* cgen.c (gas_cgen_save_fixups): Modified to allow more than one
set of fixups to be stored.
(gas_cgen_restore_fixups): Modified to allow the fixup chain to be
restored to be chosen from any that are saved.
(gas_cgen_swap_fixups): Modified to allow the current set of
fixups to be swapped with any other set that has been saved.
(gas_cgen_initialize_saved_fixups_array): New routine.
* cgen.h: Modifed prototypes for gas_cgen_save_fixups,
gas_cgen_restore_fixups, and gas_cgen_swap_fixups. Added definitions
or MAX_SAVED_FIXUP_CHAINS.
* config/tc-m32r.c (assemble_two_insns): Changed calls to fixup
store, swap and restore fuctions to reflect the new interface.
larger.
(relax_frag): Add segment parameter. Only call symbol_get_frag
once. Only call is_dnrange if the symbol is in the same segment,
and the symbol address is larger.
(relax_segment): Pass segment to md_relax_frag and relax_frag.
* write.h (relax_frag): Update declaration.
* config/tc-fr30.c (fr30_relax_frag): Add segment parameter. Pass
it to relax_frag.
* config/tc-m32r.c (m32r_relax_frag): Likewise.
* config/tc-m32r.h (md_relax_frag): Add segment parameter.
(m32r_relax_frag): Update declaration.
* config/tc-mips.h (md_relax_frag): Add segment parameter.
* config/tc-tic54x.h (md_relax_frag): Likewise.
* doc/internals.texi (CPU backend): Update documentation for
md_relax_frag.
* config/tc-m32r.c (enable_m32rx): New static global.
(enable_special,warn_explicit_parallel_conflicts,optimize): Ditto.
(allow_m32rx): New function.
(M32R_SHORTOPTS): Add `O'.
(md_longopts): Add --m32rx plus several warning options.
(md_parse_option): Handle new options.
(md_show_usage): Print them.
(md_begin): Enable m32rx.
(OPERAND_IS_COND_BIT): New macro.
(first_writes_to_seconds_operands): New function.
(writes_to_pc,can_make_parallel,make_parallel): New functions.
(target_make_parallel,assemble_two_insns): New functions.
(md_assemble): Recognize "insn1 -> insn2" and "insn1 || insn2".
If optimizing and m32rx, try to make consecutive insns parallel.
