Yeah, a lot has changed since last time I touched this. For example, rust toolchain now includes its own profiler runtime (albeit guarded by a feature flag), so building profiler-rt...

Asserts can be handled by generating a companion global struct for each c++ closure, which would store size/alignment of all of its arguments. The tricky bit seems to be knowing...

What if build script used `rustc` itself to parse the crate? (with a different implementation of the cpp! macro to collect c++ code). Additionally, I am thinking that rust-cpp might...

In my specific case, the struct was requested to be opaque, so maybe bindgen could use some other "filler" type? Looking at [cabi_x86_64.rs](https://github.com/rust-lang/rust/blob/master/src/librustc_trans/cabi_x86_64.rs), it seems that some kind on weird...

Looks like this does the trick (i.e. some struct member must be misaligned): ```rust #[repr(C, packed)] struct Bar { data1: u8, data2: u16, data3: [u8; 5], } ``` Would only...

As I've said in [IRLO thread](https://internals.rust-lang.org/t/bindgen-and-c/5434), I think there are two ways we can go here: - Add support for "significant-address" c++ types in rustc via an attribute. - Have...

@retep998: It seems to me that you are describing a different problem. Is there already an open issue for it? Let's take discussion there.

bindgen could also fix up function signatures if it generated a small wrapper function. For example: ```rust extern "C" { #[link_name = "..."] fn raw_ClassMethod(this: *mut Class, ret_value: *mut SomeStruct)...
