2009-03-04Finish up some fixes related to <rdar://problem/6497631> Message lookup is ↵Steve Naroff
sometimes different than gcc's. - Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch). - Tighten up lookup when messaging 'self'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Implement an important missing warning when a selectorFariborz Jahanian

2009-03-03Fix <rdar://problem/6497242> Inherited overridden protocol declared objects ↵Steve Naroff
don't work. Change Sema::DiagnosePropertyMismatch() to check for type compatibility (rather than type equivalence, which is too strict). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65949 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-01Fix <rdar://problem/6248764> parser rejects: bad receiver type 'CFStringRef'.Steve Naroff
Downgrade an error to a warning (for GCC compatibility). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65779 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Fix <rdar://problem/6614945> method not found. Steve Naroff
This was a fairly recent regression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65547 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-26Fix http://llvm.org/bugs/show_bug.cgi?id=3544.Steve Naroff
The code for looking up local/private method in Sema::ActOnInstanceMessage() was not handling categories properly. Sema::ActOnClassMessage() didn't have this bug. Created a helper with the correct logic and changed both methods to use it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65532 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner
The big difference here is that (like string literal) @encode has array type, not pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65391 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-23Remove isSuperExpr(), which ignores any casts on 'super'.Steve Naroff
I don't think casting super makes any sense (since it won't effect method lookup). Will discuss with other offline and decide what to do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65317 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65293 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-22Contains the following (related to problems found while investigting ↵Steve Naroff
<rdar://problem/6497631> Message lookup is sometimes different than gcc's). - Implement instance/class overloading in ObjCContainerDecl (removing a FIXME). This involved hacking NamedDecl::declarationReplaces(), which took awhile to figure out (didn't realize replace was the default). - Changed Sema::ActOnInstanceMessage() to remove redundant warnings when dealing with protocols. For now, I've omitted the "protocol" term in the diagnostic. It simplifies the code flow and wan't always 100% accurate (e.g. "Foo<Prot>" looks in the class interface, not just the protocol). - Changed several test cases to jive with the above changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65292 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-21More work to integrate newly added ObjCQualifiedClassType into the type system.Steve Naroff
This is necessary 'plumbing' to fix <rdar://problem/6497631> Message lookup is sometimes different than gcc's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65248 91177308-0d34-0410-b5e6-96231b3b80d8

interfaces more consistently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65138 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Downgrade complaints about calling unavailable functions to a warningDouglas Gregor
(as GCC does), except when we've performed overload resolution and found an unavailable function: in this case, we actually error. Merge the checking of unavailable functions with the checking for deprecated functions. This unifies a bit of code, and makes sure that we're checking for unavailable functions in the right places. Also, this check can cause an error. We may, eventually, want an option to make "unavailable" warnings into errors. Implement much of the logic needed for C++0x deleted functions, which are effectively the same as "unavailable" functions (but always cause an error when referenced). However, we don't have the syntax to specify deleted functions yet :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64955 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-18change the StringLiteral AST node to track all of the SourceLocations of Chris Lattner
the various PPTokens that are pasted together to make it. In the course of working on this, I discovered ParseObjCStringLiteral which needs some work. I'll tackle it next. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64892 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-15Refactor the deprecated and unavailable checks into a newChris Lattner
DiagnoseUseOfDeprecatedDecl method. This ensures that they are treated consistently. This gets us 'unavailable' support on a few new types of decls, and makes sure we consistently silence deprecated when the caller is also deprecated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64612 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-12Several cleanups:Steve Naroff
- rename isObjCIdType/isObjCClassType -> isObjCIdStructType/isObjCClassStructType. The previous name didn't do what you would expect. - add back isObjCIdType/isObjCClassType to do what you would expect. Not currently used, however many of the isObjCIdStructType/isObjCClassStructType clients could be converted over time. - move static Sema function areComparableObjCInterfaces to ASTContext (renamed to areComparableObjCPointerTypes, since it now operates on pointer types). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64385 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-07Overhaul of Stmt allocation:Ted Kremenek
- Made allocation of Stmt objects using vanilla new/delete a *compiler error* by making this new/delete "protected" within class Stmt. - Now the only way to allocate Stmt objects is by using the new operator that takes ASTContext& as an argument. This ensures that all Stmt nodes are allocated from the same (pool) allocator. - Naturally, these two changes required that *all* creation sites for AST nodes use new (ASTContext&). This is a large patch, but the majority of the changes are just this mechanical adjustment. - The above changes also mean that AST nodes can no longer be deallocated using 'delete'. Instead, one most do StmtObject->Destroy(ASTContext&) or do ASTContextObject.Deallocate(StmtObject) (the latter not running the 'Destroy' method). Along the way I also... - Made CompoundStmt allocate its array of Stmt* using the allocator in ASTContext (previously it used std::vector). There are a whole bunch of other Stmt classes that need to be similarly changed to ensure that all memory allocated for ASTs comes from the allocator in ASTContext. - Added a new smart pointer ExprOwningPtr to Sema.h. This replaces the uses of llvm::OwningPtr within Sema, as llvm::OwningPtr used 'delete' to free memory instead of a Stmt's 'Destroy' method. Big thanks to Doug Gregor for helping with the acrobatics of making 'new/delete' private and the new smart pointer ExprOwningPtr! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63997 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-06Move StringLiteral to allocate its internal string data using the allocator inTed Kremenek
ASTContext. This required changing all clients to pass in the ASTContext& to the constructor of StringLiteral. I also changed all allocations of StringLiteral to use new(ASTContext&). Along the way, I updated a bunch of new()'s in StmtSerialization.cpp to use the allocator from ASTContext& (not complete). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63958 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Some name-lookup-related fixes, from Piotr Rak!Douglas Gregor
- Changes Lookup*Name functions to return NamedDecls, instead of Decls. Unfortunately my recent statement that it will simplify lot of code, was not quite right, but it simplifies some... - Makes MergeLookupResult SmallPtrSet instead of vector, following Douglas suggestions. - Adds %qN format for printing qualified names to Diagnostic. - Avoids searching for using-directives in Scopes, which are not DeclScope, during unqualified name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63739 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-30Eliminated LookupCriteria, whose creation was causing a bottleneck forDouglas Gregor
LookupName et al. Instead, use an enum and a bool to describe its contents. Optimized the C/Objective-C path through LookupName, eliminating any unnecessarily C++isms. Simplify IdentifierResolver::iterator, removing some code and arguments that are no longer used. Eliminated LookupDeclInScope/LookupDeclInContext, moving all callers over to LookupName, LookupQualifiedName, or LookupParsedName, as appropriate. All together, I'm seeing a 0.2% speedup on Cocoa.h with PTH and -disable-free. Plus, we're down to three name-lookup routines. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63354 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-29Refactor Sema::LookupDecl() into 2 functions: LookupDeclInScope() and ↵Steve Naroff
LookupDeclInContext(). The previous interface was very confusing. This is much more explicit, which will be easier to understand/optimize/convert. The plan is to eventually deprecate both of these functions. For now, I'm focused on performance. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63256 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Remove 'NamespaceNameOnly' argument to Sema::LookupDecl(). It is unused.Steve Naroff
Even though Sema::LookupDecl() is deprecated, it's still used all over the place. Simplifying the interface will make it easier to understand/optimize/convert. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63210 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Split the single monolithic DiagnosticKinds.def file into oneChris Lattner
.def file for each library. This means that adding a diagnostic to sema doesn't require all the other libraries to be rebuilt. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63111 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Some micro-optimizations for DISABLE_SMART_POINTERS:Douglas Gregor
- When it's safe, ActionResult uses the low bit of the pointer for the "invalid" flag rather than a separate "bool" value. This keeps GCC from generating some truly awful code, for a > 3x speedup in the result-passing microbenchmark. - When DISABLE_SMART_POINTERS is defined, store an ActionResult within ASTOwningResult rather than an ASTOwningPtr. Brings the performance benefits of the above to smart pointers with DISABLE_SMART_POINTERS defined. Sadly, these micro-benchmark performance improvements don't seem to make much of a difference on Cocoa.h right now. However, they're harmless and might help with future optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63061 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-09Provide a new kind of iterator, the specific_decl_iterator, thatDouglas Gregor
filters the decls seen by decl_iterator with two criteria: the dynamic type of the declaration and a run-time predicate described by a member function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl considerably. It has no measurable performance impact. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61994 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-24Change a whole lot of diagnostics to take QualType's directly Chris Lattner
instead of converting them to strings first. This also fixes a bunch of minor inconsistencies in the diagnostics emitted by clang and adds a bunch of FIXME's to DiagnosticKinds.def. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59948 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of Chris Lattner
uses of getName() with uses of getDeclName(). This upgrades a bunch of diags to take DeclNames instead of std::strings. This also tweaks a couple of diagnostics to be cleaner and changes CheckInitializerTypes/PerformInitializationByConstructor to pass around DeclarationNames instead of std::strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59947 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Rename Selector::getName() to Selector::getAsString(), and addChris Lattner
a new NamedDecl::getAsString() method. Change uses of Selector::getName() to just pass in a Selector where possible (e.g. to diagnostics) instead of going through an std::string. This also adds new formatters for objcinstance and objcclass as described in the dox. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59933 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-23Convert IdentifierInfo's to be printed the same as DeclarationNames Chris Lattner
with implicit quotes around them. This has a bunch of follow-on effects and requires tweaking to a whole lot of code. This causes a regression in two tests (xfailed) by causing it to emit things like: Line 10: duplicate interface declaration for category 'MyClass1' ('Category1') instead of: Line 10: duplicate interface declaration for category 'MyClass1(Category1)' I will fix this in a follow-up commit. As part of this, I had to start switching stuff to use ->getDeclName() instead of Decl::getName() for consistency. This is good, but I was planning to do this as an independent patch. There will be several follow-on patches to clean up some of the mess, but this patch is already too big. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59917 91177308-0d34-0410-b5e6-96231b3b80d8
