* Allow unnamed_addr on declarations.Rafael Espindola2011-01-15

* Revamp the ValueMapper interfaces in a couple ways:Chris Lattner2011-01-08
| | | | | | | | | | | | | | | | | | 1. Take a flags argument instead of a bool. This makes it more clear to the reader what it is used for. 2. Add a flag that says that "remapping a value not in the map is ok". 3. Reimplement MapValue to share a bunch of code and be a lot more efficient. For lookup failures, don't drop null values into the map. 4. Using the new flag a bunch of code can vaporize in LinkModules and LoopUnswitch, kill it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123058 91177308-0d34-0410-b5e6-96231b3b80d8

* Reapply r112091 and r111922, support for metadata linking, with aDan Gohman2010-08-26
| | | | | | | | | | | | | | | fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112190 91177308-0d34-0410-b5e6-96231b3b80d8

* Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling2010-06-29
| | | | | | | | | | | | | | | | | | | | metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107205 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin2010-01-27
| | | | | | | | | | | | | | | | | | | | | | 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.

* Fixed linking of modules containing aliases to constant bitcasts. Existing ↵David Chisnall2010-01-09
| | | | | | | | | | behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee). Linking modules containing aliases to GEPs is still not quite right. GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break. Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93052 91177308-0d34-0410-b5e6-96231b3b80d8
