options, which don't appear to be useful. -enable-mips-absolute-call is completely unused (and unless I'm mistaken, is supposed to have the same effect that -relocation-model=dynamic-no-pic should have), and -disable-mips-abicall appears to be effectively a synonym for -relocation-model=static. Adjust the few users of hasABICall to checks which seem more appropriate. Update MipsSubtarget, MipsTargetMachine, and MipselTargetMachine to synchronize with recent changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77938 91177308-0d34-0410-b5e6-96231b3b80d8
