Thanks a lot! Should I rebase on main to trigger a new CI run? I think this is not getting into the merge queue because of the failed CI. |
Don't require that the alignment of `size_t` equals pointer size when using the `size_t_is_usize` option. The purpose of this check was to make sure that `size_t` and `uintptr_t` are the same type, but the alignment and size don't have to match for that to be true. The code still checks that `size_t` has the same size as a pointer. Clang's C API doesn't expose the target pointer alignment, so just remove the assert. Fixes rust-lang#3312

I think it should work now. Thanks for the patch and the extra clippy fixes! |
