Function Documentation

tree_to_vec_perm_builder()

bool tree_to_vec_perm_builder	(	vec_perm_builder *	builder,
		tree	cst )

Try to read the contents of VECTOR_CST CST as a constant permutation
vector.  Return true and add the elements to BUILDER on success,
otherwise return false without modifying BUILDER.

tree_to_vec_perm_indices()

bool tree_to_vec_perm_indices	(	vec_perm_indices *	indices,
		tree	op0,
		tree	op1,
		tree	perm_cst )

Try to read the contents of VECTOR_CST PERM_CST as a constant permutation
vector permuting OP0 and OP1.  Return true and populate INDICES on success,
otherwise return false without modifying INDICES.

vec_perm_indices_to_rtx()

rtx vec_perm_indices_to_rtx	(	machine_mode	mode,
