--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
6.3.0 produced:

        sub     r1, r4, #16
        ldr     r4, [r4, #-4]
        ldr     r0, .L3+4
        ldm     r1, {r1, r2, r3}

5.4.0 produced:

        sub     r1, r4, #16
        ldr     r4, [r4, #-4]
        ldr     r0, .L3+4
        ldmia   r1, {r1, r2, r3}

7.40 produced:

        ldrd    r2, r3, [r4, #-12]
        ldr     r1, [r4, #-16]
        ldrd    r4, r5, [r4, #-4]
        ldr     r0, .L4+4
        strd    r4, r5, [sp]

Which was changed by r7-4653-g2fe3721128b991 or r7-991-g37923729c5ab01 .

The ldrd support was added originally with r0-122648-g4542a38a21fea5 (for G=
CC
4.9.0).

So closing as fixed.=
