Alan Modra	c7c3f80e9c	Assorted x86 testsuite fixes. I think HJ has already fixed the binutils and ld tests with his 2013-09-27 readelf change, but this allows them to pass with wider address output as per Nick's 2013-09-12 readelf change. binutils/testsuite/ * binutils-all/x86-64/compressed-1a.d: Allow wide display of addresses. gas/testsuite/ * gas/cfi/cfi-x86_64.d: Match when lacking end of section padding. ld/testsuite/ * ld-pe/cfi.d: Allow wide display of addresses.	13 years ago

Alan Modra	8b974ba3e8	Simplify ppc64 code setting toc_off. Every function has a nominal toc pointer value, even if it isn't used, so set toc_off for every code section to the value used in that object file. The thinking here was that if a code section didn't use the toc it could use the previous object file's toc pointer value. It can, but doing so is only a gain if functions in that section are called mostly from previous objects sharing the same toc. We lose if the functions in question are called mostly from the current object or following objects, and it's a good bet they will probably mostly be called from the current object. * elf64-ppc.c (ppc64_elf_next_input_section): Always set toc_off to value for object file.	13 years ago

Tiago Stürmer Daitx	0569175e8e	breakpoint.c: fix libc probe scan when no get_longjmp_target exists. As discussed on the GDB ML[1], libc probes for longjmp were not being loaded if a custom <arch>_get_longjmp_target function was not implemented. This is trivially fixed by moving the 'if (!gdbarch_get_longjmp_target_p (gdbarch))' down, just bellow libc probe code and above the per-objfile cache lookup. While the condition could also be removed altogether with no side-effects, it is in fact an optimization to avoid searching for symbols if the arch doesn't provide support for get_longjmp_target(). This has been tested on PPC and PPC64.

Pedro Alves	b18e90f549	infrun.c: use GDB_SIGNAL_0 when hidding signals, not GDB_SIGNAL_TRAP. IMO, it doesn't make sense to map random syscall, fork, etc. events to GDB_SIGNAL_TRAP, and possible have the debuggee see that trap. This just seems conceptually wrong to me - these aren't real signals a debuggee would ever see. In fact, when stopped for those events, on Linux, the debuggee isn't in a signal-stop -- there's no way to resume-and-deliver-signal at that point, for example. E.g., when stopped at a fork event: (gdb) catch fork Catchpoint 2 (fork) (gdb) c Continuing. Catchpoint 2 (forked process 4570), 0x000000323d4ba7c4 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131 131 pid = ARCH_FORK (); (gdb) set debug infrun 1 (gdb) signal SIGTRAP Continuing with signal SIGTRAP. infrun: clear_proceed_status_thread (process 4566) infrun: proceed (addr=0xffffffffffffffff, signal=5, step=0) infrun: resume (step=0, signal=5), trap_expected=0, current thread [process 4566] at 0x323d4ba7c4 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 4566 [process 4566], infrun: status->kind = exited, status = 0 infrun: infwait_normal_state infrun: TARGET_WAITKIND_EXITED [Inferior 1 (process 4566) exited normally] infrun: stop_stepping (gdb) Note the signal went nowhere. It was swallowed. Resuming with a SIGTRAP from a syscall event does queue the signal, but doesn't deliver it immediately, like "signal SIGTRAP" from a real signal would. It's still an artificial SIGTRAP: (gdb) catch syscall Catchpoint 2 (any syscall) (gdb) c Continuing. Catchpoint 2 (call to syscall clone), 0x000000323d4ba7c4 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131 131 pid = ARCH_FORK (); (gdb) set debug infrun 1 (gdb) signal SIGTRAP Continuing with signal SIGTRAP. infrun: clear_proceed_status_thread (process 4622) infrun: proceed (addr=0xffffffffffffffff, signal=5, step=0) infrun: resume (step=0, signal=5), trap_expected=0, current thread [process 4622] at 0x323d4ba7c4 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 4622 [process 4622], infrun: status->kind = exited syscall infrun: infwait_normal_state infrun: TARGET_WAITKIND_SYSCALL_RETURN infrun: syscall number = '56' infrun: BPSTAT_WHAT_STOP_NOISY infrun: stop_stepping Catchpoint 2 (returned from syscall clone), 0x000000323d4ba7c4 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131 131 pid = ARCH_FORK (); (gdb) c Continuing. infrun: clear_proceed_status_thread (process 4622) infrun: proceed (addr=0xffffffffffffffff, signal=144, step=0) infrun: resume (step=0, signal=0), trap_expected=0, current thread [process 4622] at 0x323d4ba7c4 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 4622 [process 4622], infrun: status->kind = stopped, signal = SIGTRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4ba7c4 infrun: random signal 5 Program received signal SIGTRAP, Trace/breakpoint trap. infrun: stop_stepping 0x000000323d4ba7c4 in __libc_fork () at ../nptl/sysdeps/unix/sysv/linux/fork.c:131 131 pid = ARCH_FORK (); (gdb) In all the above, I used 'signal SIGTRAP' to emulate 'handle SIGTRAP pass'. As described in "keep_going", 'handle SIGTRAP pass' does have its place: /* Do not deliver GDB_SIGNAL_TRAP (except when the user explicitly specifies that such a signal should be delivered to the target program). Typically, that would occur when a user is debugging a target monitor on a simulator: the target monitor sets a breakpoint; the simulator encounters this breakpoint and halts the simulation handing control to GDB; GDB, noting that the stop address doesn't map to any known breakpoint, returns control back to the simulator; the simulator then delivers the hardware equivalent of a GDB_SIGNAL_TRAP to the program being debugged. / ... and I've made use of that myself when implementing/debugging stubs/monitors. But in these cases, treating these events as SIGTRAP possibly injects signals in the debuggee they'd never see otherwise, because you need to use ptrace to enable these special events, which aren't real signals. There's more. Take this bit of handle_inferior_event, where we determine whether a real signal (TARGET_WAITKIND_STOPPED) was random or not: if (ecs->event_thread->suspend.stop_signal == GDB_SIGNAL_TRAP) ecs->random_signal = !((bpstat_explains_signal (ecs->event_thread->control.stop_bpstat, GDB_SIGNAL_TRAP) != BPSTAT_SIGNAL_NO) \|\| stopped_by_watchpoint \|\| ecs->event_thread->control.trap_expected \|\| (ecs->event_thread->control.step_range_end && (ecs->event_thread->control.step_resume_breakpoint == NULL))); else { enum bpstat_signal_value sval; sval = bpstat_explains_signal (ecs->event_thread->control.stop_bpstat, ecs->event_thread->suspend.stop_signal); ecs->random_signal = (sval == BPSTAT_SIGNAL_NO); if (sval == BPSTAT_SIGNAL_HIDE) ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_TRAP; } Note that the if (sval == BPSTAT_SIGNAL_HIDE) ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_TRAP; bit is only reacheable for signals != GDB_SIGNAL_TRAP. AFAICS, sval can only be BPSTAT_SIGNAL_HIDE if nothing in the bpstat returns BPSTAT_SIGNAL_PASS. So that excludes a "catch signal" for the signal in question in the bpstat. All other catchpoints that aren't based on breakpoints behind the scenes call process_event_stop_test directly (don't pass through here) (well, almost all: TARGET_WAITKIND_LOADED does have a fall through, but only for STOP_QUIETLY or STOP_QUIETLY_NO_SIGSTOP, which still return before this code is reached). Catchpoints that are implemented as breakpoints behind the scenes can only appear in the bpstat if the signal was GDB_SIGNAL_TRAP (bkpt_breakpoint_hit returns false otherwise). So that leaves a target reporting a hardware watchpoint hit with a signal other than GDB_SIGNAL_TRAP. And even then it looks quite wrong to me to magically convert the signal into a GDB_SIGNAL_TRAP here too -- if the user has set SIGTRAP to "handle pass", the program will see a trap that gdb invented, not one the program would ever see without gdb in the picture. Tested on x86_64 Fedora 17. gdb/ 2013-10-31 Pedro Alves <palves@redhat.com> infrun.c (handle_syscall_event): Don't set or clear stop_signal. (handle_inferior_event) <TARGET_WAITKIND_FORKED, TARGET_WAITKIND_VFORKED>: Don't set stop_signal to GDB_SIGNAL_TRAP, or clear it. Pass GDB_SIGNAL_0 to bpstat_explains signal, instead of GDB_SIGNAL_TRAP. <bpstat handling>: If the bpstat chain wants the signal to be hidden, then set stop_signal to GDB_SIGNAL_0 instead of GDB_SIGNAL_TRAP.	13 years ago

Alan Modra	f9c6b9078c	Report overflow on PowerPC64 @h and @ha relocations. This changes the behaviour of @h and @ha on PowerPC64 to report errors on 32-bit overflow. The motivation for this change is that on PowerPC64, most uses of @h and @ha modifiers and their corresponding relocations are to build up 32-bit offsets. We'd like to know when such offsets overflow. Only rarely do people use @h or @ha with the high 32-bit modifiers to build a 64-bit constant. Those uses will now need to use two new modifiers, @high and @higha, if the constant isn't known at assembly time. For now, we won't report overflow at assembly time.. This also fixes an error when applying some of the HIGHER and HIGHEST relocations. include/elf/ * ppc64.h (R_PPC64_ADDR16_HIGH, R_PPC64_ADDR16_HIGHA, R_PPC64_TPREL16_HIGH, R_PPC64_TPREL16_HIGHA, R_PPC64_DTPREL16_HIGH, R_PPC64_DTPREL16_HIGHA): New.

Jan Beulich	34a79995c4	ld/ELF: refine fake STT_FILE symbol emission There's no real need to emit these always: They're needed only if we indeed want to emit a localized symbol. Hence defer emission until we at least did the basic early checks that would lead to no such symbol getting emitted. This in particular avoids emitting such a symbol in the majority of (if not all) "ld -r" cases.

Tom Tromey	aee17e424f	undef reg in gdb_curses.h I tried to build gdb on the AIX machine in the GCC compile farm (gcc111), but it failed in a couple of spots because gdb uses "reg" as a variable name and the AIX <curses.h> defines "reg" to "register". I saw that we already had a workaround for this lurking in utils.c, so I just moved that to gdb_curses.h.

Yao Qi	487ad57ccf	Simplify REGISTRY cleanup usages In registry.c:registry_clear_data, the registered data is iterated and invoke each 'free' function with the data passed: for (registration = data_registry->registrations, i = 0; i < fields->num_data; registration = registration->next, i++) if (fields->data[i] != NULL && registration->data->free != NULL) adaptor (registration->data->free, container, fields->data[i]); we can see that data is passed to function 'free' and data is not NULL.
