Hi,

In the ARM ABI documentation I come across functions defined like:

__value_in_regs struct bar foo(int a, int b) {
    ...
}

but GCC(4.3.3) doesn't allow it and all I could find are references to some RealView compiler. Is there any way of doing this from GCC?

I have tried -freg-struct-return but it doesn't make a difference. As it is an ABI I can't change the original programs, and returning a regular struct mangles the stack.

I would rather not using assembly for this if avoidable as it isn't otherwise necessary.

Thanks!
