Suggestion: Add a check after generating random code in 'src/randomcode.py'

[lawyer61]

Sometimes the csmith will generate a code without 'main' function (This may because of too many args ). When this happens, delay*.o will not have a 'slp' symbol and bring failure when linking it with test.o

change the function ch_main_arg to this:

def ch_main_arg(pn, argname, funcname):  
  # change main function name with random_string name 
  modify_flag = 0
  for line in fileinput.input(pn, inplace=True):
    if "int main" in line:
      line = line.replace("void", "%s" % argname)
      line = line.replace("main", "%s" % funcname)
      modify_flag = 1
    if "int print_hash_value = 0;" in line:
      #line = line.replace("0", "1")
      continue
    if "print_hash_value" in line:
      continue

    sys.stdout.write(line)
  
  return modify_flag

and change line 116 to :

      if not ch_main_arg(var[1], argname, funcname):
        continue

That works for me when fail running python randomcode.py for the first time. Hope it helps.
