/* Is the PC in a call dummy? SP and FRAME_ADDRESS are the bottom and
top of the stack frame which we are checking, where "bottom" and
"top" refer to some section of memory which contains the code for
the call dummy. Calls to this macro assume that the contents of
SP_REGNUM and DEPRECATED_FP_REGNUM (or the saved values thereof),
respectively, are the things to pass.
This won't work on the 29k, where SP_REGNUM and
DEPRECATED_FP_REGNUM don't have that meaning, but the 29k doesn't
use ON_STACK. This could be fixed by generalizing this scheme,
perhaps by passing in a frame and adding a few fields, at least on
machines which need them for DEPRECATED_PC_IN_CALL_DUMMY.
Something simpler, like checking for the stack segment, doesn't work,
since various programs (threads implementations, gcc nested function
stubs, etc) may either allocate stack frames in another segment, or
allocate other kinds of code on the stack. */
