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 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*.

Douglas Gregor 8aaca67b0a Robustify PreprocessingRecord slightly, by only creating macro

llvm-svn: 99004
2010-03-19 21:58:23 +00:00
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.

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.

llvm-svn: 98837
2010-03-18 18:04:21 +00:00
Douglas Gregor 065f8d11ca Introduce the notion of a "preprocessing record", which keeps track of
the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.

The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.

Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.

Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

llvm-svn: 96599
2010-02-18 18:47:01 +00:00
Douglas Gregor 33cdd81064 Rework how CIndex handles diagnostics. Rather than using a callback,
we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.

To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.

I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.

Douglas Gregor ac0605e927 Introduce serialization and deserialization of diagnostic information
so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().

The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.

2010-01-25 17:48:13 +00:00
Douglas Gregor 5bce76cd53 Loosen preconditions for clang_getCursorSpelling(), returning an empty
string when given a cursor that does not have a name. Also, don't give
silly names for statements and non-reference expressions.

llvm-svn: 94426
2010-01-25 16:56:17 +00:00
Douglas Gregor 7210063126 Move the type specifier location for elaborated-type-specifiers from
the tag kind (union, struct, class, enum) over to the name of the tag,
if there is a name, since most clients want to point at the name.

Douglas Gregor 9ae8d349e6 Eliminate index-test; all of its tested functionality is now in c-index-test.
llvm-svn: 94211
2010-01-22 20:40:20 +00:00
Douglas Gregor 562c1f9365 Teach CIndex's cursor visitor to restrict its traversal to a specific
region of interest (if provided). Implement clang_getCursor() in terms
of this traversal rather than using the Index library; the unified
cursor visitor is more complete, and will be The Way Forward.

Minor other tweaks needed to make this work:
  - Extend Preprocessor::getLocForEndOfToken() to accept an offset
  from the end, making it easy to move to the last character in the
  token (rather than just past the end of the token).
  - In Lexer::MeasureTokenLength(), the length of whitespace is zero.

llvm-svn: 94200
2010-01-22 19:49:59 +00:00
Douglas Gregor d824f8825b Teach the cursor visitor to walk all of the C and Objective-C
declarations that have enough source information to make such a walk
useful. This includes walking into variable initializers and enum
constants, the types behind typedefs, etc.

llvm-svn: 94124
2010-01-22 00:50:27 +00:00
Douglas Gregor 5e8cf37917 Teach the cursor visitor to walk statements and expressions, including
a few important subkinds. Now we're cookin' with gas!

llvm-svn: 94116
2010-01-21 23:27:09 +00:00
Douglas Gregor d182431968 Teach the cursor visitor to walk into a variety of different TypeLoc
kinds, so that we see referenced types, protocols, classes, etc.

llvm-svn: 94085
2010-01-21 17:29:07 +00:00
Douglas Gregor 93f899509d Introduce type references into the C API, capturing references to
typedefs only (for now).

llvm-svn: 94078
2010-01-21 16:28:34 +00:00
Douglas Gregor 8f40bbee78 Extend the CIndex API with direct support for expressions and
statements, moving some of the more unnatural kinds of references
(VarRef, EnumConstantRef, etc.) over to the expressions. We can now
poke at arbitrary expressions and statements with, e.g.,
clang_getCursor() and get back useful information (e.g., source
ranges).

llvm-svn: 93946
2010-01-19 23:20:36 +00:00
Douglas Gregor accb183371 Introduce the notion of an "unexposed" declaration into the CIndex
API. This is a catch-all for any declaration known to Clang but not
specifically part of the CIndex API. We'll use the same approach with
expressions, statements, references, etc., as needed.

llvm-svn: 93924
2010-01-19 22:07:56 +00:00
Douglas Gregor 6b8232ff82 Eliminate cursor kinds used to express definitions. Instead, provide
CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a
given declaration cursor is also a definition. This eliminates a lot
of duplication in the cursor kinds, and maps more closely to the Clang
ASTs.

This is another API + ABI breaker with no deprecation. Yay, progress.

llvm-svn: 93893
2010-01-19 19:34:47 +00:00
Douglas Gregor ad27e8b777 Introduce clang_getCursorReferenced, to get a cursor pointing at the
entity that a particular cursor references.

llvm-svn: 93830
2010-01-19 01:20:04 +00:00
Douglas Gregor 33c34ac19a Implement clang_getCursorExtent, which provides a source range for the
cursor itself. In particular, for references this returns the source
range of the reference rather than the source range of the thing it
refers to.

Switch c-index-test from clang_getDeclExtent (which will eventually be
deprecated and removed) over to clang_getCursorExtent. The source
ranges we print for references now make sense; fix up the tests
appropriately.

llvm-svn: 93823
2010-01-19 00:34:46 +00:00
Ted Kremenek 473c7a72f1 Replace clang_getDeclUSR() with clang_getCursorUSR(). Also remove printing 'contexts' from c-index-test output; it wasn't helpful and was extremely brittle.
llvm-svn: 93760
2010-01-18 20:23:29 +00:00
Douglas Gregor 46d6614388 Give ObjCClassRef cursors a sane representation, which is encapsulated
in CXCursor.cpp. With this sane representation, fix the class
reference that is part of Objective-C category declarations so that
the cursor's location matches up with the reference, not the class
being referred to.

llvm-svn: 93640
2010-01-16 17:14:40 +00:00
Douglas Gregor 071676f422 Improve location information for Objective-C category declarations. We
previously only had a single location (the @ in @interface); now we
know where the @ is (for the start of the declaration), where the
class name is (that's the normal "location" now for diagnostics), and
where the category name is. Also, eliminated the redundant "end"
location, since ObjCContainerDecl already has better @end information.

The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught
CIndex how to use the new locations.

llvm-svn: 93639
2010-01-16 16:38:58 +00:00
Douglas Gregor ef6eb84da1 Use a sane encoding for CXCursor_ObjCProtocolRef, using the actual
source locations where the protocols were referenced rather than the
location of some random enclosing declaration.

llvm-svn: 93637
2010-01-16 15:44:18 +00:00
Douglas Gregor 6c8959b71b Give CXCursor_ObjCSuperClassRef a sane encoding, which is only known

llvm-svn: 93618
2010-01-16 01:44:12 +00:00
Douglas Gregor 082c3e69eb Add -cursor-at=file:line:column command line option to c-index-test,
to directly check the results of clang_getCursor(). Also, start
migrating some index-test tests over to c-index test [*] and some
grep-using tests over to FileCheck.

llvm-svn: 93537
2010-01-15 19:40:17 +00:00
Douglas Gregor c580c5205f Switch code-completion for ordinary names over to the new(ish)
LookupVisibleDecls, unifying the name lookup mechanisms used by code
completion and typo correction. Aside from the software-engineering
improvements, this makes code-completion see through using directives
and see ivars when performing unqualified name lookup in an
Objective-C instance method.

llvm-svn: 93397
2010-01-14 01:09:38 +00:00
Douglas Gregor 52ce62f069 Improve the sorting of code-completion results. We now always sort by
the "typed" text, first, then take into account
nested-name-specifiers, name hiding, etc. This means that the
resulting sort is actually alphabetical :)

llvm-svn: 93361
2010-01-13 21:54:15 +00:00
Douglas Gregor f193416359 Whenever completing ordinary names for an Objective-C source, also
provide completions for @ keywords. Previously, we only provided
@-completions after an @ was actually typed, which is useful but
probably not the common case.

Also, make sure a few Objective-C 2.0 completions only show up when
Objective-C 2.0 support is enabled (the default).

2010-01-12 06:38:28 +00:00
Ted Kremenek c7c6431860 Change ObjCContainerDecl to contain the entire range for the '@end'
piece of the declaration.  The '@' and the 'end' are separate tokens,
and require two SourceLocations to accurately track.

This change was motivated because ObjCContainerDecl::getSourceRange()
would previously not return the entire range of the declaration (the
'end' would be left off).

Ted Kremenek 00d19ee130 Add 'DeclStmt::DoDestroy()' which doesn't actually recurse over its child expressions (via StmtIterator), as those expressions are owned by the Decls and Types (which are destroyed elsewhere). This fixes a crasher reported in <rdar://problem/7487294>.

2009-12-15 22:01:24 +00:00
Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor d2eb58abac Add support for a chain of stat caches in the FileManager, rather than
only supporting a single stat cache. The immediate benefit of this
change is that we can now generate a PCH/AST file when including
another PCH file; in the future, the chain of stat caches will likely
be useful with multiple levels of PCH files.

Argyrios Kyrtzidis 05ac8276cf Change the semantics for Entity.
Entity can now refer to declarations that are not visible outside the translation unit.
It is a wrapper of a pointer union, it's either a Decl* for declarations that don't
"cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl.

Included is a test case for handling fields across translation units.

Argyrios Kyrtzidis d49e8dd759 Add a C++ indexing test case, where we show the references of overloaded '+' plus signs.
Ok, this is a bit out of place since C++ support is way way off, but it was just too cool to not show it off :-)

Argyrios Kyrtzidis 5641111e3f Make use of the Index library through the index-test tool.

Douglas Gregor c6d5edd2ed Add support for retrieving the Doxygen comment associated with a given
declaration in the AST. 

The new ASTContext::getCommentForDecl function searches for a comment
that is attached to the given declaration, and returns that comment, 
which may be composed of several comment blocks.

Comments are always available in an AST. However, to avoid harming
performance, we don't actually parse the comments. Rather, we keep the
source ranges of all of the comments within a large, sorted vector,
then lazily extract comments via a binary search in that vector only
when needed (which never occurs in a "normal" compile).

Comments are written to a precompiled header/AST file as a blob of
source ranges. That blob is only lazily loaded when one requests a
comment for a declaration (this never occurs in a "normal" compile). 

The indexer testbed now supports comment extraction. When the
-point-at location points to a declaration with a Doxygen-style
comment, the indexer testbed prints the associated comment
block(s). See test/Index/comments.c for an example.

Some notes:
  - We don't actually attempt to parse the comment blocks themselves,
  beyond identifying them as Doxygen comment blocks to associate them
  with a declaration.
  - We won't find comment blocks that aren't adjacent to the
  declaration, because we start our search based on the location of
  the declaration.
  - We don't go through the necessary hops to find, for example,
  whether some redeclaration of a declaration has comments when our
  current declaration does not. Similarly, we don't attempt to
  associate a \param Foo marker in a function body comment with the
  parameter named Foo (although that is certainly possible).
  - Verification of my "no performance impact" claims is still "to be
  done".

Argyrios Kyrtzidis 92772215af Introduce tools/index-test.
This tool will be the test bed for indexing related operations. It basically reads PCH files passed by the command line and performs various operations.

Currently it can accept a file:line:column which resolves to a declaration/statement and displays some information about them.
