* Enable sibling call optimization of libcalls which are expanded duringEvan Cheng2010-11-301-0/+18
| | | | | | | | | | | 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
