For code size, it will be profitable everywhere. On ARM, aggressive use of post-increment is an important code-size optimization and we are not presently doing a very good job taking advantage. So, whatever solution we settle on should not be dependent on being in a loop. -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] (650) 331-3385 x713
