2014-07-26PR 17185Doug Evans5-0/+61
PR 17185 describes a problem with using gdb+guile with libgc 7.4.0. The symptom is a hang in sigsuspend. [The thread referenced in the PR has the details.] It's not clear what the right fix is, or even where the bug is yet. This patch applies the same workaround Guile has applied. There is no functionality or real performance loss with this, and Guile has been using it for awhile. * configure.ac: Add check for header gc/gc.h. Add check for function setenv. * configure: Regenerate. * config.in: Regenerate. * guile/guile.c (_initialize_guile): Add workaround for libgc 7.4.0.

2014-07-25Add a .gitattributes file for use with git-merge-changelogSamuel Bronson2-0/+24
Individual users will still have to: 1. Install git-merge-changelog 2. Set up the merge driver in their git config See gnulib's lib/git-merge-changelog.c [1] for details. For example, I: 1. Patched Debian's gnulib package to build git-merge-changelog, and sent the patch to the Debian maintainer, who then proceeded to not only accept my patch but even write a *manpage* for git-merge-changelog! (Let's hear it for Ian Beckwith.) So now, I can install it simply by running "apt-get install git-merge-changelog". (Except, of course, that I already have it installed from when I was testing my patch.) 2. Did step (2) from .gitattributes With this patch applied and the above two steps done by whatever means you deem best, you can say goodbye to merge conflicts in ChangeLog files -- at least *IF* people stop renaming the danged things, anyway. If you don't do step 2, you will continue to suffer from ChangeLog merge conflicts exactly as before, whether or not you did step 1. If you do step 2 but not step 1, git will likely start complaining that it can't find any "git-merge-changelog" to run. [1]: http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/git-merge-changelog.c [Note: The docs for git-merge-changelog (the comments at the top) say that you need a .gitattributes in every directory. The docs are wrong. Ignore the docs. Well, not the whole docs; just that part. You really only need one at the top level, since .gitattributes uses the same pattern matching rules as .gitignore, which match files in any subdirectory unless you prefix the pattern with a "/", as explained in the gitignore(5) manpage.]
2014-07-25MIPS: Respect the "set mips compression" commandMaciej W. Rozycki2-2/+9
This fixes gdbarch matching, making sure one for the opposite compressed ISA variation is not chosen. That in turn makes "set mips compression" work; right now the setting sticks to the initial value, either inferred from the ELF header of the binary first loaded or the default value if no binary has been used. This only affects debugging with no symbol table available or no binary chosen at all, as otherwise symbol annotations determine the compressed ISA variation. * mips-tdep.c (mips_gdbarch_init): Also check the compressed ISA variation in gdbarch matching.
2014-07-25remove using_exec_ops globalTom Tromey2-21/+17
This removes the using_exec_ops global from exec.c, in favor of querying the target stack directly using target_is_pushed. This is more in keeping with other code in gdb, and is also more future-proof as it is more multi-target-ready. Built and regtested on x86-64 Fedora 20. 2014-07-25 Tom Tromey <tromey@redhat.com> * exec.c (using_exec_ops): Remove. (exec_close_1): Update. Remove extraneous block, reindent.

2014-07-25Always pass signals to the right threadPedro Alves20-79/+716
Currently, GDB can pass a signal to the wrong thread in several different but related scenarios. E.g., if thread 1 stops for signal SIGFOO, the user switches to thread 2, and then issues "continue", SIGFOO is actually delivered to thread 2, not thread 1. This obviously messes up programs that use pthread_kill to send signals to specific threads. This has been a known issue for a long while. Back in 2008 when I made stop_signal be per-thread (2020b7ab), I kept the behavior -- see code in 'proceed' being removed -- wanting to come back to it later. The time has finally come now. The patch fixes this -- on resumption, intercepted signals are always delivered to the thread that had intercepted them. Another example: if thread 1 stops for a breakpoint, the user switches to thread 2, and then issues "signal SIGFOO", SIGFOO is actually delivered to thread 1, not thread 2, because 'proceed' first switches to thread 1 to step over its breakpoint... If the user deletes the breakpoint before issuing "signal FOO", then the signal is delivered to thread 2 (the current thread). "signal SIGFOO" can be used for two things: inject a signal in the program while the program/thread had stopped for none, bypassing "handle nopass"; or changing/suppressing a signal the program had stopped for. These scenarios are really two faces of the same coin, and GDB can't really guess what the user is trying to do. GDB might have intercepted signals in more than one thread even (see the new signal-command-multiple-signals-pending.exp test). At least in the inject case, it's obviously clear to me that the user means to deliver the signal to the currently selected thread, so best is to make the command's behavior consistent and easy to explain. Then, if the user is trying to suppress/change a signal the program had stopped for instead of injecting a new signal, but, the user had changed threads meanwhile, then she will be surprised that with: (gdb) continue Thread 1 stopped for signal SIGFOO. (gdb) thread 2 (gdb) signal SIGBAR ... GDB actually delivers SIGFOO to thread 1, and SIGBAR to thread 2 (with scheduler-locking off, which is the default, because then "signal" or any other resumption command resumes all threads). So the patch makes GDB detect that, and ask for confirmation: (gdb) thread 1 [Switching to thread 1 (Thread 10979)] (gdb) signal SIGUSR2 Note: Thread 3 previously stopped with signal SIGUSR2, User defined signal 2. Thread 2 previously stopped with signal SIGUSR1, User defined signal 1. Continuing thread 1 (the current thread) with specified signal will still deliver the signals noted above to their respective threads. Continue anyway? (y or n) All these scenarios are covered by the new tests.

2014-07-25properly parenthesize two macrosTom Tromey2-2/+8
I happened to notice that a couple of macros in target.h weren't properly using parens and as a result had a strange definition. This patch adds the parens and then fixes the macros to be written as must have been intended. Tested by rebuilding. I'm pushing this as obvious. 2014-07-25 Tom Tromey <tromey@redhat.com> * target.h (target_stopped_data_address) (target_watchpoint_addr_within_range): Use "->", not ".". Fix parentheses.
2014-07-25Clarify the address and pointer conversions on AVR.Pierre Langlois2-5/+18
This patch adds additional comments about the conversion of addresses to pointers and vice-versa on AVR. Special conversion needs to be done when dealing with an address in the flash address space, where both code and read-only data can be stored. Code and data pointers to flash are not addressed the same way: A code pointer is 16 bit addressed. A data pointer is 8 bit addressed, even if the data is in flash. 2014-07-25 Pierre Langlois <pierre.langlois@embecosm.com> * avr-tdep.c (avr_address_to_pointer): Clarify the conversion in the comments. (avr_pointer_to_address): Likewise.
2014-07-25Fix paginate-*.exp racesPedro Alves8-46/+56
Jan pointed out in <https://sourceware.org/ml/gdb-patches/2014-07/msg00553.html> that these testcases have racy results: gdb.base/double-prompt-target-event-error.exp gdb.base/paginate-after-ctrl-c-running.exp gdb.base/paginate-bg-execution.exp gdb.base/paginate-execution-startup.exp gdb.base/paginate-inferior-exit.exp This is easily reproducible with "read1" from: [reproducer for races of expect incomplete reads] http://sourceware.org/bugzilla/show_bug.cgi?id=12649 The '-notransfer -re "<return>" { exp_continue }' trick in the current tests doesn't actually work. The issue that led to the -notransfer trick was that "---Type <return> to continue, or q <return> to quit---" has two "<return>"s. If one wants gdb_test_multiple to not hit the built-in "<return>" match that results in FAIL, one has to expect the pagination prompt in chunks, first up to the first "<return>", then again, up to the second. Something around these lines: gdb_test_multiple "" $test { -re "<return>" { exp_continue } -re "to quit ---" { pass $test } } The intent was for -notransfer+exp_continue to make expect fetch more input, and rerun the matches against the now potentially fuller buffer, and then eventually the -re that includes the full pagination prompt regex would match instead (because it's listed higher up, it would match first). But, once that "<return>" -notransfer -re matches, it keeps re-matching forever. It seems like with exp_continue, expect immediately retries matching, instead of first reading in more data into the buffer, if available. Fix this like I should have done in the first place. There's actually no good reason for gdb_test_multiple to only match "<return>". We can make gdb_test_multiple expect the whole pagination prompt text instead, which is store in the 'pagination_prompt' global (similar to 'gdb_prompt'). Then a gdb_test_multiple caller that doesn't want the default match to trigger, because it wants to see one pagination prompt, does simply: gdb_test_multiple "" $test { -re "$pagination_prompt$" { pass $test } } which is just like when we don't want the default $gdb_prompt match within gdb_test_multiple to trigger, like: gdb_test_multiple "" $test { -re "$gdb_prompt $" { pass $test } } Tested on x86_64 Fedora 20. In addition, I've let the racy tests run all in parallel in a loop for 30 minutes, and they never failed. gdb/testsuite/ 2014-07-25 Pedro Alves <palves@redhat.com> * gdb.base/double-prompt-target-event-error.exp (cancel_pagination_in_target_event): Remove '-notransfer <return>' match.

2014-07-24Remove some GDBSERVER checks from linux-ptraceTom Tromey4-25/+52
This patch removes some GDBSERVER checks from nat/linux-ptrace.c. Currently the code uses a compile-time check to decide whether some flags should be used. This changes the code to instead let users of the module specify an additional set of flags; and then changes gdb's linux-nat.c to call this function. At some later date, when the back ends are fully merged, we will be able to remove this function again. gdb/ 2014-07-24 Tom Tromey <tromey@redhat.com> Gary Benson <gbenson@redhat.com> * nat/linux-ptrace.c (additional_flags): New global.

2014-07-24auto-generate most target debug methodsTom Tromey6-700/+2589
The target debug methods are inconsistently maintained. Most to_* methods have some kind of targetdebug awareness, but not all of them do. The ones that do vary in the quantity and quality of output they generate. This patch changes most of the target debug methods to be automatically generated. All the arguments are printed, and separate lines are printed for entering and existing the outermost call to the target stack. For example now you'd see: -> multi-thread->to_terminal_ours (...) -> multi-thread->to_is_async_p (...) <- multi-thread->to_is_async_p (0x1ebb580) = 1 <- multi-thread->to_terminal_ours (0x1ebb580) -> multi-thread->to_thread_address_space (...) <- multi-thread->to_thread_address_space (0x1ebb580, 26802) = 1 In this case you can see nested calls. The "multi-thread" on the left hand side is the topmost target's shortname. There are some oddities with this patch. I'm on the fence about it all, I really just wrote it on a whim. It's not simple to convert every possible method, since a few don't participate in target delegation. Printing is done by type, so I introduced some new debug-printing-specific typedefs to handle cases where it is nicer to do something else. On the plus side, this lays the groundwork for making targetdebug affect every layer of the target stack. The idea would be to wrap each target_ops in the stack with its own debug_target, and then you could see calls propagate down the stack and back up; I suppose with indentation to make it prettier. (That said there are some gotchas lurking in this idea due to target stack introspection.)

2014-07-24Rationalize "fatal" error handling outside of gdbserverGary Benson5-33/+35
GDB and gdbserver have functions named "fatal" that are used in completely different ways. In gdbserver "fatal" is used to handle critical errors: it differs from "error" in that "fatal" causes gdbserver to exit whereas "error" does not. In GDB "fatal" is used to abort the current operation and return to the command level. This is implemented by throwing a non-error "RETURN_QUIT" exception. This commit removes GDB's "fatal" and "vfatal" functions entirely. The exception-throwing function "throw_vfatal" is renamed as "throw_vquit", and a new convenience function "throw_quit" is added. The small number of calls to "fatal" are replaced with calls to "throw_quit", making what is happening more obvious. This commit also modifies GDB's "throw_error" to call "throw_verror" rather than calling "throw_it" directly. This change means the assignment of RETURN_ERROR as the exception type now happens in precisely one place in GDB rather than two. gdb/ 2014-07-24 Gary Benson <gbenson@redhat.com> * exceptions.h (throw_vfatal): Renamed to...

2014-07-22Remove setting value address for reference entry value target data value.Jan Kratochvil2-9/+5
I cannot reproduce any wrong case having the code removed. I just do not find it correct to have it disabled. But at the same time I do like much / I do not find correct the code myself. It is a bit problematic to have struct value describing a memory content which is no longer present there. What happens there: ------------------------------------------------------------------------------ volatile int vv; static __attribute__((noinline)) int bar (int &ref) { ref = 20; vv++; /* break-here */ return ref; } int main (void) { int var = 10; return bar (var); } ------------------------------------------------------------------------------ <4><c7>: Abbrev Number: 13 (DW_TAG_GNU_call_site_parameter) <c8> DW_AT_location : 1 byte block: 55 (DW_OP_reg5 (rdi)) <ca> DW_AT_GNU_call_site_value: 2 byte block: 91 74 (DW_OP_fbreg: -12) <cd> DW_AT_GNU_call_site_data_value: 1 byte block: 3a (DW_OP_lit10) ------------------------------------------------------------------------------ gdb -ex 'b value_addr' -ex r --args ../gdb ./1 -ex 'watch vv' -ex r -ex 'p &ref@entry' -> 6 return ref; bar (ref=@0x7fffffffd944: 20, ref@entry=@0x7fffffffd944: 10) at 1.C:25 ------------------------------------------------------------------------------ At /* break-here */ struct value variable 'ref' is TYPE_CODE_REF. With FSF GDB HEAD: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $1 = lval_memory (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $3 = 0x7fffffffd944 With your #if0-ed code: (gdb) x/gx arg1.contents 0x6004000a4ad0: 0x00007fffffffd944 (gdb) p ((struct value *)arg1.location.computed.closure).lval $8 = not_lval (gdb) p/x ((struct value *)arg1.location.computed.closure).location.address $9 = 0x0 I do not see how to access ((struct value *)arg1.location.computed.closure).location.address from GDB CLI. Trying (gdb) p &ref@entry will invoke value_addr()'s: if (TYPE_CODE (type) == TYPE_CODE_REF) /* Copy the value, but change the type from (T&) to (T*). We keep the same location information, which is efficient, and allows &(&X) to get the location containing the reference. */ and therefore the address gets fetched already from arg1.contents and not from ((struct value *)arg1.location.computed.closure).location.address . And for any other type than TYPE_CODE_REF this code you removed does not get executed at all. This DW_AT_GNU_call_site_data_value DWARF was meant primarily for Fortran but with -O0 entry values do not get produced and with -Og and higher Fortran always optimizes out the passing by reference. If you do not like the removed code there I am OK with removing it as I do not know how to make it's use reproducible for user anyway. In the worst case - if there really is some way how to exploit it - one should just get Attempt to take address of value not located in memory. instead of some wrong value and it may be easy to fix then. gdb/ 2014-07-22 Jan Kratochvil <jan.kratochvil@redhat.com> * dwarf2loc.c (value_of_dwarf_reg_entry): Remove setting value address for reference entry value target data value.
