static bool
propagate_alignment_accross_jump_function (struct cgraph_edge *cs,
struct ipa_jump_func *jfunc,
struct ipcp_param_lattices
*dest_lat){
if (alignment_bottom_p (dest_lat))
return false;
ipa_alignment cur;
cur.known = false;
if (jfunc->alignment.known)
cur = jfunc->alignment;
Does it skip a jump func when its argument alignment is unknown?
Shouldn't propagate_alignment_accross_jump_function keeps the
minimum argument alignment, not the maximum argument alignment?
