Duncan Sands a3da922a27 Don't trivially delete unused calls to llvm.invariant.start. This allows ... llvm.invariant.start to be used without necessarily being paired with a call to llvm.invariant.end. If you run the entire optimization pipeline then such calls are in fact deleted (adce does it), but that's actually a good thing since we probably do want them to be zapped late in the game. There should really be an integration test that checks that the llvm.invariant.start call lasts long enough that all passes that do interesting things with it get to do their stuff before it is deleted. But since no passes do anything interesting with it yet this will have to wait for later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86840 91177308-0d34-0410-b5e6-96231b3b80d8		2009-11-11 15:34:13 +00:00
