ValueError: invalid literal for int() with base 10: '"loop alignment."'

the gcc/params.def file is:
DEFPARAM (PARAM_ALIGN_LOOP_ITERATIONS,
          "align-loop-iterations",
          "Loops iterating at least selected number of iterations will get "
          "loop alignment.", 4, 0, 0)

The index is used during the for loop, so extra strings cannot be ignored.
We solve this problem by filtering out the string before the for loop.
