Hi,

Are you using WIndows - Code Composer Studio or Linux?

Because optimization options vary as per the environment used.

Hi,

If you are using linux, then while compiling the projects using arm-gcc you can optimization levels as command line parameters. Is there any other specific behaviour that you have in mind, due to which you are modifying the .bld file?

Hi,

I am running the scale application . i have used opimization options like -o1 in config.bld and package.bld while compiling the server side.i profiled it and i am getting cycles as follows with -o1:

1863019

and with -o3

i am getting the cycles as :

1863543

can you tell me how i can specify these options correctly?

how do i know whether it is in release mode or debug mode?

Hi,

Turning on optimization flags makes the compiler attempt to improve the performance and/or code size at the expense of compilation time and possibly the ability to debug the program.

Hence, I think its valid enough to get more number of compile cycles when optimization is set to O3.

AS far as debug/ release mode is concerned, using the -odebug and -orelease option could help you select valid options.
