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.

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. > =20 > Sean On 03/28/18 11:22, Sean Fertile wrote: > Hi Mark, > =20 > Just so we are clear this is about V1 abi support in lld, not in llvm. = The compiler will still be able to produce valid code for big-endian = ppc64. > =20 > Regards > Sean =20 =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
