[lldb-dev] LLDB support for python scripts in ELF section, like .debug_gdb_scripts in GDB

LLDB has a similar feature, except:

a) it tries to load python scripts from dSYM bundles. If you have debug info stored in foo.dSYM, it will look for foo.dSYM/Contents/Resources/Python/foo.py
As far as I know, dSYMs only exist on Apple systems, so clearly you would need to design something else to load from places other than such debug info bundles

b) the feature is off by default, but there's a setting you can tweak to enable it. That is due to security concerns
I have given some thought to ideas in that space (e.g. code-signatures for the script files) but no code exists to back those thoughts
