2008-05-09-Implement proper name lookup for namespaces.Argyrios Kyrtzidis
-identifierResolver exposes an iterator interface to get all decls through the scope chain. -The semantic staff (checking IdentifierNamespace and Doug's checking for shadowed tags were moved out of IdentifierResolver and back into Sema. IdentifierResolver just gives an iterator for all reachable decls of an identifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50923 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50906 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-09Extend vector member references to include {.hi, .lo, .e, .o} which return aNate Begeman
vector of the same element type and half the width, with the high, low, even, and odd elements respectively. Allow member references to member references, so that .hi.hi gives you the high quarter of a vector. This is fairly convenient syntax for some insert/extract operations. Remove some unnecessary methods/types in the ExtVectorElementExpr class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50892 91177308-0d34-0410-b5e6-96231b3b80d8
