"usual deallocation function" with two arguments. CodeGen will have to handle this case specifically, since the value for the second argument (the size of the allocated object) may have to be computed at run time.

purpose of overload resolution is to be treated as a uner-defined conversion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83004 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-28Teach Sema::isDeclInScope to handle overload sets constructed fromDouglas Gregor
functions that occur in multiple declaration contexts, e.g., because some were found via using declarations. Now, isDeclInScope will build a new overload set (when needed) containing only those declarations that are actually in scope. This eliminates a problem found with libstdc++'s <iostream>, where the presence of using In the longer term, I'd like to eliminate Sema::isDeclInScope in favor of better handling of the RedeclarationOnly flag in the name-lookup routines. That way, name lookup only returns the entities that matter, rather than taking the current two-pass approach of producing too many results and then filtering our the wrong results. It's not efficient, and I'm sure that we aren't filtering everywhere we should be. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82954 91177308-0d34-0410-b5e6-96231b3b80d8
