bfd/dwarf: Improve use of previously loaded dwarf information
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.

PR ld/20828: Fix linker script symbols wrongly forced local with section GC
Fix a generic ELF linker regression introduced with a chain of changes
made to unused input section garbage collection:
- commit 1a766c6843ce ("Also hide symbols without PLT nor GOT
references."),
<https://sourceware.org/ml/binutils/2011-09/msg00076.html>,
- commit 1d5316ab67e1 ("PR ld/13177: garbage collector retains zombie
references to external libraries"),
<https://sourceware.org/ml/binutils/2011-10/msg00161.html>,
- commit 6673f753c019 ("Fix PR 12772, garbage collection of dynamic
syms"), <https://sourceware.org/ml/binutils/2011-12/msg00077.html>,
causing the garbage collection of unused symbols present in a DSO
involved in a link to make identically named symbols ordinarily defined
(i.e. not hidden or PROVIDEd) by a linker script local, even though the
latter symbols are supposed to be global as if no DSO defined them as
well.
This is because linker script assignments are processed very late as
`lang_process' proceeds, down in the call to `ldemul_before_allocation',
which is made after the call to `lang_gc_sections' to do input section
garbage collecting. Consequently if unused, then any such DSO-defined
symbol has already been garbage-collected and internally marked local.
It would ordinarily be removed from dynamic symbol table output, however
a linker script assignment correctly replaces its original definition
with the new one and enters it into the dynamic symbol table produced as
it is supposed to be exported. The original local marking is however
retained making the symbol local in the dynamic symbol table and
therefore not available externally. This also causes a sorting problem
with the MIPS target, which does not expect non-section local dynamic
symbols to be output and produces an invalid binary.
Fix the problem then, by removing the `forced_local' marking for the
offending case and add suitable test cases. First to verify that unused
symbols ordinarily defined with linker script assignments remain
exported in the context of input section garbage collection whether or
not a DSO defining identically named symbols is present in the link.
Second that a linker version script still correctly retains or removes
such symbols as requested.
