2010-12-09Use error_code instead of std::string* for MemoryBuffer.Michael J. Spencer
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121378 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
2010-11-23simplify the cache miss handling code, eliminating CacheMissing.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120038 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
2010-11-23don't allow remapping PTH file paths with -fworking-directory, theChris Lattner
client should just pass in absolute paths. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23now the FileManager has a FileSystemOpts ivar, stop threadingChris Lattner
FileSystemOpts through a ton of apis, simplifying a lot of code. This also fixes a latent bug in ASTUnit where it would invoke methods on FileManager without creating one in some code paths in cindextext. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120010 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Implement -working-directory.Argyrios Kyrtzidis
When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions. Addresses rdar://8583824. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118203 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-12Don't emit end-of-file diagnostics like "unterminated conditional" orDouglas Gregor
"unterminated string" when we're performing code completion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110933 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-27Add PTHLexer::LexEndOfFile() to emit diagnostics at end-of-file similar to ↵Ted Kremenek
those by Lexer::LexEndOfFile(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109486 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-12Switch PTHManager to using diagnostics for most errors.Daniel Dunbar
Also, always give errors on a token-cache PTH failure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86939 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84436 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-17Switch to llvm::HashString.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84375 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Add support for a chain of stat caches in the FileManager, rather thanDouglas Gregor
only supporting a single stat cache. The immediate benefit of this change is that we can now generate a PCH/AST file when including another PCH file; in the future, the chain of stat caches will likely be useful with multiple levels of PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84263 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-22PTHManager::Create():Ted Kremenek
- Make the Diagnostic::Level for PTH errors to be specified by the caller clang (driver): - Set the PTHManager diagnostic level to "Diagnostic::Error" for -include-pth (a hard error) and Diagnostic::Warning for -token-cache (we can still proceed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67462 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-21Add back warning about a PTH file not containing any identifiers, but don't makeTed Kremenek
it a hard error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-21Allow PTH files with no identifiers.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67423 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-20PTHManager::Create() now creates a PTHManager even if the PTH file contains noTed Kremenek
cached tokens. This is for use with -include-pth. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-19Add PTHManager::getOriginalSourceFile(), a method that returns the name of theTed Kremenek
original source file (if any) that was used to generate the PTH cache. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67343 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-23Move PTHStatCache within the anonymous namespace.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65348 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-19Fix another PTH warning that should not be a note.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65072 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-19Make PTH warnings actual warnings instead of 'notes'.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65071 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13PTH: Cache directory and negative 'stat' calls. This gives us a 1% ↵Ted Kremenek
performance improvement on Cocoa.h (fsyntax-only+PTH). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64490 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Add some boilerplate to the PTH file to prepare for the caching of stats for ↵Ted Kremenek
directories (and negative stats too). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64477 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-13Fix gcc warning: gcc correctly notes that const-qualifying the return Eli Friedman
type doesn't do anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64424 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Fix assertion when input is an empty string.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64397 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Re-enable PTH stat caching. All tests pass now.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64356 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Fix bad reading of bytes in ReadUnalignedLE64() (copy-paste error).Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64355 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12Temporarily disable PTH stat caching as it appears to be failing on some ↵Ted Kremenek
machines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64354 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-12PTH: Cache stat information for files in the PTH file. Hook up FileManagerTed Kremenek
to use this stat information in the PTH file using a 'StatSysCallCache' object. Performance impact (Cocoa.h, PTH): - number of stat calls reduces from 1230 to 425 - fsyntax-only: time improves by 4.2% We can reduce the number of stat calls to almost zero by caching negative stat calls and directory stat calls in the PTH file as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64353 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-11PTH: Have meta data be at the beginning of the PTH file, not the end.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64338 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-11PTH: Replace string identifier to persistent ID lookup with a hashtable. This isTed Kremenek
actually *slightly* slower than the binary search. Since this is algorithmically better, further performance tuning should be able to make this faster. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64326 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-11PTH: Don't emit the PTH offset of the IdentifierInfo string data as that data isTed Kremenek
referenced by other tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64304 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-10PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file ↵Ted Kremenek
with an on-disk chained hash table. This data structure is implemented using templates, and will be used to replace similar data structures. This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64245 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Add more PTH diagnostics for invalid PTH files, etc.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63232 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Enhance PTHManager::Create() to take an optional Diagnostic* argument that ↵Ted Kremenek
can be used to report issues such as a missing PTH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63231 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27PTH: Use Token::setLiteralData() to directly store a pointer to cached ↵Ted Kremenek
spelling data in the PTH file. This removes a ton of code for looking up spellings using sourcelocations in the PTH file. This simplifies both PTH-generation and reading. Performance impact for -fsyntax-only on Cocoa.h (with Cocoa.h in the PTH file): - PTH generation time improves by 5% - PTH reading improves by 0.3%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63072 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Silence warning.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63054 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Add version number checking to PTH files.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63047 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Embed the offset of the PTH table inside the prologue of the PTH file. This ↵Ted Kremenek
will help improve gradual versioning of PTH files instead of relying that the PTH table is at a fixed offset. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63045 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Check in the long promised SourceLocation rewrite. This lays theChris Lattner
ground work for implementing #line, and fixes the "out of macro ID's" problem. There is nothing particularly tricky about the code, other than the very performance sensitive SourceManager::getFileID() method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62978 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-23This is a follow-up to r62675:Chris Lattner
Refactor how the preprocessor changes a token from being an tok::identifier to a keyword (e.g. tok::kw_for). Instead of doing this in HandleIdentifier, hoist this common case out into the caller, so that every keyword doesn't have to go through HandleIdentifier. This drops time in HandleIdentifier from 1.25ms to .62ms, and speeds up clang -Eonly with PTH by about 1%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62855 91177308-0d34-0410-b5e6-96231b3b80d8
