Subject:         * config/mips/tm-linux.h (REALTIME_LO, REALTIME_HI): Define
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf0729999558578f7f7e011b47c93a325b91ebf8;p=binutils-gdb.git

    * config/mips/tm-linux.h (REALTIME_LO, REALTIME_HI): Define
        conditionally.
        (JB_PC, JB_ELEMENT_SIZE): Rename to MIPS_LINUX_JB_PC and
        MIPS_LINUX_JB_ELEMENT_SIZE.
        * mips-linux-tdep.c (supply_gregset, fill_gregset): Use alloca
        for MAX_REGISTER_RAW_SIZE arrays.
        (mips_linux_get_longjmp_target): Use MIPS_LINUX_JB_PC and
        MIPS_LINUX_JB_ELEMENT_SIZE.
