2010-11-16Use an OwningPtr for the preamble buffer in ASTUnit. This plugs a leakDouglas Gregor
where we failed to free this buffer along one of the paths, and detangles the code a little. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119379 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-15Clean up some names and fix the handling of default sysroots on Windows andChandler Carruth
other platforms where the textual default of '/' isn't the system's root directory. We should probably still make the textual default platform specific, but this should avoid the particularly bad problem with the previous state: we applied a sysroot of '/' to '/usr/local/google' which added '//usr/local/include' to the windows header search path, a share on another machine named 'usr'. Oops. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119131 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
2010-11-11Improve ASTUnit's capture of diagnostics so that theDouglas Gregor
diagnostic-capturing client lives as long as the ASTUnit itself does. Otherwise, we can end up with crashes when we get a diagnostic outside of parsing/code completion. The circumstances under which this happen are really hard to reproduce, because a file needs to change from under us. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118751 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.

2010-10-24Put the mechanism in place to track modifications in an AST entity that were ↵Argyrios Kyrtzidis
committed after its initial creation/deserialization and store the changes in a chained PCH. The idea is that the AST entities call methods on the ASTMutationListener to give notifications of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes of the updated entity.

unrolling enough loops to show that an invariant doesn't hold. This fix is to increase the loop unrolling count to 4, which experiments show doesn't typically impact analysis time. The real fix is to modify the IdempotentOperationsChecker to suppress warnings where an analysis point could be preceded by a point where we gave up due to loop unrolling. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116769 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-08Fix three related, wily issues with the recompilation of precompiledDouglas Gregor
preambles: - When we rebuild a precompiled preamble, make sure to disable skipping anything in the main file; we may have had leftover preamble-skipping values in the lexer, which leads to very empty preamble. This is a correctness issue. - When we rebuild a precompiled preamble, clear out any prior state in the Diagnostic object. Otherwise, we might think that there were errors when we were building the preamble itself, and therefore reject the resulting preamble. This is mainly a performance issue. - Don't remove old remappings when digging out the remapping for the main file. Having the old mappings around does not hurt in the common case (later remappings will just overwrite them), and is important when we fail to find a preamble: we don't want to have removed the remapping, because we'll need it later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116041 91177308-0d34-0410-b5e6-96231b3b80d8
