    <p>It is common mantra nowadays: "C/C++ compilers generate better code than hand written assembly." or "Compilers generate code that is as good and often better than could be written by hand."</p> <p>But how we know this is true? Are there some valuable studies about HLL compiler code quality? I would like to read some works on this subject and not only for C/C++ but for other languages as well.</p> <p>Thanks</p> <p><strong>EDIT</strong>: I am asking not for discussion on this subject, nor for personal opinions or thoughts. I am asking about <strong>references</strong> to studies about the subjects. Such studies definitely <strong>must</strong> contains some experimental or theoretical work on the subject that can be verified.</p> <p>Please, if you don't have such information, simply don't answer this question. I already know all your thoughts on this subject. </p>

    1. COA _few_ people on Earth beat Deep Blue, a _few_ people on Earth could write better code than mainstream compilers. Are you one of them? That's the question...

    3. COI am not a student (graduated more than 20 year ago). I am writing [big assembly projects](http://fresh.flatassembler.com) and I am confident, assembly written programs are always superior. But I am trying to understand why this happens. It is strange, if the above statements about the C/C++ compiler code is true.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
