New #blog post alert!
I muse about research some of my grad students and I did around independently evaluating some #OpenBSD anti-ROP mitigations, and I bid farewell to being an OpenBSD developer.

New #blog post. Let's write a peephole optimizer for #QBE that operates on #AArch64 assembly code. Three years ago, we did this for #AMD64 assembly code. But now that I have Arm machines, we can replicate the effort for another CPU architecture.

You ever buy a Blu ray of a TV show on a whim, figure you'll watch one episode, then end up watching the whole thing in one sitting, only to realize that while you did also buy the second season, you won't have it for a week.
This is me right now 
@alanc I mention in the blog post my disbelief that GNAT had no general Solaris support. It really just seemed a case of no one tried gave way to people assumed it didn't work gave way to ossified "knowledge" that was in fact incorrect. And it takes someone to try to break the ossification, which I was happy to do.
(As an aside, I notice Solaris doesn't ship a gdc package. It would be trivial to add it as D already supports Solaris. If it's something I can do let me know and I will try to figure out IPS packaging.)
