Did you change Clang?

[Meghali Dhoble via swift-dev]

Thanks John, for the response.
We have a patch added already for ppc64 support at llvm, however still the
failures seen,
I will try to opt for 2nd  option and see if that helps.

 Thanks,
Meghali

I don't see anything like that in the log.  It looks like an ordinary
compiler error relating to our custom calling convention.

You need to either
1. implement swiftcc in LLVM's ppc64 backend and then teach Clang that it's
legal there or
2. configure Swift to not try to use it.

In the short term, I suspect that (2) is the right approach.  Graydon was
at least thinking about doing some work recently that would be aimed at
making it easier to do this kind of configuration; CC'ing him explicitly to
see if there's been progress there.

You need to either
1. implement swiftcc in LLVM's ppc64 backend and then teach Clang that it's 
legal there or
2. configure Swift to not try to use it.

In the short term, I suspect that (2) is the right approach.  Graydon was at
