Re: [android-building] How to disable optimization when building AOSP?

[Colin Cross]

You can try changing the default flags for the architecture you are
about, for example
https://android.git.corp.google.com/platform/build/soong/+/master/cc/config/arm64_device.go#49,
but it is likley to cause build problems in a few modules.  For
example, ART sets strict stack frame size limits that will probably
fail with global -O0.

[android-building] How to disable optimization when building AOSP?

[Xie Wu]

Hi, I found some optimized variables when debugging so, such as libart.so.
I tried "mma LOCAL_CFLAGS="-O0 -g"", but it does not work. (reference: How 
to make debug build of specific module under AOSP tree? 

)
How can I disable optimization?
Thanks.
