2017-04-12Fix PR c++/21323: GDB thinks char16_t and char32_t are signed in C++Pedro Alves7-6/+214
While the C++ standard says that char16_t and char32_t are unsigned types: Types char16_t and char32_t denote distinct types with the same size, signedness, and alignment as uint_least16_t and uint_least32_t, respectively, in <cstdint>, called the underlying types. ... gdb treats them as signed currently: (gdb) p (char16_t)-1 $1 = -1 u'\xffff' There are actually two places in gdb that hardcode these types: - gdbtypes.c:gdbtypes_post_init, when creating the built-in types, seemingly used by the "x /s" command (judging from commit 9a22f0d0). - dwarf2read.c, when reading base types with DW_ATE_UTF encoding (which is what is used for these types, when compiling for C++11 and up). Despite the comment, the type created does end up used. Both places need fixing. But since I couldn't tell why dwarf2read.c needs to create a new type, I've made it use the per-arch built-in types instead, so that the types are only created once per arch instead of once per objfile. That seems to work fine. While writting the test, I noticed that the C++ language parser isn't actually aware of these built-in types, so if you try to use them without a program that uses them, you get: (gdb) set language c++ (gdb) ptype char16_t No symbol table is loaded. Use the "file" command. (gdb) ptype u"hello" No type named char16_t. (gdb) p u"hello" No type named char16_t. That's fixed by simply adding a couple entries to C++'s built-in types array in c-lang.c. With that, we get the expected: (gdb) ptype char16_t type = char16_t (gdb) ptype u"hello" type = char16_t [6] (gdb) p u"hello" $1 = u"hello" gdb/ChangeLog: 2017-04-12 Pedro Alves <palves@redhat.com> PR c++/21323 * c-lang.c (cplus_primitive_types) <cplus_primitive_type_char16_t, cplus_primitive_type_char32_t>: New enum values.

2017-04-12C++-fy and prepare for sharing fork_inferiorSergio Durigan Junior20-176/+220
As a preparation for the next patch, which will move fork_inferior from GDB to common/ (and therefore share it with gdbserver), it is interesting to convert a few functions to C++. This patch touches functions related to parsing command-line arguments to the inferior (see gdb/fork-child.c:breakup_args), the way the arguments are stored on fork_inferior (using std::vector instead of char **), and the code responsible for dealing with argv also on gdbserver. I've taken this opportunity and decided to constify a few arguments to fork_inferior/create_inferior as well, in order to make the code cleaner. And now, on gdbserver, we're using xstrdup everywhere and aren't checking for memory allocation failures anymore, as requested by Pedro: <https://sourceware.org/ml/gdb-patches/2017-03/msg00191.html> Message-Id: <025ebdb9-90d9-d54a-c055-57ed2406b812@redhat.com> Pedro Alves wrote: > On the "== NULL" check: IIUC, the old NULL check was there to > handle strdup returning NULL due to out-of-memory. > See NULL checks and comments further above in this function. > Now that you're using a std::vector, that doesn't work or make > sense any longer, since if push_back fails to allocate space for > its internal buffer (with operator new), our operator new replacement > (common/new-op.c) calls malloc_failure, which aborts gdbserver. > > Not sure it makes sense to handle out-of-memory specially in > the gdb/rsp-facing functions nowadays (maybe git blame/log/patch > submission for that code shows some guidelines).

IMO this refactoring was very good to increase the readability of the code as well, because some parts of the argument handling were unnecessarily confusing before. gdb/ChangeLog: 2017-04-12 Sergio Durigan Junior <sergiodj@redhat.com> * common/common-utils.c (free_vector_argv): New function. * common/common-utils.h: Include <vector>.

2017-04-11Fix read after xfree in linux-nat.c:linux_nat_detachPhilipp Rudo2-1/+4
At the end of linux_nat_detach the main_lwp is deleted (delete_lwp). This is problematic as during detach (detach_one_lwp and linux_fork_detach) main_lwp already gets freed.

When trying to build for x86_64-w64-mingw32: /home/simark/src/binutils-gdb/gdb/windows-nat.c: In function ‘void windows_detach(target_ops*, const char*, int)’: /home/simark/src/binutils-gdb/gdb/windows-nat.c:1915:20: error: converting to ‘ptid_t’ from initializer list would use explicit constructor ‘constexpr ptid_t::ptid_t(int, long int, long int)’ ptid_t ptid = {-1}; ^ Fixed by initializing ptid with the minus_one_ptid variable. gdb/ChangeLog: * windows-nat.c (windows_detach): Initialize ptid with minus_one_ptid.

2017-04-06Class-ify ptid_tSimon Marchi7-77/+350
I grew a bit tired of using ptid_get_{lwp,pid,tid} and friends, so I decided to make it a bit easier to use by making it a proper class. The fields are now private, so it's not possible to change a ptid_t field by mistake. The new methods of ptid_t map to existing functions/practice like this: ptid_t (pid, lwp, tid) -> ptid_build (pid, lwp, tid) ptid_t (pid) -> pid_to_ptid (pid) ptid.is_pid () -> ptid_is_pid (ptid) ptid == other -> ptid_equal (ptid, other) ptid != other -> !ptid_equal (ptid, other) ptid.pid () -> ptid_get_pid (ptid) ptid.lwp_p () -> ptid_lwp_p (ptid) ptid.lwp () -> ptid_get_lwp (ptid) ptid.tid_p () -> ptid_tid_p (ptid) ptid.tid () -> ptid_get_tid (ptid) ptid.matches (filter) -> ptid_match (ptid, filter) I've replaced the implementation of the existing functions with calls to the new methods. People are encouraged to gradually switch to using the ptid_t methods instead of the functions (or we can change them all in one pass eventually). Also, I'm not sure if it's worth it (because of ptid_t's relatively small size), but I have made the functions and methods take ptid_t arguments by const reference instead of by value. gdb/ChangeLog: * common/ptid.h (struct ptid): Change to... (class ptid_t): ... this. <ptid_t>: New constructors. <pid, lwp_p, lwp, tid_p, tid, is_pid, operator==, operator!=, matches>: New methods. <make_null, make_minus_one>: New static methods. <pid>: Rename to... <m_pid>: ...this. <lwp>: Rename to... <m_lwp>: ...this. <tid>: Rename to... <m_tid>: ...this. (ptid_build, ptid_get_pid, ptid_get_lwp, ptid_get_tid, ptid_equal, ptid_is_pid, ptid_lwp_p, ptid_tid_p, ptid_match): Take ptid arguments as references, move comment to class ptid_t. * common/ptid.c (null_ptid, minus_one_ptid): Initialize with ptid_t static methods. (ptid_build, pid_to_ptid, ptid_get_pid, ptid_get_tid, ptid_equal, ptid_is_pid, ptid_lwp_p, ptid_tid_p, ptid_match): Take ptid arguments as references, implement using ptid_t methods. * unittests/ptid-selftests.c: New file. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/ptid-selftests.c.
