Gets the hash to index the table, using the pc of the branch, and the index of the table.
- Parameters
-
tid Thread ID of the branch pc address of the branch pc2 address of the branch shifted 2 bits to the right t integer index of the table
- Returns
- resulting hash value that will be used to index the table
