<p><span class="h-card" translate="no"><a href="https://mastodon.social/@barrelshifter" class="u-url mention">@<span>barrelshifter</span></a></span> this is now years ago, but I vividly recall how much resistance there was to adding rotates to LLVM IR too because &quot;can&#39;t you just build them out of simpler shifts?&quot;</p><p>(in short: yes, but not reliably for variable shifts; the patterns to match for rotates with variable shift amount are quite fragile and easily - and frequently - broken by unrelated opts in the middle end)</p>

<p>When I was a teenager, my career goals were to become a physicist or a neurosurgeon. Years later, I switched out physics for computer science and neurosurgery for neuroscience. Haha!</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Also I would like the moon on a stick, or a unicorn. </p><p>Seriously though, SWD + UART is a damn good achievement. Now I need to dig up a 1.27mm pitch 2x5 connector breakout. Maybe roll my own that plugs straight into a Glasgow IO bank.</p>

<p><span class="h-card" translate="no"><a href="https://aus.social/@jpm" class="u-url mention">@<span>jpm</span></a></span> yeah so the bus snoopers will have to wait a bit; multiplexing and flow control is hard</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Debug probe + UART (that both work reliably, unlike the WCH Link-E) is the dream. Debug probe + UART + bus snoopers would be magical.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> Phenomenonal! That’s really nice.</p>
