* Rename "Release" builds as "Release+Asserts"; rename "Release-Asserts"Duncan Sands2010-07-071-1/+1
| | | | | | | | | | | | | builds to "Release". The default build is unchanged (optimization on, assertions on), however it is now called Release+Asserts. The intent is that future LLVM releases released via llvm.org will be Release builds in the new sense, i.e. will have assertions disabled (currently they have assertions enabled, for a more than 20% slowdown). This will bring them in line with MacOS releases, which ship with assertions disabled. It also means that "Release" now means the same things in make and cmake builds: cmake already disables assertions for "Release" builds AFAICS. llvm-svn: 107758

* Implement the "linker_private_weak" linkage type. This will be used forBill Wendling2010-07-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Objective-C metadata types which should be marked as "weak", but which the linker will remove upon final linkage. However, this linkage isn't specific to Objective-C. 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". Currently only supported on Darwin platforms. llvm-svn: 107433
