The header file demangle.h has changed in release 2.32 making it incompatible with the ones shipping with gcc and gdb. For inclusion in the unified source this conflict causes build failure in binutils. Renaming demangle.h to demangle2.h allows for both revisions to coexist and building from unified source to succeed.

…b/23379) This commit fixes a 8.1->8.2 regression exposed by gdb.python/py-evthreads.exp when testing with --target_board=native-gdbserver. gdb.log shows: src/gdb/thread.c:93: internal-error: thread_info* inferior_thread(): Assertion `tp' failed.

The problem is that when we get to frame adapteva#3/adapteva#4, we lost all references to the thread that is being marked as running. create_continue_event_object assumes that it is the current thread, which is not true in this case. Fix this by passing down the right thread in create_continue_event_object. Also remove create_thread_event_object's default argument and have the only other caller left pass down the right thread explicitly too. gdb/ChangeLog: 2018-08-24 Pedro Alves <palves@redhat.com> Simon Marchi <simon.marchi@ericsson.com> PR gdb/23379 * python/py-continueevent.c: Include "gdbthread.h".

The solib_create_inferior_hook call in symbol_file_command was added by
commit ea142fb ("Fix breakpoints on file reloads for PIE
binaries"). It causes solib_create_inferior_hook to be called while
the inferior is not running, which darwin_solib_create_inferior_hook
does not expect. darwin_solib_get_all_image_info_addr_at_init, in
particular, assumes that there is a current thread, as it tries to get
the current thread's regcache.
Fix it by adding a target_has_execution check and returning early. Note
that there is a similar check in svr4_solib_create_inferior_hook.
gdb/ChangeLog:
* solib-darwin.c (darwin_solib_create_inferior_hook): Return
early if no execution.

GDB had opened remote shared libraries via the target: sysroot, so it tries closing them. GDBserver is tearing down already, so remote communication breaks down and we close the remote target and throw TARGET_CLOSE_ERROR. Note frame #14: #14 0x0000555555ae4730 in objfile::~objfile (this=0x555556515540, __in_chrg=<optimized out>) at src/gdb/objfiles.c:573 That's a dtor, thus noexcept. That's the reason for the std::terminate. Stepping back a bit, why do we still have open remote files if we've managed to detach already, and, we're debugging with "target remote"? The reason is that commit 408f668 makes detach_command hold a reference to the target, so the remote target won't be finally closed until frame #28 returns. It's closing the target that invalidates target file I/O handles. This commit fixes the issue by not relying on target_close to invalidate the target file I/O handles, instead invalidate them immediately in remote_unpush_target. So when GDB purges the solibs, and we end up in target_fileio_close (frame adapteva#7 above), there's nothing to do, and we don't try to talk with the remote target anymore. The regression isn't seen when testing with --target_board=native-gdbserver, because that does "set sysroot" to disable the "target:" sysroot, for test run speed reasons. So this commit adds a testcase that explicitly tests detach with "set sysroot target:". gdb/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> PR gdb/28080 * remote.c (remote_unpush_target): Invalidate file I/O target handles. * target.c (fileio_handles_invalidate_target): Make extern. * target.h (fileio_handles_invalidate_target): Declare. gdb/testsuite/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> PR gdb/28080 * gdb.base/detach-sysroot-target.exp: New. * gdb.base/detach-sysroot-target.c: New.

That's the reason for the std::terminate. The previous patch fixed things such that the exception above isn't thrown anymore. However, it's possible that e.g., the remote connection drops just while a user types "nosharedlibrary", or some other reason that leads to objfile::~objfile, and then we end up the same std::terminate problem. Also notice that frames adapteva#9-adapteva#11 are BFD frames: adapteva#9 0x0000555555e09e3f in opncls_bclose (abfd=0x555556bc27e0) at src/bfd/opncls.c:599 adapteva#10 0x0000555555e0a2c7 in bfd_close_all_done (abfd=0x555556bc27e0) at src/bfd/opncls.c:847 adapteva#11 0x0000555555e0a27a in bfd_close (abfd=0x555556bc27e0) at src/bfd/opncls.c:814 BFD is written in C and thus throwing exceptions over such frames may either not clean up properly, or, may abort if bfd is not compiled with -fasynchronous-unwind-tables (x86-64 defaults that on, but not all GCC ports do). Thus frame adapteva#8 seems like a good place to swallow exceptions. More so since in this spot we already ignore target_fileio_close return errors. That's what this commit does. Without the previous fix, we'd see: (gdb) detach Detaching from program: target:/any/program, process 2197701 Ending remote debugging. [Inferior 1 (process 2197701) detached] warning: cannot close "target:/lib64/ld-linux-x86-64.so.2": Remote connection closed Note it prints a warning, which would still be a regression compared to GDB 10, if it weren't for the previous fix. gdb/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> PR gdb/28080 * gdb_bfd.c (gdb_bfd_close_warning): New.

This is only one cog in the adapteva/epiphany-sdk building toolchain wheel. Consider this PR a final attempt to get attention from Adapteva maintainers. If this doesn't get merged post haste it is pointless submitting PRs for the additional fixes to epiphany-sdk and dependents. We will need to start looking at another location to continue development at. Because the epiphany-sdk scripts are depended on several Adapteva projects at location, if these projects have indeed been abandoned even manual patching is futile as building the epiphany toolchain will not be possible.
This PR:
The header file
demangle.hhas changed in release 2.32 making it incompatible with the ones shipping with gcc and gdb.For inclusion in the unified source this conflict causes build failure in binutils. Renaming
demangle.htodemangle2.hallows for both revisions to coexist and building from unified source to succeed.
