2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie

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
2010-11-03Implement -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.

2010-04-05Clarify the ownership semantics of the Diagnostic object used byDouglas Gregor
ASTUnit. Previously, we would end up with use-after-free errors because the Diagnostic object would be creating in one place (say, CIndex) and its ownership would not be transferred into the ASTUnit.

incompatibility and show where the structural differences are.

Otherwise, having a warning/error printed via one Diagnostic and its note printed on the other Diagnostic could cause the note to be suppressed. - Implemented import functionality for IntegerLiteral (along with general support for statements and expressions) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95900 91177308-0d34-0410-b5e6-96231b3b80d8
