introduce the same amount of testing, but with an access to a
constrained array.
gdb/testsuite/ChangeLog:
* gdb.ada/arrayptr/foo.adb: Add access to constrained array.
* gdb.ada/arrayptr.exp: Add new tests.
A change we are making in the compiler to help preserve useful
types when using -feliminate-unused-debug-types exposed a small
hole in our value-printing code.
One example of the problem happens when trying to print a slice
of an array pointer. If the variable is defined as a pointer to
the typedef of an array, then we fail to print the slice, like so:
(gdb) p arr_ptr(1..2)
cannot take slice of non-array
gdb/ChangeLog:
* ada-lang.c (ada_is_simple_array_type, ada_value_slice_from_ptr)
(ada_value_slice, empty_array, to_fixed_array_type): Deal with
typedefs.
This rewrites the code generating the Ada exception catchpoint hit
notification for both the GDB/MI case as well as the non-MI case,
by using the relevant ui_out_* functions to generate the output.
the MI notifications for Ada exception catchpoints now include
the stop reason, and the breakpoint "disp", much like other breakpoint
events do. It also introduces a new field "exception-name" for
exception catchpoints (excluding "failed assertion catchpoints,
where we just want to know that it was a failed assertion).
gdb/ChangeLog:
* breakpoint.h (bpdisp_text): Add declaration.
* breakpoint.c (bpdisp_text): Make non-static.
* ada-lang.c: #include "mi/mi-common.h".
(print_it_exception): Rewrite to improve GDB/MI output.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Ada Exception Information): Document
the "exception-name" field in the *stopped async record.
gdb/testsuite/ChangeLog:
* gdb.ada/mi_catch_ex: New testcase.
* varobj.c (update_dynamic_varobj_children): Properly handle
errors from iterator.
gdb/testsuite
* gdb.python/py-prettyprint.py (exception_flag): New global.
(NoStringContainerPrinter._iterator.next): Check it.
* gdb.python/py-prettyprint.c (main): New variable nstype2.
* gdb.python/py-mi.exp: Set exception_flag and do more tests.

This simulates a CFI flash. Its pretty configurable via the device
tree. For now, only basic read/write/erase operations are supported
for the Intel command set, but it's easy enough to extend support.
It's certainly enough to trick Das U-Boot into using it for probing,
reading, writing, and erasing.
