2014-03-18Power: Correct little-endian e500v2 GPR frame offsetsMaciej W. Rozycki2-2/+9
This change corrects GPR frame offset calculation for the e500v2 processor. On this target, featuring the SPE APU, GPRs are 64-bit and are held in stack frames whole with the use of `evstdd' and `evldd' instructions. Their integer 32-bit part occupies the low-order word and therefore its offset varies between the two endiannesses possible. * rs6000-tdep.c (rs6000_frame_cache): Correct little-endian GPR offset into SPE pseudo registers.

This is because normal_stop, as commanded by the result of bpstat_print, skips printing frame info in this case (it's an "event", not a "breakpoint"), and when the interpreter is MI, mi_on_normal_stop skips calling print_stack_frame, as the normal_stop call was already done with the MI uiout. This explains why the async output is different even with a CLI command. Its because in async mode, the mi_on_normal_stop path is always taken; it is always reached with the MI uiout, because the stop is handled from the event loop, instead of from within `proceed -> wait_for_inferior -> normal_stop' with the interpreter overridden, as in sync mode. This patch fixes the issue by making all cases output the same *stopped event, by factoring out the print code from normal_stop, and using it from mi_on_normal_stop as well. I chose the *stopped output without a frame, mainly because that is what you already get if you use MI execution commands, the commands frontends are supposed to use (except when implementing a console). This patch makes it simpler to tweak the MI output differently if desired, as we only have to change the centralized print_stop_event (taking into account whether the uiout is MI-like), and all different modes will change accordingly. Tested on x86_64 Fedora 17, no regressions. The mi-solib.exp test no longer fails in async mode with this patch, so the patch removes the kfail. 2014-03-18 Pedro Alves <palves@redhat.com> PR gdb/13860 * inferior.h (print_stop_event): Declare. * infrun.c (print_stop_event): New, factored out from ...

2014-03-17[Ada] Crash with references to GNAT packed arrays handlingPierre-Marie de Rodat2-8/+14
Consider the following declarations: type Packed_Array is array (Natural range <>) of Boolean; pragma Pack (Packed_Array); function Make (H, L : Natural) return Packed_Array is begin return (H .. L => False); end Make; A1 : Packed_Array := Make (1, 2); A2 : Packed_Array renames A1; One possible DWARF translation for A2 is: <3><1e4>: Abbrev Number: 21 (DW_TAG_variable) <1e5> DW_AT_name : a2 <1ea> DW_AT_type : <0x1d9> <3><1d9>: Abbrev Number: 22 (DW_TAG_const_type) <1da> DW_AT_type : <0x1de> <3><1de>: Abbrev Number: 23 (DW_TAG_reference_type) <1e0> DW_AT_type : <0x1a3> <3><1a3>: Abbrev Number: 17 (DW_TAG_array_type) <1a4> DW_AT_name : foo__Ta1S___XP1 <1a8> DW_AT_GNAT_descriptive_type: <0x16b> <3><16b>: Abbrev Number: 6 (DW_TAG_typedef) <16c> DW_AT_name : foo__Ta1S <172> DW_AT_type : <0x176> <3><176>: Abbrev Number: 17 (DW_TAG_array_type) <177> DW_AT_name : foo__Ta1S <17b> DW_AT_GNAT_descriptive_type: <0x223> Here, foo__Ta1S___XP1 is the type used for the code generation while foo__Ta1S is the source-level type. Both form a valid GNAT encoding for a packed array type. Trying to print A2 (1) can make GDB crash. This is because A2 is defined as a reference to a GNAT encoding for a packed array. When decoding constrained packed arrays, the ada_coerce_ref subprogram follows references and returns a fixed type from the target type, peeling the GNAT encoding for packed arrays. The remaining code assumes that the resulting type is still such an encoding while we only have a standard GDB array type, hence the crash: arr = ada_coerce_ref (arr); [...] type = decode_constrained_packed_array_type (value_type (arr)); decode_constrained_packed_array_type assumes that its argument is such an encoding. From its front comment: /* The array type encoded by TYPE, where ada_is_constrained_packed_array_type (TYPE). */ This patch simply replaces the call to ada_coerce_ref with a call to coerce_ref in order to avoid prematurely transforming the packed array type as a side-effect. This way, the remaining code will always work with a GNAT encoding. gdb/ChangeLog: * ada-lang.c (decode_constrained_packed_array): Perform a minimal coercion for reference with coerce_ref instead of ada_coerce_ref.

2014-03-14Rename native-only terminal related functions.Pedro Alves7-40/+73
Looking at target_terminal_inferior etc. in async mode, I realized that the naming of the terminal_inferior, terminal_ours, etc. functions doesn't really give a clue that they're meant for the native target only. This patch renames them. There's already child_terminal_info using the child_ prefix, and, they're most prominently installed by inf-child.c, so I went with the child_ prefix. I dropped "inferior" from a couple to make the name match the corresponding target method. Tested on x86_64 Fedora 17, and cross built for mingw. I didn't test gnu-nat.c, but I think the change is as obvious as it gets. I grepped the tree looking for other potential spots that would need adjustment but this is all I found.

2014-03-13Don't mention "Unix" in native target name.Pedro Alves4-5/+15
I find the mention of "Unix" unnecessary (and really slightly a lie) on GNU/Linux in a couple of places: (gdb) maint print target-stack The current target stack is: - multi-thread (multi-threaded child process.) - child (Unix child process) - exec (Local exec file) - None (None) (gdb) help target child Unix child process (started by the "run" command). (gdb) target child Use the "run" command to start a Unix child process. It's also odd that e.g., the Windows port says "Unix" in reaction to "target child" (it was already that way before Windows used inf-child.c): (gdb) target child Use the "run" command to start a Unix child process. (gdb) So drop "Unix", going in the direction of saying mostly the same on all native targets: (gdb) maint print target-stack The current target stack is: - multi-thread (multi-threaded child process.) - - child (Unix child process) + - child (Child process) - exec (Local exec file) - None (None) (gdb) help target child - Unix child process (started by the "run" command). + Child process (started by the "run" command).

2014-03-12Factor out foreground/background execution command preparation.Pedro Alves2-136/+61
All execution commands currently have this pattern: /* If we must run in the background, but the target can't do it, error out. */ if (async_exec && !target_can_async_p ()) error (_("Asynchronous execution not supported on this target.")); /* If we are not asked to run in the bg, then prepare to run in the foreground, synchronously. */ if (!async_exec && target_can_async_p ()) { /* Simulate synchronous execution. */ async_disable_stdin (); } This patch factors that into a shared function. attach_command installs a cleanup to re-enable stdin, but that's not necessary, as per the comment in prepare_execution_command. In any case, if someday it turns out necessary, we have a single place to install it now. Tested on x86_64 Fedora 17, sync and async modes. gdb/ 2014-03-12 Pedro Alves <palves@redhat.com> * infcmd.c (prepare_execution_command): New function, factored out from several execution commands.

2014-03-13Support for HWbreak/watchpoint across fork/vfork on arm-nativeOmair Javaid2-125/+305
This patch updates arm native support for hwbreak-/watchpoints to enable support for hwbreak-/watchpoints across fork/vfork. This involves changes to hwbreak-/watchpoint insertion mechanism to the modern way, by marking debug registers as needing update, but only really updating them on resume, which is necessary for supporting watchpoints in non-stop mode. This also updates a previously maintained per thread hwbreak-/watchpoint cache to a per process cache which allows target specific code to come in sync with gdb-linux calls to threads create/destroy and process fork/exit hooks.

2014-03-12fix regressions with target-asyncTom Tromey14-274/+325
A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

that if multiple bignum values are encountered only the most recent is valid.

2014-03-12Fix dw2-ifort-parameter.exp on PPC64Andreas Arnez3-6/+20
On PPC64, 'func' and 'main' are function descriptors and don't point to the actual code. Thus the usage of these symbols in the DWARF assembler source was broken. The patch introduces new labels func_start and func_end for this purpose.
2014-03-12Migrate dw2-ifort-parameter.exp to Dwarf::assembleAndreas Arnez3-124/+48
A "side effect" of the migration to Dwarf::assemble is that the DWARF address size is now automatically adjusted to the target architecture. The original assembler source hard-coded the DWARF address size to 4, even on 64-bit architectures. This address size mismatch caused a test case failure on s390x due to a wrong result from DW_OP_deref.

Now that prepare_for_testing etc. can cope with absolute path names, this can be exploited for test cases with generated source files. This is just to simplify the code and shouldn't cause any functional change.
