2010-03-02Suppress implicit member redeclarations arising from explicit instantiationJohn McCall
declarations after the member has been explicitly specialized. We already did this after explicit instantiation definitions; not doing it for declarations meant that subsequent definitions would see a previous member declaration with specialization kind "explicit instantiation decl", which would then happily get overridden. Fixes PR 6458. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97605 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-02[CFG]Ted Kremenek
After discussion with Zhongxing, don't force the initializer of DeclStmts to be block-level expressions. This led to some interesting fallout: [UninitializedValues] Always visit the initializer of DeclStmts (do not assume they are block-level expressions). [BasicStore] With initializers of DeclStmts no longer block-level expressions, this causes self-referencing initializers (e.g. 'int x = x') to no longer cause the initialized variable to be live before the DeclStmt. While this is correct, it caused BasicStore::RemoveDeadBindings() to prune off the values of these variables from the initial store (where they are set to uninitialized). The fix is to back-port some (and only some) of the lazy-binding logic from RegionStore to BasicStore. Now the default values of local variables are determined lazily as opposed to explicitly initialized. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97591 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-02Inspired by seeing "MIPS" go by in the commits, I've gone ahead andJohn McCall
implemented a (codegen) target hook for __builtin_extend_pointer. I'm also making it return a uint64_t instead of an unsigned word; this comports with typical usage (i.e. the one use I know of). I don't know if any of the existing targets requires this hook to be set (other than x86 and x86_64, which I know do not). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97547 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.

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
