2013-09-18When reverse-stepping, only insert a resume breakpoint at ecs->stop_func_startMarkus Metzger1-1/+1
if the function start is known. Otherwise, keep single-stepping.
2013-09-17PR gdb/15911: "info threads" changes the default source and line (for ↵Pedro Alves1-1/+1
"break", "list") "info threads" changes the default source for "break" and "list", to whatever the location of the first/bottom thread in the thread list is... (gdb) b start (gdb) c ...

Now the call in question, from within thread.c:print_thread_info, does pass in LOCATION as print_what, but print_stack_frame doesn't have the same check print_frame_info has. We could consider adding it, but setting these globals depending on print_what isn't very clean, IMO. What we have is two logically distinct operations mixed in the same function(s): #1 - print frame, in the format specified by {print_what, print_level and print_args}. #2 - We're displaying a frame to the user, and I want the default sal to point here, because the program stopped here, or the user did some context-changing command (up, down, etc.). So I added a new parameter to print_stack_frame & friends for point #2, and went through all calls in the tree adjusting as necessary.

2013-06-27Move comment on the 'stepping over resolver' mechanism to the internals manual.Pedro Alves1-40/+0
This whole comment is now a bit out of place. I looked into moving it to handle_inferior_event, close to where in_solib_dynsym_resolve_code is used, but then there are 3 such places. I then looked at fragmenting it, pushing bits closer to the definitions of in_solib_dynsym_resolve_code and gdbarch_skip_solib_resolver, but then we'd lose the main advantage which is the overview. In the end, I realized this can fit nicely as internals manual material. This could possibly be a subsection of a new "run control", or "source stepping" or "stepping" or some such a bit more general section, but we can do that when we have more related content... Even the "single stepping" section is presently empty... gdb/doc/ 2013-06-27 Pedro Alves <palves@redhat.com> * gdbint.texinfo (Algorithms) <Stepping over runtime loader dynamic symbol resolution code>: New section, based on infrun.c comment. gdb/ 2013-06-27 Pedro Alves <palves@redhat.com> * infrun.c: Remove comment describing the 'stepping over runtime loader dynamic symbol resolution code' mechanism; moved to gdbint.texinfo.

2013-06-18Fix PR cli/15603Tom Tromey1-6/+12
This fixes PR cli/15603. The bug here is that when a software watchpoint is being used, gdb will stop responding to C-c. This is a regression caused by the "catch signal" patch. The problem is that software watchpoints always end up on the bpstat list. However, this makes bpstat_explains_signal return BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a "random signal". The fix is to change bpstat_explains_signal to handle this better. I chose to do it in a "clean API" way, by passing the signal value to bpstat_explains_signal and then adding an explains_signal method for watchpoints, which handles the specifics. Built and regtested on x86-64 Fedora 18. New test case included. * break-catch-sig.c (signal_catchpoint_explains_signal): Add 'sig' argument. * breakpoint.c (bpstat_explains_signal): Add 'sig' argument.

2013-05-23range stepping: gdbPedro Alves1-0/+33
This patch teaches GDB to take advantage of target-assisted range stepping. It adds a new 'r ADDR1,ADDR2' action to vCont (vCont;r), meaning, "step once, and keep stepping as long as the thread is in the [ADDR1,ADDR2) range". Rationale: When user issues the "step" command on the following line of source, a = b + c + d * e - a; GDB single-steps every single instruction until the program reaches a new different line. E.g., on x86_64, that line compiles to: 0x08048434 <+65>: mov 0x1c(%esp),%eax 0x08048438 <+69>: mov 0x30(%esp),%edx 0x0804843c <+73>: add %eax,%edx 0x0804843e <+75>: mov 0x18(%esp),%eax 0x08048442 <+79>: imul 0x2c(%esp),%eax 0x08048447 <+84>: add %edx,%eax 0x08048449 <+86>: sub 0x34(%esp),%eax 0x0804844d <+90>: mov %eax,0x34(%esp) 0x08048451 <+94>: mov 0x1c(%esp),%eax and the following is the RSP traffic between GDB and GDBserver: --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3c840408;thread:p2e13.2e13;core:1; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3e840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:42840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:47840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:49840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:4d840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2e13.2e13;core:0; IOW, a lot of roundtrips between GDB and GDBserver. If we add a new command to the RSP, meaning "keep stepping and don't report a stop until the program goes out of the [0x08048434, 0x08048451) address range", then the RSP traffic can be reduced down to: --> vCont;r8048434,8048451:p2db0.2db0;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2db0.2db0;core:1; As number of packets is reduced dramatically, the performance of stepping source lines is much improved. In case something is wrong with range stepping on the stub side, the debug info or even gdb, this adds a "set/show range-stepping" command to be able to turn range stepping off. gdb/ 2013-05-23 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_control_state) <may_range_step>: New field. * infcmd.c (step_once, until_next_command): Enable range stepping. * infrun.c (displaced_step_prepare): Disable range stepping.

2013-03-13Constify strings in tracepoint.c, lookup_cmd and the completers.Pedro Alves1-1/+1
This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

2012-08-16Change detach_breakpoints to take a ptid instead of a pidJoel Brobecker1-3/+1
Before this change, detach_breakpoints would take a pid, and then set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid). Unfortunately, this ptid is not necessarily valid. Consider for instance the case of ia64-hpux, where ttrace refuses a register-read operation if the LWP is not provided. This problems shows up when GDB is trying to handle fork events. Assuming GDB is configured to follow the parent, GDB will try to detach from the child. But before doing so, it needs to remove all breakpoints inside that child. On ia64, this involves reading inferior (the child's) memory. And on ia64-hpux, reading memory requires us to read the bsp and bspstore registers, in order to determine where that memory is relative to the value of those registers, and thus to determine which ttrace operation to use in order to fetch that memory (see ia64_hpux_xfer_memory). This patch therefore changes detach_breakpoints to take a ptid instead of a pid, and then updates all callers. One of the consequences of this patch is that it trips an assert on GNU/Linux targets. But this assert appears to have not actual purpose, and is thus removed. gdb/ChangeLog: * breakpoint.h (detach_breakpoints): pid parameter is now a ptid. * breakpoint.c (detach_breakpoints): Change pid parameter into a ptid. Adjust code accordingly. * infrun.c (handle_inferior_event): Delete variable child_pid. Update call to detach_breakpoints to pass the child ptid for fork events. * linux-nat.c (linux_nat_iterate_watchpoint_lwps): Remove assert that inferior_ptid's lwp is zero. (linux_handle_extended_wait): Update call to detach_breakpoints. * inf-ttrace.c (inf_ttrace_follow_fork): Update call to detach_breakpoints.
