Subject: Remove an unnecessary block in call_function_by_hand_dummy
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b4b08fa2aa25f245c77921ad2405c15d30e421ed;p=binutils-gdb.git

Remove an unnecessary block in call_function_by_hand_dummy

I noticed that call_function_by_hand_dummy has a block that only
exists to declare a variable, like:

    {
      int i;
      for (i = ...0)
	...
    }

This patch removes the unnecessary and the extra indentation by moving
the declaration into the "for".
