When one of the parameter values in a subprogram calls is an array
whose value does not come from inferior memory, the debugger first
copies the array value in inferior memory. Up to now, the memory
used to hold that copy was taken from the stack (just below the SP),
but this is causing problems on SPARC v9.
So the immediate fix is to follow what C does with arrays and strings,
which is allocate memory on the heap.
gdb/ChangeLog:
* ada-lang.c: #include "value.h".
(ensure_lval): Delete advance declaration. Remove gdbarch and sp
arguments. Implement using value_allocate_space_in_inferior
instead of allocating memory from the stack.
(make_array_descriptor): Remove gdbarch and sp parameters. Update
calls to ensure_lval.
(ada_convert_actual): Remove gdbarch and sp parameters. Update
calls to make_array_descriptor and ensure_lval.
* ada-lang.h (ada_convert_actual): Update declaration.
* infcall.c (value_arg_coerce): Update call to ada_convert_actual.
* infcall.c: White space.
* inf-child.c: White space.
* infcmd.c: White space.
* inferior.c: White space.
* inf-loop.c: White space.
* inflow.c: White space.
* inline-frame.c: White space.
* interps.c: White space.
* infcall.c (call_function_by_hand): Remove gdb_assert on sp and old_sp.
New comment.
gdb/testsuite/
* gdb.base/callfuncs.exp: New tests for $spval 0 and -1. Remove return.
for the new regcache. All callers updated.
(regcache_cpy, regcache_cpy_no_passthrough): Do not set aspace here.
