Yes, the biggest thing you'll run into is that support for 32-bit (and, IIRC, big-endian) PowerPC is long gone from the Go compiler. Someone else on the golang-dev list was working on a port to a different embedded-ish 32-bit PPC implementation (440, if memory serves, but it often doesn't). You might want to check there to see if you can collaborate. There is also this tracking issue, which you may find instructive: https://github.com/golang/go/issues/22885 Of note to non-PPC people: the eXXX cores are generally similar to older commercial PowerPCs (i.e. the e300 was a derivative of the 603e, the e500 is somewhat similar to the 750/G3, but is more advanced). Support for specific cores is not quite as important as support for the overall ISA unless you are building an operating system, where they can differ greatly on the low-level details. Personally, I'd love to see 32-bit PPC support reinstated because I have a few boards I'd love to use with Net/OpenBSD and Go, but I don't have the time right now and it's not of commercial interest to me, so I can't get funding for it. - Dave -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
