Segger Embedded Studio Optimization for Release

[Jong yoon lee]

Hello,

 I was wondering if there are any article or tutorial I can follow to optimize code build with Segger Embedded Studio.

I was able to follow this article(https://devzone.nordicsemi.com/b/blog/posts/getting-more-out-of-make) to configure my GCC/Makefile setup. I want to know where I need to modify to get the same optimization. There are a lot of options and a bit confusing in ses.

Also, are the only three flags I can play around with 'O3', 'G3' and `flto`?

Best,

Jong

Segger Embedded Studio just uses the standard GCC compiler

I know that it will use GCC as the default compiler.

The question was specifically asking which option I need to modify in the embedded studio option setting.

Though it will help others as well.

Greetings,

If they are link options, can they be added using the following command:

awneil might be getting at the fact that not that long ago gcc would generate unstable code at -O3 and beyond. Are you confident it'll emit production quality code for you at O3?  I'm not brave enough for more than O2 but that's just me.  YMMV

Thanks you so much :)

This is interesting
What kind of behaviour did you see?

I am particularly interested in generating the lower power application code.

Where do I add the flto optimization flag?

I would recommend not using that flag. See this and this post.
