/**
* Bindings for symbols and defines in `mach-o/stab.h`
*
* This file gives definitions supplementing <nlist.h> for permanent symbol
* table entries of Mach-O files. Modified from the BSD definitions. The
* modifications from the original definitions were changing what the values of
* what was the n_other field (an unused field) which is now the n_sect field.
* These modifications are required to support symbols in an arbitrary number of
* sections not just the three sections (text, data and bss) in a BSD file.
* The values of the defined constants have NOT been changed.
*
* These must have one of the N_STAB bits on. The n_value fields are subject
* to relocation according to the value of their n_sect field. So for types
* that refer to things in sections the n_sect field must be filled in with the
* proper section ordinal. For types that are not to have their n_value field
* relocatated the n_sect field must be NO_SECT.
*
* This file was created based on the MacOSX 10.15 SDK.
