Tracking rustc bugs/features/RFCs that affect bindgen #849

Open fitzgen opened 7 years ago

fitzgen commented 7 years ago

This is a meta issue tracking rustc bugs and features that impact bindgen.

Appropriate things to list here would be either

RFCs proposing some feature that bindgen can leverage to emit better bindings, or
issues detailing rustc bugs we need fixed as a prerequisite to fixing bugs in our emitted bindings, or
pull requests adding new features that enable us to emit new kinds of bindings we haven't been able to before.

FYI: the system V AMD64 ABI will be stabilized in rustc 1.24

Thanks for the heads up!

As @upsuper pointed out, it looks like repr(align = "N") is being stabilized: https://github.com/rust-lang/rust/pull/47006

I'm not sure what version it will hit stable in.

From the PR:

(accepted, repr_align, "1.24.0", Some(33626)),

Dr-Emann commented 5 years ago

As of Rust 1.28, #[repr(transparent) is stable.

LegNeato commented 5 years ago

As of Rust 1.33, #[repr(packed(N))] is stable.
