It didn't handle sign-extension properly in the case where the source integer is smaller than a pointer size. And, it relied on an assumption about sizeof(i8). The Analysis constant folder still folds these kinds of things; it has access to TargetData, so it can do them right. Add a testcase which tests that the VMCore constant folder doesn't miscompile this, and that the Analysis folder does fold it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94750 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin2010-01-2762-720/+624
| | | | | | | | | | | | | | | | | | | | | | Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.
