Re: [PATCH] Fix fc-prototypes usage with C_INT64_T and non LP64 Targets.

[Thomas Koenig via Gcc-patches]

Hi Steve,

Hi Andrew,

"long long". This was just an oversight and a missing check.

Committed as obvious after a bootstrap/test on x86_64-linux-gnu.

Thanks!

I think this one is obvious enough that it deserves a backport.
I've cherry-picked this for gcc12, will do gcc11 tomorrow.

The patch is incomplete.

module foo
  use, intrinsic :: iso_c_binding
  implicit none
  public :: bar
  type, bind(c) :: bar
   real(10) a
  end type
end module

This yields

typedef struct bar {
long_double a /* WARNING: Converting 'REAL(10)' to interoperable type */;
} bar;

That should be 'long double'.

Fixed as obvious in 69044e11ac5 .

I will backport soon.

Thanks for the heads-up!

Best regards

        Thomas
