/* DEFAULT_GET_SAVED_REGISTER ()
Find register number REGNUM relative to FRAME and put its (raw,
target format) contents in *RAW_BUFFER. Set *OPTIMIZED if the
variable was optimized out (and thus can't be fetched). Set *LVAL
to lval_memory, lval_register, or not_lval, depending on whether
the value was fetched from memory, from a register, or in a strange
and non-modifiable way (e.g. a frame pointer which was calculated
rather than fetched). Set *ADDRP to the address, either in memory
on as a REGISTER_BYTE offset into the registers array.
Note that this implementation never sets *LVAL to not_lval. But
it can be replaced by defining GET_SAVED_REGISTER and supplying
your own.
The argument RAW_BUFFER must point to aligned memory. */
