PR tree-optimization/55281
* tree-vect-generic.c (expand_vector_condition): Accept any
is_gimple_val rather than just SSA_NAME if not COMPARISON_CLASS_P.
* fold-const.c (fold_ternary_loc): Fold VEC_COND_EXPR if arg0 is
either integer_all_onesp or integer_zerop.
* tree-vect-stmts.c (vectorizable_condition): Build the condition
using corresponding vector integer type instead of vectype.
* gcc.dg/vect/fast-math-pr55281.c: New test.
* g++.dg/opt/pr55281.C: New test.
