2385d90a81 * config/tc-v850.c (md_convert_frag): Make sure we insert the
fixup at the right address within the frag.

bc49fab8ea * config/tc-v850.c (md_convert_frag): Don't set fragP->fr_fix
to an absolute value, instead increment it as needed.

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.

d3bbd9dc3e * config/tc-v850.c (v850_reloc_prefix): Several disgusting
hacks to improve parsing of complex hi, lo, zda, etc
        expressions.
        (md_assemble): Don't demand and eat a trailing ')' after finding
        a v850 relocation prefix.  Sign extend the constant in a
        BFD_RELOC_LO16 expression.  Do eat a trailing ')' after a complete
        operand.
        (parse_cons_expression_v850): Don't eat a trailing ')' after
        finding a v850 relocation prefix.
Trying to get nec's sample code to assemble.  Why oh why didn't JT try
to assemble any of their code...

10fba7f14e * config/tc-v850.h (TC_PARSE_CONS_EXPRESSION): Define.
(TC_CONS_FIX_NEW): Likewise.
        * config/tc-v850.c (parse_cons_expression_v850): New function.
        (cons_fix_new_v850): Likewise.
So we can handle ".hword lo(_foo)".

7e96935e77 * config/tc-v850.c (md_pseudo_table): Add .word; allocates
4 bytes of space.
Something off the todo list.

8ea15b863f * config/tc-v850.c (md_assemble): Handle TDAOFF relocs
differently for movea & sst/sld insns.
Working on tda for the v850.

and sdaoff expressions.

0f8e50bb76 * write.c (fixup_segment): Don't add symbol value to addend if
TC_V850 and OBJ_ELF.
        * config/tc-v850.h (tc_fix_adjustable): Don't adjust any
        pc-relative fixups.
Fixing more failures in the g++ testsuite.

f964b01d90 * config/tc-v850.c (md_pcrel_from): Delete unused function.
(md_pcrel_from_section): New function.
        * config/tc-v850.h (MD_PCREL_FROM_SECTION): Define.
So we don't screw up pc-relative jumps/calls from one section
into another section within the same .o file.

Fixes global ctors/dtors to work with DECL_ONE_ONLY stuff.

2d56269edf * config/tc-v850.c (md_apply_fix3): Do simple byte, short and
word fixups too.
Fixes "difference between forward references".

74dd0c0786 * config/tc-v850.c (md_apply_fix3): Use little endian get/put
routines to fetch/store the updated instruction from/to memory.
        (v850_insert_operand): If the operand has a specialized insert
        routine, call it.
Getting fixups closer.  At least br <target> works now.

c84615bc23 * config/tc-v850.c (reg_name_search): Align calling convention to
be like identical function found in tc-ppc.c.
(get_reloc): Removed.
(v850_reloc_prefix): New function, parse lo(), hi() and hi0().
(md_assemble): emit fixups.
(md_pcrel_from): renamed from md_pcrel_from_section, emit proper
displacement.
(md_apply_fix3): handle fixups/relocs.
* config/tc-v850.h (MD_PCREL_FROM_SECTION): Removed definition.

05631de266 * config/tc-850.c (md_assemble): Handle hi() correctly. Handle
hi0() too.
Bugfix.

88b47a8521 * config/tc-v850.c (md_assemble): Rough cut at demanding
"ep" or "r30" in sst and sld instructions.
        (md_apply_fix3): Don't abort.  Just warn that we don't
        have relocs yet.

0e8f9bd15e * config/tc-v850.c (reg_name_search): Generalize to search
any given register table.
        (register_name): Pass appropriate table and size to reg_name_search.
        (system_register_name): New function.
        (SYSREG_NAME_CNT): Define.
        (md_assemble): Handle operands which are system registers.
Still working on the parser..

c9a32d6ca7 * config/tc-v850.c (md_assemble): If we find a register, but the
opcode doesn't want a register, then we don't have a match.
        (md_assemble): Get size of the instruction from the opcode table.
So we choose the right opcode and so that we get the sizes right.
