2015-07-06Fix problems with finishing a dummy function call on simulators.gdb-7.10-branchpointLuis Machado2-10/+8
This fixes regressions introduced with the original change to not consider permanent breakpoints always inserted: 6ae8866180bf90e9ec76c2dd34c07fd826d11a83 is the first bad commit commit 6ae8866180bf90e9ec76c2dd34c07fd826d11a83 Author: Luis Machado <lgustavo@codesourcery.com> Date: Wed Jun 17 16:50:57 2015 -0300 Fix problems with finishing a dummy function call on simulators. Some checks were mistakenly left out of the original patch, which caused the following failures: -PASS: gdb.base/shlib-call.exp: print mainshr1(1) -PASS: gdb.base/shlib-call.exp: step into mainshr1 +FAIL: gdb.base/shlib-call.exp: print mainshr1(1) +FAIL: gdb.base/shlib-call.exp: step into mainshr1 -PASS: gdb.cp/chained-calls.exp: q(p()) +FAIL: gdb.cp/chained-calls.exp: q(p()) -PASS: gdb.cp/chained-calls.exp: q(p() + r()) +FAIL: gdb.cp/chained-calls.exp: q(p() + r()) -PASS: gdb.cp/chained-calls.exp: g(f(g(f() + f())) + f()) +FAIL: gdb.cp/chained-calls.exp: g(f(g(f() + f())) + f()) -PASS: gdb.cp/chained-calls.exp: *c -PASS: gdb.cp/chained-calls.exp: *c + *c -PASS: gdb.cp/chained-calls.exp: q(*c + *c) +FAIL: gdb.cp/chained-calls.exp: *c +FAIL: gdb.cp/chained-calls.exp: *c + *c +FAIL: gdb.cp/chained-calls.exp: q(*c + *c) -PASS: gdb.cp/classes.exp: calling method for small class +FAIL: gdb.cp/classes.exp: calling method for small class The above is likely caused by GDB not removing the permanent breakpoints from the target, leading to the inferior executing the breakpoint instruction and tripping on a SIGSEGV. gdb/ChangeLog: 2015-07-06 Luis Machado <lgustavo@codesourcery.com> * breakpoint.c (remove_breakpoint_1): Don't handle permanent breakpoints in a special way.

2015-07-06gdb/doc: Fix incorrect use of @xref.Andrew Burgess2-1/+5
All uses of @xref must be followed by either '.' or ','. In commit a4ea0946c an incorrect use of @xref was introduced. This commit adds a comma after the use of @xref. gdb/ChangeLog: * doc/gdb.texinfo (TUI): Add comma after @xref.
2015-07-06gdb/tui: Don't cast between window types.Andrew Burgess2-2/+6
Instead of casting between structure types to get the 'tui_gen_win_info' info from a 'tui_win_info' access the generic member variable. This is inline with what is done throughout the rest of the tui code. gdb/ChangeLog: * tui/tui-win.c (tui_set_focus): Use structure member 'generic' instead of casting the structure type.
2015-07-06search_struct_field: remove OFFSET parameterSimon Marchi2-12/+18
I was trying to understand what the OFFSET parameter was for, and realized it was set to 0 in every call to search_struct_field. I assume that it was used at some point, but some subsequent changes made it useless. gdb/ChangeLog: * valops.c (search_struct_field): Remove OFFSET parameter. (value_cast_structs): Adjust calls to search_struct_field. (value_struct_elt): Same. (find_overload_match): Same.
2015-07-06Cleanup value_fetch_lazy's comment and return valueSimon Marchi3-13/+12
The comment for value_fetch_lazy seems outdated. It says that it's only called from the value_contents and value_contents_all (macros!), which is not true. Also, the return value seems useless now, despite what the comment says. gdb/ChangeLog: * value.c (value_fetch_lazy): Update comment, change return value to void. * value.h (value_fetch_lazy): Change return value to void.
2015-07-06gdb: tui_win_name: Make parameter and result const.Andrew Burgess3-4/+11
This commit makes the parameter and the result for 'tui_win_name' constant. There's one place in the code that is then updated as a result of this change. gdb/ChangeLog: * tui/tui-data.c (tui_partial_win_by_name): Window name is const. (tui_win_name): Make parameter and result const. * tui/tui-data.h (tui_win_name): Make parameter and result const.
2015-07-06Don't throw an error in "show mpx bound" implementationPatrick Palka2-5/+20
"show" functions should not throw an exception in part because it causes the output of the commands "info set" and "show" to get truncated. This fixes the following fails: FAIL: gdb.base/default.exp: info set FAIL: gdb.base/default.exp: show gdb/ChangeLog: * i386-tdep.c (i386_mpx_info_bounds): Don't call error, instead use printf_unfiltered. (set_mpx_cmd): Add missing trailing space to command string literal. (_initialize_i386_tdep): Give the "mpx" prefix command its correct name.

2015-07-03Remove ppc860, ppc750cl, ppc7450 insns from common ppc.Alan Modra10-8/+46
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. Add PPC_OPCODE_7450 to 7450 entry. Add PPC_OPCODE_750 to 750cl entry. gas/ * config/tc-ppc.c (md_show_usage): Add -m821, -m850, -m860. * doc/c-ppc.texi (PowerPC-Opts): Likewise. gas/testsuite/ * gas/ppc/titan.d: Correct mfmcsrr0 disassembly.
2015-07-02Add support for backtracing through Renesas RX exception frames.Kevin Buettner2-21/+265
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'. (rx_analyze_prologue): Add `frame_type' parameter. Cache this parameter in the prologue struct. Add code for recording locations of PC and PSW for fast interrupt and exception frames. (rx_skip_prologue): Adjust call to rx_analyze_prologue. (rx_analyze_frame_prologue): Add `frame_type' parameter. (rx_frame_type): New function. (rx_frame_base): Fetch frame type and pass it to rx_analyze_prologue. (rx_frame_this_id): Rename parameter `this_prologue_cache' to `this_cache'. (rx_frame_prev_register): Rename parameter `this_prologue_cache' to `this_cache'. Add cases for RX_FRAME_TYPE_EXCEPTION and RX_FRAME_TYPE_FAST_INTERRUPT. (normal_frame_p, exception_frame_p, rx_frame_sniffer_common) (rx_frame_sniffer, rx_exception_sniffer): New functions. (rx_frame_unwind): Use rx_frame_sniffer instead of default_frame_sniffer.

2015-07-02rx: Create and use flags types for psw, bpsw, and fpsw registers.Kevin Buettner2-0/+61
This change adds two flags types for the (Renesas RX) psw, bpsw, and fpsw registers. As a result, symbolic flags are displayed for these registers in the output of GDB's "info registers" command as well as in output from other commands, such as "print". gdb/ChangeLog: * rx-tdep.c (RX_BPSW_REGNUM, RX_FPSW_REGNUM): New constants. (struct gdbarch_tdep): Add fields rx_psw_type and rx_fpsw_type. (rx_register_type): Add cases for RX_PSW_REGNUM, RX_BPSW_REGNUM, and RX_FPSW_REGNUM. (rx_gdbarch_init): Initialize PSW, BPSW, and FPSW flags types.

2015-07-01TUI: Make sure to update registers if frame information has changedPatrick Palka4-10/+33
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. Return 1 if frame information has changed, 1 otherwise. (tui_before_prompt): Update commentary. * tui/tui-stack.h (tui_show_frame_info): Change return type to int.

2015-06-30Replace TUI's select_frame hook (PR tui/13378)Patrick Palka5-24/+82
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 ...

2015-06-30Be lazy about refreshing the windows in tui_show_frame_info (PR tui/13378)Patrick Palka2-16/+64
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.
2015-06-30Correctly initialize the TUI locator windowPatrick Palka2-1/+6
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.
