"""
Simple NM parsing of an object file
Given an object file, we call nm -aS file
Next, we parse stdout and match symbol lines corresponding to types
from nm_option_desc_map.
Data are aggregated into a dict using the keys from nm_option_desc_map
The keys are obtained from nm_option_desc_map and enforced inside the regex used
See nm_re_type_expr, nm_re_str, and nm_re in the static fields of this class
