PR middle-end/30311
* 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.
