2010-11-17 23:24:11 +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).

Douglas Gregor 229bebdeb5 ntroduce clang_getSpellingLocation() into libclang, to provide the
location where we're spelling a token even within a
macro. clang_getInstantiationLocation() tells where we instantiated
the macro.

I'm still not thrilled with the CXSourceLocation/CXSourceRange APIs,
since they gloss over macro-instantiation information.

Take 2: this time, adjusted tests appropriately and used a "simple"
approach to the spelling location.

David Chisnall b2aa0ef310 Added cursor visitor that takes a block as an argument. Tested compiling
libclang with both clang -fblocks and gcc (no blocks support).  Only exposed in
the header to compilers that do have blocks support.

Douglas Gregor 796d76a663 Extend the preprocessing record and libclang with support for
inclusion directives, keeping track of every #include, #import,
etc. in the translation unit. We keep track of the source location and
kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

llvm-svn: 116952
2010-10-20 22:00:55 +00:00
David Chisnall 2e16ac52e1 Add clang_getLocationForOffset() to libclang, for gives a source location from a character index into a file.

Douglas Gregor 6a95802893 Eliminate clang_codeComplete(). libclang clients should be using the
faster, in-process, more-configurable clang_codeCompleteAt(). 

llvm-svn: 116245
2010-10-11 21:51:20 +00:00
Douglas Gregor 7845f1e80e Eliminate clang_setUseExternalASTGeneration() from libclang. Between
improvements to the compiler and the introduction of crash recovery,
it no longer makes sense to allow this mode. Moreover, this eliminates
one use of the "clang" executable from within libclang; we'd like them
all to go away.

llvm-svn: 116207
2010-10-11 16:52:23 +00:00
Douglas Gregor 97c7571ef3 Introduce a new libclang function, clang_getCursorDisplayName(), which
produces a simple "display" name that captures the
arguments/parameters for a function, function template, class
template, or class template specialization.

llvm-svn: 115428
2010-10-02 22:49:11 +00:00
Douglas Gregor 99a26afd49 Extend libclang with an API that determines, given a C++ virtual
member function or an Objective-C method, which other member
functions/methods it overrides.

llvm-svn: 115338
2010-10-01 20:25:15 +00:00
Douglas Gregor 0576ce730a Implement libclang API functions for retrieving the lexical and
semantic parents of the given cursor.

llvm-svn: 114587
2010-09-22 21:22:29 +00:00
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
template), using declarations, and Objective-C class and protocol
forward declarations.

llvm-svn: 113805
2010-09-13 22:52:57 +00:00
Douglas Gregor a93ab66331 Add libclang support for label statements, gotos, and taking the
address of a label (GNU extension).

llvm-svn: 113564
2010-09-10 00:22:18 +00:00
Douglas Gregor f3af311382 Teach libclang to walk the base and member initializers of a
constructor, in source order. Also introduces a new reference kind for
class members, which is used here (for member initializers) and will
also be used for designated initializers and offsetof.

llvm-svn: 113545
2010-09-09 21:42:20 +00:00
Douglas Gregor d3f48bd3be Introduce a new libclang function,
clang_getSpecializedCursorTemplate(), which determines the template
(or member thereof) that the given cursor specializes or from which it
was instantiated. This routine can be used to establish a link between
templates and their instantiations/specializations.

llvm-svn: 112780
2010-09-02 00:07:54 +00:00
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.

llvm-svn: 112730
2010-09-01 19:52:22 +00:00
Douglas Gregor 57879faf91 Make it clear that libclang does not modify the command-line arguments
it is given.

llvm-svn: 112717
2010-09-01 16:43:19 +00:00
Douglas Gregor 01a430134f Implement libclang support for using directives (cursor + visitation +
suppressing USRs). Also, fix up the source location information for
using directives so that the declaration location refers to the
namespace name.

llvm-svn: 112693
2010-09-01 03:07:18 +00:00
Douglas Gregor a89314e396 Add libclang support for namespace aliases (visitation + USRs) along
with a new cursor kind for a reference to a namespace. 

There's still some oddities in the source location information for
NamespaceAliasDecl that I'll address with a separate commit, so the
source locations displayed in the load-namespaces.cpp test will
change.

llvm-svn: 112676
2010-08-31 23:48:11 +00:00
Douglas Gregor f11309e194 Add a new libclang function clang_getTemplateCursorKind(), which
determines the kind of declaration that would be generated if the
given template were instantiated. This allows a client to distinguish
among class/struct/union templates and function/member function/static
member function templates.

Also, teach clang_CXXMethod_isStatic() about function templates.

llvm-svn: 112655
2010-08-31 22:12:17 +00:00
Douglas Gregor a23e8f7a0f Extend libclang with a new cursor kind that indicates a reference to a
template. Such cursors occur, for example, in template specialization
types such as vector<int>. Note that we do not handle the
super-interesting case where the template name is unresolved, e.g.,
within a template.

llvm-svn: 112636
2010-08-31 20:37:03 +00:00
Douglas Gregor f96abb293a Add libclang support for class template partial specializations,
including a cursor kind, visitation, and USRs.

llvm-svn: 112629
2010-08-31 19:31:58 +00:00
Douglas Gregor 1fbaeb196b Add a libclang cursor kind, visitation support and USR support for C++
class templates. 

llvm-svn: 112627
2010-08-31 19:02:00 +00:00
Douglas Gregor 713602bb09 Implement basic support for indexing function templates in
libclang. This includes:
  - Cursor kind for function templates, with visitation logic
  - Cursor kinds for template parameters, with visitation logic
  - Visitation logic for template specialization types, qualified type
  locations
  - USR generation for function templates, template specialization
  types, template parameter types.

Also happens to fix PR7804, which I tripped across while testing.

llvm-svn: 112604
2010-08-31 17:01:39 +00:00
Douglas Gregor 12bca22e91 libclang indexing support for C++ constructors, destructors, and
conversion functions. This introduces new cursor kinds for these three
C++ entities, and reworks visitation of function declarations so that
we get type-source information for the names.

llvm-svn: 112600
2010-08-31 14:41:23 +00:00
Ted Kremenek ae9e221513 Implement CXCursor support for walking C++ base specifiers. This includes adding the API hooks clang_isVirtualBase() and clang_getCXXAccessSpecifier() to query properties of the base specifier.

Douglas Gregor f757a12dfc Introduce new libclang API functions that determine the availability
of a cursor or code-completion result, e.g., whether that result
refers to an unavailable, deleted, or deprecated declaration.

llvm-svn: 111858

llvm-svn: 111016
2010-08-13 15:35:05 +00:00
Douglas Gregor e938668003 Implement clang_saveTranslationUnit(), which saves a translation unit
into a PCH/AST file.

llvm-svn: 111006
2010-08-13 05:36:37 +00:00
Douglas Gregor de05118c84 Add a (currently unused) "options" parameter to
clang_reparseTranslationUnit(), along with a function to retrieve the
default recommended reparsing options for a translation unit.

Also, add the CXTranslationUnit_CacheCompletionResults flag, which is
also currently unused.

llvm-svn: 110811
2010-08-11 15:58:42 +00:00
Douglas Gregor 4a47bca47d Instead of having a specific CXTranslationUnit_* option flag for
"editing" mode, introduce a separate function
clang_defaultEditingTranslationUnitOptions() that retrieves the set of
options. No functionality change.

llvm-svn: 110613

llvm-svn: 110596
2010-08-09 20:45:32 +00:00
Douglas Gregor b68bc59a2d Give clang_codeCompleteAt() an "options" parameter, and add a new
flags enumeration + default-generating function that allows
code-completion to be customized via the libclang API.

Plus, turn on spell-checking when performing code completion.

llvm-svn: 110319
2010-08-05 09:09:23 +00:00
Douglas Gregor 8e984da800 Add code-completion support directly to ASTUnit, which performs code
completion within the translation unit using the same command-line
arguments for parsing the translation unit. Eventually, we'll reuse
the precompiled preamble to improve code-completion performance, and
this also gives us a place to cache results.

Expose this function via the new libclang function
clang_codeCompleteAt(), which performs the code completion within a
CXTranslationUnit. The completion occurs in-process
(clang_codeCompletion() runs code completion out-of-process).

2010-07-23 00:33:23 +00:00
Douglas Gregor 99d2cf4838 Introduce a new C API function, clang_parseTranslationUnit(), which
will eventually replace
clang_createTranslationUnitFromSourceFile(). The only addition in
clang_parseTranslationUnit() is a set of flags that can control how
the translation unit is loaded. More interesting flags will be coming.

llvm-svn: 109027
2010-07-21 18:52:53 +00:00
Douglas Gregor aa21cc401b Introduce a new libclang API, clang_reparseTranslationUnit(), which

convenience function, but we hope to use it for performance
optimizations.

should probably be factored out of this routine, but we're not there
yet.

Douglas Gregor 89a56c561f When given unsaved files in clang_createTranslationUnitFromSourceFile,
copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

Douglas Gregor d770f73fac Rework the CIndex API for displaying diagnostics. Instead of printing
the diagnostics to a FILE*, return a CXString containing the formatted
diagnostic.

Douglas Gregor 1e21cc7d19 Re-apply my diagnostics-capture patch for CIndex, with some tweaks to
try to address the msvc failures.

Douglas Gregor 9773e3d077 Revert my CIndex diagnostic changes (r96603, 96606, 96607), which were
breaking the msvc9 builder for unknown reasons.

Douglas Gregor 81d53769b5 Introduce debugging/testing hook clang_enableStackTraces() into
CIndex, so that c-index-test to use it to call
lvm::sys::PrintStackTraceOnErrorSignal().

Douglas Gregor 707cf72cb8 Resurrect the displayDiagnostics parameter to clang_createIndex(), and
display captured diagnostics when we can't return an invalid
CXTranslationUnit.

Douglas Gregor 06dcf0375b Introduce CIndex API functions for displaying a diagnostic, with some
knobs to control formatting. Eventually, I'd like to merge the
implementation of this code with the TextDiagnosticPrinter, so that
it's easy for CIndex clients to produce beautiful diagnostics like the
clang compiler does.

Use this new function to display diagnostics within c-index-test.

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.
