Copy relocations against protected symbols
Copy relocs are used in a scheme to avoid dynamic text relocations in non-PIC executables that refer to variables defined in shared libraries. The idea is to have the linker define any such variable in the executable, with a copy reloc copying the initial value, then have both the executable and shared library refer to the executable copy. If the shared library defines the variable as protected then we have two copies of the variable being used. PR 15228 * elflink.c (_bfd_elf_adjust_dynamic_copy): Add "info" param.

or1k: Do not override section for non-TLS symbols.
Outgoing section for relocations was computed by setting a shared pointer to which section should be used. For TLS this was overriden to use .rela.got since they use GOT entries but since the pointer is per section that whole section was relocated to .rela.got, even non-TLS relocations. * elf32-or1k.c: Fix a bug where non-TLS relocations would be forced into .rela.got if it contained TLS relocations as well. |
