* Use scoped_restore for ui_fileTom Tromey2016-10-215-48/+23
| | | | | | | | | | | | | | This replaces all the uses of make_cleanup_restore_ui_file with scoped_restore. 2016-10-21 Tom Tromey <tom@tromey.com> * utils.c (make_cleanup_restore_ui_file, do_restore_ui_file) (struct restore_ui_file_closure): Remove. * utils.h (make_cleanup_restore_ui_file): Don't declare. * guile/scm-ports.c (ioscm_with_output_to_port_worker): Use scoped_restore. * top.c (execute_command_to_string): Use scoped_restore.
* Use RAII to save and restore scalarsTom Tromey2016-10-2113-77/+155
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces many (but not all) uses of make_cleanup_restore_integer with a simple RAII-based template class. It also removes the similar restore_execution_direction cleanup in favor of this new class. Subsequent patches will replace other similar cleanups with this class. The class is typically instantiated using make_scoped_restore. This allows for template argument deduction. 2016-10-21 Tom Tromey <tom@tromey.com> * common/scoped_restore.h: New file. * utils.h: Include scoped_restore.h. * top.c (execute_command_to_string): Use scoped_restore. * python/python.c (python_interactive_command): Use scoped_restore.

* Fix symbol table file name on AIXUlrich Weigand2016-10-212-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When xlc -qfuncsect or gcc -ffunction-sections options is used in AIX, each function csect is associated with each psymtab, so each psymtab will have it's corresponding filename entries set. If the pst filename isn't set then we will be seeing the below output when we set a breakpoint. (gdb) br main Breakpoint 1 at 0x10000374: file _start_ , line 18. With the fix it will be. (gdb) br main Breakpoint 1 at 0x10000518: file test.c, line 24.

* gdb: no longer define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROSPedro Alves2016-10-182-16/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | My gnulib fix at: https://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00010.html was merged upstream meanwhile and our gnulib copy now includes it. As a concidence, Kevin was telling me today that these macros are causing a build problem on FreeBSD: common/common-defs.h:47:0: error: "__STDC_CONSTANT_MACROS" redefined [-Werror] #define __STDC_CONSTANT_MACROS 1 /usr/include/sys/cdefs.h:408:0: note: this is the location of the previous definition #define __STDC_CONSTANT_MACROS (and a similar error for __STDC_LIMIT_MACROS) The problem seems to be that we should be defining these input macros before including any system header, but, we're not. So let's just revert e063da67902e ([C++] Define __STDC_CONSTANT_MACROS / __STDC_LIMIT_MACROS for stdint.h). If this causes a problem somewhere, we can re-define the macros higher up in the file, before system headers are included. gdb/ChangeLog: 2016-10-18 Pedro Alves <palves@redhat.com> * common/common-defs.h (__STDC_CONSTANT_MACROS) (__STDC_LIMIT_MACROS): Delete.

* Introduce gdb::unique_ptrPedro Alves2016-10-183-0/+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.
