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
2010-09-16Implement automatic bracket insertion for Objective-C class messageDouglas Gregor
sends. These are far trickier than instance messages, because we typically have something like NSArray alloc] where it appears to be a declaration of a variable named "alloc" up until we see the ']' (or a ':'), and at that point we can't backtrace. So, we use a combination of syntactic and semantic disambiguation to treat this as a message send only when the type is an Objective-C type and it has the syntax of a class message send (which would otherwise be ill-formed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114057 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-11When parsing default function arguments, do not mark any declarationsDouglas Gregor
used in the default function argument as "used". Instead, when we actually use the default argument, make another pass over the expression to mark any used declarations as "used" at that point. This addresses two kinds of related problems: 1) We were marking some declarations "used" that shouldn't be, because we were marking them too eagerly. 2) We were failing to mark some declarations as "used" when we should, if the first time it was instantiated happened to be an unevaluated context, we wouldn't mark them again at a later point. I've also added a potentially-handy visitor class template EvaluatedExprVisitor, which only visits the potentially-evaluated subexpressions of an expression. I bet this would have been useful for noexcept... Fixes PR5810 and PR8127. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113700 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Eliminate the comma locations from all of the Sema routines that dealDouglas Gregor
with comma-separated lists. We never actually used the comma locations, nor did we store them in the AST, but we did manage to waste time during template instantiation to produce fake locations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113495 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23Introduce a new code-completion point when we're parsing aDouglas Gregor
declarator. Here, we can only see a few things (e.g., cvr-qualifiers, nested name specifiers) and we do not want to provide other non-macro completions. Previously, we would end up in recovery mode and would provide a large number of non-relevant completions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111818 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-06Introduce a new token kind 'cxx_defaultarg_end' to mark the end of C++ ↵Argyrios Kyrtzidis
default arguments that were part of lexed method declarations. This avoid interference with tokens coming after the point where the default arg tokens were 'injected', e.g. for typedef struct Inst { void m(int x=0); } *InstPtr; when parsing '0' the next token would be '*' and things would be messed up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110436 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-11Fix PR7617 by not entering ParseFunctionDefinition whenChris Lattner
a function prototype is followed by a declarator if we aren't parsing a K&R style identifier list. Also, avoid skipping randomly after a declaration if a semicolon is missing.

2010-07-02Move the "current scope" state from the Parser into Action. ThisDouglas Gregor
allows Sema some limited access to the current scope, which we only use in one way: when Sema is performing some kind of declaration that is not directly driven by the parser (e.g., due to template instantiatio or lazy declaration of a member), we can find the Scope associated with a DeclContext, if that DeclContext is still in the process of being parsed. Use this to make the implicit declaration of special member functions in a C++ class more "scope-less", rather than using the NULL Scope hack. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107491 91177308-0d34-0410-b5e6-96231b3b80d8

In a line like: (; the semicolon leaves Parser:ParenCount unbalanced (it's 1 even though we stopped looking for a right paren).

2010-05-30Teach code completion to adjust its completion priorities based on theDouglas Gregor
type that we expect to see at a given point in the grammar, e.g., when initializing a variable, returning a result, or calling a function. We don't prune the candidate set at all, just adjust priorities to favor things that should type-check, using an ultra-simplified type system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@105128 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-25Improve code completion in failure cases in two ways:Douglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104585 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-14Improve error recovery in C/ObjC when the first argument of a functionChris Lattner
