2013-11-28Print entirely unavailable struct/union values as a single <unavailable>.Andrew Burgess4-23/+41
When printing an entirely optimized out structure/class/union, we print a single <optimized out> instead of printing <optimized out> for each field. This patch makes an entirely unavailable structure/class/union be likewise displayed with a single "<unavailable>" rather than the whole object with all fields <unavailable>. This seems good because this way the user can quickly tell whether the whole value is unavailable, rather than having to skim all fields. Consistency with optimized out values also seems to be a good thing to have. A few updates to gdb.trace/unavailable.exp where required.

2013-11-28get_prev_frame, stop_reason != UNWIND_NO_REASON, add frame debug output.Pedro Alves2-1/+38
The stop_reason != UNWIND_NO_REASON doesn't currently have "set debug frame" output.

2013-11-28get_prev_frame, outer_frame_id and unwind->stop_reason checks are redundant.Pedro Alves3-18/+13
After the previous patch, it should be clear that the this_frame->unwind->stop_reason check is redundant with the outer_frame_id check just below. We can now move the frame_id_eq comparison to the default this_frame->unwind->stop_reason callback. Tested on x86_64 Fedora 17. gdb/ 2013-11-28 Pedro Alves <palves@redhat.com> * frame-unwind.c (default_frame_unwind_stop_reason): Return UNWIND_OUTERMOST if the frame's ID is outer_frame_id. * frame.c (get_prev_frame_1): Remove outer_frame_id check.
2013-11-28get_prev_frame, UNWIND_NULL_ID -> UNWIND_OUTERMOSTPedro Alves2-6/+11
- The UNWIND_NULL_ID check in get_prev_frame_1 used to really be against null_frame_id, back before we had outer_frame_id. We didn't have UNWIND_OUTERMOST when outer_frame_id was added, but we do now, and it's more accurate. - It used to be necessary to check for the sentinel frame explicitly because that uses null_frame_id for frame id. Since no other frame can have that id nowadays (it's asserted by compute_frame_id), we don't need that explicit check. Tested on x86_64 Fedora 17. gdb/ 2013-11-28 Pedro Alves <palves@redhat.com> * frame.c (get_prev_frame_1): If the frame id is outer_frame_id, set the unwind stop reason to UNWIND_OUTERMOST, not UNWIND_NULL_ID. Remove explicit check for sentinel frame.

2013-11-27Fix type of not saved registers.Pedro Alves2-1/+13
value_of_register_lazy uses the type of REGNUM in FRAME, but given multi-arch, the arch of FRAME might be different from the previous frame's arch, and therefore the type of register REGNUM should be retrieved from the unwound arch. This used to be correct before the previous change. Tested on x86_64 Fedora 17. gdb/ 2013-11-27 Pedro Alves <palves@redhat.com> * frame-unwind.c (frame_unwind_got_optimized): Use the type of the register in the previous frame's arch.
2013-11-27Make "set debug frame 1" output print <not saved> instead of <optimized out>.Pedro Alves2-3/+10
"set debug frame 1" is printing "<optimized out>" for not saved registers. That's because the unwinders are returning optimized out not_lval values instead of optimized out lval_register values. "<not saved>" is how val_print_optimized_out prints lval_register values. ... - { frame_unwind_register_value (frame=0,regnum=7(rsp),...) -> <optimized out> } + { frame_unwind_register_value (frame=0,regnum=7(rsp),...) -> <not saved> } ...

Similar to stack cache, in this patch, we add TARGET_OBJECT_CODE_MEMORY to read code from target and add a new option "set code-cache on|off" to optimize code accesses by using the target memory cache. In V4: - Remove "without affecting correctness" from NEWS and doc. - Replace "ON" with "on" in doc. - "access" -> "accesses". In V3: - Rename functions and variables. - Update command help, doc and NEWS entry. - Invalidate cache on option transitions, to align with the behaviour of "stack-cache". Since cache invalidation is transparent to users, users don't know option "stack-cache" transitions cause code cache invalidation. V2 was reviewed by Doug. There are some changes in V3, so I post it here. gdb: 2013-11-24 Yao Qi <yao@codesourcery.com> * NEWS: Add note on new "set code-cache" option. * target-dcache.c (code_cache_enabled_1): New variable.

2013-11-24Renaming in target-dcache.cYao Qi4-18/+34
Hi, This patch does some renamings on "stack-cache" related functions and variables. In the review to "code cache" series v2, we have some discussions on the name of predicate function 'stack_cache_enabled', and have some options, 1 keep it unchanged, as it is already a predicate clearly, 2 rename it to stack_cache_enabled_p, 3 rename it to enable_stack_cache_p, I choose #2, because 'stack_cache_enabled' is a predicate, but it's better to add "_p" suffix to stress this. There are some other similar patterns used in GDB source, such as unop_user_defined_p and agent_loaded_p. Then, I have to rename variable stack_cache_enabled_p to something else. The option is "stack-cache", so I'd like to name the variable associated with this command as "stack_cache". Similarly, the commands associated with this command should be renamed to "set_stack_cache" and "show_stack_cache" respectively. gdb: 2013-11-24 Yao Qi <yao@codesourcery.com> * target-dcache.c (stack_cache_enabled_p_1): Rename to ...
