Re: [PATCH 1/4] Clean up of new format of -falign-FOO.

Hi Martin,

Your alignment patch breaks the arm port. In the file arm.c, function 
'get_label_padding' the code uses:

static HOST_WIDE_INT
get_label_padding (rtx label)
{
  HOST_WIDE_INT align, min_insn_size;

  align = 1 << label_to_alignment (label);
  min_insn_size = TARGET_THUMB ? 2 : 4;
  return align > min_insn_size ? align - min_insn_size : 0;
}

Which breaks with your current change. I think this needs to be modified to:

'align = 1 << label_to_alignment (label).levels[0].log'
