2015-08-27Fix ChangeLog entries starting with "Likewise"Simon Marchi2-2/+4
The first lines of these ChangeLog entries are "Likewise"... it doesn't make much sense.
2015-08-27[Cell/B.E.] Fix wrong relocation for TLS variable offsetUlrich Weigand2-1/+6
When debugging Cell/B.E. code, the cross-architecture frame unwinding works by accessing data structures refered to by a thread-local variable in the inferior. While accessing this variable via minimal symbol, code would use BMSYMBOL_VALUE_ADDRESS to determine the offset of the variable in the thread-local storage block. This is incorrect, since it adds any relocation offset of the shared library defining the TLS variable. That offset would be OK when accessing the initial copy present in the .tbss section, but it must not be applied to the offset of the variable in the TLS block at runtime. Depending on whether or not the libspe2.so library was prelinked, access to the variable would fail due to the incorrectly relocated offset. ChangeLog: * ppc-linux-tdep.c (ppc_linux_spe_context_lookup): Do not attempt to relocate a TLS variable offset.
2015-08-27[Cell/B.E.] Make parse_spufs_run more robustUlrich Weigand2-1/+16
With recent changes to inferior handling, parse_spufs_run needs to be more careful in assumptions it makes. In particular, this patch: - Bails out early if the current inferior has not yet been registered (e.g. during fork procession) to avoid assertion failures in register cache code. - Sets inferior_ptid to the current ptid while calling target_read_memory to make sure the correct process is accessed if parse_spufs_run is called early when inferior_ptid has not yet been switched by the caller. ChangeLog: * spu-multiarch.c (parse_spufs_run): Bail out if inferior is not registered yet. Set inferior_ptid while calling target_read_memory.
2015-08-27Detect SW breakpoints in Cell/B.E. combined debuggingUlrich Weigand5-6/+25
The Linux target and gdbserver now check the siginfo si_code reported on a SIGTRAP to detect whether the trap indicates a software breakpoint was hit. Unfortunately, on Cell/B.E., the kernel uses an si_code value of TRAP_BRKPT when a SW breakpoint was hit in PowerPC code, but a si_code value of SI_KERNEL when a SW breakpoint was hit in SPU code. This patch updates Linux target and gdbserver to accept both si_code values to indicate SW breakpoint on PowerPC. ChangeLog: * nat/linux-ptrace.h (GDB_ARCH_TRAP_BRKPT): Replace by ... (GDB_ARCH_IS_TRAP_BRKPT): ... this. Add __powerpc__ case. * linux-nat.c (check_stopped_by_breakpoint): Use GDB_ARCH_IS_TRAP_BRKPT instead of GDB_ARCH_TRAP_BRKPT. gdbserver/ChangeLog: * linux-low.c (check_stopped_by_breakpoint): Use GDB_ARCH_IS_TRAP_BRKPT instead of GDB_ARCH_TRAP_BRKPT.
2015-08-27Fix assertion failure in linux-thread-dbUlrich Weigand2-4/+13
Since we are no longer using thread events by default in linux-thread-db, the find_new_threads_once routine contains an assertion that it should never be called on a live inferior unless using thread events: gdb_assert (!target_has_execution || thread_db_use_events ()); However, there is a code path from thread_db_get_thread_local_address that will in fact call find_new_threads_once in some scenarios. In particular, this is currently always triggered when starting up any Cell/B.E. combined exeuctable. To fix this, this patch removes the call to thread_db_find_new_threads_1 when the current thread was not yet detected. In its place, we now just call thread_from_lwp to detect this one thread if necessary. ChangeLog: * linux-thread-db.c (thread_db_get_thread_local_address): If the thread was not yet discovered, use thread_from_lwp instead of calling thread_db_find_new_threads_1.
2015-08-27Report UNRESOLVED on failures while detecting Cell/B.E.Ulrich Weigand2-1/+6
The gdb.cell testcases use the predicate skip_cell_tests defined in lib/cell.exp to determine whether Cell/B.E. test cases ought to be run. This tests verifies that we have a toolchain that supports generating combined Cell/B.E. binaries, and that the target machine actually is a Cell/B.E. In order to do so, a small test program is built and run (under the debugger). Any failure is taken as a sign that we don't have a Cell/B.E. machine and the tests are to be skipped. This has the unfortunate effect that a serious bug in GDB that causes internal compiler errors even on the trivial test program does not lead to any failures in the testsuite, since now all gdb.cell test are simply skipped. This patch changes skip_cell_tests to at least report UNRESOLVED in cases where execution of the test program fails in unexpected ways. testsuite/ChangeLog: * lib/cell.exp (skip_cell_tests): Report UNRESOLVED on unexpected failures to run the test program under GDB.

2015-08-27More fallout from "Allow symbol and label names to be enclosed in double quotes"Alan Modra18-92/+134
Some of the TC_START_LABEL implementations need to adjust the end of the symbol, when a colon doesn't mean a label definition. That means they need access to nul_char both the restore the NUL location (it may be a quote rather than a colon) and to store the new nul_char. Others need adjusting to step over a potential trailing quote. PR gas/18581 * config/tc-aarch64.h (TC_START_LABEL): Redefine. * config/tc-arm.c (tc_start_label_without_colon): Delete params.

2015-08-27Fix inverted statements in m88k_analyze_prologueSimon Marchi2-2/+7

2015-08-27Document non-8-bits addressable memory support in NEWSSimon Marchi2-0/+11
I think it would be a good idea to document that gdb now has (basic) support to read/write memory on architectures with non-8-bits memory. Hopefully somebody will see it and say "Hey! We can now (more easily) port GDB to our strange DSP that has 32-bits-addressable memory!" and do it. gdb/ChangeLog: * NEWS: Document support for non-8-bits addressable memory.

2015-08-27gdb: Drop use of obsolete AC_TYPE_SIGNALPedro Alves4-37/+5
Since we're using sighandler_t, nothing else refers to RETSIGTYPE in gdb. (Actually, given gdb/remote.c has been assuming signal handlers return void for a long time, we could have gotten get rid of this even without gnulib's sighandler_t.) gdb/ChangeLog: 2015-08-27 Pedro Alves <palves@redhat.com> * configure.ac: Remove AC_TYPE_SIGNAL call. * configure, config.in: Regenerate.

2015-08-27Mention language in compile error messageLuis Machado2-1/+7
This patch improves one of the compile error messages by mentioning the language. Before - No compiler support for this language. After - No compiler support for language <language>. gdb/ChangeLog: 2015-08-26 Luis Machado <lgustavo@codesourcery.com> * compile/compile.c (compile_to_object): Mention language in error message.
2015-08-27Force language to C in gdb.compile/compile-ifunc.expLuis Machado2-0/+11
Due to the lack of debug information in the binary, GDB is unable to figure out what language is being used. This may be a problem when doing remote debugging and the binary stops at the entry point containing asm code. In this case GDB will switch to asm as current language and will not switch back to C when it reaches main, which in turn causes the compile feature check to malfunction. This is solved by forcing the language to C after reaching main. gdb/testsuite/ChangeLog: 2015-08-26 Luis Machado <lgustavo@codesourcery.com> * gdb.compile/compile-ifunc.exp (with_test_prefix): Force language to C.

2015-08-26Replace some xmalloc-family functions with XNEW-family onesSimon Marchi177-675/+906
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

2015-08-26Fix native follow-exec-mode "new"Don Breazeal3-3/+21
This patch fixes a segmentation fault in native GDB when handling an exec event with follow-exec-mode set to "new".

So on entry to exit_inferior_num_silent we had two inferiors with the same ptid. In the calls made by exit_inferior_num_silent, the current inferior is temporarily saved and replaced in order to make use of functions that only operate on the current inferior (for example, in do_all_continuations, called while deleting the threads of the original inferior). When we restored the original inferior, we just took the first inferior that matched the ptid of the original and got the new (wrong) one. It hadn't been initialized yet and had no gdbarch pointer, and GDB segfaulted. The fix for that is to call exit_inferior_num_silent before adding the new inferior, so that we never have two inferiors with the same ptid. Then exit_inferior_num_silent uses the original inferior as the current inferior throughout, and can find a valid gdbarch pointer. Once we have finished with the exit of the old inferior and added the new one, we need to create a new thread for the new inferior. In the function that called follow_exec, handle_inferior_event_1, ecs->event_thread now points to the thread that was deleted with the exit of the original inferior. To remedy this we create the new thread, and once we return from follow_exec we reset ecs->event_thread. Note that we are guaranteed that we can reset ecs->event_thread safely using inferior_thread because we have set the current inferior in follow_exec, and inferior_ptid was set by the call to context_switch at the beginning of exec event handling. gdb/ChangeLog: * infrun.c (follow_exec): Re-order operations for handling follow-exec-mode "new". (handle_inferior_event_1): Assign ecs->event_thread to the current thread. * remote.c (get_remote_arch_state): Add an assertion.
2015-08-26New test for follow-exec-modeDon Breazeal3-0/+242
This patch implements a new GDB test for follow-exec-mode. Although there is a GDB test for debugging across an exec, there is no test for follow-exec-mode. This test is derived from gdb.base/foll-exec.exp, and re-uses execd-prog.c as the program to exec. The following behavior is tested: follow-exec-mode == "same" - 'next' over the exec, check for one inferior - 'continue' past the exec to a breakpoint, check for one inferior - after the exec, use a 'run' command to run the current binary follow-exec-mode == "new" - 'next' over the exec, check for two inferiors - 'continue' past the exec to a breakpoint, check for two inferiors - after the exec, use a 'run' command to run the current binary - after the exec, use the 'inferior' command to switch inferiors, then use a 'run' command to run the current binary Note that single-step breakpoints do not survive across an exec. There has to be a breakpoint in the execed program in order for it to stop right after the exec. gdb/testsuite/ChangeLog: * gdb.base/foll-exec-2.c: New test program. * gdb.base/foll-exec-2.exp: New test.

When a shared library is listed twice on the command line, the linker ignores the second mention.

2015-08-25remote: allow aborting long operations (e.g., file transfers)Pedro Alves9-21/+143
Currently, when remote debugging, if you type Ctrl-C just while the target stopped for an internal event, and GDB is busy doing something that takes a while (e.g., fetching chunks of a shared library off of the target, with vFile, to process ELF headers and debug info), the Ctrl-C is lost. The patch hooks up the QUIT macro to a new target method that lets the target react to the double-Ctrl-C before the event loop is reached, which allows reacting to a double-Ctrl-C even when GDB is busy doing some long operation and not waiting for a stop reply. That end result is: (gdb) c Continuing. ^C ^C Interrupted while waiting for the program. Give up waiting? (y or n) y Quit (gdb) info threads Id Target Id Frame * 1 Thread 11673 0x00007ffff7deb240 in _dl_debug_state () from target:/lib64/ld-linux-x86-64.so.2 (gdb) If, however, GDB is waiting for a stop reply (because the target has been resumed, with e.g., vCont;c), but the target isn't responding, we now get: (gdb) c Continuing. ^C ^C The target is not responding to interrupt requests. Stop debugging it? (y or n) y Disconnected from target. (gdb) info threads No threads. This offers to disconnect, because when we're waiting for a stop reply, there's nothing else we can send the target other than an interrupt request. And if that doesn't work, there's nothing else we can do. The Ctrl-C is presently lost because until we get to a user-visible stop, the SIGINT handler that is installed is the one that forwards the interrupt to the remote side, with the \003 "packet" [1]. But, gdbserver ignores an interrupt request if the program is stopped. Still, even if it didn't, the server can only report back a stop-because-of-SIGINT when the program is next resumed. And it may take a while to actually re-resume the target. [1] - In the old sync days, the remote target would react to a double-Ctrl-C by asking users whether they wanted to give up waiting and disconnect. The code is still there, but it it isn't reacheable on most hosts, which support serial connections in async mode (probably only DJGPP doesn't). Even then, in sync mode, remote.c's SIGINT handler is only installed while the target is resumed, and is removed as soon as the target sends back a stop reply. That means that a Ctrl-C just while GDB is processing an internal event can end up with an odd "Quit" at the prompt instead of "Program stopped by SIGINT". In contrast, in async mode, remote.c's SIGINT handler is set up as long as target_terminal_inferior or target_terminal_ours_for_output are in effect (IOW, until we get a user-visible stop and call target_terminal_ours), so the user shouldn't get back a spurious Quit. However, it's still desirable to be able to interrupt a long-running GDB operation, if GDB takes a while to re-resume the target or get back to the event loop.

2015-08-25DWARF: handle non-local references in nested functionsPierre-Marie de Rodat45-155/+1003
GDB's current behavior when dealing with non-local references in the context of nested fuctions is approximative: - code using valops.c:value_of_variable read the first available stack frame that holds the corresponding variable (whereas there can be multiple candidates for this); - code directly relying on read_var_value will instead read non-local variables in frames where they are not even defined. This change adds the necessary context to symbol reads (to get the block they belong to) and to blocks (the static link property, if any) so that GDB can make the proper decisions when dealing with non-local varibale references. gdb/ChangeLog: * ada-lang.c (ada_read_var_value): Add a var_block argument and pass it to default_read_var_value. * block.c (block_static_link): New accessor. * block.h (block_static_link): Declare it. * buildsym.c (finish_block_internal): Add a static_link argument.
