What you have described is not my experience. I have updated my file locally and restarted the Arduino IDE 2.x, and you can see the results below:

I chose six random files from my compile logs, and you can clearly see they are compiling with only -Og.

The change does not do both -Os and -Og. It only includes the one indicated by the menu options set in the Arduino IDE 2.x. For example, in the case above, I have selected Sketch > Optimize for Debugging.

I'm am working with the Portenta H7, and it is working perfectly. It sounds like the GIGA configuration has a bug.

[per1234]

Look closely at the commands you shared. You can see the option file argument right here in the command, after the -Og flag:

@/home/zak/.arduino15/packages/arduino/hardware/mbed_portenta/4.1.1/variants/PORTENTA_H7_M7/cflags.txt

Note that option file contains an -Os flag:

https://github.com/arduino/ArduinoCore-mbed/blob/d63f3ab813c634697165cca39b9b3aff01cb59df/variants/PORTENTA_H7_M7/cflags.txt#L14

https://gcc.gnu.org/onlinedocs/gcc/Overall-Options.html#:~:text=some%20other%20language.-,%40file,-Read%20command%2Dline

@file Read command-line options from file. The options read are inserted in place of the original @file option.

[zfields]

Ahh... I see.

Okay, so the answer then is to remove -Os from the cflags.txt file, right?

I'm happy to add that to the PR.

It also looks like -Wall and -Wextra should be removed as well.

[facchinm]

Hi @zfields , removing entries from *flags.txt is not trivial since they are autogenerated when running mbed-os-to-arduino script. I think the most sensible approach would be to understand which flag gets accepted by gcc (the first it encounters, the last ? ) and add the -Os entry there

[per1234]

understand which flag gets accepted by gcc (the first it encounters, the last ? ) and add the -Os entry there

It is the last:

https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#:~:text=If%20you%20use%20multiple%20%2DO%20options%2C%20with%20or%20without%20level%20numbers%2C%20the%20last%20such%20option%20is%20the%20one%20that%20is%20effective.

If you use multiple -O options, with or without level numbers, the last such option is the one that is effective.

So -Og [...] -Os is equivalent to -Os and -Os [...] -Og is equivalent to -Og.

Updated to follow suggestion. :+1:
