Add support for mips16 (16 bit MIPS implementation):
* gencode.c (inst_type): Add mips16 instruction encoding types.
(GETDATASIZEINSN): Define.
(MIPS_DECODE): Add REG flag to dsllv, dsrav, and dsrlv. Add
jalx. Add LEFT flag to mfhi and mflo. Add RIGHT flag to mthi and
mtlo.
(MIPS16_DECODE): New table, for mips16 instructions.
(bitmap_val): New static function.
(struct mips16_op): Define.
(mips16_op_table): New table, for mips16 operands.
(build_mips16_operands): New static function.
(process_instructions): If PC is odd, decode a mips16
instruction. Break out instruction handling into new
build_instruction function.
(build_instruction): New static function, broken out of
process_instructions. Check modifiers rather than flags for SHIFT
bit count and m[ft]{hi,lo} direction.
(usage): Pass program name to fprintf.
(main): Remove unused variable this_option_optind. Change
``*loptarg++'' to ``loptarg++''.
(my_strtoul): Parenthesize && within ||.
* interp.c (sim_trace): If tracefh is NULL, set it to stderr.
(LoadMemory): Accept a halfword pAddr if vAddr is odd.
(simulate): If PC is odd, fetch a 16 bit instruction, and
increment PC by 2 rather than 4.
* configure.in: Add case for mips16*-*-*.
* configure: Rebuild.
