__builtin_frame_address (0) returns the value of the hard frame
|
|
pointer, which will point at the location of the saved PC on the

|
stack. Below this in memory is the remainder of the linkage info,
|
|
occupying 12 bytes. Therefore in order to address from
|
|
CURRENT_STACK_FRAME using "struct layout", we need to have the macro
|

return the hard FP minus 12. Of course, this makes no sense
|

without the obsolete APCS stack layout... */
