  Changed paths:
    M llvm/lib/CodeGen/SelectionDAG/TargetLowering.cpp
    M llvm/test/CodeGen/X86/is_fpclass-fp80.ll
    M llvm/test/CodeGen/X86/is_fpclass.ll

  Log Message:
  DAG: Check isCondCodeLegal in is_fpclass expansion to fcmp eq 0

Results in some x86 codegen diffs. Some look better, some look worse.
