// a
namespace llvm { class GlobalValue; }
[modules] When performing a lookup into a namespace, ensure that any later redefinitions of that namespace have already been loaded. When writing out the names in a namespace, if we see a name that is locally declared and had imported declarations merged on top of it, export the local declaration as the lookup result, because it will be the most recent declaration of that entity in the redeclaration chain of an importer of the module. llvm-svn: 215518 2014-08-13 09:23:33 +08:00			`// a`
