Jeff Law a334533c1b * config/tc-v850.h (TC_GENERIC_RELAX_TABLE): Define.
* config/tc-v850.c: Fix some indention problems.
        (md_relax_table): Define for D9->D99 branch displacement
        relaxing.
        (md_convert_frag): Do something useful instead of aborting.
        (md_estimate_size_before_relax): Likewise.
        (md_assemble): Note if the matching instruction has a relaxable
        operand.  If it does, allocate frag with frag_var and don't
        do any fixups.
So we can do 9bit displacement to 22bit displacement relaxing.
