2012-07-24Comment parsing: couple TextTokenRetokenizer and comment parser together toDmitri Gribenko
remove one of the two variable-length lookahead buffers. Now retokenizer will ask for more tokens when it needs them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160680 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-24Introduces a new concept for binding results to matchersManuel Klimek
as per Chandler's request: - introduces a new matcher base type BindableMatcher that provides the bind() call - makes all dynamic-cast matcher creation functions return BindableMatchers; the special case about dynamic-cast matchers is that the node they match on and the node their child matchers match on are the same node, just casted to a different type; thus, there is no ambiguity on what bind() matches on; additionally, those are the matchers that we name with nouns in the matcher language, so it's easy for users to intuitively know which matchers are bindable To make this change possible, we got rid of a non-orthogonal implementation of thisPointerType, which had an implicit dynamic-cast matcher from CallExpr to CXXMemberCallExpr; as alternative, we now provide a memberCall dynamic-cast matcher and thisPointerType is a predicate on CXXMemberCallExpr. Last, the ArgumentAdaptingMatcher is actually not required for the implementation of makeDynCastAllOfComposite - this simplification makes it more obvious where the bind() call can be used based on the matcher creation function types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160673 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-23Add diagnostics for comma at end of enum and for extra semicolon at namespaceRichard Smith
scope to -Wc++11-extensions. Move extra semicolon after member function definition diagnostic out of -pedantic, since C++ allows a single semicolon there. Keep it in -Wextra-semi, though, since it's still questionable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160618 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-22PR12917: Remove incorrect assumption that lambda mangling information cannotRichard Smith
change once it's been assigned. It can change in two ways: 1) In a template instantiation, the context declaration should be the instantiated declaration, not the declaration in the template. 2) If a lambda appears in the pattern of a variadic pack expansion, the mangling number will depend on the pack length. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160614 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-20Add a new flag, -fms-inline-asm, that enables the output of MS-style inlineChad Rosier
assembly. By default, we don't emit IR for MS-style inline assembly (see r158833 as to why). This is strictly for testing purposes and should not be enabled with the expectation that things will work. This is a temporary flag and will be removed once MS-style inline assembly is fully supported. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160573 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-19For varargs, diagnose passing ObjC objects by value like other non-POD types.Jordan Rose
While we still want to consider this a hard error (non-POD variadic args are normally a DefaultError warning), delaying the diagnostic allows us to give better error messages, which also match the usual non-POD errors more closely. In addition, this change improves the diagnostic messages for format string argument type mismatches by passing down the type of the callee, so we can say "variadic method" or "variadic function" appropriately. <rdar://problem/11825593> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160517 91177308-0d34-0410-b5e6-96231b3b80d8

Panzer. I've not been able to trigger a failure caused by this, so no test yet.

2012-07-18[analyzer] Combine all ObjC message CallEvents into ObjCMethodCall.Jordan Rose
As pointed out by Anna, we only differentiate between explicit message sends This also adds support for ObjCSubscriptExprs, which are basically the same as properties in many ways. We were already checking these, but not emitting nice messages for them. This depends on the llvm::PointerIntPair change in r160456. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160461 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Rename addExtraInvalidatedRegions to get...RegionsJordan Rose
Per Anna's comment that "add..." sounds like a method that modifies the receiver, rather than its argument. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160460 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Make CallEvent a value object.Jordan Rose
We will need to be able to easily reconstruct a CallEvent from an ExplodedNode for diagnostic purposes, and that's exactly what factory functions are for. CallEvent objects are small enough (four pointers and a SourceLocation) that returning them through the stack is fairly cheap. Clients who just need to use existing CallEvents can continue to do so using const references. This uses the same sort of "kind-field-dispatch" as SVal, though most of the nastiness is contained in the DISPATCH and DISPATCH_ARG macros at the end of the file. (We can't use a template for this because member-pointers to base class methods don't call derived-class methods even when casting to the derived class. We can't use variadic macros because they're a C99 feature.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160459 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18[analyzer] Remove obsolete ObjCPropRef SVal kind.Jordan Rose
ObjC properties are handled through their semantic form of ObjCMessageExprs and their wrapper PseudoObjectExprs, and have been for quite a while. The syntactic ObjCPropertyRefExprs do not appear in the CFG and are not visited by ExprEngine. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160458 91177308-0d34-0410-b5e6-96231b3b80d8

and a function template instantiation, if there's a parameter pack in the declaration and one at the same place in the instantiation, don't assume that the pack wasn't expanded -- it may have expanded to nothing. Instead, go ahead and check whether the parameter pack was expandable. We can do this as a side-effect of the work we'd need to do anyway, to find how many parameters were produced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160416 91177308-0d34-0410-b5e6-96231b3b80d8
