Stores, into a struct frame_saved_regs,

the addresses of the saved registers of frame described by FRAME_INFO.
|

This includes special registers such as pc and fp saved in special
|
||
ways in the stack frame. sp is even more special:
|
||
the address we return for it IS the sp for the next frame.
|
||
|

Note that on register window machines, we are currently making the

assumption that window registers are being saved somewhere in the
|
||
frame in which they are being used. If they are stored in an
|
||
inferior frame, find_saved_register will break.
|
||
|
||
On the Sun 4, the only time all registers are saved is when
|
||
a dummy frame is involved. Otherwise, the only saved registers
|
||
are the LOCAL and IN registers which are saved as a result
|
||
of the "save/restore" opcodes. This condition is determined
|
||
by address rather than by value.
|
||
|
||
The "pc" is not stored in a frame on the SPARC. (What is stored
|
||
is a return address minus 8.) sparc_pop_frame knows how to
|
||
deal with that. Other routines might or might not.
