2020-10-22gdb: make target_ops::make_corefile_notes return a unique ptrSimon Marchi1-43/+45
Since we converted gdbarch_make_corefile_notes to returning a gdb::unique_xmalloc_ptr, I figured it would make sense to converted target_ops::make_corefile_notes as well. The only implementation of that is in procfs.c, and it should ideally be re-written as a gdbarch method (see comment in write_gcore_file_1), but in the mean time I guess it doesn't hurt to throw some unique pointer at it. I tested that it builds on Solaris 11 (gcc compile farm machine gcc211), but I am not able to test it, because I can't get GDB to start a process (I'll look at that separately). gdb/ChangeLog: * target.h (struct target_ops) <make_corefile_notes>: Change return type to unique pointer. * target.c (dummy_make_corefile_notes): Likewise. * exec.c (struct exec_target) <make_corefile_notes>: Likewise.

2020-10-02gdb: fix some inferior_created observer signaturesSimon Marchi1-9/+0
I just noticed that in a7aba2668a7b ("gdb: remove arguments from inferior_created observable"), I forgot to update aix_thread_inferior_created and procfs_inferior_created, which are in files I can't compile. Remove the parameters from aix_thread_inferior_created. And simply remove procfs_inferior_created, since it's empty anyway. gdb/ChangeLog: * aix-thread.c (aix_thread_inferior_created): Remove parameters. * procfs.c (procfs_inferior_created): Remove. (_initialize_procfs): Don't register procfs_inferior_created. Change-Id: Ifc7def7c096332033b5d466d32cb873d1df18c2c

2020-09-18Make target_wait options use enum flagsTom Tromey1-2/+2
This changes TARGET_WNOHANG to be a member of an enum, rather than a define, and also adds a DEF_ENUM_FLAGS_TYPE for this type. Then, it changes target_wait and the various target wait methods to use this type rather than "int". This didn't catch any bugs, but it seems like a decent cleanup nevertheless. I did not change deprecated_target_wait_hook, since that's only used out-of-tree (by Insight), and there didn't seem to be a need. I can't build some of these targets, so I modified them on a best-effort basis. I don't think this patch should go in before the release branch is made. gdb/ChangeLog 2020-09-18 Tom Tromey <tromey@adacore.com> * windows-nat.c (struct windows_nat_target) <wait>: Update.

2020-07-30Unify Solaris procfs and largefile handlingRainer Orth1-2/+0
GDB currently doesn't build on 32-bit Solaris: * On Solaris 11.4/x86: In file included from /usr/include/sys/procfs.h:26, from /vol/src/gnu/gdb/hg/master/dist/gdb/i386-sol2-nat.c:24: /usr/include/sys/old_procfs.h:31:2: error: #error "Cannot use procfs in the large file compilation environment" #error "Cannot use procfs in the large file compilation environment" ^~~~~ * On Solaris 11.3/x86 there are several more instances of this. The interaction between procfs and large-file support historically has been a royal mess on Solaris: * There are two versions of the procfs interface: ** The old ioctl-based /proc, deprecated and not used any longer in either gdb or binutils. ** The `new' (introduced in Solaris 2.6, 1997) structured /proc. * There are two headers one can possibly include: ** <procfs.h> which only provides the structured /proc, definining _STRUCTURED_PROC=1 and then including ... ** <sys/procfs.h> which defaults to _STRUCTURED_PROC=0, the ioctl-based /proc, but provides structured /proc if _STRUCTURED_PROC == 1. * procfs and the large-file environment didn't go well together: ** Until Solaris 11.3, <sys/procfs.h> would always #error in 32-bit compilations when the large-file environment was active (_FILE_OFFSET_BITS == 64). ** In both Solaris 11.4 and Illumos, this restriction was lifted for structured /proc. So one has to be careful always to define _STRUCTURED_PROC=1 when testing for or using <sys/procfs.h> on Solaris. As the errors above show, this isn't always the case in binutils-gdb right now. Also one may need to disable large-file support for 32-bit compilations on Solaris. config/largefile.m4 meant to do this by wrapping the AC_SYS_LARGEFILE autoconf macro with appropriate checks, yielding ACX_LARGEFILE. Unfortunately the macro doesn't always succeed because it neglects the _STRUCTURED_PROC part. To make things even worse, since GCC 9 g++ predefines _FILE_OFFSET_BITS=64 on Solaris. So even if largefile.m4 deciced not to enable large-file support, this has no effect, breaking the gdb build. This patch addresses all this as follows: * All tests for the <sys/procfs.h> header are made with _STRUCTURED_PROC=1, the definition going into the various config.h files instead of having to make them (and sometimes failing) in the affected sources. * To cope with the g++ predefine of _FILE_OFFSET_BITS=64, -U_FILE_OFFSET_BITS is added to various *_CPPFLAGS variables. It had been far easier to have just #undef _FILE_OFFSET_BITS in config.h, but unfortunately such a construct in config.in is commented by config.status irrespective of indentation and whitespace if large-file support is disabled. I found no way around this and putting the #undef in several global headers for bfd, binutils, ld, and gdb seemed way more invasive. * Last, the applicability check in largefile.m4 was modified only to disable largefile support if really needed. To do so, it checks if <sys/procfs.h> compiles with _FILE_OFFSET_BITS=64 defined. If it doesn't, the disabling only happens if gdb exists in-tree and isn't disabled, otherwise (building binutils from a tarball), there's no conflict. What initially confused me was the check for $plugins here, which originally caused the disabling not to take place. Since AC_PLUGINGS does enable plugin support if <dlfcn.h> exists (which it does on Solaris), the disabling never happened. I could find no explanation why the linker plugin needs large-file support but thought it would be enough if gld and GCC's lto-plugin agreed on the _FILE_OFFSET_BITS value. Unfortunately, that's not enough: lto-plugin uses the simple-object interface from libiberty, which includes off_t arguments. So to fully disable large-file support would mean also disabling it in libiberty and its users: gcc and libstdc++-v3. This seems highly undesirable, so I decided to disable the linker plugin instead if large-file support won't work. The patch allows binutils+gdb to build on i386-pc-solaris2.11 (both Solaris 11.3 and 11.4, using GCC 9.3.0 which is the worst case due to predefined _FILE_OFFSET_BITS=64). Also regtested on amd64-pc-solaris2.11 (again on Solaris 11.3 and 11.4), x86_64-pc-linux-gnu and i686-pc-linux-gnu. config: * largefile.m4 (ACX_LARGEFILE) <sparc-*-solaris*|i?86-*-solaris*>: Check for <sys/procfs.h> incompatilibity with large-file support on Solaris.

When a vfork(2) is executed by a traced process, all watched areas established for the parent are suspended until the child terminates or performs an exec(2). Any watched areas established independently in the child are cancelled when the parent resumes after the child's termination or exec(2). PCWATCH fails with EBUSY if applied to the parent of a vfork(2) before the child has terminated or performed an exec(2). The PR_VFORKP flag is set in the pstatus structure for such a parent process. In that situation, the parent cannot be killed even with SIGKILL (as runtest will attempt once the timeout occurs; the pending signal can be seen in the pflags output above), so the whole test hangs until one manually kills the child process. Fortunately, there's an easy way out: when using fork instead of vfork, the problem doesn't occur, and this is what the current patch does: it calls fork_inferior with a dummy pre_trace_fun arg. Tested on amd64-pc-solaris2.11 and sparcv9-sun-solaris2.11. * procfs.c (procfs_pre_trace): New function. (procfs_target::create_inferior): Pass it to fork_inferior.
2020-06-22Solaris, target_wait(), don't rely on inferior_ptidPedro Alves1-28/+17
Debugging on Solaris is broken, with the procfs target backend failing with: procfs: couldn't find pid 0 in procinfo list. as soon as you start a program. The problem is procfs_target::wait assuming that inferior_ptid is meaningful on entry, but, since the multi-target series, inferior_ptid is null_ptid before we call target_wait, in infrun.c: static ptid_t do_target_wait_1 (inferior *inf, ptid_t ptid, target_waitstatus *status, int options) { ... /* We know that we are looking for an event in the target of inferior INF, but we don't know which thread the event might come from. As such we want to make sure that INFERIOR_PTID is reset so that none of the wait code relies on it - doing so is always a mistake. */ switch_to_inferior_no_thread (inf); This patch tweaks the backend to remove the assumption that inferior_ptid points at something. sol-thread.c (the thread_stratum that sits on top of procfs.c) also has the same issue. Some spots in procfs_target::wait were returning TARGET_WAITKIND_SPURIOUS+inferior_ptid. This commit replaces those with waiting again without returning to the core. This fixes the relying on inferior_ptid, and also should fix the issue discussed here: https://sourceware.org/pipermail/gdb/2020-May/048616.html https://sourceware.org/pipermail/gdb/2020-June/048660.html gdb/ChangeLog: 2020-06-22 Pedro Alves <palves@redhat.com> PR gdb/25939 * procfs.c (procfs_target::wait): Don't reference inferior_ptid.

2020-06-21Various procfs.c cleanupsRainer Orth1-175/+28
While reading through procfs.c, I noticed a couple of cleanup opportunities: * Some comments and code allowed for portability across different targets. Since procfs.c is Solaris-only for some time now, those can go. * Likewise, there were some references to the old ioctl-based /proc left. * The code still allowed for SYS_exec. However, it is no longer present in either Solaris 11.3, 11.4, or Illumos. Checking the OpenSolaris sources, I found that it had already been removed in 2010 well before the Solaris 11 release. * Some blocks of #if 0 code can go: ** References to struct procinfo.{g,fp}regs_dirty which are no longer defined. ** Code handling the PR_ASLWP flag where <sys/procfs.h> has #define PR_ASLWP 0x00000040 /* obsolete flag; never set */ Tested on amd64-pc-solaris2.11. * procfs.c: Cleanup many comments.

The all_inferiors (targ) iterator comes up empty. Going from there, I see that in add_thread_silent m_target_stack = {m_top = file_stratum, m_stack = {0x20190e0 <the_dummy_target>, 0x200b8c0 <exec_ops>, 0x0, 0x0, 0x0, 0x0, 0x0}}} i.e. the_procfs_target is missing compared to the_amd64_linux_nat_target on Linux/x86_64. Moving the push_target call earlier allows debugging to get over the initial assertion failure. I run instead into procfs: couldn't find pid 0 in procinfo list. which is fixed by https://sourceware.org/pipermail/gdb-patches/2020-June/169674.html Both patches tested together on amd64-pc-solaris2.11.

2020-06-18Don't write to inferior_ptid in procfs.cPedro Alves1-10/+8
The inferior_ptid write in procfs_do_thread_registers should be unnecessary because the target_fetch_registers method should (and does) extract the ptid from the regcache. Not tested. gdb/ChangeLog: 2020-06-18 Pedro Alves <palves@redhat.com> * procfs.c (procfs_target::attach): Don't write to inferior_ptid. (procfs_target::detach): Use switch_to_no_thread instead of writing to inferior_ptid directly. (do_attach): Change return type to void. Switch to the added thread. (procfs_target::create_inferior): Switch to the added thread. (procfs_do_thread_registers): Don't write to inferior_ptid.
2020-05-18Remove unused ps_lgetLDT etc. on Solaris/x86 [PR25981]Rainer Orth1-79/+0
As reported in PR build/25981, a future Solaris 11.4 update will soon remove the short i386 register names like SS etc. from <sys/regset.h>. They could leak into user code (e.g. via <signal.h> -> <sys/signal.h> -> <sys/ucontext.h>) and pollute the user namespace. Affected code would have a hard time avoiding the issue: LLVM is one of those. While the short names are required to be present by the i386 psABI, that document only demands that they exist in <ucontext.h>, which is what the upcoming update assures. With this change, in a 64-bit-default configuration, procfs.c fails to compile on Solaris/x86: /vol/src/gnu/gdb/hg/master/git/gdb/procfs.c: In function 'ssd* procfs_find_LDT_entry(ptid_t)': /vol/src/gnu/gdb/hg/master/git/gdb/procfs.c:1643:18: error: 'GS' was not declared in this scope 1643 | key = (*gregs)[GS] & 0xffff; | ^~ make[2]: *** [Makefile:1607: procfs.o] Error 1 Initially I meant to provide a definition using the planned replacement macro, but closer inspection revealed a better way. procfs_find_LDT_entry and its helper proc_get_LDT_entry are only used to implement ps_lgetLDT, one of the callback functions required by libthread_db.so.1 (cf. <proc_service.h>). While that function is still documented as being required even in Solaris 11.4, I found that calls to it had been removed long ago in Solaris 9, so just removing the three functions above is the easiest fix. The following patch does just that. It compiled successfully on amd64-pc-solaris2.11, however, as reported in PR gdb/25939, master is completely broken on Solaris since the multi-target patch. The patch applies cleanly to the gdb-9 branch and there I could test it successfully.

2020-01-13gdb: add back declarations for _initialize functionsSimon Marchi1-1/+2
I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

2020-01-10Multi-target supportPedro Alves1-23/+26
This commit adds multi-target support to GDB. What this means is that with this commit, GDB can now be connected to different targets at the same time. E.g., you can debug a live native process and a core dump at the same time, connect to multiple gdbservers, etc. Actually, the word "target" is overloaded in gdb. We already have a target stack, with pushes several target_ops instances on top of one another. We also have "info target" already, which means something completely different to what this patch does. So from here on, I'll be using the "target connections" term, to mean an open process_stratum target, pushed on a target stack. This patch makes gdb have multiple target stacks, and multiple process_stratum targets open simultaneously. The user-visible changes / commands will also use this terminology, but of course it's all open to debate. User-interface-wise, not that much changes. The main difference is that each inferior may have its own target connection. A target connection (e.g., a target extended-remote connection) may support debugging multiple processes, just as before. Say you're debugging against gdbserver in extended-remote mode, and you do "add-inferior" to prepare to spawn a new process, like: (gdb) target extended-remote :9999 ... (gdb) start ... (gdb) add-inferior Added inferior 2 (gdb) inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] (gdb) file a.out ... (gdb) start ... At this point, you have two inferiors connected to the same gdbserver. With this commit, GDB will maintain a target stack per inferior, instead of a global target stack. To preserve the behavior above, by default, "add-inferior" makes the new inferior inherit a copy of the target stack of the current inferior. Same across a fork - the child inherits a copy of the target stack of the parent. While the target stacks are copied, the targets themselves are not. Instead, target_ops is made a refcounted_object, which means that target_ops instances are refcounted, which each inferior counting for a reference. What if you want to create an inferior and connect it to some _other_ target? For that, this commit introduces a new "add-inferior -no-connection" option that makes the new inferior not share the current inferior's target. So you could do: (gdb) target extended-remote :9999 Remote debugging using :9999 ... (gdb) add-inferior -no-connection [New inferior 2] Added inferior 2 (gdb) inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] (gdb) info inferiors Num Description Executable 1 process 18401 target:/home/pedro/tmp/main * 2 <null> (gdb) tar extended-remote :10000 Remote debugging using :10000 ... (gdb) info inferiors Num Description Executable 1 process 18401 target:/home/pedro/tmp/main * 2 process 18450 target:/home/pedro/tmp/main (gdb) A following patch will extended "info inferiors" to include a column indicating which connection an inferior is bound to, along with a couple other UI tweaks. Other than that, debugging is the same as before. Users interact with inferiors and threads as before. The only difference is that inferiors may be bound to processes running in different machines. That's pretty much all there is to it in terms of noticeable UI changes. On to implementation. Since we can be connected to different systems at the same time, a ptid_t is no longer a unique identifier. Instead a thread can be identified by a pair of ptid_t and 'process_stratum_target *', the later being the instance of the process_stratum target that owns the process/thread. Note that process_stratum_target inherits from target_ops, and all process_stratum targets inherit from process_stratum_target. In earlier patches, many places in gdb were converted to refer to threads by thread_info pointer instead of ptid_t, but there are still places in gdb where we start with a pid/tid and need to find the corresponding inferior or thread_info objects. So you'll see in the patch many places adding a process_stratum_target parameter to functions that used to take only a ptid_t. Since each inferior has its own target stack now, we can always find the process_stratum target for an inferior. That is done via a inf->process_target() convenience method. Since each inferior has its own target stack, we need to handle the "beneath" calls when servicing target calls. The solution I settled with is just to make sure to switch the current inferior to the inferior you want before making a target call. Not relying on global context is just not feasible in current GDB. Fortunately, there aren't that many places that need to do that, because generally most code that calls target methods already has the current context pointing to the right inferior/thread. Note, to emphasize -- there's no method to "switch to this target stack". Instead, you switch the current inferior, and that implicitly switches the target stack. In some spots, we need to iterate over all inferiors so that we reach all target stacks. Native targets are still singletons. There's always only a single instance of such targets. Remote targets however, we'll have one instance per remote connection. The exec target is still a singleton. There's only one instance. I did not see the point of instanciating more than one exec_target object. After vfork, we need to make sure to push the exec target on the new inferior. See exec_on_vfork. For type safety, functions that need a {target, ptid} pair to identify a thread, take a process_stratum_target pointer for target parameter instead of target_ops *. Some shared code in gdb/nat/ also need to gain a target pointer parameter. This poses an issue, since gdbserver doesn't have process_stratum_target, only target_ops. To fix this, this commit renames gdbserver's target_ops to process_stratum_target. I think this makes sense. There's no concept of target stack in gdbserver, and gdbserver's target_ops really implements a process_stratum-like target. The thread and inferior iterator functions also gain process_stratum_target parameters. These are used to be able to iterate over threads and inferiors of a given target. Following usual conventions, if the target pointer is null, then we iterate over threads and inferiors of all targets. I tried converting "add-inferior" to the gdb::option framework, as a preparatory patch, but that stumbled on the fact that gdb::option does not support file options yet, for "add-inferior -exec". I have a WIP patchset that adds that, but it's not a trivial patch, mainly due to need to integrate readline's filename completion, so I deferred that to some other time. In infrun.c/infcmd.c, the main change is that we need to poll events out of all targets. See do_target_wait. Right after collecting an event, we switch the current inferior to an inferior bound to the target that reported the event, so that target methods can be used while handling the event. This makes most of the code transparent to multi-targets. See fetch_inferior_event. infrun.c:stop_all_threads is interesting -- in this function we need to stop all threads of all targets. What the function does is send an asynchronous stop request to all threads, and then synchronously waits for events, with target_wait, rinse repeat, until all it finds are stopped threads. Now that we have multiple targets, it's not efficient to synchronously block in target_wait waiting for events out of one target. Instead, we implement a mini event loop, with interruptible_select, select'ing on one file descriptor per target. For this to work, we need to be able to ask the target for a waitable file descriptor. Such file descriptors already exist, they are the descriptors registered in the main event loop with add_file_handler, inside the target_async implementations. This commit adds a new target_async_wait_fd target method that just returns the file descriptor in question. See wait_one / stop_all_threads in infrun.c. The 'threads_executing' global is made a per-target variable. Since it is only relevant to process_stratum_target targets, this is where it is put, instead of in target_ops. You'll notice that remote.c includes some FIXME notes. These refer to the fact that the global arrays that hold data for the remote packets supported are still globals. For example, if we connect to two different servers/stubs, then each might support different remote protocol features. They might even be different architectures, like e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a host/controller scenario as a single program. That isn't going to work correctly today, because of said globals. I'm leaving fixing that for another pass, since it does not appear to be trivial, and I'd rather land the base work first. It's already useful to be able to debug multiple instances of the same server (e.g., a distributed cluster, where you have full control over the servers installed), so I think as is it's already reasonable incremental progress. Current limitations: - You can only resume more that one target at the same time if all targets support asynchronous debugging, and support non-stop mode. It should be possible to support mixed all-stop + non-stop backends, but that is left for another time. This means that currently in order to do multi-target with gdbserver you need to issue "maint set target-non-stop on". I would like to make that mode be the default, but we're not there yet. Note that I'm talking about how the target backend works, only. User-visible all-stop mode works just fine. - As explained above, connecting to different remote servers at the same time is likely to produce bad results if they don't support the exact set of RSP features.

2019-12-16Constify get_exec_fileTom Tromey1-2/+1
I noticed that get_exec_file could return a "const char *". This patch implements this change. I couldn't build all the code -- but I did build Linux native and a mingw cross. Consequently, the NTO code has a hack, where it casts away const. I think this can be removed, but that required more work there, and since I couldn't compile it, I felt it best not to try.

2019-09-12Fix signals reported for faults on SolarisRainer Orth1-33/+5
It's been a long-standing nuisance that gdb reported unaligned accesses on Solaris/SPARC as SIGSEGV, contrary to the shells and truss which correctly report SIGBUS instead. I could trace this down to the fault handling code in procfs.c (procfs_target::wait): when pr_why is set to PR_FAULTED, the current code sets the signal based on the fault number. For one, the code gets this wrong for FLTACCESS (the unaligned access case) where it uses SIGSEGV. What's worse, it's completely unnecessary to make up the signal number inside gdb. Instead, it should just take what procfs reports to avoid mismatches, which is what this patch does. I've completely removed the explicit handling of the various fault codes: for one, the list has already been incomplete, lacking FLTCPCOVF which existed since at least Solaris 8. Besides, there's no reason to error out on unknown fault codes: either the fault causes a signal which can then be reported from procfs, or it doesn't (as for FLTPAGE) and no reporting is necessary. Tested on sparcv9-sun-solaris2.11 and x86_64-pc-solaris2.11. Also spot-checked manually for a couple of cases (unaligned access, division by 0, NULL pointer dereference). * procfs.c (procfs_target::wait) <PR_FAULTED>: Get signal from prstatus.pr_lwp.pr_info instead of making it up.
2019-07-10Don't include gdbarch.h from defs.hTom Tromey1-1/+1
I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.
2019-07-09Rename common to gdbsupportTom Tromey1-4/+4
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

2019-03-13Change pid_to_str to return std::stringTom Tromey1-18/+13
Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files.

2019-03-05Remove excess calls to gdb_flushTom Tromey1-1/+0
A customer noticed some mildly odd MI output, where CLI output was split into multiple MI strings at unusual boundaries, like this: ~"$1 = (b => true" ~", p => 0x407260" This is technically correct according to the MI spec, but still unusual, in that there's no particular reason for the string to be split where it is. I tracked this down to a call to gdb_flush in generic_val_print. Then, I went through all calls to gdb_flush and removed the ones I thought were superfluous. In particular: * Any call in the value-printing code; * Likewise the type-printing code (just a single call); and * Any call that immediately followed a printf that obviously ended with a newline, my belief being that gdb's standard output streams are line buffered (by inheriting the behavior from stdio) Regression tested on x86-64 Fedora 29. I didn't add a new test case. I tend to think we don't necessarily want to specify this behavior in the tests.

2019-02-28Can't interrupt process without controlling terminal on Solaris (PR gdb/8527)Rainer Orth1-0/+5
If gdb attaches to a process that either has no controlling terminal, or the controlling terminal differs from the one gdb is running under, break/^C doesn't interrupt the debugged process on Solaris. Fixed as follows, analogous to what all all other targets do. Patch from the PR, recently re-submitted by Brian Vandenberg. Tested on amd64-pc-solaris2.11, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu. 2019-02-28 Brian Vandenberg <phantall@gmail.com> Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gdb: PR gdb/8527 * procfs.c (proc_wait_for_stop): Wrap write of PCWSTOP in set_sigint_trap, clear_sigint_trap. gdb/testsuite: PR gdb/8527 * gdb.base/interrupt-daemon-attach.c, gdb.base/interrupt-daemon-attach.exp: New test.

2019-01-24target_pass_signals/target_program_signals: Use gdb::array_viewPedro Alves1-3/+3
This replaces the pointer and length parameters of target_pass_signals and target_program_signals with a gdb::array_view parameter, and fixes the fallout. In infrun.c, the signal_stop, signal_print, signal_program, signal_catch, signal_pass globals are currently pointers to heap-allocated memory. I see no point in that, so I converted them to arrays. This allows simplifying the calls to target_pass_signals/target_program_signals, since we can pass the array directly, which can implicitly convert to gdb::array_view. gdb/ChangeLog: 2019-01-24 Pedro Alves <palves@redhat.com> * infrun.c (signal_stop, signal_print, signal_program) (signal_catch, signal_pass): Now arrays instead of pointers. (update_signals_program_target, do_target_resume) (signal_catch_update, handle_command, _initialize_infrun): Adjust. * linux-nat.c (linux_nat_target::pass_signals) (linux_nat_target::create_inferior, linux_nat_target::attach): Adjust. * linux-nat.h (linux_nat_target::pass_signals): Adjust. * nto-procfs.c (nto_procfs_target::pass_signals): Adjust. * procfs.c (procfs_target::pass_signals): Adjust. * record-full.c (record_full_target::resume): Adjust. * remote.c (remote_target::pass_signals) (remote_target::program_signals): Adjust. * target-debug.h (target_debug_print_signals): Now takes a gdb::array_view as parameter. Adjust. * target.h (target_ops) <pass_signals, program_signals>: Replace pointer and length parameters with gdb::array_view.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

The recent commit 080363310650 ("Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.") removed the definitions of is_running/is_stopped/is_exited but missed updating a couple uses of is_exited in Solaris-specific code. Tested by Rainer Orth on amd64-pc-solaris2.11. gdb/ChangeLog: 2018-11-26 Pedro Alves <palves@redhat.com> * procfs.c (procfs_notice_thread): Replace uses of in_thread_list/is_exited with find_thread_ptid/THREAD_EXITED. * sol-thread.c (sol_thread_target::wait) (sol_update_thread_list_callback): Likewise.

The Solaris build is currently broken: /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c: In member function ‘virtual void procfs_target::create_inferior(const char*, const string&, char**, int)’: /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:3038:28: error: ‘get_shell’ was not declared in this scope const char *shell_file = get_shell (); ^~~~~~~~~ /vol/src/gnu/gdb/hg/master/dist/gdb/procfs.c:3038:28: note: suggested alternative: ‘getusershell’ const char *shell_file = get_shell (); ^~~~~~~~~ getusershell The following patch fixes this. Tested on amd64-pc-solaris2.11. 2018-10-29 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> * procfs.c: Include common/pathstuff.h.
2018-10-27Unify shell-finding logicTom Tromey1-2/+2
I noticed several places in gdb that were using getenv("SHELL") and then falling back to "/bin/sh" if it returned NULL. This unifies these into a single function. gdb/ChangeLog 2018-10-27 Tom Tromey <tom@tromey.com> * procfs.c (procfs_target::create_inferior): Use get_shell. * cli/cli-cmds.c (shell_escape): Use get_shell. * windows-nat.c (windows_nat_target::create_inferior): Use get_shell. * common/pathstuff.c (get_shell): New function. * nat/fork-inferior.c (SHELL_FILE, get_startup_shell): Remove.

2018-09-20More Solaris procfs cleanupRainer Orth1-132/+109
This procfs.c (and friends) cleanup patch grew along a couple of lines: * First I noticed that PR_MODEL_NATIVE is always defined now that Solaris 10 is the minimum supported version. * Then there was a cleanup that I'd missed when removing support for !NEW_PROC_API, IRIX, and Tru64 UNIX: given that sysset_t is no longer dynamic, there's no need for the special sysset_t_alloc, but we can just use XNEW instead. * Then I found one of those ARI warning mails on gdb-patches, discovered how to run it myself and fixed a large number of the warnings, among them all uses of sprintf. I had to silence the warnings in only 3 instances of the same issue, namely references to LDT in function names which are due to the libthread_db API. * Even so, there were several formatting glitches, like braces around single statements in an if, which I chose to fix while I was at it. The result has been tested on amd64-pc-solaris2.11 and amd64-pc-solaris2.11. * proc-utils.h (PROC_CTL_WORD_TYPE): Remove. * procfs.c: Don't check for PR_MODEL_NATIVE definition. * sparc-sol2-nat.c: Likewise.

2018-09-20Provide pid_to_exec_file on Solaris (PR tdep/17903)Rainer Orth1-0/+31
While looking through gdb.log, I found that two tests FAIL like this: warning: No executable has been specified and target does not support determining executable automatically. Try using the "file" command. 0x00400dc4 in ?? () (gdb) FAIL: gdb.base/attach.exp: attach2, with no file The other is gdb.base/quit-live.exp. I've implemented the following patch that fixes both failures, only then detecting that I'd previously reported the issue as PR tdep/17903. Tested on amd64-pc-solaris2.10 and amd64-pc-solaris2.11.

2018-06-07target_stack -> current_top_target() throughoutPedro Alves1-1/+1
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

2018-05-03Convert struct target_ops to C++Pedro Alves1-170/+136
I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

2018-05-03More procfs.c simplificationPedro Alves1-1/+5
There are only two architectures using procfs.c (i386/SPARC), and none of their corresponding nat files overrides any target method. Move the add_target calls to procfs.c directly. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * i386-sol2-nat.c (_initialize_amd64_sol2_nat): Don't call procfs_target/add_target here. * procfs.c (procfs_target): Make static. (_initialize_procfs): Call add_target here. * procfs.h (struct target_ops): Remove forward declaration. (procfs_target): Remove declaration. * sparc-sol2-nat.c (_initialize_sparc_sol2_nat): Delete.
