PR gold/21066 * gc.h (gc_process_relocs): Track relocations in .eh_frame sections when ICF is enabled, even though the .eh_frame sections themselves are not foldable. * icf.cc (get_section_contents): Change arguments to permit operation on just part of a section. Include extra identity regions in the referring section's contents recursively. (match_sections): Lock object here instead of in get_section_contents so that get_section_contents can operate recursively. (Icf::add_ehframe_links): New method. (Icf::find_identical_sections): Pass .eh_frame sections to add_ehframe_links(). Increase default iteration count from 2 to 3 because handling exception info typically requires one extra iteration. * icf.h (Icf::extra_identity_list_): New data member with accessor. (is_section_foldable_candidate): Include .gcc_except_table sections. * options.h: Update documentation for new default ICF iteration count. * testsuite/Makefile.am (icf_test_pr21066): New test case. * testsuite/Makefile.in: Regenerate. * testsuite/icf_test_pr21066.cc: New source file. * testsuite/icf_test_pr21066.sh: New test script.
