Alignement problems with SSE vector types

[Richard Guenther]

Hi!

I get SIGSEGVs due to misaligned memory operands for the
movaps instruction in both parameter passing and constant
loading. This is with mainline from about a week ago, I'm just
now checking current.

Is this a known problem? A very simple testcase looks like

typedef float Vector __attribute__((mode(V4SF)));

void printV(Vector x) {}

int main(int argc, char **argv)
{
        Vector x = { 1.0f, 2.0f, 3.0f, 4.0f };
	printV(x);
	printV(x);
	return 0;
}

note that the second call to printV is required, just calling
once works (just good luck, I think).

Richard.
