+ * elf32-s390.c (allocate_dynrelocs): For undef weak syms with
+ non-default visibility, a) don't make them dynamic, b) discard
+ space for dynamic relocs.
+ (elf_s390_relocate_section): Initialize the GOT entries and skip
+ R_390_{8,16,32}/R_390_PC{16,16DBL,32DBL,32} for weak undefined
+ symbols with non-default visibility.
+ * elf64-s390.c: Likewise.
+
2003-05-09 Alan Modra <amodra@bigpond.net.au>
* cpu-arm.c (arm_check_note): Warning fix.
