Huh, how does glibc know about all possible past and future legacy code in the application?When dlopen() gets a legacy binary and the policy allows that, it will manage the bitmap: If a bitmap has not been created, create one. Set bits for the legacy code being loaded.
I was thinking about code that doesn't go through GLIBC like JITs.
