Douglas Gregor fd4da71343 When determining which preprocessed entities to traverse in libclang,

Douglas Gregor 0192c234d5 Clean up the handling of template argument packs, especially in the
area of printing template arguments. The functionality changes here
are limited to cases of variadic templates that aren't yet enabled.

llvm-svn: 122250
2010-12-20 16:52:59 +00:00
Douglas Gregor d2fa766ad0 Introduce a new type, PackExpansionType, to capture types that are
pack expansions, e.g. given

  template<typename... Types> struct tuple;

  template<typename... Types>
  struct tuple_of_refs {
    typedef tuple<Types&...> types;
  };

the type of the "types" typedef is a PackExpansionType whose pattern
is Types&. 

This commit introduces support for creating pack expansions for
template type arguments, as above, but not for any other kind of pack
expansion, nor for any form of instantiation.

Douglas Gregor 0cdc832077 Eliminate the branching in QualType::getTypePtr() by providing a
common base for ExtQuals and Type that stores the underlying type
pointer. This results in a 2% performance win for -emit-llvm on a
typical C file, with 1% memory growth in the AST.

Note that there is an API change in this optimization:
QualType::getTypePtr() can no longer be invoked on a NULL
QualType. If the QualType might be NULL, use
QualType::getTypePtrOrNull(). I've audited all uses of getTypePtr() in
the code base and changed the appropriate uses over to
getTypePtrOrNull(). 

A future optimization opportunity would be to distinguish between
cast/dyn_cast and cast_or_null/dyn_cast_or_null; for the former, we
could use getTypePtr() rather than getTypePtrOrNull(), to take another
branch out of the cast/dyn_cast implementation.

Ted Kremenek 4ff4654893 Rework USR generation from CXCursors to use CXStringBufs
for the backing of generated USRs.  This optmizes
for the case when a client generates a sequence
of USRs in sequence, disposing of them soon
after generating them.  By using a string buffer,
we recycle malloc'ed memory instead of constantly
malloc'ing and copying strings.

2010-11-16 08:15:38 +00:00
Ted Kremenek 915542850b Change CXTranslationUnit to not directly cast to an ASTUnit*,
but to wrap both an ASTUnit and a "string pool"
that will be used for fast USR generation.

This requires a bunch of mechanical changes, as
there was a ton of code that assumed that CXTranslationUnit
and ASTUnit* were the same.

Along with this change, introduce CXStringBuf,
which provides an llvm::SmallVector<char> backing
for repeatedly generating CXStrings without a huge
amount of malloc() traffic.  This requires making
some changes to the representation of CXString
by renaming a few fields (but keeping the size
of the object the same).

Ted Kremenek 51df4d5596 Annotate CursorVisitor::VisitDataRecursive() with attribute 'noinline'.
Clang currently uses a ridiculous amount of stack space when inlining
this function, which can lead to premature stack overflows.

llvm-svn: 119281
2010-11-15 22:23:24 +00:00
Ted Kremenek ca817a3c0c "Fix" some unintentional fallout from converting
the Stmt* visitation in CursorVisitor to be
data-recursive.

Since AnnotationTokensWorker explicitly calls
CursorVisitor::VisitChildren(), it essentially
transforms the data-recursive algorithm in
CursorVisitor back into a non-data recursive one.
This is particularly bad because the data-recursive
algorithm uses more stack space per stack frame,
which can cause us to blow the stack in some cases.

"Fix" this by making the stack that AnnotationTokensWorker
runs in really huge.  The real fix is to modify
AnnotationTokensWorker not to do the explicit
recursive call.

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.

properly determine their source range because they have no context on whether or not they appear in a DeclGroup.

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.

Douglas Gregor 16a2bdd6b0 Introduce a new kind of cursor into libclang, which covers a reference
to an "overloaded" set of declarations. This cursor kind works for
unresolved references to functions/templates (e.g., a call within a

forward declarations.

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.

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.
