2010-04-26Make the static type of the exception variable in an Objective-CDouglas Gregor
@catch a VarDecl. The dynamic type is still a ParmVarDecl, but that will change soon. No effective functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102341 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23Rework Parser-Sema interface for Objective-C @catch exception objectDouglas Gregor
arguments. Rather than having the parser call ActOnParamDeclarator (which is a bit of a hack), call a new ActOnObjCExceptionDecl action. We'll be moving more functionality into this handler to perform earlier checking of @catch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102222 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Keep track of the actual storage specifier written on a variable orDouglas Gregor
function declaration, since it may end up being changed (e.g., "extern" can become "static" if a prior declaration was static). Patch by Enea Zaffanella and Paolo Bolzoni. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101826 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15Audit uses of Sema::LookupSingleName for those lookups that areDouglas Gregor
intended for redeclarations, fixing those that need it. Fixes PR6831. This uncovered an issue where the C++ type-specifier-seq parsing logic would try to perform name lookup on an identifier after it already had a type-specifier, which could also lead to spurious ambiguity errors (as in PR6831, but with a different test case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101419 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Feed proper source-location information into Sema::LookupSingleResult,Douglas Gregor

2010-04-14Teach typo correction about various language keywords. We can'tDouglas Gregor
generally recover from typos in keywords (since we would effectively have to mangle the token stream). However, there are still benefits to typo-correcting with keywords: - We don't make stupid suggestions when the user typed something that is similar to a keyword. - We can suggest the keyword in a diagnostic (did you mean "static_cast"?), even if we can't recover and therefore don't have a fix-it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101274 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-12Split Sema logic for ObjC @property and @synthesize intoTed Kremenek
a separate file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98317 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-11For ivars created using @synthesize, set their DeclContext to beTed Kremenek
the @implementation (instead of the @interface) and actually add the ivar to the DeclContext (which we weren't doing before). This allows us to simplify ASTContext::CollectNonClassIvars() by removing ASTContext::CollectProtocolSynthesizedIvars(). Now all ivars can be found by either inspecting the ObjCInterfaceDecl and its companion ObjCImplementationDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98280 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

2010-01-16Improve location information for Objective-C category declarations. WeDouglas Gregor
previously only had a single location (the @ in @interface); now we know where the @ is (for the start of the declaration), where the class name is (that's the normal "location" now for diagnostics), and where the category name is. Also, eliminated the redundant "end" location, since ObjCContainerDecl already has better @end information. The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught CIndex how to use the new locations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93639 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-07Change ObjCContainerDecl to contain the entire range for the '@end'Ted Kremenek
piece of the declaration. The '@' and the 'end' are separate tokens, and require two SourceLocations to accurately track. This change was motivated because ObjCContainerDecl::getSourceRange() would previously not return the entire range of the declaration (the 'end' would be left off). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@92891 91177308-0d34-0410-b5e6-96231b3b80d8
