2013-10-01[gdbserver/LynxOS]: Incomplete thread list after --attachJoel Brobecker2-1/+43
The current implementation is forgetting to populate the thread list when attaching to the process. This results in an incomplete list of threads when debugging a threaded program. Unfortunately, as the added comments hints, there appears to be no way of getting the list of threads via ptrace, other than by spawning the "ps" command, and parsing its output. Not great, but it appears to be the best we can do. gdb/gdbserver/ChangeLog: * lynx-low.c (lynx_add_threads_after_attach): New function. (lynx_attach): Remove call to add_thread. Add call to lynx_add_threads_after_attach instead.

2013-10-01[ELinOS] Best effort to load system libraries in case of incomplete envJoel Brobecker2-12/+33
So far elinos.py was assuming that the whole ELinOS environment was around to find the system libraries; if some environment variables were missing, the script would just abort. This was a bit extreme. It is possible to do better than that: to get the core system libraries, one doesn't need to have a full environment but just the path to the CDK. The path to kernel project is only needed for the optional Xenomai libs. gdb/ChangeLog: * system-gdbinit/elinos.py (get_elinos_environment): Return an incomplete dictionnary instead of None in case of missing environment variables. (elinos_init): in case of an incomplete environment, best effort to load system libraries instead of abort.
2013-10-01wrong "catch exception" error message when finding trampoline msym.Joel Brobecker2-1/+9
When building the program with the shared GNAT runtime, the debugger is unable to insert Ada exception catchpoints until that runtime has been mapped to memory. In other words, we expect the user to start the program first, before attempting to insert that catchpoint. The detection mechanism that tries to provide some useful tips to the user fails when the program itself contains a trampoline symbol matching the symbol that the catchpoint is trying to use. This results in the following error message: (gdb) catch exception Your Ada runtime appears to be missing some debugging information. Cannot insert Ada exception catchpoint in this configuration. Instead, we expected the following error message: (gdb) catch exception Unable to insert catchpoint. Try to start the program first. gdb/ChangeLog: * ada-lang.c (ada_has_this_exception_support): Ignore mst_solib_trampoline minimal symbols.

2013-09-29gdb: btrace: fix build errors on older glibc buildsMike Frysinger6-4/+21
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.

2013-09-27Fix regular /path/to/directory sysroots and target reported dll paths with ↵Pedro Alves4-3/+40
drive specs. I tried debugging a remote Windows program on Linux host, and pointed the sysroot to "/some/path/" rather than "remote:", and I found GDB couldn't find the dlls in the sysroot. If the dll name is "C:/Windows/system32/ntdll.dll", I end up with the sysroot+in_pathname concatenated this way: (top-gdb) p temp_pathname $1 = 0x228b690 "/some/pathC:/Windows/system32/ntdll.dll" ^^ That is, a directory separator is missing. This is a regression. The problem is that solib_find decides that since the target path has a drive spec, a separator is not necessary, which is clearly wrong in this case. That check was added in <https://sourceware.org/ml/gdb-patches/2013-06/msg00028.html>, to handle the case of sysroot being "remote:". This patch fixes that original issue in a different way. Instead of checking whether the path has a drive spec, check whether the sysroot is "remote:". The patch adds a table that helps visualize the cases that need a separator. I also confirmed the original issue is still handled as expected. That is, that "set sysroot remote:" still does the right thing. remote_filename_p returns true if the filename is prefixed with "remote:". In this case, we need to check whether the filename is exactly "remote:". I thought of different ways or either changing remote_filename_p or adding another convenience function to remote.c to avoid exposing the "remote:" prefix out of remote.c. But all attempts turned out adding lot of over needless complication. So the patch just exposes the prefix behind a new macro, which allows using a straighforward strcmp. gdb/ 2013-09-27 Pedro Alves <palves@redhat.com> * remote.h (REMOTE_SYSROOT_PREFIX): New define. (remote_filename_p): Add comment. * remote.c (remote_filename_p): Adjust to use REMOTE_SYSROOT_PREFIX. * solib.c (solib_find): When deciding whether we need to add a directory separator, check whether the sysroot is "remote:" instead of checking whether the patch has a drive spec. Add comments.
2013-09-27remote.c: Remove unnecessary fields from 'struct stop_reply'.Pedro Alves2-20/+18
I noticed these fields aren't really necessary -- if the T stop reply indicated any we have any special event, the fallthrough doesn't really do anything. Tested on x86_64 Fedora 17 w/ local gdbserver, and also confirmed "catch load" against a Windows gdbserver running under Wine, which exercises TARGET_WAITKIND_LOADED, still works as expected. gdb/ 2013-09-27 Pedro Alves <palves@redhat.com> * remote.c (struct stop_reply) <solibs_changed, replay_event>: Delete fields. (remote_parse_stop_reply): Adjust, setting event->ws.kind directly.

2013-09-24Reimplement function calls on amd64-windowsJoel Brobecker2-32/+248
This patch provides a standalone implementation of function calls on amd64-windows, instead of providing some bits and pieces hooking into the function call implementation meant for sysV (in amd64-tdep). It makes better sense to do it this way, because the two ABIs are actually very different; for instance, the concept of argument classification, which is so central in the sysV ABI and drove the the implementation in amd64-tdep, makes no sense for Windows. It is therefore better for the Windows implementation to be completely separate, rather than rely on adaptations of the sysV implementation. gdb/ChangeLog: * amd64-tdep.c: #include "value.h" (amd64_windows_classify): Delete.
