2010-12-15Fix diagnostic pragmas.Argyrios Kyrtzidis
Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state. Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect a lot of places, like C++ inline methods, template instantiations, the lexer, etc. Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location. Fixes rdar://8365684. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121873 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.

2010-11-23now the FileManager has a FileSystemOpts ivar, stop threadingChris Lattner

2010-11-20Revert r119838 "Don't warn for empty 'if' body if there is a macro that ↵Argyrios Kyrtzidis

2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein
than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere.

2010-11-06Add PPCallbacks for #if/#ifdef/etc.Craig Silverstein
The callback info for #if/#elif is not great -- ideally it would give us a list of tokens in the #if, or even better, a little parse tree. But that's a lot more work. Instead, clients can retokenize using Lexer::LexFromRawLexer(). Reviewed by nlewycky. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118318 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

load identifiers without loading their corresponding macro definitions. This is likely to improve PCH performance slightly, and reduces deserialization stack depth considerably when using preprocessor metaprogramming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117750 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19Really^2 fix <rdar://problem/8361834>, this time without crashing.Ted Kremenek
Now MICache is a linked list (per the FIXME), where we tradeoff between MacroInfo objects being in MICache and MIChainHead. MacroInfo objects in the MICache chain are already "Destroy()'ed", so they can be reused. When inserting into MICache, we need to remove them from the regular linked list so that they aren't destroyed more than once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116869 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19Really fix: <rdar://problem/8361834> MacroInfo::AddTokenToBody() leaks memoryTed Kremenek
The problem was not the management of MacroInfo objects, but that when we recycle them via the MICache the memory of the underlying SmallVector (within MacroInfo) was not getting released. This is because objects stashed into MICache simply are reused with a placement new, and never have their destructor called. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116862 91177308-0d34-0410-b5e6-96231b3b80d8
