gdb/ChangeLog
* common/format.c (parse_format_string): Add checks for NULL
character before calling strchr.
gdb/testsuite/ChangeLog
* gdb.base/printcmds.exp (test_printf): Add tests for format
strings with missing format specifier.
This is another simple test suite change for the parallelization
project.
This changes mi-basics.exp to avoid the use of subdir and objdir and
instead use standard_output_file.
There are still some uses of objdir, but as noted in a new comment in
the patch, these uses are parallel-safe.
* gdb.mi/mi-basics.exp: Use standard_output_file.
(test_dir_specification, test_cwd_specification)
(test_path_specification): Use testsubdir, not subdir and objdir.
This is a minor fix to clean up the last remaining test suite
parallelization issue in gdb.trace.
mi-traceframe-changed.exp refers to objdir. This patch changes the
code to have the same effect, but avoid using that variable.
* gdb.trace/mi-traceframe-changed.exp: Don't use objdir.
* ppc-linux-nat.c: Since the new PowerPC specific ptrace interface is
now available for embedded (BookE) and server (BookS) processors,
correct mentions of 'booke' and adjust comments accordingly in order to
avoid confusion. Rename struct 'booke_debug_info' to 'hwdebug_info'.
(have_ptrace_booke_interface): Rename function and variable
'have_ptrace_booke_interface' to 'have_ptrace_hwdebug_interface'.
Rename struct 'booke_debug_info' to 'hwdebug_info'. Update all uses.
(booke_cmp_hw_point): Rename function 'booke_cmp_hw_point' to
'hwdebug_point_cmp'. Update all uses.
(booke_find_thread_points_by_tid): Rename function
'booke_find_thread_points_by_tid' to
'hwdebug_find_thread_points_by_tid'. Update all uses.
(booke_insert_point): Rename function 'booke_insert_point' to
'hwdebug_insert_point'. Update all uses.
(booke_remove_point): Rename function 'booke_remove_point' to
'hwdebug_remove_point'. Update all uses.

Doug Evans committed the change above, but forgot to update one of
the callers of get_raw_print_options, at mt-tdep.c. This commit fixes
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.

2013-07-09 Pedro Alves <palves@redhat.com>
* ada-lang.c (coerce_unspec_val_to_type): Use
value_optimized_out_const.
* value.c (value_optimized_out_const): New function.
* value.h (value_optimized_out_const): New declaration.
If enough information is provided by the compiler, the debugger
now prints the entry value of various parameters:
(gdb) continue
Continuing.
Breakpoint 2, pck.call_me (w=w@entry=50) at [...]
20 Last_Word := W;
This patch adjusts the expected output to allow an optional
"w@entry=" in the parameter value.
gdb/testsuite/ChangeLog:
* gdb.ada/small_reg_param.exp: Accept optional entry value
for parameter "w".
