When this sample is compiled with -O2 -m4 -S:

typedef int v4sf __attribute__ ((mode(V4SF)));
v4sf test2 (v4sf a)

{
        return a;
}

GCC assumes the floating-point vectors arrive in integer registers, which is
very silly. It should pass/expect them in floating-point registers.

test2:
        mov.l   r8,@-r15
        mov     r4,r0
        mov.l   r9,@-r15
        mov     r5,r1
        mov.l   r10,@-r15
        mov     r6,r2
        mov.l   r14,@-r15
        sts.l   pr,@-r15
        add     #-16,r15
        mov     r15,r14
        mov.l   r7,@(12,r14)
        mov.l   @(12,r14),r10
        mov.l   r4,@r14
        mov.l   r5,@(4,r14)
        mov     r10,r3
        mov.l   r6,@(8,r14)
        add     #16,r14
        mov     r14,r15
        lds.l   @r15+,pr
        mov.l   @r15+,r14
        mov.l   @r15+,r10
        mov.l   @r15+,r9
        rts
        mov.l   @r15+,r8

This is an ABI issue.
