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.

Does anyone know of an inexpensive ARM aarch64 SBC that has a dedicated JTAG port? That is, one that doesn't multiplex with the SD slot and stays enabled after normal boot (or can be easily kept enabled without uboot recompile)?

Dites les toulousains, j'ai un #quartz64 à la maison et je n'arrive pas à installer d'OS dessus, le port console n'a pas l'air de fonctionner, mais je suis un vrai #noob là-dedans. Je cherche une install party ou quelqu'un qui aurait de l'expérience et qui pourrait m'aider à boostraper la chose.

le repouet aide calme l'esprit.
