Complement commitb531344c34("PR ld/20828: Reorder the symbol sweep stage of section GC") and commit81ff47b3a5("PR ld/20828: Fix linker script symbols wrongly forced local with section GC") and move symbol version processing ahead of the symbol sweep stage of section GC, all in `bfd_elf_size_dynamic_sections', so that version symbols created stay in the global scope and are not output as local symbols to the dynamic symbol table in the presence of corresponding symbol definitions pulled from a DSO involved in a link. Consolidate the whole of symbol version processing into a single block from all parts scattered across the function and rearranging the local variables used as necessary, however leaving the setting of dynamic entries associated with the DT_VERDEF, DT_VERDEFNUM, DT_VERNEED and DT_VERNEEDNUM tags and the SEC_EXCLUDE flag for unused `.gnu.version' section in the original places. With the rearrangement of code blocks `Elf_Internal_Verneed *t' would shadow the previous definition of `struct bfd_elf_version_tree *t', so rename the former variable to `vn'. bfd/ PR ld/20828 * elflink.c (bfd_elf_size_dynamic_sections): Move symbol version processing ahead of the call to `elf_gc_sweep_symbol'. ld/ PR ld/20828 * testsuite/ld-elf/pr20828-d.sd: New test. * testsuite/ld-elf/pr20828-e.sd: New test. * testsuite/ld-elf/pr20828-v.od: New test. * testsuite/ld-elf/pr20828-v.ver: New test version script. * testsuite/ld-elf/pr20828-v.ld: New test linker script. * testsuite/ld-elf/pr20828.ld: Add `.gnu.version' and `.gnu.version_d'. * testsuite/ld-elf/shared.exp: Run the new tests.
