From LLVM: I got a note that LLVM plans to remove PPC64's V1 abi support; I'm asked about what support there is for the PPC64 little-endian/V2 abi (see forwarded message)

Sean Fertile's messages are showing up empty on the list.
So I'm just forwarding the two that I've gotten to the lists
(and not the individuals). I think they stand fairly well on
their own, so no other message history is included.

> This is specifically the V1 abi support in the 64-bit PowerPC target in lld.  I'm definitely guilty of conflating big-endian with V1-abi and little-endian with V2-abi. I wasn't aware of people using the V2 abi on big-endian machines. We can make sure to test big-endian in lit tests as we deliver support for the V2 abi, but its unlikely I'll be able to run big-endian programs on actual hardware . I agree that we should keep it simple to add back the V1 abi support.
