Alex Bradbury 0092df0669 [RISCV] Add target DAG combine for bitcast fabs/fneg on RV32FD ... DAGCombiner::visitBITCAST will perform: fold (bitconvert (fneg x)) -> (xor (bitconvert x), signbit) fold (bitconvert (fabs x)) -> (and (bitconvert x), (not signbit)) As shown in double-bitmanip-dagcombines.ll, this can be advantageous. But RV32FD doesn't use bitcast directly (as i64 isn't a legal type), and instead uses RISCVISD::SplitF64. This patch adds an equivalent DAG combine for SplitF64. llvm-svn: 352247		2019-01-25 21:55:48 +00:00
