That&#x27;s about the best description I could find, too. It all boils down to what <i>&#x27;comply fully&#x27;</i> means.<p>Given the lego-like structure of the ARM instruction set (the 32-bit variant), with zillions of extensions (Jazelle, DSP instructions, Neon, Thumb, Thumb-2, various revisions of vector floating point instructions) and explicit support for &quot;coprocessors&quot; (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ARM_architecture#Coprocessors" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ARM_architecture#Coprocessors</a>), I suspect (based on common sense and nothing else) that the license allows expanding the instruction set and dropping whole modules.<p>But as I said elsewhere: concrete proof for that is lacking.
