To enable a load of a call address to be folded with that call, this load is moved from outside of callseq into callseq. Such a moving adds a non-glued node (that load) into a glued sequence. This non-glue load is only removed when DAG selection folds them into a memory form call instruction. When such instruction selection is disabled, it breaks DAG schedule. To prevent that, such moving is disabled when target favors register indirect call. Previous workaround disabling CALL32m/CALL64m insn selection is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178308 91177308-0d34-0410-b5e6-96231b3b80d8
