2018-04-26x86: tighten assertion in build_modrm_byte()Jan Beulich2-4/+8
All VEX3SOURCES cases should have VexW set, and all should have a SIMD register destination.
2018-04-26x86: drop dead code from build_modrm_byte()Jan Beulich2-19/+10
There are no templates with VexImmExt and ImmExt set at the same time. There are also no VEX3SOURCES templates with CpuFMA. I assume both are left-overs from the implementation of an early specification which was later revised.

Define and handle TLS relocations for FDPIC in BFD and gas. In gas, the new relocations are rejected if the --fdpic option was not specified. We also define the __tdata_start symbol to mark the start of the .tdata section.

2018-04-25Fix new inferior events outputPedro Alves7-6/+26
Since f67c0c917150 ("Enable 'set print inferior-events' and improve detach/fork/kill/exit messages"), when detaching a remote process, we get, for detach against a remote target: (gdb) detach Detaching from program: ...., process 5388 Ending remote debugging. [Inferior 1 (Thread 5388.5388) detached] ^^^^^^^^^^^^^^^^ That is incorrect, for it is printing a thread id as string while we should be printing the process id instead. I.e., either one of: [Inferior 1 (process 5388) detached] [Inferior 1 (Remote target) detached] depending on remote stub support for the multi-process extensions. Similarly, after killing a process, we're printing thread ids while we should be printing process ids. E.g., on native GNU/Linux: (gdb) k Kill the program being debugged? (y or n) y [Inferior 1 (Thread 0x7ffff7faa8c0 (LWP 30721)) has been killed] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ while it should have been: Kill the program being debugged? (y or n) y [Inferior 1 (process 30721) has been killed] ^^^^^^^^^^^^^ There's a wording inconsistency between detach and kill: [Inferior 1 (process 30721) has been killed] [Inferior 1 (process 30721) detached] Given we were already saying "detached" instead of "has been detached", and we used to say just "exited", and given that the "has been" doesn't really add any information, this commit changes the message to just "killed": [Inferior 1 (process 30721) killed] gdb/ChangeLog: 2018-04-25 Pedro Alves <palves@redhat.com> * infcmd.c (kill_command): Print the pid as string, not the whole thread's ptid.

2018-04-24Enable 'set print inferior-events' and improve detach/fork/kill/exit messagesSergio Durigan Junior20-62/+266
This patch aims to turn 'set print inferior-events' always on, and do some cleanup on the messages printed by GDB when various inferior events happen (attach, detach, fork, kill, exit). To make sure that the patch is correct, I've tested it with a handful of combinations of 'set follow-fork-mode', 'set detach-on-fork' and 'set print inferior-events'. In the end, I decided to make my hand-made test into an official testcase. More on that below. Using the following program as an example: #include <unistd.h> int main () { fork (); return 0; } We see the following outputs from the patched GDB: - With 'set print inferior-events on': (gdb) r Starting program: a.out [Detaching after fork from child process 27749] [Inferior 1 (process 27745) exited normally] (gdb) - With 'set print inferior-events off': (gdb) r Starting program: a.out [Inferior 1 (process 27823) exited normally] (gdb) Comparing this against an unpatched GDB: - With 'set print inferior-events off' and 'set follow-fork-mode child': (gdb) r Starting program: a.out [Inferior 2 (process 5993) exited normally] (gdb) Compare this against an unpatched GDB: (unpatched-gdb) r Starting program: a.out [New process 5702] [Inferior 2 (process 5702) exited normally] (unpatched-gdb) It is possible to notice that, in this scenario, the patched GDB will lose the '[New process %d]' message. - With 'set print inferior-events on', 'set follow-fork-mode child' and 'set detach-on-fork on': (gdb) r Starting program: a.out [Attaching after process 27905 fork to child process 27909] [New inferior 2 (process 27909)] [Detaching after fork from parent process 27905] [Inferior 1 (process 27905) detached] [Inferior 2 (process 27909) exited normally] (gdb) Compare this output with an unpatched GDB, using the same settings: (unpatched-gdb) r Starting program: a.out [New inferior 28033] [Inferior 28029 detached] [New process 28033] [Inferior 2 (process 28033) exited normally] [Inferior 28033 exited] (unpatched-gdb) As can be seen above, I've also made a few modifications to messages that are printed when 'set print inferior-events' is on. For example, a few of the messages did not contain the '[' and ']' as prefix/suffix, which led to a few inconsistencies like: Attaching after process 22995 fork to child process 22999. [New inferior 22999] Detaching after fork from child process 22999. [Inferior 22995 detached] [Inferior 2 (process 22999) exited normally] So I took the opportunity and included the square brackets where applicable. I have also made the existing messages more uniform, by always printing "Inferior %d (process %d)..." where applicable. This makes it easier to identify the inferior number and the PID number from the messages. As suggested by Pedro, the "[Inferior %d exited]" message from 'exit_inferior' has been removed, because it got duplicated when 'inferior-events' is on. I'm also using the 'add_{thread,inferior}_silent' versions (instead of their verbose counterparts) on some locations, also to avoid duplicated messages. For example, a patched GDB with 'set print inferior-events on', 'set detach-on-fork on' and 'set follow-fork-mode child', but using 'add_thread', would print: (gdb) run Starting program: a.out [Attaching after process 25088 fork to child process 25092.] [New inferior 25092] <--- duplicated [Detaching after fork from child process 25092.] [Inferior 25088 detached] [New process 25092] <--- duplicated [Inferior 2 (process 25092) exited normally] But if we use 'add_thread_silent' (with the same configuration as before): (gdb) run Starting program: a.out [Attaching after process 31606 fork to child process 31610] [New inferior 2 (process 31610)] [Detaching after fork from parent process 31606] [Inferior 1 (process 31606) detached] [Inferior 2 (process 31610) exited normally] As for the tests, the configuration options being exercised are: - follow-fork-mode: child/parent - detach-on-fork: on/off - print inferior-events: on/off It was also necessary to perform adjustments on several testcases, because the expected messages changed considerably.

The stop due to a shared library event shows backtrace frame #0 function as r_debug_state() gdb/ChangeLog: PR gdb/23095 * gdb/testsuite/gdb.base/break-probes.exp: Pass shlib_load to prepare_for_testing. Set normal_bp to r_debug_state if target is bsd.

2018-04-21FreeBSD: Fix 'Couldn't get registers: Device busy' error (PR gdb/23077)Pedro Alves3-2/+15
As Rajendra SY reported at <https://sourceware.org/ml/gdb-patches/2018-04/msg00399.html>, several attach-related tests are failing on FreeBSD. The "attach" command errors with "Couldn't get registers: Device busy". When the "attach" command is executed, it calls target_attach -> inf_ptrace_attach, which just does the ptrace(PT_ATTACH), it does not wait for the child to stop with SIGSTOP. Afterwards, the command is complete and we go back to the event loop. The event loop wakes up and we end up in target_wait -> fbsd_wait, and handle the SIGSTOP stop. At the end of execute_command, though, before going back to the event loop, we check if the frame language changed via check_frame_language_change(). That reads the current PC, which is what leads to the registers read that fails. The problem is that we fail to mark the attached-to thread as executing between the initial attach, and the subsequent target_wait. Until we see the thread stop with SIGSTOP, we shouldn't try to read registers off of it. I guess there may a timing issue here - if you're "lucky", the thread may stop before gdb reads its registers, masking the problem. With that fixed, check_frame_language_change() becomes a nop until the thread is marked not-executing again, after target_wait is called and we go through handle_inferior_event -> normal_stop. We haven't seen the problem on Linux because there, the target_attach implementation waits for the thread to stop before returning. Still, that's supposedly hidden from the core, since the Linux target, like most targets, is a '!to_attach_no_wait' target.

2018-04-21Test that gcc -B picks up new ldAlan Modra2-0/+23
gcc configured using --with-ld always uses that particular version of ld if it exists. This patch adds a check that the ld version reported directly from ld-new matches that reported via gcc. I chose to compare the ld --version output rather than a more strict test (for example by gcc --print-prog-name=ld), because the version test allows a user to run the ld testsuite after installing a new ld (in the place expected by gcc). Sample output: Running target unix Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target. Using /usr/share/dejagnu/config/unix.exp as generic interface file for target. Using /home/alan/src/binutils-gdb/ld/testsuite/config/default.exp as tool-and-target-specific interface file.

2018-04-20PR22978, TLS local-dynamic incorrectly linked on hppa-linuxAlan Modra2-32/+48
We were emitting dynamic relocs on the second word of a TLS GD GOT entry pair (the dtprel offset), without the addend necessary when no symbol is present on the dynamic reloc. Unfortunately the simple solution of providing the proper addend doesn't work due to an hppa glibc ld.so bug that ignores such addends. So instead optimize the relocs. The dtprel offset is known at link time for locally defined symbols (the only case where we'll end up with no symbol on a dynamic reloc) so we can omit the dynamic reloc in that case. Furthermore, we can omit a dynamic reloc on the first word of a TLS GD GOT entry pair (the module id) if the symbol is local and we are producing an executable. Similarly, a tprel reloc on a TLS IE GOT entry is not needed for local symbols in an executable. So the condition for TLS GOT relocs can become bfd_link_dll(info) rather than bfd_link_pic(info) as needed for normal GOT relocs. This all presumes hppa ld.so doesn't need to differentiate TLS GD GOT pairs from TLS LD GOT pairs, which is currently true. PR 22978 * elf32-hppa.c (got_relocs_needed): Add extra param to special case both dtprel and tprel relocs. (allocate_dynrelocs): Adjust conditions for got relocs. (elf32_hppa_relocate_section): Likewise for local sym got relocs. Emit dynamic relocs on TLS GOT entries for shared libraries, not when pic. Omit dynamic reloc on dtprel entry when local, and on tprel entry when local and executable.

2018-04-19Add test case for a known hang in infrunRichard Bunt3-0/+188
The hang occurs when GDB tries to call inferior functions on two different threads with scheduler-locking turned on. The first call works fine, with the call to infrun_async(1) causing the signal_handler to be marked and the event to be handled, but then the event loop resets the "ready" member to zero, while leaving infrun_is_async set to 1. As a result, GDB hangs if the user switches to another thread and calls a second function because calling infrun_async(1) a second time has no effect, meaning the inferior call events are never handled. The added test case provokes the above issue. gdb/testsuite/ChangeLog: * gdb.threads/multiple-successive-infcall.c: New test. * gdb.threads/multiple-successive-infcall.exp: New file.
