Mark debug sections referenced by kept debug sections If a debug section is referenced by a kept debug section, it should also be kept. Some targets, like mips, keep input files when there are some special sections, like .gnu.attributes, even if input file is unused otherwise. In this case, all debug sections are kept. The new test will fail on such targets. We can either fix those targets or XFAIL the test. bfd/ PR ld/20882 * elflink.c (elf_gc_mark_debug_section): New function.

pr20882 testcase -gdwarf-sections doesn't work on targets that lack support to emit address size relative relocs. The testcase as it was avoided -gdwarf-sections doing anything by providing a non-empty .debug_line. It's better to not use -gdwarf-sections. Also, the testcase failed to match the output for 16-bit address targets like avr. PR ld/20882 * testsuite/ld-gc/pr20882.d: Don't pass -gdwarf-sections to gas. Allow for 16-bit address targets and match expected data fully. * testsuite/ld-gc/pr20882a.s: Delete .debug_line section. * testsuite/ld-gc/pr20882b.s: Likewise. * testsuite/ld-gc/pr20882c.s: Likewise. 2017-05-18 06:58:17 +02:00			`.globl main`
