The program
--
#include <linux/time.h>
void foo(struct timespec *t, struct timespec *u)
{
struct timespec zero = {0, 0};
*t = zero;
*u = zero;
}
--
produces the following code on i386 with -Os
--
.file "b.c"
.text
.globl foo
.type foo, @function
foo:
pushl %ebp
movl %esp, %ebp
movl 8(%ebp), %eax
movl $0, (%eax)
movl $0, 4(%eax)
movl 12(%ebp), %eax
movl $0, (%eax)
movl $0, 4(%eax)
leave
ret
.size foo, .-foo
.ident "GCC: (GNU) 3.3.1 20030626 (Debian prerelease)"

It would be much better size-wise if it stored a zero in a register
and then stored the register into those locations.
