I kind of liked reusing the VkAttachmentReference struct instead of
having to roll our own. What do you think about creating helper
functions, like the following instead:
static bool is_color_attachment(struct anv_subpass* subpass,
VkAttachmentReference* att_ref)
{
return att_ref >= subpass->color_attachments &&
att_ref < subpass->color_attachments + subpass->color_count;
}
