12:13:06beachSpeaking of ACM, we should soon be given our notifications.
13:51:24beachSo the FIXNUM-DIVIDE-INSTRUCTION has two inputs and two outputs. I want the first input to be in RAX and the second input in anything but RAX or RDX, and I want RDX to be unattributed.
13:51:25beachThen I want the first output to be in RDX and the second output to be in RAX. So I need to start by checking whether the second input has a register attributed to it. And if it is either RAX or RDX, I need to move it to a different register. etc, etc.
15:49:48beachI don't understand the question. At the moment SICL is just an end-user application. The registers that are visible to end-user applications can all be used.
18:09:22beachebrasca: Very quickly (I am off for today). First x86-64, just because that's what I have. I hope to be able to acquire a RISC-V machine in the not-too-far future, so that would be an obvious one. I think for the other architectures, I will rely on other people to write and support backends.
