2015-04-23Delay setting up compressed debug section namesH.J. Lu6-63/+175
When we set up st_name for output section name in elf_fake_sections, we don't know if the compressed DWARF debug section will be smaller. We may end up with compressed DWARF debug sections which are bigger than the uncompressed ones. This patch delays setting up st_name for output DWARF debug section to _bfd_elf_assign_file_positions_for_non_load which will compress the output debug section. We also postpone placement of shstrtab section after DWARF debug sections have been compressed.

2015-04-23Fix gdb.base/interrupt.exp racy fail against gdbserverPedro Alves2-2/+17
Currently, against gdbserver, interrupt.exp occasionaly fails like this: ERROR: Process no longer exists UNRESOLVED: gdb.base/interrupt.exp: send end of file The problem is that we see gdbserver exiting before we match gdb's output: expect: does "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" (spawn_id exp8) match regular expression "end of file"? Gate "end of file"? gate=no expect: read eof expect: set expect_out(spawn_id) "exp8" expect: set expect_out(buffer) "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" Fix this by removing $inferior_spawn_id from the set of spawn ids expect is watching as soon as we see the "end of file" string out of the inferior spawn id, using an indirect spawn id list.

2015-04-23gdb_test_multiple match eof of any spawn_idPedro Alves2-0/+9
Since silent handling of eof is usually the wrong thing to do, this patch makes gdb_test_multiple handle it for all $any_spawn_id. Currently, against gdbserver, interrupt.exp occasionaly fails like this: FAIL: gdb.base/interrupt.exp: send end of file gdb.log with expect debug output enabled shows: expect: does "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" (spawn_id exp8) match regular expression "end of file"? Gate "end of file"? gate=no expect: read eof expect: set expect_out(spawn_id) "exp8" expect: set expect_out(buffer) "\r\n\r\nChild exited with status 0\r\nGDBserver exiting\r\n" FAIL: gdb.base/interrupt.exp: send end of file Note "expect: read eof" for spawn_id=exp8. exp8 is inferior_spawn_id/gdbserver_spawn_id. That means expect/gdb_test_multiple saw gdbserver exit before we got the expected gdb output. Since there's no explicit pattern for "eof", expect (and thus gdb_test_multiple) just returns. After this commit, we get instead: ERROR: Process no longer exists UNRESOLVED: gdb.base/interrupt.exp: send end of file Note that before we still got an FAIL because $saw_inferior_exit is 0 when we get to: gdb_assert { $saw_eof && $saw_inferior_exit } $msg Fixing the fail (now unresolved) will be the subject of a separate patch. gdb/testsuite/ChangeLog: 2015-04-23 Pedro Alves <palves@redhat.com> * lib/gdb.exp (gdb_test_multiple): Match eof/full_buffer/timeout on $any_spawn_id instead of only on $gdb_spawn_id.

2015-04-23Explicitly call rl_resize_terminal() in TUI's SIGWINCH handlerPatrick Palka2-0/+6
In readline 6.3, the semantics of SIGWINCH handling has changed. When a SIGWINCH signal is raised, readline's rl_sigwinch_handler() now does not immediately call rl_resize_terminal(). Instead it sets a flag that is checked by RL_CHECK_SIGNALS() at a point where readline has control, and calls rl_resize_terminal() if said flag is set. This change is item (c) in https://cnswww.cns.cwru.edu/php/chet/readline/CHANGES c. Fixed a bug that caused readline to try and run code to modify its idea of the screen size in a signal handler context upon receiving a SIGWINCH. This change in behavior is important to us because TUI's tui_sigwinch_handler() relies on the assumption that by the time it's called, readline will have updated its knowledge of the terminal dimensions via rl_resize_terminal(). Since this assumption no longer holds true, TUI's SIGWINCH handling does not work correctly with readline 6.3. To fix this issue this patch makes TUI explicitly call rl_resize_terminal() in tui_async_resize_screen() at the point where current terminal dimensions are needed. (We could call it in tui_sigwinch_handler too, but since readline avoids doing it, we are probably safer off avoiding to call it in signal handler context as well.) After this change, SIGWINCH handling continues to work properly with both readline 6.2 and 6.3. Since we no longer need it, we could now explicitly disable readline's SIGWINCH handler by setting rl_catch_sigwinch to zero early on in the program startup but I can't seem to find a good spot to place this assignment (the first call to rl_initialize() occurs in tui_initialize_readline() so the assignment should occur before then), and the handler is harmless anyway. gdb/ChangeLog: * tui/tui-win.c (tui_async_resize_screen): Call rl_resize_terminal().

2015-04-22windows-nat: Don't change current_event.dwThreadId in ↵Jon Turney2-2/+8
handle_output_debug_string() Using the 'catch-signal' test from the testsuite, on x86_64 Cygwin: $ ./gdb testsuite/outputs/gdb.base/catch-signal/catch-signal.exe [...] (gdb) catch signal Catchpoint 1 (standard signals) (gdb) r [...] Catchpoint 1 (signal SIGHUP), main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ (gdb) c Continuing. main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ Failed to resume program execution (ContinueDebugEvent failed, error 87) (gdb) This error occurs because when handle_output_debug_string processes a Cygwin signal message, it re-writes current_event.dwThreadId to reflect the thread that the signal will be delivered to, which can be different to the thread reporting the signal. Altering current_event.dwThreadId() will cause ContinueDebugEvent() to be applied to the wrong thread and fail. So, rather than re-writing the thread id in current_event, use the thread id by returning it. With this patch applied this test now yields the expected result: $ ./gdb testsuite/outputs/gdb.base/catch-signal/catch-signal.exe [...] (gdb) catch signal Catchpoint 1 (standard signals) (gdb) r [...] Catchpoint 1 (signal SIGHUP), main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ (gdb) c Continuing.

2015-04-22windows-nat: Report an error if ContinueDebugEvent() failsJon Turney2-0/+10
Using the 'catch-signal' test from the testsuite, on x86_64 Cygwin: $ ./gdb testsuite/outputs/gdb.base/catch-signal/catch-signal.exe [...] (gdb) catch signal Catchpoint 1 (standard signals) (gdb) r [...] Catchpoint 1 (signal SIGHUP), main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ (gdb) c Continuing. [hangs] This is due to a defect in the way Cygwin signals are handled: When handle_output_debug_string processes a Cygwin signal message, it re-writes current_event.dwThreadId to reflect the thread that the signal will be delivered to. Subsequently, the call to ContinueDebugEvent will fail, because we're trying to resume the wrong thread. GDB is then stuck waiting forever for another event that will never come. This patch doesn't fix the problem, it just adds appropriate error handling. Using error() seems appropriate here, if ContinueDebugEvent() fails, the inferior is in an unknown state and we will probably not be debugging it anymore. With this patch applied, resuming the execution of the program now yields: $ ./gdb testsuite/outputs/gdb.base/catch-signal/catch-signal.exe [...] (gdb) catch signal Catchpoint 1 (standard signals) (gdb) r [...] Catchpoint 1 (signal SIGHUP), main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ (gdb) c Continuing. main () at ../../../gdb/testsuite/gdb.base/catch-signal.c:40 40 raise (SIGHUP); /* second HUP */ Failed to resume program execution (ContinueDebugEvent failed, error 87) (gdb) gdb/ChangeLog: 2015-04-22 Jon Turney <jon.turney@dronecode.org.uk> * windows-nat.c (windows_continue): Report an error if ContinueDebugEvent() fails.

2015-04-22Rewrite relro adjusting codeAlan Modra6-42/+50
The linker tries to put the end of the last section in the relro segment exactly on a page boundary, because the relro segment itself must end on a page boundary. If for any reason this can't be done, padding is inserted. Since the end of the relro segment is typically between .got and .got.plt, padding effectively increases the size of the GOT. This isn't nice for targets and code models with limited GOT addressing. The problem with the current code is that it doesn't cope very well with aligned sections in the relro segment. When making .got aligned to a 256 byte boundary for PowerPC64, I found that often the initial alignment attempt failed and the fallback attempt to be less than adequate. This is a particular problem for PowerPC64 since the distance between .got and .plt affects the size of plt call stubs, leading to "stubs don't match calculated size" errors. So this rewrite takes a direct approach to calculating a new relro base. Starting from the last section in the segment, we calculate where it must start to position its end on the boundary, or as near as possible considering alignment requirements. The new start then becomes the goal for the previous section to end, and so on for all sections. This of course ignores the possibility that user scripts will place . = ALIGN(xxx); in the relro segment, or provide section address expressions. In those cases we might fail, but the old code probably did too, and a fallback is provided. ld/ * ldexp.h (struct ldexp_control): Delete dataseg.min_base.

2015-04-21Fix pascal behavior for class fields with testcasePierre Muller6-4/+157
Problem reported as PR pascal/17815 Part 1/3: Remember the case pattern that allowed finding a field of this. File gdb/p-exp.y modified This is the fix in the pascal parser (p-exp.y), to avoid the error that GDB does find normal variables case insensitively, but not fields of this, inside a class or object method. Part 2/3: Add "class" option for pascal compiler File gdb/testsuite/lib/pascal.exp This part of the patch series is unchanged. It adds class option to pascal compiler which adds the required command line option to accept pascal class types. Part 3/3: New file: gdb/testsuite/gdb.pascal/case-insensitive-symbols.exp New file: gdb/testsuite/gdb.pascal/case-insensitive-symbols.pas Here is an updated version of this test, using Pedro's suggestions. Test to check that PR 17815 is fixed.

This commit introduces a new shared function to replace identical functions in GDB and gdbserver.
2015-04-21sim: mcore: clean up printf warningsMike Frysinger2-8/+13
These printf statements are showing "word" objects which are typedefed from long, so make sure to use l with %x when printing them to avoid warnings from gcc.
2015-04-21sim: mcore: convert to common memory/verbose functionsMike Frysinger2-319/+59
Re-use the existing memory core that handles reads/writes. The verbose command is converted to the common --verbose flag since only a few call sites use it now.
2015-04-21sim: mcore: drop watchpoint/dumpmem/clearstats supportMike Frysinger2-73/+12
In preparation for converting to the common memory framework, the custom commands get in our way. But when we realize that gdb support has been dropped for mcore, it makes things a bit easier: the main runner does not let you run arbitrary commands once simulation starts. So lets disable watchpoint support until it can be converted to the common watchpoint logic. There's already an ifdef to let us do that. We straight up drop support for the dumpmem command (no other sim supports this, and if it's a feature people want, we can add a common func) and the clearstats command (not a big deal -- just restart your simulation). We leave in place the verbose check points as a follow up commit will cut that over to common logic.
2015-04-21sim: mcore: switch to common syscall handlingMike Frysinger6-140/+64
Now that libgloss has a header tracking the syscalls for this arch, we can update the database to include it for the symbolic constants/maps. Then we can switch the mcore syscall callbacks over to the common ones.
2015-04-21sim: gennltvals.sh: handle split out newlib source treeMike Frysinger5-17/+32
Since newlib no longer shares the same repo as binutils/gdb, we have to go searching further afield to locate the sources. We still look at the top level for newlib, but if that is not found, we also try up one dir outside of this source tree. It sucks, but better than the status quo (no workie).

commit 9ad5cbcfb23cb74d34bd04f88f4e47c0f5de5155 added the initial support for more than 64k ELF sections with holes for reserved section indices in section header table and set entries of reserved section indices in section header table to index 0: for (secn = 1; secn < section_number; ++secn) - i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd), - i_shdrp[secn]->sh_name); - + if (i_shdrp[secn] == NULL) + i_shdrp[secn] = i_shdrp[0]; + else + i_shdrp[secn]->sh_name = _bfd_elf_strtab_offset (elf_shstrtab (abfd), + i_shdrp[secn]->sh_name); commit 4fbb74a6055f7d48f09c44064073d3b1e99c6642 removed holes in section header table. Check for i_shdrp[secn] == NULL is no longer needed now. This patch removes it. * elf.c (assign_section_numbers): Always set up sh_name.
