+ Find register number REGNUM relative to FRAME and put its (raw,

+
+ Set *OPTIMIZED if the variable was optimized out (and thus can't be
+ fetched). Note that this is never set to anything other than zero
+ in this implementation.
+
+ 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). We will use not_lval for values
+ fetched from generic dummy frames.
+
+ Set *ADDRP to the address, either in memory or as a
+ DEPRECATED_REGISTER_BYTE offset into the registers array. If the
+ value is stored in a dummy frame, set *ADDRP to zero.
+
+ The argument RAW_BUFFER must point to aligned memory.
+
+ The GET_SAVED_REGISTER architecture interface is entirely
+ redundant. New architectures should implement per-frame unwinders
