If it is a guaranteed behavior that GCC of all versions that support only get_symbols_v2 don't leave a temporary file behind if it is suddenly disrupted during get_symbols_v2 execution, then yes, mold can restart itself when get_symbols_v2 is called for the first time. Is this what you want? I'm fine with that approach if it is guaranteed to work by GCC developers.
