[llvm-commits] Patch: small fix to bit convert and shifts

[Mon Ping Wang]

Hi,

This is a small patch that fixes two problems in SelectionDAG.cpp

   1) in getShuffleScalarElt, the code assumes that if the input to  
the shuffle is a BIT_CONVERT, the input to the bit convert is also a  
vector.  This is not necessarily true as it is legal to bit convert a

   2) In getNode, the code assumes that for shifts, the shift amount  
is always a scalar.  Since shifts can operate also on vectors, this  
assumption is not correct.
