> The beginning of the RW region contains pointers to c++ vtables which are > always located at a fixed offset from the shared base address at runtime. > This offset can be calculated at dumptime and stored with the read-only > tables at the top of the RO region. As a further improvement, all the > pointers to RO tables are replaced with offsets as well. > > These changes will reduce the number of pointers in the RW and RO regions and > will allow for the relocation bitmap size optimizations to be more effective. > Verified with tier 1-5 tests.
