2012-12-11	Extend stat query APIs to explicitly specify if the query is for	Argyrios Kyrtzidis	1	-9/+11
	a file or directory, allowing just a stat call if a file descriptor is not needed. Doing just 'stat' is faster than 'open/fstat/close'. This has the effect of cutting down system time for validating the input files of a PCH. llvm-svn: 169831

2010-12-17	Replace all uses of PathV1::isAbsolute with PathV2::is_{absolute,relative}.	Michael J. Spencer	1	-1/+1

2010-12-02	attempt to fix a buildbot failure, apparently apache fails to build.	Chris Lattner	1	-1/+1

2010-11-24	Fix 2 problems with Chris Lattner's FileManager redesign on Windows.	Francois Pichet	1	-1/+1
	- FileEntry::operator= is needed on Win32. - There was an error in the S_ISDIR() macro. llvm-svn: 120079
2010-11-23	The final result of all this refactoring: instead of doing stat immediately	Chris Lattner	1	-3/+38
	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
2010-11-23	if we succeed in opening a directory but expected a file, ensure we don't	Chris Lattner	1	-1/+22
	leak a filedescriptor if a client ever starts returning one. llvm-svn: 120062
2010-11-23	change the 'is directory' indicator to be a null-or-not	Chris Lattner	1	-2/+28
	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. llvm-svn: 120060
2010-11-23	replicate a terrible hack to fix a build error on VC++	Chris Lattner	1	-0/+4
	llvm-svn: 120039
2010-11-23	simplify the cache miss handling code, eliminating CacheMissing.	Chris Lattner	1	-6/+1
	llvm-svn: 120038
2010-11-23	r120013 dropped passing in the precomputed file size to	Chris Lattner	1	-1/+0
	MemoryBuffer::getFile, causing us to pick up a fstat for every file. Restore the optimization. llvm-svn: 120032
2010-11-23	PCH files only cache successful stats. Remove the code that reads/writes	Chris Lattner	1	-1/+1
	the result code of the stat to/from the PCH file since it is always 0. llvm-svn: 120031
2010-11-23	rework the stat cache, pulling it out of FileManager.h into	Chris Lattner	1	-0/+40
	its own header and giving it some more structure. No functionality change. llvm-svn: 120030
