Garbage collecting debug sections I noticed that _bfd_elf_gc_mark_extra_sections attempts to unmark related debug sections when it finds an unmarked code section. When it finds .text.foo is unmarked, for example, it removes .debug_line.text.foo as well (using the section name as a suffix match check. However, it bails out after finding one such section. bfd/ * elflink.c (_bfd_elf_gc_mark_extra_sections): Don't break on first matching debug section. ld/testsuite/ * ld-gc/all-debug-sections.d: New file. * ld-gc/all-debug-sections.s: Likewise. * ld-gc/gc.exp: Execute new testcase. 2015-03-24 21:48:04 +08:00			`#name: --gc-sections with multiple debug sections for a function section`

Remove run_dump_test support for objcopy as a dump program We have three copies of run_dump_test in the testsuite. This is a first step towards consolidating them. A few tests use objcopy to convert to verilog or srec output, then check that output is as expected. Those tests can just as easily use objdump, keeping the set of dump programs (addr2line, nm, objdump, readelf, size) separate from utilities under test. That in turn makes auto-detecting the dump program possible in more places. binutils/ * testsuite/binutils-all/group-7a.d, * testsuite/binutils-all/group-7b.d, * testsuite/binutils-all/group-7c.d, * testsuite/binutils-all/symbols-1.d, * testsuite/binutils-all/symbols-2.d, * testsuite/binutils-all/symbols-3.d, * testsuite/binutils-all/symbols-4.d: Remove DUMPPROG. gas/ * testsuite/gas/mri/char.d: Don't objcopy to srec, objdump instead. * testsuite/gas/mri/float.d: Likewise. * testsuite/lib/gas-defs.exp (run_dump_test): Remove support for objcopy as a dump tool. ld/ * testsuite/ld-elf/interleave-0.d, * testsuite/ld-elf/interleave-4.d: Don't objcopy to srec, objdump instead. * testsuite/ld-gc/all-debug-sections.d, * testsuite/ld-scripts/provide-4.d, * testsuite/ld-scripts/provide-5.d, * testsuite/ld-scripts/provide-6.d, * testsuite/ld-scripts/provide-7.d, * testsuite/ld-scripts/provide-8.d, * testsuite/ld-scripts/segment-start.d: Remove PROG, specify nm instead. * testsuite/lib/ld-lib.exp (run_dump_test): Remove support for objcopy as a dump tool. 2018-09-13 13:13:34 +08:00			`#nm: -B`
