Daniel,

the assembly I get out of gcc mainline (arm-elf targeted cross compiler) doesn't seem to be what 
you initially reported. Can you confirm whether the below code is correct? Thanks,

Dara

        .file   "test.c"
        .text
        .align  2
        .global main
        .type   main, %function
main:
        @ args = 0, pretend = 0, frame = 64
        @ frame_needed = 1, uses_anonymous_args = 0
        mov     ip, sp
        stmfd   sp!, {fp, ip, lr, pc}
        sub     fp, ip, #4
        sub     sp, sp, #64
        mov     r1, #0
        sub     r3, fp, #12
        mov     r2, #15
.L5:
        subs    r2, r2, #1
        str     r1, [r3, #-64]
        add     r3, r3, #4
        bpl     .L5
        mov     r2, #2
        sub     r1, fp, #76
        mov     r0, #1
        mov     ip, r2

        cmp     r0, #0
