Tom Tromey	5030a410ad	fix some simple thinkos in the test suite This fixes some parallelization thinkos from a while ago. I'm not sure how the problems ever slipped through.

Tom Tromey	95d7853ebb	fix up log-file toggling Currently a proc in gdb.exp toggles the expect (and thus dejagnu) logging. This is not a super idea, but it is there to avoid putting some preprocessor output into the log. In the right circumstances, this can result in the log file being mysteriously truncated. I think this happens because it doesn't necessarily write to the correct log file again. The fix is to use "log_file -info" to save the previous log file. 2013-11-04 Tom Tromey <tromey@redhat.com> * lib/gdb.exp (get_compiler_info): Use log_file -info and restore from that.	13 years ago

Anton Blanchard	67c059c29e	Improve performance of large restore commands I noticed a large (100MB) restore took hours to complete. The problem is memory_xfer_partial repeatedly mallocs and memcpys the entire 100MB buffer for breakpoint shadow handling only to find a small portion of it is actually written.

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.

Ulrich Weigand	055e608a73	S/390: Add missing gdb_prompt in s390-multiarch.exp Correct the patterns in the gdb_test_multiple invocation. testsuite/ 2013-10-30 Andreas Arnez <arnez@linux.vnet.ibm.com> * gdb.arch/s390-multiarch.exp (test_linux_v2): Add $gdb_prompt to the patterns in gdb_test_multiple.	13 years ago
Ulrich Weigand	0e5fae36f1	S/390: Rename source files to -linux- As suggested before, rename the S/390-related source files (tdep and nat) such that "-linux-" occurs in the file name, like with other GNU/Linux targets. Since no other operating system is currently supported by GDB on this architecture, this isn't strictly necessary. But the old names sometimes caused GDB contributors to miss these files when performing a change that affects all GNU/Linux targets. The latest such incident was observed here: https://sourceware.org/ml/gdb-patches/2013-09/msg00619.html gdb/ 2013-10-30 Andreas Arnez <arnez@linux.vnet.ibm.com> * s390-tdep.h: Rename to... * s390-linux-tdep.h: ...here. * s390-tdep.c: Rename to... * s390-linux-tdep.c: ...here.

Andreas Arnez	7d4a7d107a	S/390: Disassemble 31-bit binaries with "zarch" opcode set by default Currently the disassembler for s390 (by default) assumes that a 31-bit binary was compiled in "ESA" mode -- and then only disassembles a limited opcode set. The change upgrades the default to the full "zarch" opcode set even for 31-bit binaries. opcodes/ * s390-dis.c (init_disasm): Default to full 'zarch' opcode availability even for 31-bit programs.	13 years ago
Alan Modra	b4f7960d53	PowerPC64 ELFv2 support for gold. elfcpp/ * powerpc.h (EF_PPC64_ABI): New enum constant. (STO_PPC64_LOCAL_BIT, STO_PPC64_LOCAL_MASK): Likewise.

Alan Modra	e8910a83af	Replace DT_PPC_TLSOPT with DT_PPC_OPT. This removes the DT_PPC_TLSOPT/DT_PPC64_TLSOPT dynamic tag and replaces it with DT_PPC_OPT/DT_PPC64_OPT tag to provide the same functionality and more. This isn't backwards compatible, but the TLSOPT tag hasn't been used since the tls optimisation support was never submitted to glibc. /include/elf/ * ppc.h (DT_PPC_TLSOPT): Delete. (DT_PPC_OPT, PPC_OPT_TLS): Define. * ppc64.h (DT_PPC64_TLSOPT): Delete.

Alan Modra	b9e5796b0d	ELFv2 stub, plt and glink changes An ELFv2 PLT entry is simply the address of the target function rather than three (or two) words to specify entry, toc and static chain. PLT call stubs are correspondingly simpler and need no thread safety barrier. The glink resolver stub and branch table also is simplified, a change that could be applied to ELFv1 too, but isn't as yet. * elf64-ppc.c (PLT_ENTRY_SIZE, PLT_INITIAL_ENTRY_SIZE): Add htab parameter and adjust for ELFv2. Update all uses. (PLT_CALL_STUB_SIZE): Delete. (ppc64_elf_get_synthetic_symtab): Support new glink layout. (allocate_dynrelocs): Likewise. (plt_stub_size, build_plt_stub): Adjust for ELFv2.
