Could TI compiler arm_5.1.7 just optimize a part of code?

Brian Hsiao

We want to use it on StarterWare with CCS 5.5.0.

Because optimize usually make code run incorrect, we don’t want to optimize too many sectors.

Could the TI compiler arm_5.1.7 do it?

Hello Brian,

You can build you code in debug mode with -g option to avoid optimizations. By default for debug mode optimizations are off (--opt-level=off).

You can read more about this in section Invoking Optimization of www.ti.com/.../spnu151m.pdf

Hello Prasad,

We want to optimize just a function or a part of function, rather then all file.

Could CCS do that?

thanks

Brian,

Since this is a compiler question, I went ahead and moved it over to the compiler forum.

You can control the level of optimization applied to one function with the FUNCTION_OPTIONS pragma. Please read about it in the ARM compiler manual.

Thanks and regards,
