Hi All, We would like to contribute our supports for Motorola 68000 series CPU (also known as M68k or M680x0) into LLVM. And we want to hear feedbacks from you Here is some background for M68k: Motorola 68000 series CPU was one of the most popular CPUs used by personal computers in the ‘80, including some of the earliest Apple Macintosh. Fast-forwarding to modern days, M68k is still popular among retroco...

Its awesome to see so much progress on this! A very minor question - why is it called M680x0 and not M68K given that's what the target arch/triple is and how its usually referred to? Sorry for the bikeshedding.... Simon. On 30/09/2020 21:14, Min-Yih Hsu via llvm-dev wrote: > Hi All, > > I've composed a draft roadmap for this new target. I've decided to try > Gi...

Each target community is responsible for maintaining their own buildbots. All we

We also had a simple roadmap here: https://github.com/M680x0/M680x0-mono-repo/projects Showing the prerequisites to become an experimental target and eventually, an official target. We're currently struggling on setting up the buildbot but I believe Adrian (CC-ed) is working on that. So I hope the patches can be sorted out while waiting for the buildbot....

Hi list, I'm toying with the idea of writing a m680x0 backend for LLVM, and the address modes of this chip are bewildering, to say the least. Here's a rough list off wikipedia for reference: * Register direct o data register, e.g. "D0" o address register, e.g. "A6" * Register indirect o S...
