Hi,
the s390 IFUNC support so far didn't deal correctly with PLTOFF
relocs. Fixed with the attached patch.
Committed.
Bye,
-Andreas-
2012-09-03 Andreas Krebbel <Andreas.Krebbel@de.ibm.com>
* elf32-s390.c (elf_s390_relocate_section): Handle PLTOFF for
local and global ifunc symbols.
* elf64-s390.c (elf_s390_relocate_section): Likewise.
