[PATCH] AAPCS-VFP: double and long double have the same machine type

[Oliver Stannard]

Hi all,

In the AAPCS, for the purposes of deciding if a struct is a homogeneous
floating-point aggregate, two fundamental types are considered the same if
their machine types are the same. The `double' and `long double' C types
have the same machine type in the 32-bit version of the ABI, so we must
consider the following struct to be a HFA:

struct {
  double a;
  long double b;
} s;

The attached patch fixes this.

Oliver
