Compiler/TMS320C6713: Optimization Options

Nusrettin Gulec

Part Number: TMS320C6713

Tool/software: TI C/C++ Compiler

Hi all,

I need to specify the optimization only for certain files while I wish to leave the rest unoptimized. Does anyone have an idea about the options I should specify in the makefile so that I can apply -o2 only on two files such as File1.c and File2.c. I know that I can do this in CCS IDE by playing with the build options of these files only; yet I need to do this through the makefile rather than through the IDE.

In detail, I generate an application for C6713 using MATLAB/Simulink r2015b and using "Texas Instruments Code Composer Studio v5 (makefile generation only)" as the IDE/Toolchain. I can manually enter so-called "Compiler options string" to be copied to the makefile so that the output is generated accordingly. I was able to specify -o2 by inputting "opt_level=2" at that part for the whole project so that optimization is carried out for all files in the project.

Thanks for your help in advance.

    I presume this means your makefile is automatically generated by MATLAB.  None of us compiler experts are familiar with MATLAB, or this feature.  Perhaps there is a way to ask MathWorks your question.

    Thanks and regards,

    Hi George and Brian,

    Thanks for your directions; I will be trying to connect Mathworks on the issue indeed.

    However, I believe I misguided you guys by my first paragraph (completely my fault when I read it now). The thing I am trying to learn here, I believe, is not related to MATLAB. If not, I will be waiting for Mathworks to respond anyway. Thanks for your patience in reading the sequel.

    I'll try to put it as simple as possible: I do have a makefile that contains the line:

    COMPILER_CODEGEN_ARGS := -I"C:/Program Files/MATLAB/R2015b/toolbox/idelink/extensions/ticcs/inc" -I"C:/Users/sst ism/Documents/MATLAB/c6713/Nusret_6713_ticcs" -I"C:/Users/sst ism/Documents/MATLAB/c6713" -I"C:/Program Files/MATLAB/R2015b/extern/include" -I"C:/Program Files/MATLAB/R2015b/simulink/include" -I"C:/Program Files/MATLAB/R2015b/rtw/c/src" -I"C:/Program Files/MATLAB/R2015b/rtw/c/src/ext_mode/common" -I"C:/Program Files/MATLAB/R2015b/rtw/c/ert" --opt_level=2 -D"CHIP_6713" -D"__TICCSC__" -D"RT" -D"USE_RTMODEL" -mv6710 -D"MODEL=Nusret_6713" -D"NUMST=1" -D"NCSTATES=0" -D"HAVESTDIO=" -D"ONESTEPFCN=1" -D"TERMFCN=1" -D"MAT_FILE=0" -D"MULTI_INSTANCE_CODE=0" -D"INTEGER_CODE=0" -D"MT=0" -D"CLASSIC_INTERFACE=0" -D"ALLOCATIONFCN=0" -D"TID01EQ=0"

    where the stressed part triggers optimization level 2 during compilation (at least to my understanding). I wonder how I should be editing this part so that compiler optimization is enabled only for a single file; say MyFile.c (if that's possible by any means).

    Thank you for your help.

    This question is about make, and not the TI compiler.  As such, you are in the wrong forum.  I'll make a few general comments that may help.

    One approach that comes to mind  ... Create another make variable, say OPT_ARGS.  OPTS_ARGS is different based on what file is being compiled.  Wherever the present $(COMPILER_CODEGEN_ARGS) appears, $(OPT_ARGS) needs to appear as well.  For more help with this, please consult your favorite book or website about make.

    Thanks and regards,

    -George

    Hello George,

    Sorry for the lack of discrimination between make and TI compiler on my side; I am too novice about the issues as I pointed out.

    Thanks for your directions once again. I will try to go on with OPT_ARGS and try to resolve my issue elsewhere beyond this point.

    Regards,
