Hi, I'm the maintainer of pixman in MacPorts. I just updated our pixman port to 0.26.0. Unfortunately I now find that it does not build with clang 3.0:
fatal error: error in backend: Unsupported asm: input constraint with a matching output constraint of incompatible type!
It appears this problem was known to the developers of pixman in February:
I see that various fixes were committed, then reverted when it was reported that clang 3.1 would no longer have this problem.
That's nice, but Apple has not yet released a version of Xcode containing clang 3.1, and even once they do, I would want to continue to support the use of older Xcode versions for the foreseeable future.
What patch should we apply to make pixman 0.26.0 compile with clang 3.0?
