2010-04-11fix PR6811 by not parsing 'super' as a magic expression inChris Lattner
LookupInObjCMethod. Doing so allows all sorts of invalid code to slip through to codegen. This patch does not change the AST representation of super, though that would now be a natural thing to do since it can only be in the receiver position and in the base of a ObjCPropertyRefExpr. There are still several ugly areas handling super in the parser, but this is definitely a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100959 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-10Diagnose misordered initializers in constructor templates immediately instead ofJohn McCall
when they're instantiated. Merge the note into the -Wreorder warning; it doesn't really contribute much, and it was splitting a thought across diagnostics anyway. Don't crash in the parser when a constructor's initializers end in a comma and there's no body; the recovery here is still terrible, but anything's better than a crash. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100922 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-02Fix an amusing typo that completely the re-introduction of parametersDouglas Gregor
for the purposes of parsing default arguments. In effect, we would re-introduce the parameter with a default argument N times (where N is the number of parameters preceding the parameter with a default argument). This showed up when a defaulted parameter of a member function of a local class shadowed a parameter of the enclosing function. Fixes PR6383. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97534 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-01When we're parsing template names as part of base-specifiers, we areDouglas Gregor

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
