2013-10-25infrun debug output: print enum gdb_signal symbol names instead of POSIX ↵Pedro Alves2-1/+14
signal names. The other day while debugging something related to random signals, I got confused with "set debug infrun 1" output, for it said: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 On GNU/Linux, 20 is SIGTSTP. For some reason, it took me a few minutes to realize that 20 is actually a GDB signal number, not a target signal number (duh!). In any case, I propose making GDB's output clearer here: One way would be to use gdb_signal_to_name, like already used elsewhere: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal SIGCHLD (20) but I think that might confuse someone too ("20? Why does GDB believe SIGCHLD is 20?"). So I thought of printing the enum string instead: infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal GDB_SIGNAL_CHLD (20) Looking at a more complete infrun debug log, we had actually printed the (POSIX) signal name name a bit before: infrun: target_wait (-1, status) = infrun: 9300 [Thread 0x7ffff7fcb740 (LWP 9300)], infrun: status->kind = stopped, signal = SIGCHLD ... infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x323d4e8b94 infrun: random signal 20 So I'm now thinking that it'd be even better to make infrun output consistently use the enum symbol string, like so: infrun: clear_proceed_status_thread (Thread 0x7ffff7fca700 (LWP 25663)) infrun: clear_proceed_status_thread (Thread 0x7ffff7fcb740 (LWP 25659)) - infrun: proceed (addr=0xffffffffffffffff, signal=144, step=1) + infrun: proceed (addr=0xffffffffffffffff, signal=GDB_SIGNAL_DEFAULT, step=1) - infrun: resume (step=1, signal=0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGCHLD + infrun: status->kind = stopped, signal = GDB_SIGNAL_CHLD infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400700 - infrun: random signal 20 + infrun: random signal (GDB_SIGNAL_CHLD) infrun: random signal, keep going - infrun: resume (step=1, signal=20), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 + infrun: resume (step=1, signal=GDB_SIGNAL_CHLD), trap_expected=0, current thread [Thread 0x7ffff7fcb740 (LWP 25659)] at 0x400700 infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 25659 [Thread 0x7ffff7fcb740 (LWP 25659)], - infrun: status->kind = stopped, signal = SIGTRAP + infrun: status->kind = stopped, signal = GDB_SIGNAL_TRAP infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x400704 infrun: stepi/nexti infrun: stop_stepping GDB's signal numbers are public and hardcoded (see include/gdb/signals.h), so there's really no need to clutter the output with numeric values in some places while others not. Replacing the magic "144" with GDB_SIGNAL_DEFAULT in "proceed"'s debug output (see above) I think is quite nice. I posit that all this makes it clearer to newcomers that GDB has its own signal numbering (and that there must be some mapping going on).

2013-10-25Fix off-by-one errors in *scanf format strings.Gary Benson1-25/+41
In the first hunk, the format string was off-by-one for cmd, and cmd itself was larger than the maximum size required. cmd was reduced in size and the format string adjusted. In the second hunk, the format string was off-by-one for local_address, remote_address and extra, although the buffers for the two addresses were large enough for this not to matter. The specifiers for the two addresses was corrected, and a number of unused variables including extra were suppressed from parsing. In the third hunk, the format string was off-by-one for name, dependencies and status. This code was rewritten using strtok since dependencies can be arbitrarily long. gdb/ 2013-10-23 Gary Benson <gbenson@redhat.com> PR 16013 * common/linux-osdata.c (command_from_pid): Reduced size of cmd from 32 to 18.

2013-10-25Fix up a couple oddities in GDB's signal names and strings.Pedro Alves1-12/+12
- The Mach exception/signals escaped the TARGET_ -> GDB_ prefix change done a while ago, but there's no real reason for that. I grepped for TARGET_EXC and fixed all found, which unsurprisingly, means darwin-nat.c needed fixing. I think the change there is as obvious and trivial as it can get, so I'd be quite surprised if this broke anything there somehow. - GDB_SIGNAL_LAST's description string was unnecessarily inconsistent with the enum name.

2013-10-04Clean up ptid.h/ptid.c.Pedro Alves2-49/+37
The ptid_t contructors, accessors and predicates are documented in _three_ places, and each place uses a different wording. E.g, the descriptions in the .c file of the new ptid_lwp_p, ptid_tid_p weren't updated in the final revision like the descriptions in the .h file were. Clearly, switching to a style that has a single central description avoids such issues. Worse, some of the existing descriptions are plain wrong, such as: /* Attempt to find and return an existing ptid with the given PID, LWP, and TID components. If none exists, create a new one and return that. */ ptid_t ptid_build (int pid, long lwp, long tid); The function does nothing that complicated. It's just a simple constructor. So this gets rid of all the unnecessary descriptions, leaving only the ones near the function declarations in the header file, and fixes/clarifies those that remain. gdb/ 2013-10-04 Pedro Alves <palves@redhat.com> * common/ptid.c (null_ptid, minus_one_ptid, ptid_build) (pid_to_ptid, ptid_get_pid, ptid_get_lwp, ptid_get_tid) (ptid_equal, ptid_is_pid, ptid_lwp_p, ptid_tid_p): Replace describing comments with references to ptid.h. * common/ptid.h: Remove intro description of constructors, accessors and predicates.

2013-10-03Always run the PTRACE_O_TRACESYSGOOD tests even if PTRACE_O_TRACEFORK is not ↵Pedro Alves1-37/+46
supported. If enabling PTRACE_O_TRACEFORK fails, we never test for PTRACE_O_TRACESYSGOOD support. Before PTRACE_O_TRACESYSGOOD is checked, we have: /* First, set the PTRACE_O_TRACEFORK option. If this fails, we know for sure that it is not supported. */ ret = ptrace (PTRACE_SETOPTIONS, child_pid, (PTRACE_TYPE_ARG3) 0, (PTRACE_TYPE_ARG4) PTRACE_O_TRACEFORK); if (ret != 0) { ret = ptrace (PTRACE_KILL, child_pid, (PTRACE_TYPE_ARG3) 0, (PTRACE_TYPE_ARG4) 0); if (ret != 0) { warning (_("linux_check_ptrace_features: failed to kill child")); return; } ret = my_waitpid (child_pid, &status, 0); if (ret != child_pid) warning (_("linux_check_ptrace_features: failed " "to wait for killed child")); else if (!WIFSIGNALED (status)) warning (_("linux_check_ptrace_features: unexpected " "wait status 0x%x from killed child"), status); return; <<<<<<<<<<<<<<<<< } Note that early return. If PTRACE_O_TRACEFORK isn't supported, we're not checking PTRACE_O_TRACESYSGOOD. This didn't use to be a problem before the unification of this whole detection business in linux-ptrace.c. Before, the sysgood detection was completely separate: static void linux_test_for_tracesysgood (int original_pid) { int ret; sigset_t prev_mask; /* We don't want those ptrace calls to be interrupted. */ block_child_signals (&prev_mask); linux_supports_tracesysgood_flag = 0; ret = ptrace (PTRACE_SETOPTIONS, original_pid, 0, PTRACE_O_TRACESYSGOOD); if (ret != 0) goto out; linux_supports_tracesysgood_flag = 1; out: restore_child_signals_mask (&prev_mask); } So we need to get back the decoupling somehow. I think it's cleaner to split the seperate feature detections to separate functions. This patch does that. The new functions are named for their counterparts that existed before this code was moved to linux-ptrace.c. Note I've used forward declarations for the new functions to make the patch clearer, as otherwise the patch would look like I'd be adding a bunch of new code. A reorder can be done in a follow up patch. Tested on x86_64 Fedora 17. gdb/ 2013-10-03 Pedro Alves <palves@redhat.com> * common/linux-ptrace.c (linux_check_ptrace_features): Factor out the PTRACE_O_TRACESYSGOOD and PTRACE_O_TRACEFORK to separate functions.

(linux_test_for_tracefork): New function, factored out from linux_check_ptrace_features, and also don't kill child_pid here.

2013-09-29gdb: btrace: fix build errors on older glibc buildsMike Frysinger1-2/+5
It is possible to have a build of glibc where SYS_perf_event_open is not defined (because when the glibc was compiled, the syscall did not exist), but have newer kernel headers installed so that linux/perf_event.h is available. In this setup, you get a build failure: ./common/linux-btrace.c: In function 'kernel_supports_btrace': ./common/linux-btrace.c:316:23: error: 'SYS_perf_event_open' undeclared (first use in this function) Update the ifdef check to also see if the syscall is available.

2013-06-24Fix host_name and target_name generation by common/create-version.sh.Joel Brobecker1-2/+2
This new script has one small snafoo, which prevented the $host_alias and $target_alias from being expanded during the generation of the version.c file. As a result, the version info yields: This GDB was configured as "--host=$host_alias --target=$target_alias". ^^^^^^^^^^^ ^^^^^^^^^^^^^ This patch fixes this issue. gdb/ChangeLog: * common/create-version.sh: Fix expansion of $host_alias and $target_alias in generation of HOST_NAME and TARGET_NAME (resp.).
2013-06-24don't keep a gdb-specific dateTom Tromey3-0/+70
Right now there are two nightly commits to update a file in the tree with the current date. One commit is for BFD, one is for gdb. It seems unnecessary to me to do this twice. We can make do with a single such commit. This patch changes gdb in a minimal way to reuse the BFD date -- it extracts it from bfd/version.h and changes version.in to use the placeholder string "DATE" for those times when a date is wanted. I propose removing the cron job that updates the version on trunk, and then check in this patch. For release branches, we can keep the cron job, but just tell it to rewrite bfd/version.h. I believe this is a simple change in the crontab -- the script will work just fine on this file. This also moves version.in and version.h into common/, to reflect their shared status; and updates gdbserver to use version.h besides. * common/create-version.sh: New file. * Makefile.in (version.c): Use bfd/version.h, common/version.in, create-version.sh.

2013-06-19gdb: clean up x86 cpuid implementationsMike Frysinger3-31/+345
We've currently got 3 files doing open coded implementations of cpuid. Each has its own set of workarounds and varying levels of how well they're written and are generally hardcoded to specific cpuid functions. If you try to build the latest gdb as a PIE on an i386 system, the build will fail because one of them lacks PIC workarounds (wrt ebx). Specifically, we have: common/linux-btrace.c: two copies of cpuid asm w/specific args, one has no workarounds while the other implicitly does to avoid memcpy go32-nat.c: two copies of cpuid asm w/specific args, one has workarounds to avoid memcpy gdb/testsuite/gdb.arch/i386-cpuid.h: one general cpuid asm w/many workarounds copied from older gcc Fortunately, that last header there is pretty damn good -- it handles lots of edge cases, the code is nice & tight (uses gcc asm operands rather than manual movs), and is already almost a general library type header. It's also the basis of what is now the public cpuid.h that is shipped with gcc-4.3+. So what I've done is pull that test header out and into gdb/common/ (not sure if there's a better place), synced to the version found in gcc-4.8.0, put a wrapper API around it, and then cut over all the existing call points to this new header. Since the func already has support for "is cpuid supported on this proc", it makes it trivial to push the i386/x86_64 ifdefs down into this wrapper API too. Now it can be safely used for all targets and gcc will elide the unused code for us. I've verified the gdb.arch testsuite still passes, and this code compiles for an armv7a host as well as x86_64. The go32-nat code has been left ifdef-ed out until someone can test & verify the new stuff works (and if it doesn't, figure out how to make the new code work).
