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.

2014-03-13Rename Solaris's target to "target child" like most other ports.Pedro Alves4-7/+9
Note that "target procfs" is used by QNX, but the test must be failing there, as nto-procfs.c overrides to_open with a method that doesn't throw the error being tested. So I'm just removing the test completely. gdb/ 2014-03-13 Pedro Alves <palves@redhat.com> * procfs.c (procfs_target): Don't override to_shortname, to_longname or to_doc. gdb/testsuite/ 2014-03-13 Pedro Alves <palves@redhat.com> * gdb.base/default.exp: Don't test "target procfs".
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). (gdb) target child -Use the "run" command to start a Unix child process. +Use the "run" command to start a child process. gdb/ 2014-03-13 Pedro Alves <palves@redhat.com> * inf-child.c (inf_child_open, inf_child_target): Don't mention Unix in user visible strings. gdb/testsuite/ 2014-03-13 Pedro Alves <palves@redhat.com> * gdb.base/default.exp: Update "target child" and "target procfs" tests to not expect "Unix".

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. (run_command_1, continue_command, step_1, jump_command) (signal_command, until_command, advance_command, finish_command) (attach_command): Use prepare_execution_command.
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.
