2010-03-31Extend DependentNameType with a keyword enum that specifies whetherDouglas Gregor
this was parsed as a typename-specifier, elaborated-type-specifier (including the kind), or just a dependent qualified type name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100039 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31Rename CodeModificationHint to FixItHint, since we've been using theDouglas Gregor
term "fix-it" everywhere and even *I* get tired of long names sometimes. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100008 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30the big refactoring bits of PR3782.Rafael Espindola
This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99920 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27Implement method friends in class templates and fix a few related problems.John McCall

2010-03-25When finishing a function definition, leave the function definition *after*John McCall
doing all the cleanup tasks and checks. This gives us the proper context for checking access to base and member destructors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99559 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Handle simple friend-class decls in class templates better by ensuring thatJohn McCall
we look for shadow friend decls in the appropriate scope before injecting a new declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99552 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-24Silently drop dependent friend function template specializations,Douglas Gregor
since we have absolutely no way to match them when they are declared nor do we have a way to represent these parsed-but-not-checked friend declarations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99407 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-24Correct that last fixit: if the user wroteJohn McCall
template <> friend void foo(int); we need to change it to friend void foo<>(int); or else the user won't get the template specialization they obviously want. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99390 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-23When recovering from a qualified typedef name, don't clear out theDouglas Gregor
DeclContext because we don't want a NULL DeclContext. Instead, use the current context. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99281 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-23Only perform CFG-based warnings on 'static inline' functions thatTed Kremenek
are called (transitively) by regular functions/blocks within a translation untion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99233 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
2010-03-21Fix PR6618.Rafael Espindola
If a struct has an invalid field, mark it as invalid. Also avoid producing errors about incomplete types that are invalid. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99150 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

2010-03-18Redeclaration lookups for parameter names should be flagged as redeclaration ↵John McCall
lookups so they don't trigger diagnostics like (say) access control. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98806 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-17ActOnTagDefinitionError is supposed to 'unwind' ActOnTagStartDefinition, notJohn McCall
ActOnStartCXXMemberDeclaration. We haven't started the field collector on this class yet, so don't stop it. Fixes a crash in the VS buildbot and a memory error on all the others. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98760 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-17Clean up after ourselves when there's an error parsing the base clause.John McCall
Fixes the crash-on-invalid in PR6629. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98698 91177308-0d34-0410-b5e6-96231b3b80d8

that occur in constructors (on the unwind path). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98681 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15Remember declaration scope qualifiers in the AST. Imposes no memory overheadJohn McCall
on unqualified declarations. Patch by Enea Zaffanella! Minimal adjustments: allocate the ExtInfo nodes with the ASTContext and delete them during Destroy(). I audited a bunch of Destroy methods at the same time, to ensure that the correct teardown was being done. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98540 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-11Maintain type source information for functions through templateJohn McCall
instantiation. Based on a patch by Enea Zaffanella! 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
2010-03-10Create a new InjectedClassNameType to represent bare-word references to the John McCall
injected class name of a class template or class template partial specialization. This is a non-canonical type; the canonical type is still a template specialization type. This becomes the TypeForDecl of the pattern declaration, which cleans up some amount of code (and complicates some other parts, but whatever). Fixes PR6326 and probably a few others, primarily by re-establishing a few invariants about TypeLoc sizes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98134 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-08In C++98/03, an uninitialized variable that has POD class type will beDouglas Gregor
uninitialized. This seems not to be the case in C++0x, where we still call the (trivial) default constructor for a POD class (!). Previously, we had implemented only the C++0x rules; now we implement both. Fixes PR6536. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97928 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-07Fix for PR6294: we should only delay recording nested dynamic classes if theyEli Friedman
are lexically nested. Othewise, we never end up recording semantically nested classes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97900 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-02Diagnose the declaration of enum templates. Also, be a bit moreDouglas Gregor
careful about value-dependent enumerators. Fixes PR5786. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97570 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
2010-03-01Fix the lookup of names used in a friend declaration to not attempt toChandler Carruth
re-declare them. This fixes PR6317. Also add the beginnings of an interesting test case for p1 of [class.friend] which also covers PR6317. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97499 91177308-0d34-0410-b5e6-96231b3b80d8
