Access to enum definition at run time

Hi,

I apologize upfront if this email is outside the scope of this email listing.

I've recently wrote an article about "Automatic Enum Stringification
in C via Build-Time Code Generation"
(https://medium.com/@yair.lenga/automatic-enum-stringification-in-c-via-build-time-code-generation-659b67133125)

The short version is that it extracts enum definitions from the debug
(DWARF) section, and generates functions: enum labels->values, enum
value->enum, enum value iterators. There are no runtime dependencies
on DWARF. Sample Code:

enum country_code {  ISO3_AFG = 4, ... } ;

// This macro trigger including of enum metadata structures.
ENUM_DESCRIBE(country3, country_code)

char * country_label(enum country_code c){
   // Use the meta data to lookup matching label
   return ENUM_LABEL_OF(country3, c) ;
}

Current implementation relies on python tool (using pyelftools) to
extract the enum definition and generate C structures to support the
runtime lookup/enumerations.

As an experiment, I work on GCC plugin that will perform this
generation at compile time - injecting the data structures (mostly
name/value pairs) directly into the object file. I have a prototype
that works (most of the time ...). It is 'ugly', as this is my first
attempt to develop a GCC plugin.

Looking for any feedback about the
1, Idea/concept.
2. The implementation of the pugin (Github URL)
3. Is there a path for making it an experimental/official GCC
extension? (after cleanup, reviews, adding test cases/, etc.)

Thanks for you time!
