Release Build and Debug Symbols

[kostyan5]

Why does Release build elf still contain .debug_* symbols?

Debug symbols in the elf file do not affect the size or the speed of an application once it had been uploaded. So there is no downside in keeping the debug symbols. They do allow for readable stack traces, if anything.

If you need the elf file to be stripped, you can easily do this in project makefile.

I don't particularly care about elf file. I was just curious. What's the parameter to strip debug symbols from elf?
