    On CCS 5.1, if i change optimization level of one source file more than one times, optimization level of other source files will be changed either, which is not what i expect.

    Anyone can help me?

    Thanks in advance.

      Hi Xiaojun,

      could you please send a test case where you see this?  More detailed information on what you are experiencing here?   I just tried in the latest 5.1.1 version of CCS and could not reproduce this.  I changed the optimization level of a file 3 times by right-clicking on the .c file and changing the setting and only this file changed.  It did not change other files in my case.  I tried 2 different workspaces and projects.

      Best Regards,

      Lisa

      Hi Lisa,

      I use 5.1.1.00031 version of CCS.

      Just now i made a simple CCS project for generic C64xx device using empty template. There are 2 files in the project, main.c and test1.cpp

      First change main.c to -O3, press OK, then change back to null, press OK.

      Change test1.cpp to -O3, press OK. Now, you can find level of main.c is -O3.

      Hereafter, if u change level of any one of this two files, level of another one will be changed by the bug.

      2642.testOp1.rar

      Best Regards,

      Xiaojun Wang

      Hi Xiaojun,

      I was able to reproduce this and filed a bug.  The ID is SDSCM00043779 and you should be able to track it here:

      https://cqweb.ext.ti.com/cqweb/main?command=GenerateMainFrame&service=CQ&schema=SDO-Web&contextid=SDOWP&username=readonly&password=readonly

      Thanks for the feedback.  I have also put your other question as a new post as it is unrelated to this specific bug/issue. 

      Best Regards,
      Lisa
