* elf32-v850.c (v850_elf_reloc, v850_elf_final_link_relocate):
Correct value for maximum positive 22 bit PC relative relocation.
(v850_elf_final_link_relocate): Prevent overflow from HI16_S and
HI_16 relocations. Correct bit adjustment in TDA offsets.
Thu Oct 9 16:43:39 1997 Doug Evans <dje@canuck.cygnus.com>
* elf64-sparc.c (sparc_elf_{hix22,lox10}_reloc): New functions.
