  46 # whitespaces in ARM register specifications such as [ r1, #12 ] or [
  47 # r2 ] cause the assembler to reject the code. Since there are
  48 # numerous instances of such cases in the code, we use sed rather than
  49 # a patch. We simply replace [ foobar ] by [foobar] to work around the
  50 # problem.
