# As compared to ordinary remote 29K debugging, this changes the register
# numbering a bit, to hold kernel regs, and adds support for looking at

/* The am29k 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 _am29k 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 29k 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 >

vendor's termio tgetent() routine. It always works when run under

After some poking around, it appears that depending on the environment
size, or whether you're running YP, or the phase of the moon or something,
the stack is not always long-aligned when main() is called, and tgetent()
takes strong offense at that. On some machines this bug never appears, but
