re PR tree-optimization/32216 (ICE: verify_stmts failed (invalid reference prefix) with -ftree-vectorize)
PR tree-optimization/32216
* tree-vectorizer.c (supportable_widening_operation): Determine
signedness of FIX_TRUNC_EXPR from output operand.
(supportable_narrowing_operation): Ditto.
* tree-vect-generic.c (expand_vector_operations_1): Determine
signedness of VEC_UNPACK_FLOAT_HI_EXPR and VEC_UNPACK_FLOAT_LO_EXPR
from input operand.
testsuite/ChangeLog:
PR tree-optimization/32216
* gcc.dg/vect/pr32216.c: New test.
