- MBB address is only valid as an immediate value in Small & Static code/relocation models. On other models, LEA is needed to load IP address of the restore MBB. - A minor fix of MBB in MC lowering is added as well to enable target relocation flag being propagated into MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166084 91177308-0d34-0410-b5e6-96231b3b80d8
