I’m using “.align 16 \n\t” in some inline ARM assembly that is implementing some loops
to align it on a 16 byte boundary however gcc asm compiler is complaining that alignement
is too large

    I think the .align directive for this particular CPU probably takes a power of 2 for the alignment argument, so to get 16 byte alignment you would need:

    .align 4

    Note that this directive behaves differently for different CPUs – see tigcc.ticalc.org/doc/gnuasm.html#SEC70
