Doug Evans committed the change above, but forgot to update one of

this.
2013-07-10 Sergio Durigan Junior <sergiodj@redhat.com>
* mt-tdep.c (mt_registers_info): Call
get_no_prettyformat_print_options instead of
get_raw_print_options (regression by last patch from Doug
Evans).
This patch adds some tests that evidence a regression fixed by
the following patch from Pedro Alves:
[PATCH] ada-lang.c:coerce_unspec_val_to_type: Preserve laziness
http://www.sourceware.org/ml/gdb-patches/2013-07/msg00178.html
gdb/testsuite/ChangeLog:
* gdb.ada/arrayptr/foo.adb: Add some code defining an access
to a packed array.
* gdb.ada/arrayptr.exp: Add a few tests using that new access
to packed array.
ada-lang.c:coerce_unspec_val_to_type does:
if (value_lazy (val)
|| TYPE_LENGTH (type) > TYPE_LENGTH (value_type (val)))
result = allocate_value_lazy (type);
else
{
result = allocate_value (type);
memcpy (value_contents_raw (result), value_contents (val),
TYPE_LENGTH (type));
}
set_value_component_location (result, val);
set_value_bitsize (result, value_bitsize (val));
set_value_bitpos (result, value_bitpos (val));
set_value_address (result, value_address (val));
set_value_optimized_out (result, value_optimized_out (val));
Notice that before value_optimized_out was made to auto-fetch lazy
values, VAL would end up still lazy if it was lazy on entry. It's not
really a problem here if VAL is lazy, and VAL->optimized_out is 0,
because RESULT is also left lazy. IOW, this just wants to copy the
VAL->optimized_out flag to RESULT->optimized_out, nothing else.
As a side-effect of the change in value_optimized_out, the following
testcase now regresses. Consider:
type Small is range -64 .. 63;
for Small'Size use 7;
type Arr is array (1..10) of Small;
pragma Pack (Arr);
type Arr_Ptr is access Arr;
An_Arr_Ptr : Arr_Ptr := new Arr'(10, 20, 30, 40, 50, 60, 62, 63,
-23, 42);
Trying to print one element of An_Arr_Ptr yields:
(gdb) p an_arr_ptr(3)
Cannot access memory at address 0x0
The patch adds the value_optimized_out_const function for that,
allowing us to avoid trying to fetch a value at a dummy address.
(I found this out by grepping for set_value_optimized_out and trying
to convert the uses I found to instead allocate the value with
allocate_optimized_out_value.)
Tested on x86_64 Fedora 17.

(offset_high_part, small_offset_p): New functions.
(nacro): Use them. Remove *_OB and *_DOB cases. For single-
register load and store macros, handle the 16-bit offset case first.
If a 16-bit offset is not suitable for the instruction we're
generating, load it into the temporary register using
ADDRESS_ADDI_INSN. Make the M_LI_DD code fall through into the
M_L_DAB code once the address has been constructed. For double load
and store macros, again handle the 16-bit offset case first.
If the second register cannot be accessed from the same high
part as the first, load it into AT using ADDRESS_ADDI_INSN.
Fix the handling of LD in cases where the first register is the
same as the base. Also handle the case where the offset is
not 16 bits and the second register cannot be accessed from the
same high part as the first. For unaligned loads and stores,
fuse the offbits == 12 and old "ab" handling. Apply this handling
whenever the second offset needs a different high part from the first.
Construct the offset using ADDRESS_ADDI_INSN where possible,
for offbits == 16 as well as offbits == 12. Use offset_reloc
when constructing the individual loads and stores.
(mips_ip): Set up imm_expr, imm2_expr, offset_expr, imm_reloc
and offset_reloc before matching against a particular opcode.
Handle elided 'A' constants. Allow 'A' constants to use
relocation operators.
