Linker segfaults with undefined weak function descriptors.
Last modified: 2009-01-22 10:56:41 UTC
This test file segfaults ld:
# These should both end up zero.
sec is NULL at the top of _frvfdpic_emit_got_relocs_plt_entries. Discovered
while cribbing from the FRV port for SH FDPIC - presumably both should be zero
and have no relocations. That's what happens for the non-hidden one.

It does fix the crash, but two unnecessary function descriptors appear
to be allocated. And I get an assertion failure on elf32-frv.c:5867
if I add -shared to the link command (along with a corrupt
relocation in .rel.dyn).
If I link the executable with a shared library I get a dynamic reloc
for the non-hidden undefweak symbol, which IMO is correct.
