2010-04-12Improve source-location information for C++ conversion functions, byDouglas Gregor
copying the type location information from the conversion-type-id into the type location information for the function type. Do something similar for constructors and destructors, by giving their "void" return type source-location information. In all of these cases, we previously left this type-source information uninitialized, which led to various unfortunate crashes. We still aren't tracking good source-location information for the actual names. That's PR6357. John, please check my sanity on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101088 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12When creating the implicitly-declared special member functions, beDouglas Gregor
sure to introduce them into the current Scope (when we have one) in addition to the DeclContext for the class, so that they can be found by name lookup for inline members of the class. Fixes PR6570. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101047 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Be sure to instantiate the parameters of a function, even when theDouglas Gregor
function's type is (strictly speaking) non-dependent. This ensures that, e.g., default function arguments get instantiated properly. And, since I couldn't resist, collapse the two implementations of function-parameter instantiation into calls to a single, new function (Sema::SubstParmVarDecl), since the two had nearly identical code (and each had bugs the other didn't!). More importantly, factored out the semantic analysis of a parameter declaration into Sema::CheckParameter, which is called both by Sema::ActOnParamDeclarator (when parameters are parsed) and when a parameter is instantiated. Previously, we were missing some Objective-C and address-space checks on instantiated function parameters. Fixes PR6733. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101029 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-11fix PR6811 by not parsing 'super' as a magic expression inChris Lattner
LookupInObjCMethod. Doing so allows all sorts of invalid code to slip through to codegen. This patch does not change the AST representation of super, though that would now be a natural thing to do since it can only be in the receiver position and in the base of a ObjCPropertyRefExpr. There are still several ugly areas handling super in the parser, but this is definitely a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100959 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-11actually the interface grossness in the previous patch was due toChris Lattner
typo correction. However, now that the code has been factored out of LookupMemberExpr, it can recurse to itself instead of to LookupMemberExpr! Remove grossness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100958 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-11factor the code that handles "expr.field" when expr is aChris Lattner

2010-04-06Implement the protected access restriction ([class.protected]), which requiresJohn McCall
that protected members be used on objects of types which derive from the naming class of the lookup. My first N attempts at this were poorly-founded, largely because the standard is very badly worded here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100562 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-01Overhaul checking of non-type template arguments that should refer toDouglas Gregor
an object or function. Our previous checking was too lax, and ended up allowing missing or extraneous address-of operators, among other evils. The new checking provides better diagnostics and adheres more closely to the standard.

2010-03-30Propagate the "found declaration" (i.e. the using declaration instead ofJohn McCall
the underlying/instantiated decl) through a lot of API, including "intermediate" MemberExprs required for (e.g.) template instantiation. This is necessary because of the access semantics of member accesses to using declarations: only the base class *containing the using decl* need be accessible from the naming class. This allows us to complete an access-controlled selfhost, if there are no recent regressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99936 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Optimize PartialDiagnostic's memory-allocation behavior by placing aDouglas Gregor
cache of PartialDiagnostic::Storage objects into an allocator within the ASTContext. This eliminates a significant amount of malloc traffic, for a 10% performance improvement in -fsyntax-only wall-clock time with 403.gcc's combine.c. Also, eliminate the RequireNonAbstractType hack I put in earlier, which was but a symptom of this larger problem.

2010-03-28After performing template argument deduction for a function template,Douglas Gregor
check deduced non-type template arguments and template template arguments against the template parameters for which they were deduced, performing conversions as appropriate so that deduced template arguments get the same treatment as explicitly-specified template arguments. This is the bulk of PR6723. Also keep track of whether deduction of a non-type template argument came from an array bound (vs. anywhere else). With this information, we enforce C++ [temp.deduct.type]p17, which requires exact type matches when deduction deduces a non-type template argument from something that is not an array bound. Finally, when in a SFINAE context, translate the "zero sized arrays are an extension" extension diagnostic into a hard error (for better standard conformance), which was a minor part of PR6723. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99734 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Teach the diagnostic engine to provide more detailed information aboutDouglas Gregor
how to handle a diagnostic during template argument deduction, which may be "substitution failure", "suppress", or "report". This keeps us from, e.g., emitting warnings while performing template argument deduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99560 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Improve our handling of local instantiation scopes in two related ways:Douglas Gregor
- When substituting template arguments as part of template argument deduction, introduce a new local instantiation scope. - When substituting into a function prototype type, introduce a new "temporary" local instantiation scope that merges with its outer scope but also keeps track of any additions it makes, removing them when we exit that scope. Fixes PR6700, where we were getting too much mixing of local instantiation scopes due to template argument deduction that substituted results into function types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99509 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24When a declaration of a function is missing an exception specificationDouglas Gregor
that was present in a prior declaration, emit a warning rather than a hard error (which we did before, and still do with mismatched exception specifications). Moreover, provide a fix-it hint with the throw() clause that should be added, e.g., t.C:10:7: warning: 'operator new' is missing exception specification 'throw(std::bad_alloc)' void *operator new(unsigned long sz) ^ throw(std::bad_alloc) As part of this, disable the warning when we're missing an exception specification on operator new, operator new[], operator delete, or operator delete[] when exceptions are turned off (-fno-exceptions). Fixes PR5957. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99388 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Implement a framework for the delay of arbitrary diagnostics withinJohn McCall
templates. So delay access-control diagnostics when (for example) the target of a friend declaration is a specific specialization of a template. I was surprised to find that this was required for an access-controlled selfhost. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99383 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-22-Wshadow should only warn about parameter declarations when we'reJohn McCall
entering a function or block definition, not on every single declaration. Unfortunately we don't have previous-lookup results around when it's time to make this decision, so we have to redo the lookup. The alternative is to use delayed diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99172 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-20Refactor CFG-based warnings in Sema to be run by a worked object called ↵Ted Kremenek
AnalysisBasedWarnings. This object controls when the warnings are executed, allowing the client code in Sema to selectively disable warnings as needed. Centralizing the logic for analysis-based warnings allows us to optimize when and how they are run. Along the way, remove the redundant logic for the 'check fall-through' warning for blocks; now the same logic is used for both blocks and functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99085 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19Remove the capture, serialization, and deserialization of commentDouglas Gregor

2010-03-19Remember the "found declaration" for an overload candidate, which is theJohn McCall
entity (if applicable) which was actually looked up. If a candidate was found via a using declaration, this is the UsingShadowDecl; otherwise, if the candidate is template specialization, this is the template; otherwise, this is the function. The point of this exercise is that "found declarations" are the entities we do access control for, not their underlying declarations. Broadly speaking, this patch fixes access control for using declarations. There is a *lot* of redundant code calling into the overload-resolution APIs; we really ought to clean that up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98945 91177308-0d34-0410-b5e6-96231b3b80d8

I found a way to reduce some of the redundancy between TreeTransform's "standard" FunctionProtoType transformation and TemplateInstantiator's override, and I killed off the old SubstFunctionType by adding type source info for the last cases where we were creating FunctionDecls without TSI (at least that get passed through template instantiation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98252 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-03Implement disambiguation of base class members via aDouglas Gregor
nested-name-specifier. For example, this allows member access in diamond-shaped hierarchies like: struct Base { void Foo(); int Member; }; struct D1 : public Base {}; struct D2 : public Base {}; struct Derived : public D1, public D2 { } void Test(Derived d) { d.Member = 17; // error: ambiguous cast from Derived to Base d.D1::Member = 17; // error: okay, modify D1's Base's Member } Fixes PR5820 and <rdar://problem/7535045>. Also, eliminate some redundancy between Sema::PerformObjectMemberConversion() and Sema::PerformObjectArgumentInitialization() -- the latter now calls the former. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97674 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
