Natural alignment used on NetBSD/m68k

[John Paul Adrian Glaubitz <glaubitz%physik.fu-berlin.de@localhost>]

Hello,

can anyone tell me whether NetBSD/m68k uses a natural alignment of two or four bytes?
I'm asking since Linux/m68k defaults to two bytes alignment which has started to become
a burden as more and more programs require at least four bytes alignment these days.
Software that is affected includes CPython, LLVM, Mold, gccgo and many more.

As Debian's m68k maintainer, I have been trying to convince the community to switch to
four bytes alignment, but so far an agreement has not been made. On the other hand, the
original SysV Unix ABI released by Motorola [1] defaults to four bytes alignment.

And maybe someone could compile and run the following code on a NetBSD/m68k instance to
confirm the alignment to be four bytes:

#include <stdio.h>

typedef struct { char x; int y; } test_t;

int main(void)
{
    printf("%d\n", sizeof(test_t) / 2);
}

Thanks,
Adrian
