Argyrios Kyrtzidis 71731d6b05 Implement -working-directory.
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.

Douglas Gregor 5ef9e33137 Make the deserialization of macro definitions lazy, so that we can
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.

Douglas Gregor f86c939bff When de-serializing a type that is supposed to be canonical, call
getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

Chandler Carruth 0171815ae1 Improve the tracking of source locations for parentheses in constructor calls.
This adds them where missing, and traces them through PCH. We fix at least one
bug in the extents found by the Index library, and make a lot of refactoring
tools which care about the exact formulation of a constructor call easier to
write. Also some minor cleanups to more consistently follow the friend pattern
instead of the setter pattern when rebuilding a serialized AST.

Patch originally by Samuel Benzaquen.

Argyrios Kyrtzidis 65ad5691fd Put the mechanism in place to track modifications in an AST entity that were 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. WIP

Douglas Gregor 57756eabc9 When performing typo correction, look through the set of known
identifiers to determine good typo-correction candidates. Once we've
identified those candidates, we perform name lookup on each of them
and the consider the results. 

This optimization makes typo correction > 2x faster on a benchmark
example using a single typo (NSstring) in a tiny file that includes
Cocoa.h from a precompiled header, since we are deserializing far less
information now during typo correction.

There is a semantic change here, which is interesting. The presence of
a similarly-named entity that is not visible can now affect typo
correction. This is both good (you won't get weird corrections if the
thing you wanted isn't in scope) and bad (you won't get good
corrections if there is a similarly-named-but-completely-unrelated
thing). Time will tell whether it was a good choice or not.

Argyrios Kyrtzidis 0e88a565c0 Allow deserialization of just the fields of a record, when we want to iterate over them,
instead of deserializing the complete declaration context of the record.

Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration
that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods.
Fix this by allow deserialization of just the fields when we want to iterate over them.

2010-10-05 20:41:58 +00:00
Douglas Gregor 9b3932c0bc Fix a marvelous chained AST writing bug, where we end up with the
following amusing sequence:
  - AST writing schedules writing a type X* that it had never seen
  before
  - AST writing starts writing another declaration, ends up
  deserializing X* from a prior AST file. Now we have two type IDs for
  the same type!
  - AST writer tries to write X*. It only has the lower-numbered ID
  from the the prior AST file, so references to the higher-numbered ID
  that was scheduled for writing go off into lalaland.

To fix this, keep the higher-numbered ID so we end up writing the type
twice. Since this issue occurs so rarely, and type records are
generally rather small, I deemed this better than the alternative: to
keep a separate mapping from the higher-numbered IDs to the
lower-numbered IDs, which we would end up having to check whenever we
want to deserialize any type.

Fixes <rdar://problem/8511624>, I think.

-In ASTDeclReader::VisitFunctionDecl VisitRedeclarable should be called before using FunctionDecl's isCanonicalDecl()
-In ASTDeclReader::VisitRedeclarableTemplateDecl CommonOrPrev must be initialized before anything else.

Douglas Gregor a9aa29cf0b Implement libclang support for using declarations. Clang actually uses
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
  - Cursor visitation of the three AST nodes for using declarations
  - Proper source-range computation for these AST nodes
  - Using declarations have no USRs, since they don't actually declare
    any entities.

Ted Kremenek 0ef508d301 Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols
(and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in
an @interface declaration.  'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions.  The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

Douglas Gregor f9e43cef54 Improve location information in the representation of namespace
aliases. Previously, the location of the alias was at the "namespace"
keyword. Now, it's on the identifier being declared (as is the custom
for Clang), and we keep a separate source location for the "namespace"
keyword.

Also, added a getSourceRange() member function to NamespaceAliasDecl
to correctly compute the source range.

Finally, removed a bunch of setters from NamespaceAliasDecl and gave
ASTReaderDecl friendship so that it could set the corresponding fields
directly.

Argyrios Kyrtzidis 43b205796f Fix the memory leak of FloatingLiteral/IntegerLiteral.
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers.
Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with
the APFloat/APInt values will never get freed.
I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.

Argyrios Kyrtzidis d32ee89ea2 Fix an issue with writing to PCH another included PCH, introduced by the "using an AST on-disk hash table for name lookup" commit.
When including a PCH and later re-emitting to another PCH, the name lookup tables of DeclContexts
may be incomplete, since we now lazily deserialize the visible decls of a particular name.
Fix the issue by iterating over the un-deserialized visible decls and completing the lookup tables
of DeclContexts before writing them out.

Alexis Hunt dcfba7b35b Generate Attr subclasses with TableGen.
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.
