2010-11-17Do not produce "purely informative" code completion results forDouglas Gregor
Objective-C message sends, which have only whitespace in their TypedText chunk. Such results have no purpose. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119569 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Revert the fix for PR8013.Douglas Gregor
That bug concerned the well-formedness of code such as (&ovl)(a, b, c). GCC rejects the code, while EDG accepts it. On further study of the standard, I see no support for EDG's position: in particular, C++ [over.over] does not list this as a context where we can take the address of an overloaded function, C++ [over.call.func] does not reference the address-of operator at any point, and C++ [expr.call] claims that the function argument in a call is either a function lvalue or a pointer-to-function; (&ovl) is neither. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118620 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Handle overload resolution when calling an overloaded function setDouglas Gregor
with, e.g., (&f)(a, b, c). Fixes PR8013. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118508 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Teach code completion not to include out-of-line declarations andDouglas Gregor
definitions in its results. The original declarations will be visible wherever they are declared. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118484 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-08If an instance method messages is sending to an expression of type Class,Douglas Gregor
and we statically can compute a bound on the actual type (e.g., because it's a send to the the magic "class" instance method), code complete as if we were performing a class message send to that class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118443 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-18Fix the translation of the PCC_ForInit code-completion context forDouglas Gregor
C++/C99/Objective-C, so that we properly include types. This fix affects global caching of code-completion results; without caching, the behavior was already correct. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116757 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-18Introduce code completion results for Objective-C methods, both whenDouglas Gregor
declaring methods and when sending messages to them, by bringing all of the selector into TypedCheck chunks in the completion result. This way, we can improve the sorting of these results to account for the full selector name rather than just the first chunk. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116746 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-18When providing code completions of Objective-C method declarationsDouglas Gregor
(after - or +), always traverse superclasses and all categories. The programmer may want to complete a method from *anywhere*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116723 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Eliminate the use of ObjCSuperExpr in code completion.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116436 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Switch c-index-test from clang_codeComplete() over toDouglas Gregor
clang_codeCompleteAt(). This uncovered a few issues with the latter: - ASTUnit wasn't saving/restoring diagnostic state appropriately between reparses and code completions. - "Overload" completions weren't being passed through to the client git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116241 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-08Fix the mapping of vertical-space cursor kinds to produce a newline,Douglas Gregor
rather than a space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116097 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-02When providing a block literal as a code completion for aDouglas Gregor
function/method argument, include the parameter name and always include parentheses (even for zero-parameter blocks). Otherwise, the block literal placeholder '^' can look very weird. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115444 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Synchronize globally-cached code completion results with the resultsDouglas Gregor
provided when the optimization is disabled. In particular, split the completion context CCC_Other into two contexts: CCC_Other, which means that it's an undisclosed context for which any other results are unwelcome, and CCC_Recovery, which is used in recovery cases. Since we're now using the completion context within the completion results builder, make sure that it's always set to something. Fixes <rdar://problem/8470644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114704 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-21Add code completion for C++ constructors wherever we see the class (orDouglas Gregor

2010-09-20Refactor code completion for expressions that occur as arguments inDouglas Gregor
Objective-C message sends. There is no functionality change here; this is prep work for using the parameter types to help guide the expression results when code-completing the argument. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114375 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Code completion has no reason to prefer values over types, especiallyDouglas Gregor
at the statement level or in Objective-C message receivers. Therefore, just give types and declarations the same basic priority, and adjust from there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114374 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Slight refactoring in code-completion results generation, placing theDouglas Gregor
various priority adjustments for preferences (based on selectors, types) in a single function to make extension easier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114370 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Get rid of the lame attempt to prioritize "void" functions atDouglas Gregor
statement context; it really isn't helpful in practice (remember printf!) and we'll be doing other adjustments for statements very soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114358 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-20Tweak priorities for some types and macros:Douglas Gregor
- In Objective-C, we prefer BOOL to bool for historic reasons; slightly penalize "bool". - Treat Nil macro as a NULL pointer constant. - Treat YES, NO, true, and false macros as constants. - Treat the bool macro as a type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114356 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-18Continue parsing more postfix expressions, even after semanticDouglas Gregor
errors. Improves code completion in yet another case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114255 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16Don't add two code-completion results for the same selector; itDouglas Gregor
doesn't add any value. Instead, we'll just take the first method with that selector that we find and create a completion for it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114082 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16When collecting Objective-C methods for message send completions, beDouglas Gregor
sure to visit the protocols of protocols. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114079 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-16Implement code completion for Objective-C class message sends that areDouglas Gregor
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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114078 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-15Improve code completion for Objective-C message sends when the openingDouglas Gregor
'[' 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113976 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-14Introduce a new code-completion context for a parenthesizedDouglas Gregor
expression, e.g., after the '(' that could also be a type cast. Here, we provide types as code-completion results in C/Objective-C (C++ already had them), although we wouldn't in a normal expression context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113904 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Teach libclang to walk the base and member initializers of aDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113545 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-01Split ObjCInterfaceDecl::ReferencedProtocols into two lists: ↵Ted Kremenek
ReferencedProtocols and AllReferencedProtocols. ReferencedProtocols (and thus protocol_begin(), protocol_end()) now only contains the list of protocols that were directly referenced in an @interface declaration. 'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced in both the @interface and class extensions. The latter is needed for semantic analysis/codegen, while the former is needed to maintain the lexical information of the original source. Fixes <rdar://problem/8380046>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112691 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-29When providing a code completion for an Objective-C message send, dropDouglas Gregor
the parameter names from the completions, e.g., provide withString:(NSString *) instead of withString:(NSString *)string since the parameter name is, by convention, redundant with the selector piece that precedes it and the completions can get unnecessarily long. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112456 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-29Improve code completion for initializer lists in constructors. InsteadDouglas Gregor
of prioritizing just by initialization order, we bump the priority of just the *next* initializer in the list, and leave everything else at the normal priority. That way, if one intentionally skips the initialization of a base or member (to get default initialization), we'll still get ordered completion for the rest. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112454 91177308-0d34-0410-b5e6-96231b3b80d8
