Incorrect link_name is generated for extern "C" functions for 32 bit linux

[chengchangwu]

Like #728, but for 32 bit Linux.

Input C/C++ Header

struct ec_sdo_request;
typedef struct ec_sdo_request ec_sdo_request_t;
int *ecrt_sdo_request_data(
        ec_sdo_request_t *req /**< SDO request. */
        );

Bindgen Invocation

$ bindgen input.h

Actual Results

#[repr(C)]
#[derive(Debug, Copy, Clone)]
pub struct ec_sdo_request {
    _unused: [u8; 0],
}
pub type ec_sdo_request_t = ec_sdo_request;
extern "C" {
    #[link_name = "_Z21ecrt_sdo_request_data"]
    pub fn ecrt_sdo_request_data(req: *mut ec_sdo_request_t)
     -> *mut ::std::os::raw::c_int;
}

Expected Results

#[repr(C)]
#[derive(Debug, Copy, Clone)]
pub struct ec_sdo_request {
    _unused: [u8; 0],
}
pub type ec_sdo_request_t = ec_sdo_request;
extern "C" {
    pub fn ecrt_sdo_request_data(req: *mut ec_sdo_request_t)
     -> *mut ::std::os::raw::c_int;
}

Which clang version is this?

This sounds like #528

[chengchangwu]

I've clang-3.8, clang-3.9 and and old libclang1-3.6 installed. After removing clang-3.8 and old libclang1-3.6, the problem is fixed.

Thanks.

Closed as a dupe of #528 then, thanks for checking!

There's a workaround explained there.
