An Internal Compiler Error (ICE) occurring within the vect_create_constant_vectors function has been resolved. The issue stemmed from a mismatch in the node being checked within vect_slp_analyze_node_operations, leading to subsequent errors. This fix ensures the correct node is evaluated, preventing the ICE and improving the reliability of the vectorization pass.
