return file and line number information. The nm utility supports -l for using debug information to obtain file and line information for each symbol, if available. We have a tool that consumes this information and displays it. This identified a problem with the 'nm' utility. When a source is compiled with -O2, functions can be inlined. The compiler also produces an uninlined copy of the function, normally for linking to other object files. In the case of DWARF2 debug information, the compiler generates debug information to describe a function. If that function is inlined, the compiler then references that debug information from the inlined and uninlined copies of the routine through the use of the DW_AT_abstract_origin reference. When nm is used on such a file, it is not able to find file and line information because that information is present in the common debug information and not at each actual implementation of the function. The 'nm' utility only retrieves the name of the function from the abstract origin debug information and no more. What I am proposing is to modify the find_abstract_instance_name() function (which I renamed to find_abstract_instance() ) to return the name of the function as well as any file and line information. The routine is already parsing all of the debug information in the abstract instance, so it is easy to pick up the file and line information at that time. If, for some reason, the file and line information is not present, the routine behaves as before. For example, if I have a simple test case: int foo(int j) { if (j < 15) j += j << 2; else j += j << 6; return j; } int main (int argc,char **argv) { int i = argc; i += foo(i); return i; } If that test case is compiled with -O2 and then 'nm -l' reads that executable, it currently produces this symbol output (ignoring a lot of library symbols): 8048400 T foo 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 If I modify 'nm' to return file and line information for abstract instances, it produces the following output: 08048400 T foo /scratch/pcarroll/its254/test/mytest.c:1 080482e0 T main /scratch/pcarroll/its254/test/mytest.c:12 -------------------------------------------------------------------------- bfd * bfd/dwarf2.c (find_abstract_name): Modified to return file and line information in addition to name, if they can be found.

The PR22200 fuzzer testcase found one way to put NULLs into .debug_line file tables. PR22205 finds another. This patch gives up on trying to prevent NULL files in the file table and instead just copes with them. Arguably, this is better than giving up and showing no info from .debug_line. I've also fixed a case where the fairly recent DWARF5 support in handling broken DWARG could result in uninitialized memory reads, and made a small tidy.

2017-02-16bfd: Improve lookup of file / line information for errorsAndrew Burgess1-0/+32
When looking up file and line information (used from the linker to report error messages) if no symbol is passed in, then use the symbol list to look for a matching symbol. If a matching symbol is found then use this to look up the file / line information. This should improve errors when looking up file / line information for data sections. Hopefully we should find a matching data symbol, which should, in turn (we hope) match a DW_TAG_variable in the DWARF, this should allow us to give accurate file / line errors for data symbols. As the hope is to find a matching DW_TAG_variable in the DWARF then we ignore section symbols, and prefer global symbols to locals. bfd/ChangeLog: * dwarf2.c (_bfd_dwarf2_find_nearest_line): Perform symbol lookup before trying to fine matching file and line information. ld/ChangeLog: * testsuite/ld-elf/shared.exp: Update expected results. * testsuite/ld-elf/dwarf2.err: Likewise
2017-02-16bfd/dwarf: Improve use of previously loaded dwarf informationAndrew Burgess1-2/+21
When parsing DWARF data in order to report file/line type error messages we perform section placement to make section addresses unique within relocatable object files. Currently, if we reuse previously loaded (and cached) dwarf data then we neglect to perform section placement, the result is that the section addresses will not be unique, and we might, incorrectly associate an address with the wrong debug information, and so report an incorrect file and line number. Further we neglect to check that that bfd for which we are looking up debug information is actually the bfd for which the previous debug information was loaded, it is possible that we will reuse previously loaded debug information for a different bfd. And finally, due to following of gnu_debuglink links in one bfd to another, the process of checking that the cached debug information is valid requires us to track the original bfd in the cached debug information. The original debug information here is either the bfd that we're interested in, not the bfd we finally load the debug information from. bfd/ChangeLog: * dwarf2.c (struct dwarf2_debug): Add orig_bfd member. (_bfd_dwarf2_slurp_debug_info): If stashed debug information does not match current bfd, then reload debug information. Record bfd we're loading debug info for in the stash. If we have debug informatin in the cache then perform section placement before returning. ld/ChangeLog: * testsuite/ld-elf/dwarf.exp (build_tests): Add new tests. * testsuite/ld-elf/dwarf2.err: New file. * testsuite/ld-elf/dwarf2a.c: New file. * testsuite/ld-elf/dwarf2b.c: New file. * testsuite/ld-elf/dwarf3.c: New file. * testsuite/ld-elf/dwarf3.err: New file.

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. PR binutils/19315 * dwarf2.c (_bfd_elf_find_function): Return symbol matched.
