[cfe-dev] Advice for fixing some misguided code

[Martin J. O'Riordan via cfe-dev]

Thanks David, I will see if I can rework this using your suggestion.  I just "know" there has to be a better way than what I am doing now :-)

All the best,

The best mechanism would be module-level metadata.  There’s already a creator node used for emitting DWARF debug info, so extending that to include the complete clang invocation seems like the best bet.
