AM2732: Per function optimization setting

Ken Zhang

Part Number: AM2732

Hi Experts

Customer would like to adjust the optimization of a certain function， so that they can insert a break point as they will,

They found that below cmd can not be recognized by arm compiler, What's the right pragma for AM2732 SDK?

So am273x/main_mss.c:168:9: error: unknown pragma ignored [-Werror,-Wunknown-pragmas]
#pragma FUNCTION_OPTIONS ( funcName, "--opt_level=0" );

Thanks

Hi Ken,

Since this question is TI CLANG compiler related, I will forward it to our compiler team for further help.

Best regards,

Ming

Unfortunately, tiarmclang does not support the FUNCTION_OPTIONS pragma, and there is no equivalent. The closest solution is to isolate that function into its own file, then lower the optimization level for that file. If you build your code with Code Composer Studio, you could use File Specific Options.

Thanks and regards,
