2010-09-15Implement bracket insertion for Objective-C instance message sends asDouglas Gregor
part of parser recovery. For example, given: a method1:arg]; we detect after parsing the expression "a" that we have the start of a message send expression. We pretend we've seen a '[' prior to the a, then parse the remainder as a message send. We'll then give a diagnostic+fix-it such as: fixit-objc-message.m:17:3: error: missing '[' at start of message send expression a method1:arg]; ^ [ The algorithm here is very simple, and always assumes that the open bracket goes at the beginning of the message send. It also only works for non-super instance message sends at this time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113968 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Modify the pragma handlers to accept and use StringRefs instead of ↵Argyrios Kyrtzidis
IdentifierInfos. When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded). We can avoid this if we just use StringRefs for the pragmas. As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108237 91177308-0d34-0410-b5e6-96231b3b80d8

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
2010-06-17Make sure parens/braces/brackets are correctly balanced.Argyrios Kyrtzidis
In a line like: (; the semicolon leaves Parser:ParenCount unbalanced (it's 1 even though we stopped looking for a right paren). This may affect later parsing and result in bad recovery for parsing errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106213 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-16Fix the recently-added warning about 'typename' and 'template'Douglas Gregor
disambiguation keywords outside of templates in C++98/03. Previously, the warning would fire when the associated nested-name-specifier was not dependent, but that was a misreading of the C++98/03 standard: now, we complain only when we're outside of any template. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106161 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
2010-05-21Improve parser recovery when we encounter a dependent template nameDouglas Gregor
that is missing the 'template' keyword, e.g., t->getAs<T>() where getAs is a member of an unknown specialization. C++ requires that we treat "getAs" as a value, but that would fail to parse since T is the name of a type. We would then fail at the '>', since a type cannot be followed by a '>'. This is a very common error for C++ programmers to make, especially since GCC occasionally allows it when it shouldn't (as does Visual C++). So, when we are in this case, we use tentative parsing to see if the tokens starting at "<" can only be parsed as a template argument list. If so, we produce a diagnostic with a fix-it that states that the 'template' keyword is needed: test/SemaTemplate/dependent-template-recover.cpp:5:8: error: 'template' keyword is required to treat 'getAs' as a dependent template name t->getAs<T>(); ^ template This is just a start of this patch; I'd like to apply the same approach to everywhere that a template-id with dependent template name can be parsed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104406 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-10Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall
when they're instantiated. Merge the note into the -Wreorder warning; it doesn't really contribute much, and it was splitting a thought across diagnostics anyway. Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100922 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01Keep an explicit stack of function and block scopes, each element ofDouglas Gregor
which has the label map, switch statement stack, etc. Previously, we had a single set of maps in Sema (for the function) along with a stack of block scopes. However, this lead to funky behavior with nested functions, e.g., in the member functions of local classes. The explicit-stack approach is far cleaner, and we retain a 1-element cache so that we're not malloc/free'ing every time we enter a function. Fixes PR6382. Also, tweaked the unused-variable warning suppression logic to look at errors within a given Scope rather than within a given function. The prior code wasn't looking at the right number-of-errors count when dealing with blocks, since the block's count would be deallocated before we got to ActOnPopScope. This approach works with nested blocks/functions, and gives tighter error recovery. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97518 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11Clean up ownership of 'AttributeList' objects in Parser. ApparentlyTed Kremenek
we would just leak them all over the place, with no clear ownership of these objects at all. AttributeList objects would get leaked on both error and non-error paths. Note: I introduced the usage of llvm::OwningPtr<AttributeList> to manage these objects, which is particularly useful for methods with multiple return sites. In at least one method I used them even when they weren't strictly necessary because it clarified the ownership semantics and made the code easier to read. Should the excessive 'take()' and 'reset()' calls become a performance issue we can always re-evaluate. Note+1: I believe I have not introduced any double-frees, but it would be nice for someone to review this.
