Nick Clifton	2d054e6bfd	Fix stripping relocs in a file with mergeable notes. A recent Fedora bug (1520805) exposed a problem with objcopy's reloc copying code, when a binary also contains mergeable notes. The note merging code would delete some relocs, but then the reloc copying code would try to put them back again, which did not work. So I am checking in the patch below to fix the problem. The patch also tweaks one of the binutils note merging tests so that it is skipped for the Sparc64 target, since this has funky relocs. binutils * objcopy.c (copy_relocations_in_section): Use the orelocations field of the input section, if it has been initialised. * testsuite/binutils-all/note-2-64.d: Skip test on Sparc64. bfd * elfcode.h (elf_write_relocs): Check for an empty howto field.	8 years ago

Keith Seitz	fa6eb693cf	Validate explicit locations with early termination breakpoints/22569 involves an internal error generated by the rather innocent looking command: (gdb) break -source test.cpp main .../linespec.c:3302: internal-error: void decode_line_full(...): Assertion `result.size () == 1 \|\| canonical->pre_expanded' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) The input string is tokenized into "-source", "test.cpp", and "main" (input parsing breaks on whitespace). create_breakpoint is then called with the explicit location (containing only the source file name) and "main" as the extra_string argument. No SaLs are created for this underspecified explicit location, and the "result.size () == 1" evaluates false (as does the pre_expanded condition). This triggers the assertion. Normally string_to_explicit_location validates the input string. However, the presence of the string "main" causes the parser to exit early: 802 else 803 { 804 /* End of the explicit location specification. 805 Stop parsing and return whatever explicit location was 806 parsed. / 807 argp = start; 808 return location; 809 } This bypasses the validation that is done a few lines down in this function which would have emitted the expected error. This patch fixes that. Additionally, this patch also fixes an inconsistency with error reporting in this use case: (gdb) b -source foo Source filename requires function, label, or line offset. (gdb) b -source foo main No source file named foo. These two commands should have elicited the same error message. gdb/ChangeLog: PR breakpoints/22569 * location.c (string_to_explicit_location): When terminating parsing early, break out of enclosing loop instead of returning. gdb/testsuite/ChangeLog: PR breakpoints/22569 * gdb.linespec/ls-errs.exp: Change expected result of "break -source this file has spaces.c -line 3".

Keith Seitz	883fd55ab1	Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue. Upshot: the test suite now has stack and queue data structures that may be used by test writers. gdb/ChangeLog * NEWS (New commands): Mention set/show print type nested-type-limit. * c-typeprint.c (c_type_print_base): Print out nested types. * dwarf2read.c (struct typedef_field_list): Rename to ...

Tom Tromey	99598d713f	Fix regression in "commands" Pedro pointed out a regression in "commands", where trying to clear a breakpoint's command list would fail: (top-gdb) commands Type commands for breakpoint(s) 3, one per line. End with a line saying just "end". >end No breakpoints specified. (top-gdb) I believe the bug was introduced by my patch that changes counted_command_line to be a shared_ptr. This causes the problem because now the counted_command_line in commands_command_1 can be NULL, whereas previously it never could be. After some discussion, we agreed to simply remove the error case from commands_command_1. 2017-12-07 Tom Tromey <tom@tromey.com> PR breakpoints/22511: * breakpoint.c (commands_command_1): Don't throw an exception when no commands have been read. 2017-12-07 Tom Tromey <tom@tromey.com> * gdb.base/break.exp: Add test for empty "commands".	9 years ago

Yao Qi	a880623024	Initialize target description early in IPA Target descriptions are allocated lazily, that is fine in GDBserver, but it is not safe to call malloc in gdb_collect in IPA, because we can set a fast tracepoint in malloc, and when the tracepoint is hit, gdb_collect/malloc is called, deadlock or memory corruption may be triggered. #0 0xf7cfc200 in malloc () #1 0xf7efdc07 in operator new(unsigned int) () #2 0xf7ef7636 in allocate_target_description() () #3 0xf7efcbe1 in i386_create_target_description(unsigned long long, bool) () #4 0xf7efb474 in i386_linux_read_description(unsigned long long) () #5 0xf7efb190 in get_ipa_tdesc(int) () #6 0xf7ef9baa in gdb_collect () The fix is to initialize all target descriptions earlier, when the IPA is loaded.

Simon Marchi	9a93831ccc	Fix syscall group completion The test gdb.base/catch-syscall.exp has been failing since commit `3d415c26ba` Remove cleanups from break-catch-syscall.c The reason is that we are putting into the group_ptr array a pointer to the buffer of the local string object. If the string is small enough to fit in the internal string buffer (used for small string optimizations), the pointer will point to the local object directly. So even if we std::move the string to the vector, the pointer in group_ptr will still point to the local object. When we reuse that object (technically a new instance, but most likely the same memory) for the next syscall, we'll overwrite the previous string. The result is that we'll get less results than expected, since there will be duplicates. We'll also run into problems if we push the string to the vector, and then record the c_str () pointer using the string object in the vector. The vector might get reallocated, the string may move in memory, and our pointer in group_ptr will point to stale memory. Instead, we have to push all the strings first, then, when we know the vector won't change anymore, build the group_ptr array. This is what this patch does. gdb/ChangeLog: * break-catch-syscall.c (catch_syscall_completer): Get pointers to syscall group strings after building the string vector.	8 years ago

Alan Modra	3bf083ed23	dyn_relocs tidy Many targets define their own dyn_relocs struct when they could use struct elf_dyn_relocs. This patch tidies that, and uses readonly_dynrelocs in a few more places. The SH adjust_dynamic_symbol had some really weird code dating back to 2002 that looked over dynamic relocations for any in SEC_HAS_CONTENTS or SEC_READONLY sections, rather than just the usual SEC_READONLY sections. So basically any dynamic relocation. What's more, the SH relocate_section has no support for emitting dynamic relocations in non-PIC. In other words, SH has no support for avoiding copy relocs in non-PIC. I've made that more obvious by using "if (0 && ..)" in asjust_dynamic_symbol. Unfortunately, LM32, M32R, NDS32, and OR1K copied the bogus SH adjust_dynamic_symbol code. So none of those targets would have avoided copy relocs. LM32, M32R, NDS32 get the "if (0)" treatment too. (LM32 is even more broken in that non_got_ref is never set.) OR1K relocate_section looks like it might support dynamic relocs in non-PIC, so I've enabled the copy reloc avoidance code for that target. * elf32-hppa.c (struct elf32_hppa_dyn_reloc_entry): Delete.

Simon Marchi	858c9d1324	Address review comments for the previous series I failed at git and missed adding/lost changes on the wrong branch, the result being that I didn't incorporate fixes resulting from Yao's review comments.

There are two places where we should use the unique pointer typedef, and ChangeLog entries missing. gdb/ChangeLog: * target-descriptions.c (struct tdesc_feature) <registers>: Use tdesc_reg_up typedef. (struct target_desc) <features>: Use tdesc_feature_up typedef.	8 years ago
Simon Marchi	d4a0e8b57d	Split tdesc_type into multiple classes This patch makes tdesc_type an abstract base class and creates three subclasses: - tdesc_type_builtin, for builtin types - tdesc_type_vector, for vector types - tdesc_type_with_fields, for struct, union, flag and enum types This allows getting rid of the union in tdesc_type and to not allow the std::vector separately. I tried to go further and create separate classes for struct, union, flag and enum, but it proved too difficult. One problem is that from the point of the of the target description code, the types tdesc_type_* are opaque (only forward-declared). Therefore, it doesn't know about inheritance relationship between those classes. This makes it impossible to make functions that accept a pointer to a base class and pass a pointer to a derived class, for example. I think this patch here is a good compromise, and if somebody wants to improve things further, the door is open. A make_gdb_type virtual pure method is added to tdesc_type, which replaces the current tdesc_gdb_type function. Calling this method on a tdesc_type returns the corresponding built gdb type. gdb/ChangeLog: * target-descriptions.c (struct tdesc_type): Use default destructor. <u>: Remove. <accept>: Remove.

I have not removed everything reported by -Wunused, because some expressions such as struct type arg_type = check_typedef (value_type); in bfin-tdep.c could have an unexpected but important side-effect. I removed others that I considered more low-risk, such as: struct gdbarch gdbarch = get_objfile_arch (objfile); I tested building with Python 2/Python 3/no Python, with/without expat, with/without libipt and with/without babeltrace. gdb/ChangeLog: * ada-lang.c (ada_collect_symbol_completion_matches): Remove unused variables.

Sergio Lopez	afa840dcc0	Implement 'set dump-excluded-mappings' command Commit `df8411da08` implemented support for checking /proc/PID/coredump_filter, and also changed gcore behavior to unconditionally honor the VM_DONTDUMP flag, preventing sections marked as such for being dumped into the core file. This patch implements the 'set dump-excluded-mappings' command for instructing gdb to ignore the VM_DONTDUMP flag. Combined with 'set use-coredump-filter', this allows the user to restore the old behavior, dumping all sections (except the ones marked as IO) unconditionally. gdb/Changelog: 2017-11-29 Sergio Lopez <slp@redhat.com> * linux-tdep.c (dump_excluded_mappings): New variable. (dump_mapping_p): Use dump_excluded_mappings variable. (_initialize_linux_tdep): New command 'set dump_excluded_mappings'.	8 years ago
