/* A traditional saved regs table, indexed by REGNUM, encoding where

the value of REGNUM for the previous frame can be found in this

frame.

The table is initialized with an identity encoding (ADDR == 0,

previous frame can be found in register REGNUM (== REALNUM) in this

frame.

The initial encoding can then be changed:

|
|
Modify ADDR (REALNUM >= 0, ADDR != 0) to indicate that the value of
|
|
register REGNUM in the previous frame can be found in memory at
|
|
ADDR in this frame.
|
|
|
|
Modify REALNUM (REALNUM >= 0, ADDR == 0) to indicate that the value
|
|
of register REGNUM in the previous frame is found in register
|
|
REALNUM in this frame.
|
|
|
|
Call trad_frame_register_value (REALNUM < 0) to indicate that the

value of register REGNUM in the previous frame is found in ADDR. */
