I split this into smaller pieces to make it less of a chore to review, but I'm also happy to squash these into larger patches if you prefer. How would you like to see this split instead? > For example, 02/19 adds malloc(). > > 03/19 immediately replaces it with calloc(). > > Then, I wonder why you did not add calloc() in the first place. Yes, that wasn't ideal, but like I said in my other response, I tried to keep the churn minimal.

Unfortunately this is not the case for Rust object files where exports are handled separately. Passing the list of symbols as input feels more flexible to me, and also is rather convenient for debugging. > > - Added a --symtypes flag for generating a genksyms-style > > symtypes output based on Petr's feedback, and refactored > > symbol version calculations to be based on symtypes instead > > of raw --dump-dies output. > > > > I do not know if this is worthwhile. Greg, Petr, do you want to comment on the usefulness of the symtypes output?

Ah, this obviously needs to depends on the .o files instead. I'll sort this out in v3. Thanks for taking a look! Sami
