Pardon my confusion ...

AFAIU, before init_array was implemented, the .ctors *were* executed in
C B A order (by the loader).

Are you saying that you've re-ordered the link command line after init_array
became available?

Or that you kept the link command fixed, but switching to init_array gave
you significant speed up, which you don't want to lose?
