Hi,
as Jakub noticed I just fixed the same bug independently by
https://gcc.gnu.org/ml/gcc-patches/2015-02/msg01004.html
The fix is bit different. It adds DECL_EXTERNAL check in addition to
node->definition.
Concerning discussion here, node->definition really just means that the
definition is there at the time you check the flag. It does not imply it will
be output - it can be removed later by IPA optimization or it may be a
definition of external variable or alias.
Using node->process flag is not a good idea, because these flags are set only
while generating final assembler output, while we use binds_local_p during IPA
optimization, too.
I see nothing wrong with dropping the use of ->definition flag as suggested by
Richard. It is probably good cleanup compared to my change. The lto-cgraph.c
and symtab.c parts of my change are still useful to fix some of nonsenses WRT
definitions and ltrans partitions.
