What arguments are you passing to clang?

[ignatenkobrain]

how can I find out this? I just ran cargo test --release

[auscompgeek]

Oh, I thought you were talking about tests that bindgen generates, not the tests in the repo.

@ignatenkobrain I think those tests as written are little-endian-specific. We have integration tests in bindgen-integration which should work in big-endian platforms. Will patch bindgen so the tests aren't run on big-endian platforms.
