	PR tree-optimization/88031
	* tree-vect-loop.c (vectorizable_reduction): Move check
	for multiple types earlier so we get the expected dump.
	Simplify calls to vectorizable_condition.
	* tree-vect-stmts.h (vectorizable_condition): Update prototype.
	* tree-vect-stmts.c (vectorizable_condition): Instead of
	reduc_def and reduc_index take just a flag.  Simplify
	code-generation now that we can rely on the defs being set up.
	(vectorizable_comparison): Remove unused argument.

	* gcc.dg/pr88031.c: New testcase.
