvm-svn: 64351

* Add lightweight shim "clang::StatSysCallCache" that caches 'stat' system callsTed Kremenek2009-02-121-8/+10
| | | | | | | | | | for use by FileManager. FileManager now takes a StatSysCallCache* in its constructor (which defaults to NULL). This will be used for evaluating whether or not caching 'stat' system calls in PTH is a performance win. This shim adds no observable performance impact in the case where the 'StatSysCallCache*' is null. llvm-svn: 64345

lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. llvm-svn: 48402
