        * caller-save.c (add_stored_regs): Only handle SUBREGs if inner
        REG is a hard register.  Do not modify REG before calling
        subreg_nregs.
        * rtlanal.c (subreg_get_info): Don't assert size of XMODE is a
        multiple of the size of YMODE for certain lowpart cases.

gcc/testsuite:
        * gcc.c-torture/compile/pr30311.c: New test.
