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.
