The problem isn't new:
[...@gnu-6 case3]$ cat x.c
#include "x.h"
void
foo (long double x, struct A y, long double z)
{
int i;
struct A a = { { 0, 1, 2, 3 } };
if (x != 8.0L || z != 8.0L)
__builtin_abort ();
if (__builtin_memcmp (&a, &y, sizeof (a)))
__builtin_abort ();
}
[...@gnu-6 case3]$ cat x.h
struct A
{
float V4SF __attribute__ ((vector_size (16)));
};
void foo (long double, struct A, long double);
[...@gnu-6 case3]$ cat main.c
#include "x.h"
int
main (void)
{
struct A a = { { 0, 1, 2, 3 } };
foo (8.0L, a, 8.0L);
return 0;
}
[...@gnu-6 case3]$ make CC=gcc
gcc -m32 -g -O -msse2 -c -o x.o x.c
gcc -m32 -g -O -mno-sse -c -o main.o main.c
