2015-11-02[PTH] Fix data length used for stat cache entriesReid Kleckner1-1/+1
This came up in a boost build, which apparently uses PTH. This was broken in r187619 when we migrated it to uses llvm::fs instead of raw stat calls. Constructing a test case with a hash table collision in-tree is tough. Instead, I have a pending change to OnDiskChainedHashTable that asserts that the reported length of the data agrees with the data actually written. All of the existing in-tree tests find the bug with this assert. llvm-svn: 251828
2015-11-02Sink some PTHManager includes out of Preprocessor.hReid Kleckner1-0/+1
This reduces the number of .cpp files needed to be rebuilt after touching OnDiskHashTable from 120 to 21 for me. llvm-svn: 251810

2014-02-20Recommit virtual file systemBen Langmuir1-2/+2
Previously reverted in r201755 due to causing an assertion failure. I've removed the offending assertion, and taught the CompilerInstance to create a default virtual file system inside createFileManager. In the future, we should be able to reach into the CompilerInvocation to customize this behaviour without breaking clients that don't care. llvm-svn: 201818

2014-02-19Initial implementation of virtual file systemBen Langmuir1-2/+2
This adds the minimum virtual file system support to start migrating FileManager onto the VFS. Originally discussed here: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2014-February/035188.html Differential Revision: http://llvm-reviews.chandlerc.com/D2745 llvm-svn: 201618
2013-08-01Use llvm::sys::fs::UniqueID for windows and unix.Rafael Espindola1-23/+22
This unifies the unix and windows versions of FileManager::UniqueDirContainer and FileManager::UniqueFileContainer by using UniqueID. We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we want to be able to construct fake ones, and file_status has different members on unix and windows. What the patch does is: * Record only the information that clang is actually using. * Use llvm::sys::fs::status instead of stat and fstat. * Use llvm::sys::fs::UniqueID * Delete the old windows versions of UniqueDirContainer and UniqueFileContainer since the "unix" one now works on windows too. llvm-svn: 187619
2012-12-11Extend stat query APIs to explicitly specify if the query is forArgyrios Kyrtzidis1-2/+2
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
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth1-1/+1
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
