[DAGTypeLegalizer] Handle SIGN/ZERO_EXTEND in WidenVecRes_Convert(). 2017-01-27T07:46:26+00:00 Jonas Paulsson paulsson@linux.vnet.ibm.com 2017-01-27T07:46:26+00:00 bb0ed3e732aff72f44ef76733fdf79c043cbb5b9 In case of a SIGN/ZERO_EXTEND of an incomplete vector type (using only a partial number of available vector elements), WidenVecRes_Convert() used to resort to scalarization. This patch adds a handling of the (common) case where an input vector can be found of same width as the widened result vector, by converting the node to SIGN/ZERO_EXTEND_VECTOR_INREG.

In case of a SIGN/ZERO_EXTEND of an incomplete vector type (using only a
partial number of available vector elements), WidenVecRes_Convert() used to
resort to scalarization.

This patch adds a handling of the (common) case where an input vector can be
found of same width as the widened result vector, by converting the node to
SIGN/ZERO_EXTEND_VECTOR_INREG.
