/* Rationale behind not permitting stores to bspstore...
The IA-64 architecture provides bspstore and bsp which refer
memory locations in the RSE's backing store. bspstore is the
next location which will be written when the RSE needs to write
to memory. bsp is the address at which r32 in the current frame
would be found if it were written to the backing store.
The IA-64 architecture provides read-only access to bsp and
read/write access to bspstore (but only when the RSE is in
the enforced lazy mode). It should be noted that stores
to bspstore also affect the value of bsp. Changing bspstore
does not affect the number of dirty entries between bspstore
and bsp, so changing bspstore by N words will also cause bsp
to be changed by (roughly) N as well. (It could be N-1 or N+1
depending upon where the NaT collection bits fall.)
OTOH, the linux kernel provides read/write access to bsp (and
currently read/write access to bspstore as well). But it
is definitely the case that if you change one, the other
will change at the same time. It is more useful to gdb to
be able to change bsp. So in order to prevent strange and
undesirable things from happening when a dummy stack frame
is popped (after calling an inferior function), we allow
bspstore to be read, but not written. (Note that popping
a (generic) dummy stack frame causes all registers that
were previously read from the inferior process to be written
back.) */
