SourceManager::getInstantiationLoc() can return a SourceLocatin with an invalid FileID on invalid code. Fixes <rdar://problem/9164623>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128139 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-21Improve crash recovery cleanup to recovery CompilerInstances during crash ↵Ted Kremenek
recovery. This was a huge resource "root" during crashes. This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128011 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-08Add 'OverridenFilesKeepOriginalName' field in SourceManager which if true ↵Argyrios Kyrtzidis
the SourceManager should report the original file name for contents of files that were overriden by other files, otherwise it should report the name of the new file. Default is true. Also add similar field in PreprocessorOptions and pass similar parameter in ASTUnit::LoadFromCommandLine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127289 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-05Currently we can only remap a file by creating a MemoryBuffer and replacing ↵Argyrios Kyrtzidis
the file contents with it. Allow remapping a file by specifying another filename whose contents should be loaded if the original file gets loaded. This allows to override files without having to create & load buffers in advance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127052 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Teach SourceManager::getLocation() how to cope with a source fileDouglas Gregor
whose inode has changed since the file was first created and that is being seen through a different path name (e.g., due to symlinks or relative path elements), such that its FileEntry pointer doesn't match a known FileEntry pointer. Since this requires a system call (to stat()), we only perform this deeper checking if we can't find the file by comparing FileEntry pointers. Also, add a micro-optimization where we don't bother to compute line numbers when given the location (1, 1). This improves the efficiency of clang_getLocationForOffset(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124800 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-30When loading a precompiled preamble, use the file ID of theDouglas Gregor
precompiled preamble as the "main" source file's file ID within the source manager. This makes compiling with a precompiled preamble produce the same source locations as when compiling without the precompiled preamble; prior to this change, we ended up with different file IDs for source locations within the precompiled preamble vs. those after the precompiled preamble, even for entities (e.g., preprocessing entities) in the same file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120390 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
2010-11-18Refactoring of Diagnostic class.Argyrios Kyrtzidis
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119730 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-12Make sure to always check the result ofDouglas Gregor
SourceManager::getPresumedLoc(), so that we don't try to make use of an invalid presumed location. Doing so can cause crashes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118885 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

2010-09-22Implement -Wpadded and -Wpacked.Argyrios Kyrtzidis
-Wpadded warns when undesired padding is introduced in a struct. (rdar://7469556) -Wpacked warns if a struct is given the packed attribute, but the packed attribute has no effect on the layout or the size of the struct. Such structs may be mis-aligned for little benefit. The warnings are emitted at the point where layout is calculated, that is at RecordLayoutBuilder. To avoid calculating the layouts of all structs regardless of whether they are needed or not, I let the layouts be lazily constructed when needed. This has the disadvantage that the above warnings will be emitted only when they are used for IR gen, and not e.g with -fsyntax-only: $ cat t.c struct S { char c; int i; }; void f(struct S* s) {} $ clang -fsyntax-only -Wpadded t.c $ clang -c -Wpadded t.c -o t.o t.c:3:7: warning: padding struct 'struct S' with 3 bytes to align 'i' [-Wpadded] int i; ^ 1 warning generated. This is a good tradeoff between providing the warnings and not calculating layouts for all structs in case the user has enabled a couple of rarely used warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114544 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-31Implement dependency analysis for the precompiled preamble. If any ofDouglas Gregor
the files in the precompiled preamble have changed since it was build, force the preamble to be rebuilt. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109937 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-26Introduce basic support for loading a precompiled preamble whileDouglas Gregor
reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109445 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-07reimplement the caching in the SourceManager::isBeforeInTranslationUnit()Chris Lattner
method to be correct. Right now it correctly computes the cache, then goes ahead and computes the result the hard way, then asserts that they match. Next I'll actually turn it on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103231 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20push some source location information down through the compiler,Chris Lattner
into ContentCache::getBuffer. This allows it to produce diagnostics on the broken #include line instead of without a location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101939 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-16Teach SourceManager's content cache to keep track of whether itsDouglas Gregor
buffer was invalid when it was created, and use that bit to always set the "Invalid" flag according to whether the buffer is invalid. This ensures that all accesses to an invalid buffer are marked invalid, improving recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98690 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Introduce optional "Invalid" parameters to routines that invoke theDouglas Gregor
SourceManager's getBuffer() and, therefore, could fail, along with Preprocessor::getSpelling(). Use the Invalid parameters in the literal parsers (string, floating point, integral, character) to make them robust against errors that stem from, e.g., PCH files that are not consistent with the underlying file system. I still need to audit every use caller to all of these routines, to determine which ones need specific handling of error conditions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98608 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-15Introduce a new BufferResult class to act as the return type ofDouglas Gregor
SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-28Introduce serialization and deserialization of diagnostic informationDouglas Gregor
so that CIndex can report diagnostics through the normal mechanisms even when executing Clang in a separate process. This applies both when performing code completion and when using ASTs as an intermediary for clang_createTranslationUnitFromSourceFile(). The serialized format is not perfect at the moment, because it does not encapsulate macro-instantiation information. Instead, it maps all source locations back to the instantiation location. However, it does maintain source-range and fix-it information. To get perfect fidelity from the serialized format would require serializing a large chunk of the source manager; at present, it isn't clear if this code will live long enough for that to matter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94740 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-02Extend the source manager with the ability to override the contents ofDouglas Gregor
files with the contents of an arbitrary memory buffer. Use this new functionality to drastically clean up the way in which we handle file truncation for code-completion: all of the truncation/completion logic is now encapsulated in the preprocessor where it belongs (<rdar://problem/7434737>). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90300 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-27Load most of the source manager's information lazily from the PCHDouglas Gregor
file. In particular, only eagerly load source location entries for files and for the predefines buffer. Other buffers and macro-instantiation source location entries are loaded lazily. With the Cocoa-prefixed "Hello, World", we only load 815/26555 source location entities. This halves the amount of user time we spend in this "Hello, World" program with -fsyntax-only (down to .007s). This optimization is part 1 of 2 for the source manager. This eliminates most of the user time in loading a PCH file. We still spend too much time initialize File structures (especially in the calls to stat), so we need to either make the loading of source location entries for files lazy or import the stat cache from the PTH implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70196 91177308-0d34-0410-b5e6-96231b3b80d8
