2015-12-02addr2line vs. inlined C functions called from C++Alan Modra1-13/+22
In this case the inlined function doesn't have DW_AT_linkage_name in .debug_info, but the language is C++ so find_nearest_line goes looking in the symbol table. Since the function is inlined the enclosing non-inline function symbol is returned from _bfd_elf_find_function, which is wrong. This patch only uses a symbol if its address matches.

2014-12-10Don't return DW_AT_name for function name in C++Alan Modra1-32/+196
DW_AT_name for functions typically just contains the base function name, so lacks namespace, class and parameter information. It would be possible to extract all these from the DWARF, but at a considerable complication of the parser in dwarf2.c, and then you'd need to mangle it all together. Much simpler is to look up the actual symbol. This patch does that, avoiding the extra symbol lookup when the language doesn't do name mangling. PR 17541 * dwarf2.c (struct comp_unit): Add "lang".

2014-04-24PR16867, linking object with separate debug fileAlan Modra1-135/+171
This teaches the DWARF2 find_line functions how to deal with separate debug relocatable object files. Also fixes a major bug: When _bfd_dwarf2_slurp_debug_info was split out, place_sections ran after .debug_info was relocated. This defeated the whole purpose of place_sections. See the comment I added before place_sections. Fixes some minor bugs too: - place_sections didn't set VMA for alloc but non-load sections (bss). - zero size sections can have symbols, so they need their VMA set too. - last_vma was incorrectly adjusted. - my last change to place_sections left VMA unchanged for .debug_info when the linker has mapped input to output sections, but this is wrong since bfd_simple_get_relocated_section_contents unmaps debug sections.

2014-04-23PR ld/16787, stale dwarf2 stashAlan Modra1-7/+78
Throw away the dwarf2 stash if it becomes invalid due to section VMAs changing. It would be nice to reclaim all the bfd_alloc memory here when we throw away the stash, perhaps by putting everything we alloc on a private dwarf2 objalloc, but I haven't done that with this patch. I've also fixed a problem with bfd_perform_relocation losing reloc addends, which meant a second or subsequent look at debug info sections did not properly relocate the sections. I can't see why bfd_perform_relocation should need to change addends except for ld -r, and the history (985fca12, e98e6ec1) doesn't help much. Finally, the patch tweaks place_sections to avoid unnecessary work. If we've mapped input to output sections, then input section VMA isn't used so there's not much point in adjusting it. Incidentally, this also means place_sections isn't effective in all cases. PR ld/16787 * dwarf2.c (struct dwarf2_debug): Add sec_vma field. (place_sections): Do not modify VMA of sections when called from linker after sections have been placed in output sections. Short circuit single section case.
