2016-10-18Update gnulib to current upstream masterPedro Alves174-766/+2178
I tried building gdb with G++ 4.7 and CXX="g++ -std=gnu+11", and that tripped on a build error: In file included from build-gnulib/import/stdio.h:53:0, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/common/common-defs.h:31, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/defs.h:28, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/armobsd-tdep.c:20: build-gnulib/import/stddef.h:104:3: error: conflicting declaration ‘typedef union max_align_t max_align_t’ In file included from build-gnulib/import/stddef.h:55:0, from build-gnulib/import/stdio.h:53, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/common/common-defs.h:31, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/defs.h:28, from /home/pedro/gdb/mygit/cxx-convertion/src/gdb/armobsd-tdep.c:20: /opt/gcc-4.7/lib/gcc/x86_64-unknown-linux-gnu/4.7.4/include/stddef.h:426:3: error: ‘max_align_t’ has a previous declaration as ‘typedef struct max_align_t max_align_t’ Updating gnulib to current master fixes it, since it brings in this fix: http://lists.gnu.org/archive/html/bug-gnulib/2016-04/msg00000.html Our last update was in August 2015. This doesn't bring in much added baggage, it's mostly bug fixes. It pulled in the "limits-h" module as automatic dependency, and given that looks potentially useful I added it to the set of modules we require. Tested on x86_64 Fedora 23, with g++ 4.7 and g++ 5.3, native and gdbserver. gdb/ChangeLog: 2016-10-18 Pedro Alves <palves@redhat.com> * gnulib/update-gnulib.sh (GNULIB_COMMIT_SHA1): Set to

2016-10-18Introduce gdb::unique_ptrPedro Alves3-0/+394
Many make_cleanup uses in the code base are best eliminated by using a "owning" smart pointer to manage ownership of the resource automatically. The question is _which_ smart pointer. GDB currently supports building with a C++03 compiler. We have std::auto_ptr in C++03, but, as is collective wisdom by now, that's too easy to misuse, and has therefore been deprecated in C++11 and finally removed in C++17. It'd be nice to be able to use std::unique_ptr instead, which is the modern, safe std::auto_ptr replacement in C++11. In addition to extra safety -- moving (i.e., transfer of ownership of the managed pointer between smart pointers) must be explicit -- std::unique_ptr has (among others) one nice feature that std::auto_ptr doesn't --- ability to specify a custom deleter as template parameter. In gdb's context, that allows easily creating a smart pointer for memory allocated with xmalloc -- the smart pointer then knows to release with xfree instead of delete. This is particularly interesting when managing objects allocated in C libraries, and also, for C++-fying parts of GDB that interact with other parts that still return objects allocated with xmalloc. Since std::unique_ptr's API is quite nice, and eventually we'd like to move to C++11, this patch adds a C++03-compatible smart pointer that exposes the subset of the std::unique_ptr API that we're interested in. An advantage is that whenever we start requiring C++11, we won't have to learn a new API. Meanwhile, this allows continuing to support building with a C++03 compiler. Since C++03 doesn't support rvalue references (boost gets close to emulating them, but it's not fully transparent to user code), the C++03 std::unique_ptr emulation here doesn't try hard to prevent accidentally moving, which is where most of complication of a more thorough emulation would be. Instead, we rely on the fact that GDB will be usually compiled with a C++11 compiler, and use the real std::unique_ptr in that case to catch such accidental moves. IOW, the goal here is to allow code that would be correct using std::unique_ptr to be equally correct in C++03 mode, and, just as efficient. The C++03 version was originally based on GCC 7.0's std::auto_ptr and then heavily customized to behave more like C++11's std::unique_ptr: - Support for custom (stateless) deleters. (Support for stateful deleters could be added, if necessary.) - unique_ptr<T[]> partial specialization (auto_ptr<T> does not know to use delete[]). - Support for all of 'ptr != NULL', 'ptr == NULL' and 'if (ptr)' using the safe bool idiom to emulate C++11's explicit bool operator. - There's no nullptr in C++03, so this allows initialization and assignment from NULL instead (std::auto_ptr allows neither). - Variable names un-uglified (ie., no leading __ prefix everywhere). - Formatting made to follow GDB's coding conventions, including comment style. - Converting "move" constructors done differently in order to truly support: unique_ptr<Derived> func_returning_unique_ptr (.....); ... unique_ptr<Base> ptr = func_returning_unique_ptr (.....); At this point, it no longer shares much at all with the original file, but, that's the history. See comments in the code to find out more. I thought of putting the "emulation" / shim in the "std" namespace, so that when we start requiring C++11 at some point, no actual changes to users of the smart pointer throughout would be necessary. Putting things in the std namespace is technically undefined, however in practice it doesn't cause any issue with any compiler. However, thinking that people might be confused with seeing std::unique_ptr and thinking that we're actually requiring C++11 already, I put the new types in the "gdb" namespace instead. For managing xmalloc pointers, this adds a gdb::unique_xmalloc_ptr<T> "specialization" with a custom xfree deleter. No actual use of any smart pointer is introduced in this patch. That'll be done in following patches. Tested (along with the rest of the series) on: - NetBSD 5.1 (gcc70 on the compile farm), w/ gcc 4.1.3 - x86-64 Fedora 23, gcc 5.3.1 (gnu++03) - x86-64 Fedora 23, and gcc 7.0 (gnu++14) gdb/ChangeLog: 2016-10-18 Pedro Alves <palves@redhat.com> * common/common-defs.h: Include "gdb_unique_ptr.h". * common/gdb_unique_ptr.h: New.

2016-10-14[ARC] Disassembler: fix LIMM detection for short instructions.Claudiu Zissulescu9-2/+60
The ARC (short) instructions are using a special register number to indicate is the instruction uses a long immediate (LIMM). In the case of short instruction, this LIMM indicator depends on the ISA version used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same value used in "long" instructions. However, for the ARCv2 processors, this LIMM indicator is 0x1E. This patch fixes the LIMM detection for ARCv1 ISA and adds two tests. gas/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/gas/arc/shortlimm_a7.d: New file. * testsuite/gas/arc/shortlimm_a7.s: Likewise. * testsuite/gas/arc/shortlimm_hs.d: Likewise. * testsuite/gas/arc/shortlimm_hs.s: Likewise. include/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * opcode/arc.h (ARC_OPCODE_ARCV2): New define. opcodes/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * arc-dis.c (find_format_from_table): Discriminate LIMM indicator usage on ISA basis.

2016-10-13Convert tid_range_parser and get_number_or_range to classesPedro Alves13-359/+401
This converts tid_range_parser and get_number_or_range to be classes. The various tid_range_parser_* and get_number_or_range_* functions become methods on the respective classes. Then it updates the users to follow. The rationale for the change is that this provides better encapsulation. For example, this forced me to think of a better interface between tid_range_parser and get_number_or_range, since the former peeked into the latter's internals a bit too much. That ended up resulting mostly in these two not-just-straight-1-1 changes: void -tid_range_parser_skip (struct tid_range_parser *parser) +tid_range_parser::skip_range () { ... - tid_range_parser_init (parser, parser->range_parser.end_ptr, - parser->default_inferior); + m_range_parser.skip_range (); + init (m_range_parser.string (), m_default_inferior); } and: /* If we successfully parsed a thread number or finished parsing a thread range, switch back to assuming the next TID is inferior-qualified. */ - if (parser->range_parser.end_ptr == NULL - || parser->range_parser.string == parser->range_parser.end_ptr) + if (!m_range_parser.in_range ()) { For the same reason (encapsulation), this moves the enum tid_range_state definition to within the tid_parser class's scope, since that is private implementation detail.

2016-10-12Fixup gdb.python/py-value.exp for bare-metal aarch64-elfLuis Machado3-5/+21
I noticed that testing aarch64-elf gdb with a physical board ran into issues with gdb.python/py-value.exp. Further investigation showed that we were actually trying to dereference a NULL pointer (argv) when trying to access argv[0]. Being bare-metal, argv is not guaranteed to be valid. So we need to make sure argv is sane before accessing argv[0]. The following patch fixes up the test program to check for a NULL argv and also improves the testcase a bit so it doesn't have to work with a hardcoded argc value. Regression-tested on x86-64 Ubuntu 16.04. gdb/testsuite/ChangeLog: 2016-10-12 Luis Machado <lgustavo@codesourcery.com> * gdb.python/py-value.c (main): Check if argv is NULL before using it. * gdb.python/py-value.exp (test_value_in_inferior): Don't use hardcoded argc values.
