Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to eliminate partial-redundant vector loads. An example apparatus includes a node group to associate a vector operation with a node group based on a load type of the vector operation. The example apparatus also includes a candidate identifier to identify a candidate in the node group, the candidate to include a subset of vector operations of the node group. The example apparatus also includes a code optimizer to determine replacement code based on a characteristic of the candidate, and to compare an estimated cost associated with executing the replacement code to a threshold cost relative to a cost of executing the candidate. The example apparatus also includes a code generator to generate machine code using the replacement code when the estimated cost of executing the replacement code satisfies the threshold cost.
