of a binary expression, continue on and parse the right-hand side of
the binary expression anyway, but don't call the semantic actions to
type-check. Previously, we would see the error and then, effectively,
skip tokens until the end of the statement.
The result should be more useful recovery, both in the normal case
(we'll actually see errors beyond the first one in a statement), but
it also helps code completion do a much better job, because we do
"real" code completion on the right-hand side of an invalid binary
expression rather than completing with the recovery completion. For
example, given
x = p->y
if there is no variable named "x", we can still complete after the p->
as a member expression. Along the recovery path, we would have
completed after the "->" as if we were in an expression context, which
is mostly useless.
llvm-svn: 114225
missing the opening bracket '[', e.g.,
NSArray <CC>
at function scope. Previously, we would only give trivial completions
(const, volatile, etc.), because we're in a "declaration name"
scope. Now, we also provide completions for class methods of NSArray,
e.g.,
alloc
Note that we already had support for this after the first argument,
e.g.,
NSArray method:x <CC>
would get code completion for class methods of NSArray whose selector
starts with "method:". This was already present because we recover
as if NSArray method:x were a class message send missing the opening
bracket (which was committed in r114057).
llvm-svn: 114078
narrow, almost useless case where we're inside a parenthesized

The solution to the general case still eludes me.
llvm-svn: 114039
'[' is missing. Prior commits improving recovery also improved code
completion beyond the first selector, e.g., at or after the "to" in
calculator add:x to:y
but not after "calculator". We now provide the same completions for
calculator <CC>
that we would for
[calculator <CC>
if "calculator" is an expression whose type is something that can
receive Objective-C messages.
This code completion works for instance and super message sends, but not
class message sends.

preambles end up leaving the precompiled preambles around. This is by

it's unfortunate for testing, so introduce a hook that allows these

delete them after testing.

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.

an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced

needed to maintain the lexical information of the original source.

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.

llvm-svn: 112456
of prioritizing just by initialization order, we bump the priority of
just the *next* initializer in the list, and leave everything else at

we'll still get ordered completion for the rest.

nested-name-specifiers. Also includes fixes to the generation of
nested-name-specifier result in the non-cached case; we were producing

the usage type of each declaration result, then compare those types to
the preferred type of the completion. This provides parity in the
priority calculation between the code-completion results produced
directly from Sema and those cached by ASTUnit.
For the standard Cocoa.h (+ others) example, there's a penalty of 3-4
hundredeths of a second when caching the global results (for ~31,000
results), because we need an ASTContext-agnostic representation of
types for the comparison, and therefore we use... strings. Eventually,
we'd like to implement a more efficient ASTContext-agnostic encoding
of types.
llvm-svn: 111165
type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.
This gets us one step closer to parity of the cached completion
results with the non-cached completion results.
llvm-svn: 111139
declarations (in addition to macros). Each kind of declaration maps to
a certain set of completion contexts, and the ASTUnit completion logic
introduces the completion strings for those declarations if the actual
code-completion occurs in one of the contexts where it matters.
There are a few new code-completion-context kinds. Without these,
certain completions (e.g., after "using namespace") would need to
suppress all global completions, which would be unfortunate.
Note that we don't get the priorities right for global completions,
because we don't have enough type information. We'll need a way to
compare types in an ASTContext-agnostic way before this can be
implemented.
llvm-svn: 111093
when the CXTranslationUnit_CacheCompletionResults option is given to
clang_parseTranslationUnit(). Essentially, we compute code-completion
results for macro definitions after we have parsed the file, then
store an ASTContext-agnostic version of those results (completion
string, cursor kind, priority, and active contexts) in the
ASTUnit. When performing code completion in that ASTUnit, we splice
the macro definition results into the results provided by the actual
code-completion (which has had macros turned off) before libclang gets
those results. We use completion context information to only splice in
those results that make sense for that context.
With a completion involving all of the macros from Cocoa.h and a few other
system libraries (totally ~8500 macro definitions) living in a
precompiled header, we get about a 9% performance improvement from
code completion, since we no longer have to deserialize all of the
macro definitions from the precompiled header.
Note that macro definitions are merely the canary; the cache is
designed to also support other top-level declarations, which should be
a bigger performance win. That optimization will be next.
Note also that there is no mechanism for determining when to throw
away the cache and recompute its contents.

- Eagerly create ObjCInterfaceTypes for declarations.
- The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another.
- Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated.

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.

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.
llvm-svn: 99002
deserialization of precompiled headers, where the deserialization 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.

Use this new function to display diagnostics within c-index-test.
llvm-svn: 96603
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.

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.

Minor other tweaks needed to make this work:

CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a

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

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.

'end' would be left off).

- 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).

specializations and class template partial specializations (they're
never named directly). Also, member access expressions only refer to
value declarations (fields, functions, enumerators, etc.) and
Objective-C property declarations; filter out everything else.

- We need to be more careful in the rest of CIndex if we are to handle
possibly-invalid ASTs, and don't have much experience with this yet.

from a source file.
- This allows CIndex to avoid iterating over all the top-level decls when using
a PCH, which means we deserialize far fewer decls.

quite slow and doesn't really stress the APIs people should really use.
- I'm not even sure if this mode is still useful given the other scanning mode;

provide completion results before each keyword argument, e.g.,
[foo Method:arg WithArg1:arg1 WithArg2:arg2]
We now complete before "WithArg1" and before "WithArg2", in addition
to completing before "Method".

declaration by providing patterns for "getter = <method>" and "setter
= <method>". As part of this, invented a new "pattern" result kind
that is merely a semantic string. The "pattern" result kind should
help with other kinds of code templates.

code to find and add Objective-C methods (starting at an
ObjCContainerDecl) into a single, static function. Also, make sure
that we search into the implementations of classes and categories to
find even more methods.

header or not via a new "PCHLevel" field in Decl. We currently use
this information to help CIndex filter out declarations that came from
a precompiled header (rather than from an AST file). Further down the
road, it can be used to help implement multi-level precompiled
headers.

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.

Fix clang_getCursorDecl to do the right thing for expr refs
Fixup test file to accommodate new output (which includes the line/column for the referenced decl)

such initializations properly convert constructor arguments and fill
in default arguments where necessary. This also makes the ownership
model more clear.

Doug, please look at decltype-crash and instantiate-function-1.mm, I'm not sure
if they are actually testing the right thing / anything.

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.

'index-test' is now able to provide additional info for a Decl, through multiple AST files:
-Find declarations
-Find definitions
-Find references

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".

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.
