2012-01-13A few minor improvements to error recovery trying to access member of a ↵Eli Friedman
function. In particular, this restores the cool error recovery for the example from http://blog.llvm.org/2010/04/amazing-feats-of-clang-error-recovery.html , which regressed a few months back. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148089 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-07More lambda work: semantic analysis of capturing 'this'. It's a bit ↵Eli Friedman
complicated, but we have to be careful about when exactly captures are marked given PotentiallyPotentiallyEvaluated contexts. (Actually, it's not 100% correct yet, but it's close enough for the moment.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147723 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-02Diagnose cases where the definition of a particular type is required,Douglas Gregor
is known (to Clang), but is not visible because the module has not yet been imported. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147436 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-20Unlike in C++03, a constant-expression is not an unevaluated operand in C++11.Richard Smith
Split out a new ExpressionEvaluationContext flag for this case, and don't treat it as unevaluated in C++11. This fixes some crash-on-invalids where we would allow references to class members in potentially-evaluated constant expressions in static member functions, and also fixes half of PR10177. The fix to PR10177 exposed a case where template instantiation failed to provide a source location for a diagnostic, so TreeTransform has been tweaked to supply source locations when transforming a type. The source location is still not very good, but MarkDeclarationsReferencedInType would need to operate on a TypeLoc to improve it further. Also fix MarkDeclarationReferenced in C++98 mode to trigger instantiation for static data members of class templates which are used in constant expressions. This fixes a link-time problem, but we still incorrectly treat the member as non-constant. The rest of the fix for that issue is blocked on PCH support for early-instantiated static data members, which will be added in a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146955 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-15Replace all comparisons between ObjCInterfaceDecl pointers with callsDouglas Gregor
to declaresSameEntity(), as a baby step toward tracking forward declarations of Objective-C classes precisely. Part of <rdar://problem/10583531>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146618 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-27Fix some cases where a CK_IntegralCast was being used to convert an lvalue to anRichard Smith
rvalue. An assertion to catch this is in ImpCastExprToType will follow, but vector operations currently trip over this (due to omitting the usual arithmetic conversions). Also add an assert to catch missing lvalue-to-rvalue conversions on the LHS of ->. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143155 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-26Pull out conversion on LHS of -> and . into its own function. This happensRichard Smith
implicitly in LookupMemberExpr and explicitly in cases where template instantiation doesn't redo the lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@143046 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Restore r142914 and r142915, now with missing file and apparentJohn McCall
GCC compiler workaround. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142931 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Revert r142914 and r142915, due to possibly missing file.NAKAMURA Takumi
r142914: "Introduce a placeholder type for "pseudo object"" r142915: "Pull the pseudo-object stuff into its own file." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142921 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25Introduce a placeholder type for "pseudo object"John McCall
expressions: expressions which refer to a logical rather than a physical l-value, where the logical object is actually accessed via custom getter/setter code. A subsequent patch will generalize the AST for these so that arbitrary "implementing" sub-expressions can be provided. Right now the only client is ObjC properties, but this should be generalizable to similar language features, e.g. Managed C++'s __property methods. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142914 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-18Make it possible to compute the type of 'this' without capturingDouglas Gregor
it. Refactoring to be used in a moment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142360 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-17obj-c++: Fix a IRGen crash when getter is a reference type.Fariborz Jahanian
Fix is in Sema. // rdar://10153365 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142249 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-11Catch placeholder types in DefaultLvalueConversionJohn McCall
and DefaultFunctionArrayLvalueConversion. To prevent significant regression for should-this-be-a-call fixits, and to repair some such regression from the introduction of bound member placeholders, make those placeholder checks try to build calls appropriately. Harden the build-a-call logic while we're at it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141738 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-10Don't complain about qualified property or ivar access when theDouglas Gregor
qualifier itself is invalid. Crasher noticed by Fariborz. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141544 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-09Diagnose attempts to qualify the name of an instance variable orDouglas Gregor
property in an Objective-C++ member access expression. Fixes PR9759. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@141522 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-19Rename SourceLocation::getFileLocWithOffset -> getLocWithOffset.Argyrios Kyrtzidis
It already works (and is useful with) macro locs as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140057 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139987 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-11Encapsulate the Objective-C id/Class/SEL "redefinition" types inDouglas Gregor
ASTContext with accessors/mutators. The only functional change is that the AST writer won't bother writing the id/Class/SEL redefinition type if it hasn't been explicitly set; previously, it ended up being written as a synonym for the built-in id/Class/SEL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137349 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28Switch Sema::ExtVectorDecls over to LazyVector.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136314 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-23remove unneeded llvm:: namespace qualifiers on some core types now that ↵Chris Lattner
LLVM.h imports them into the clang namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135852 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-28Add support for C++ namespace-aware typo correction, e.g., correctingDouglas Gregor
vector<int> to std::vector<int> Patch by Kaelyn Uhrain, with minor tweaks + PCH support from me. Fixes PR5776/<rdar://problem/8652971>. Thanks Kaelyn! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134007 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-28Provide fix-it for '.' <-> '->' for Objective-C ivar/property access.Fariborz Jahanian
// rdar://7811841 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133970 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-23Move all of Sema's member-access-related checking out of SemaExpr.cppDouglas Gregor
and into a new file, SemaExprMember.cpp, bringing SemaExpr.cpp just under 10,000 lines of code (ugh). No functionality change, although I intend to do some refactoring of this code to address PR8368 at some point in the "near" future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133674 91177308-0d34-0410-b5e6-96231b3b80d8
