Alan Modra	ef5a96d564	Remove ppc860, ppc750cl, ppc7450 insns from common ppc. Back in the day support for these processors was added, we probably didn't want to waste PPC_OPCODE bits on minor variations. I've had a complaint that disassembly of mfspr/mtspr was wrong for power8. This patch fixes that problem. Note that since -m860/-m850/-m821 are new gas options enabling the mpc8xx specific mfspr/mtspr variants it is possible that this change will break some mpc8xx assembly code. ie. you might need to modify makefiles to pass -m860 to gas. include/opcode/ * ppc.h (PPC_OPCODE_750, PPC_OPCODE_7450, PPC_OPCODE_860): Define. opcodes/ * ppc-opc.c (PPC750, PPC7450, PPC860): Define using PPC_OPCODE_. ppc-dis.c (ppc_opts): Add 821, 850 and 860 entries.

Kevin Buettner	1b485e6778	Add support for backtracing through Renesas RX exception frames. This change adds support for backtracing through Renesas RX exception frames. Determination about the type of frame is made by scanning the remainder of the function for a return instruction and then looking at which, if any, return instruction is found. A normal RTS instruction indicates that the frame is a normal frame. An RTFI instruction indicates that it's a fast interrupt, and an RTE instruction indicates that the frame is a (normal) exception frame. If no return instruction is found within the scanned region - which can happen when the end of the function cannot be found - it is assumed to be a normal frame. I was able to test that normal prologue scanning still works by disabling the dwarf2 sniffer. I've tested this code for normal interrupts. The fast interrupt case has not been tested. gdb/ChangeLog: * rx-tdep.c (RX_USP_REGNUM, RX_BPC_REGNUM): New constants. (enum rx_frame_type): New. (struct rx_prologue): Add new field `frame_type'.

Patrick Palka	bbcbf914a6	TUI: Make sure to update registers if frame information has changed When I replaced TUI's frame_changed hook to fix PR tui/13378 I assumed that there's no reason to refresh register information following a call to "up", "down" or "frame". This assumption was made to fix the problem of refreshing frame information twice following a sync-execution normal stop (once in tui_normal_stop and then in tui_before_prompt) -- the second refresh removing any highlights made by the first. I was wrong about that -- GDB's snapshot of register information is per-frame, and when the frame changes, registers do too (most prominently the %rip and %rsp registers). So e.g. GDB 7.8 would highlight such register changes after invoking "up", "down" or "frame", and current GDB does not. To fix this regression, this patch adds another (sufficient) condition for refreshing register information: in tui_refresh_frame_and_register_information, always refresh register information if frame information has changed. This makes register information get refreshed following a call to "up", "down" or "frame" while still avoiding the "double refresh" issue following a normal stop. This condition may seem to obsolete the existing registers_too_p parameter, but it does not: following a normal stop, it is possible that registers may have changed while frame information had not. We could be on the exact same PC with different register values. The new condition would not catch such a case, but the registers_too_p condition will. So both conditions seem necessary (and either one is sufficient). gdb/ChangeLog: * tui/tui-hooks.c (tui_refresh_frame_and_register_information): Update commentary. Always refresh the registers when frame information has changed. * tui/tui-stack.c (tui_show_frame_info): Update commentary. Change return type to int.

Patrick Palka	0986c744df	Replace TUI's select_frame hook (PR tui/13378) The select_frame hook is used by TUI to update TUI's frame and register information following changes to the selected frame. The problem with this hook is that it gets called after every single frame change, even if the frame change is only temporary or internal. This is the primary cause of flickering and slowdown when running the inferior under TUI with conditional breakpoints set. Internal GDB events are the source of many calls to select_frame and these internal events are triggered frequently, especially when a few conditional breakpoints are set. This patch removes the select_frame hook altogether and instead makes the frame and register information get updated in two key places (using observers): after an inferior stops, and right before displaying a prompt. The latter hook covers the case when frame information must be updated following a call to "up", "down" or "frame", and the former covers the case when frame and register information must be updated after a call to "continue", "step", etc. or after the inferior stops in async execution mode. Together these hooks should cover all the cases when frame information ought to be refreshed (and when the relevant windows ought to be subsequently updated). The print_frame_info_listing hook is also effectively obsolete now, but it still must be set while the TUI is active because its caller print_frame_info will otherwise assume that the CLI is active, and will print the frame informaion accordingly. So this patch also sets the print_frame_info_listing hook to a dummy callback, in lieu of outright removing it yet. Effectively, with this patch, frame/PC changes that do not immediately precede an inferior-stop event or a prompt display event no longer cause TUI's frame and register information to be updated. And as a result of this change and of the previous change to tui_show_frame_info, the TUI is much more disciplined about updating the screen, and so the flicker as described in the PR is totally gone. gdb/ChangeLog: PR tui/13378 * frame.c (select_frame): Remove reference to deprecated_selected_frame_level_changed_hook. * frame.h (deprecated_selected_frame_level_changed_hook): Remove declaration. * stack.c (deprecated_selected_frame_level_changed_hook): Likewise. * tui/tui-hooks.c (tui_selected_frame_level_changed_hook): Rename to ...

Patrick Palka	b5fca6d728	Be lazy about refreshing the windows in tui_show_frame_info (PR tui/13378) tui_show_frame_info is responsible for updating the visible windows following a change in frame information (that being the currently selected frame, PC, line number, etc). Currently it always redraws and refreshes each window even if frame information has not changed. This behavior is inefficient and helps contribute to the occassional flickering of the TUI as described in the mentioned PR. This patch makes tui_show_frame_info refresh the windows only if frame information has changed. Determining whether frame information has changed is done indirectly by determining whether the locator has changed. This approach is convenient and yet sensible because the locator contains all the relevant info we need to check anyway: the current PC, the line number, the name of the executable and the name of the current function. Probably only the PC is really necessary to check, but it doesn't hurt to check every field. Effectively, with this patch, consecutive calls to select_frame with the same frame/PC no longer cause TUI's frame information to be updated multiple times. gdb/ChangeLog: PR tui/13378 * tui/tui-stack.c (tui_set_locator_info): Change prototype to return an int instead of void. Return whether the locator window has changed. (tui_show_frame_info): If the locator info has not changed, then bail out early to avoid refreshing the windows.	11 years ago
Patrick Palka	c45613e33d	Correctly initialize the TUI locator window The call to tui_alloc_content in tui_set_locator_info passes locator->type as the type of the window whose content is being allocated. This may seem correct but it's actually not because when this code path actually get executed locator->type has not yet been to set LOCATOR_WIN so it defaults to 0 i.e. SRC_WIN. Thus we allocate the content of the locator window as if it was the source window. This oversight turns out not to be a big deal in practice but the patch that follows depends on the locator's proc_name and full_name arrays to be initialized to the empty string which is done by tui_alloc_content if we pass to it LOCATOR_WIN. This patch fixes this bug by explicitly passing LOCATOR_WIN to tui_alloc_content. gdb/ChangeLog: * tui/tui-stack.c (tui_set_locator_info): Explicitly pass LOCATOR_WIN to tui_alloc_content.	11 years ago

Pedro Alves	28bf096c62	PR threads/18127 - threads spawned by infcall end up stuck in "running" state Refs: https://sourceware.org/ml/gdb/2015-03/msg00024.html https://sourceware.org/ml/gdb/2015-06/msg00005.html On GNU/Linux, if an infcall spawns a thread, that thread ends up with stuck running state. This happens because: - when linux-nat.c detects a new thread, it marks them as running, and does not report anything to the core. - we skip finish_thread_state when the thread that is running the infcall stops. As result, that new thread ends up with stuck "running" state, even though it really is stopped. On Windows, _all_ threads end up stuck in running state, not just the one that was spawned. That happens because when a new thread is detected, unlike linux-nat.c, windows-nat.c reports TARGET_WAITKIND_SPURIOUS to infrun. It's the fact that that event does not cause a user-visible stop that triggers the problem. When the target is re-resumed, we call set_running with a wildcard ptid, which marks all thread as running. That set_running is not suppressed because the (leader) thread being resumed does not have in_infcall set. Later, when the infcall finally finishes successfully, nothing marks all threads back to stopped. We can trigger the same problem on all targets by having a thread other than the one that is running the infcall report a breakpoint hit to infrun, and then have that breakpoint not cause a stop. That's what the included test does. The fix is to stop GDB from suppressing the set_running calls while doing an infcall, and then set the threads back to stopped when the call finishes, iff they were originally stopped before the infcall started. (Note the MI running/stopped event suppression isn't affected.)
