Methods and apparatus to eliminate partial-redundant vector loads

A method for eliminating partial-redundant vector load operations, the method comprising:

• associating a vector operation with a node group based on a load type of the vector operation;
• identifying a candidate in the node group, the candidate including a subset of vector operations of the node group;
• determining replacement code based on a characteristic of the candidate;
• comparing an estimated cost associated with executing the replacement code to a threshold cost relative to a cost of executing the candidate;
• and
• based on the comparison, generating machine code using the replacement code when the estimated cost of executing the replacement code satisfies the threshold cost.

At least one computer readable storage medium comprising instructions that, when executed, cause a machine to at least:

• associate a vector operation with a node group based on a load type of the vector operation;
• identify a candidate in the node group, the candidate to include a subset of vector operations of the node group;
• determine replacement code based on a characteristic of the candidate;
• compare an estimated cost associated with executing the replacement code to a threshold cost relative to a cost of executing the candidate;
• and
• generate machine code using the replacement code when the estimated cost of executing the replacement code satisfies the threshold cost.
