Only through segmentation hacks right? In page table entries, execute doesn’t have a separate flag but shares it with read.

  execute disable was added with the pentium 4 (but needs pae page tables)

    Yes, but execute disable is not the same as execute only. AFAIK there's no way to prevent executable pages from being readable using only the i386/amd64 page table.

      You can fudge it with protection keys (poorly), and you can do it for real with EPT tricks.
