-/* The a29k user's guide documents well what the stacks look like.
- But what isn't so clear there is how this interracts with the
- symbols, or with GDB.
- In the following saved_msp, saved memory stack pointer (which functions
- as a memory frame pointer), means either
- a register containing the memory frame pointer or, in the case of
- functions with fixed size memory frames (i.e. those who don't use
- alloca()), the result of the calculation msp + msize.
-
- LOC_ARG, LOC_LOCAL - For GCC, these are relative to saved_msp.
- For high C, these are relative to msp (making alloca impossible).
- LOC_REGISTER, LOC_REGPARM - The register number is the number at the
- time the function is running (after the prologue), or in the case
- of LOC_REGPARM, may be a register number in the range 160-175.
-
- The compilers do things like store an argument into memory, and then put out
- a LOC_ARG for it, or put it into global registers and put out a
- LOC_REGPARM. Thus is it important to execute the first line of
- code (i.e. the line of the open brace, i.e. the prologue) of a function
- before trying to print arguments or anything.
-
- The following diagram attempts to depict what is going on in memory
- (see also the _a29k user's guide_) and also how that interacts with
- GDB frames. We arbitrarily pick fci->frame to point the same place
- as the register stack pointer; since we set it ourself in
- INIT_EXTRA_FRAME_INFO, and access it only through the FRAME_*
- macros, it doesn't really matter exactly how we
- do it. However, note that FRAME_FP is used in two ways in GDB:
- (1) as a "magic cookie" which uniquely identifies frames (even over
- calls to the inferior), (2) (in PC_IN_CALL_DUMMY [ON_STACK])
- as the value of SP_REGNUM before the dummy frame was pushed. These
- two meanings would be incompatible for the a29k if we defined
- CALL_DUMMY_LOCATION == ON_STACK (but we don't, so don't worry about it).
- Also note that "lr1" below, while called a frame pointer
- in the user's guide, has only one function: To determine whether
- registers need to be filled in the function epilogue.
-
- Consider the code:
- < call bar>
- loc1: . . .
- bar: sub gr1,gr1,rsize_b
- . . .
- add mfp,msp,0
- sub msp,msp,msize_b
- . . .
- < call foo >
- loc2: . . .
- foo: sub gr1,gr1,rsize_f
- . . .
- add mfp,msp,0
- sub msp,msp,msize_f
- . . .
- loc3: < suppose the inferior stops here >

+/* OBSOLETE as the register stack pointer; since we set it ourself in */
+/* OBSOLETE INIT_EXTRA_FRAME_INFO, and access it only through the FRAME_* */
+/* OBSOLETE macros, it doesn't really matter exactly how we */
+/* OBSOLETE do it. However, note that FRAME_FP is used in two ways in GDB: */
+/* OBSOLETE (1) as a "magic cookie" which uniquely identifies frames (even over */
+/* OBSOLETE calls to the inferior), (2) (in PC_IN_CALL_DUMMY [ON_STACK]) */
+/* OBSOLETE as the value of SP_REGNUM before the dummy frame was pushed. These */
+/* OBSOLETE two meanings would be incompatible for the a29k if we defined */
+/* OBSOLETE CALL_DUMMY_LOCATION == ON_STACK (but we don't, so don't worry about it). */
