ARM target code clean up. Check for iOS, not Darwin where it makes sense. llvm-svn: 146981

Enable sibling call optimization of libcalls which are expanded during legalization time. Since at legalization time there is no mapping from SDNode back to the corresponding LLVM instruction and the return SDNode is target specific, this requires a target hook to check for eligibility. Only x86 and ARM support this form of sibcall optimization right now. rdar://8707777 llvm-svn: 120501

Enable tail calls on ARM by default, with some basic tests. This has been well tested on Darwin but not elsewhere. It should work provided the linker correctly resolves B.W <label in other function> which it has not seen before, at least from llvm-based compilers. I'm leaving the arm-tail-calls switch in until I see if there's any problems because of that; it might need to be disabled for some environments. llvm-svn: 106299

Fix a long standing tail call optimization bug. When a libcall is emitted legalizer always use the DAG entry node. This is wrong when the libcall is emitted as a tail call since it effectively folds the return node. If the return node's input chain is not the entry (i.e. call, load, or store) use that as the tail call input chain. PR12419 rdar://9770785 rdar://11195178 llvm-svn: 154370

Correctly preserve the input chain for potential tailcall nodes whose return values are bitcasts. The chain had previously been being clobbered with the entry node to the dag, which sometimes caused other code in the function to be erroneously deleted when tailcall optimization kicked in. <rdar://problem/13827621> llvm-svn: 181696
