Douglas Gregor 6da3db4af3 Improve code completion in failure cases in two ways:
1) Suppress diagnostics as soon as we form the code-completion
  token, so we don't get any error/warning spew from the early
  end-of-file.
  2) If we consume a code-completion token when we weren't expecting
  one, go into a code-completion recovery path that produces the best
  results it can based on the context that the parser is in.

Ted Kremenek 49be9e0819 Teach CursorVisitor about duplicate ObjCPropertyDecls that can arise because of a current
design limitation in how we handle Objective-C class extensions.  This was causing the CursorVisitor
to essentially visit an @property twice (once in the @interface, the other in the class extension).
Fixes <rdar://problem/7410145>.

Ted Kremenek 6bca984b54 Add CXType and an initial set of supporting functions to libclang. This exposes details of
Clang's representation of the C type system to clients.  It is nowhere near complete, and will
be expanded on demand.

Ted Kremenek 12e0f2937e Specially handle CaseStmts in CursorVisitor because they can be nested and walking them
can blow out the stack.

Daniel Dunbar 6399208c14 Revert "Move macro definitions for IBOutlet and IBAction into the source

Ted Kremenek 847941b1f4 Correctly check if a cursor is a declaration before returning its location/range in clang_getCursorLocation()/clang_getCursorExtent(). This fixes a horrible bug reported in
<rdar://problem/7961995> and <rdar://problem/7967123> where declarations with attributes
would get grossly annotated with the wrong tokens because the attribute would be interpreted
as if it was a Decl*.

Ted Kremenek 37c220c8ed Extend C++ usrs to include type mangling for tag decl arguments, indicating whether a method

Ted Kremenek 5b0773e201 Workaround a really serious caching bug in SourceManager::isBeforeInTranslationUnit() where the
method will sometimes return different results for the same input SourceLocations.  I haven't
unraveled this method completely yet, so this truly is a workaround until a better fix comes
along.

Ted Kremenek 680fe51e2c Rework clang_annotateTokens() to annotate tokens with information that more closely matches
clang_getCursor().  Tokens are now annotated with the cursor (for the matching AST element)
that most closely encompasses that token.

Ted Kremenek acc59c3ec9 Workaround: Don't add ObjCMethodDecls to the vector of TopLevelDecls since they don't go in
the DeclContext for the translation unit.  This is to workaround a fundamental issue in how
ObjC decls (within an @implementation) are parsed before the ObjCContainerDecl is available.

Ted Kremenek 7afa85b8fa Rework USR generation for symbols with no linkage. Many of the USRs are now shortened,
and we now include the file name that declares the symbol with no linkage in the USR.
USRs for such symbols are generated only in restructed cases, e.g., anonymous enum declarations,
typedefs, etc.

Douglas Gregor 636a61e0d2 Implement code completion for Objective-C method declarations and
definitions, e.g., after 

  -

or

  - (id)

we'll find all of the "likely" instance methods that one would want to
declare or define at this point. In the latter case, we only produce
results whose return types match "id".

Douglas Gregor d720daf8bc Make code-completion for Objective-C message sends to "id" work in the
presence of precompiled headers by forcibly loading all of the
methods we know about from the PCH file before constructing our
code-completion list.

2010-04-06 17:30:22 +00:00
Douglas Gregor 6285f754fa Implement support for code completion of an Objective-C message send to
"id" or an expression of type "id". In these cases, we produce a list
of all of the (class or instance) methods, respectively, that we know about.

Note that this implementation does not yet work well with precompiled
headers; that's coming soon.

Douglas Gregor 8aaca67b0a Robustify PreprocessingRecord slightly, by only creating macro
instantiations when we have the corresponding macro definition and by
removing macro definition information from our table when the macro is
undefined.

Douglas Gregor aae9224e49 Implement serialization and lazy deserialization of the preprocessing
record (which includes all macro instantiations and definitions). As
with all lay deserialization, this introduces a new external source
(here, an external preprocessing record source) that loads all of the
preprocessed entities prior to iterating over the entities.

The preprocessing record is an optional part of the precompiled header
that is disabled by default (enabled with
-detailed-preprocessing-record). When the preprocessor given to the
PCH writer has a preprocessing record, that record is written into the
PCH file. When the PCH reader is given a PCH file that contains a
preprocessing record, it will be lazily loaded (which, effectively,
implicitly adds -detailed-preprocessing-record). This is the first
case where we have sections of the precompiled header that are
added/removed based on a compilation flag, which is
unfortunate. However, this data consumes ~550k in the PCH file for
Cocoa.h (out of ~9.9MB), and there is a non-trivial cost to gathering
this detailed preprocessing information, so it's too expensive to turn
on by default. In the future, we should investigate a better encoding
of this information.

2010-03-19 21:51:54 +00:00
Douglas Gregor 51c2351d30 Fix a longstanding (but previously unknown) bug in the lazy
deserialization of precompiled headers, where the deserialization of
the source location entry for a buffer (e.g., macro instantiation
scratch space) would overwrite a one-element FileID cache in the
source manager. When tickled at the wrong time, we would return the
wrong decomposed source location and eventually cause c-index-test to
crash.

Found by dumb luck. It's amazing this hasn't shown up before.
