        * config/mips/mips.h (reg_class): Remove V1_REG.
        (REG_CLASS_NAMES, REG_CLASS_CONTENTS): Update accordingly.
        * config/mips/mips.c (mips_regno_to_class): Map $3 to M16_NA_REGS
        instead of V1_REGS.
        (mips_get_tp): New function.
        (mips_legitimize_tls_address): Use it.
        * config/mips/constraints.md (v): Delete.
        * config/mips/mips.md (TLS_GET_TP_REGNUM): New constant.
        (tls_get_tp_<mode>): Allow any GPR destination and clobber $3.
        After reload, split into a move and ...
        (*tls_get_tp_<mode>_split): ...this new instruction.
