2017-04-05-Wwrite-strings: Constify word break character arraysPedro Alves8-34/+69
-Wwrite-strings flags several cases of missing casts around initializations like: static char *gdb_completer_command_word_break_characters = " \t\n!@#$%^&*()+=|~`}{[]\"';:?/>.<,"; Obviously these could/should be const. However, while at it, there's no need for these variables to be pointers instead of arrays. They are never changed to point to anything else. Unfortunately, readline's rl_completer_word_break_characters is "char *", not "const char *". So we always need a cast somewhere. The approach taken here is to add a new set_rl_completer_word_break_characters function that becomes the only place that writes to rl_completer_word_break_characters, and thus the single place that needs the cast. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_completer_word_break_characters): Now a const array. (ada_get_gdb_completer_word_break_characters): Constify. * completer.c (gdb_completer_command_word_break_characters) (gdb_completer_file_name_break_characters) (gdb_completer_quote_characters): Now const arrays.

-Wwrite-strings flagged a missing cast for example here: static char * ravenscar_extra_thread_info (struct target_ops *self, struct thread_info *tp) { return "Ravenscar task"; Since callers are not supposed to free the string returned by these methods, change the methods' signature to return const strings. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * aix-thread.c (aix_thread_pid_to_str) (aix_thread_extra_thread_info): Constify. * bsd-kvm.c (bsd_kvm_pid_to_str): Constify. * bsd-uthread.c (bsd_uthread_extra_thread_info) (bsd_uthread_pid_to_str): Constify. * corelow.c (core_pid_to_str): Constify. * darwin-nat.c (darwin_pid_to_str): Constify. * fbsd-nat.c (fbsd_pid_to_str): Constify. * fbsd-tdep.c (fbsd_core_pid_to_str, gdbarch_core_pid_to_str): Constify. * gnu-nat.c (gnu_pid_to_str): Constify. * go32-nat.c (go32_pid_to_str): Constify. * i386-cygwin-tdep.c (i386_windows_core_pid_to_str): Constify. * inf-ptrace.c (inf_ptrace_pid_to_str): Constify. * inferior.c (inferior_pid_to_str): Constify. * linux-nat.c (linux_nat_pid_to_str): Constify. * linux-tdep.c (linux_core_pid_to_str): Constify. * linux-thread-db.c (thread_db_pid_to_str) (thread_db_extra_thread_info): Constify. * nto-tdep.c (nto_extra_thread_info): Constify. * nto-tdep.h (nto_extra_thread_info): Constify. * obsd-nat.c (obsd_pid_to_str): Constify. * procfs.c (procfs_pid_to_str): Constify. * ravenscar-thread.c (ravenscar_extra_thread_info) (ravenscar_pid_to_str): Constify. * remote-sim.c (gdbsim_pid_to_str): Constify. * remote.c (remote_threads_extra_info, remote_pid_to_str): Constify. * sol-thread.c (solaris_pid_to_str): Constify. * sol2-tdep.c (sol2_core_pid_to_str): Constify. * sol2-tdep.h (sol2_core_pid_to_str): Constify. * target.c (default_pid_to_str, target_pid_to_str) (normal_pid_to_str, default_pid_to_str): Constify. * target.h (target_ops::to_pid_to_str) (target_ops::to_extra_thread_info): Constify.

2017-04-05-Wwrite-strings: Don't initialize string command variables to empty stringPedro Alves3-3/+8
-Wwrite-strings flags these initializations as requiring a cast. However, these variables are command variables, and as such point to heap-allocated memory. The initial allocation is always done when the corresponding command is registered. E.g.,: dprintf_function = xstrdup ("printf"); add_setshow_string_cmd ("dprintf-function", class_support, &dprintf_function, _("\ Set the function to use for dynamic printf"), _("\ Show the function to use for dynamic printf"), NULL, update_dprintf_commands, NULL, &setlist, &showlist); That's why we never reach a bogus attempt to free these string literals. So, just drop the incorrect initializations. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * breakpoint.c (dprintf_function, dprintf_channel): Don't initialize. * tracepoint.c (default_collect): Don't initialize.
2017-04-05-Wwrite-strings: Constify macroexp.c:init_shared_bufferPedro Alves2-11/+23
There's one call in the file that passes a string literal, like: init_shared_buffer (&va_arg_name, "__VA_ARGS__", strlen ("__VA_ARGS__")); Instead of adding a cast here, make init_shared_buffer take a 'const char *', and remove the several casts in the file that are made obsolete. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * macroexp.c (macro_buffer::shared): Now a bool. (init_buffer): Update. (init_shared_buffer): Constify 'addr' parameter. (substitute_args, expand, macro_expand, macro_expand_next): Remove casts.
2017-04-05-Wwrite-strings: Constify struct disassemble_info's disassembler_options fieldPedro Alves11-15/+32
The memory disassemble_info::disassembler_options points to is always owned by the client. I.e., that field is an non-owning, observing pointer. Thus const makes sense. Are the include/ and opcodes/ bits OK? Tested on x86_64 Fedora 23, built with --enable-targets=all. include/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * dis-asm.h (disassemble_info) <disassembler_options>: Now a "const char *".

See: http://www.boost.org/doc/libs/1_63_0/libs/optional/doc/html/boost_optional/tutorial/gotchas/false_positive_with__wmaybe_uninitialized.html I noticed that replacing the gdb::optional uses with real C++17 std::optional uses against GCC 7/trunk makes the warnings go away. Looking at the implementation, AFAICS, libstdc++ always initializes its "empty" union payload member (_M_empty, which is defined as an empty class, like ours). I.e., all payload types have this ctor: struct _Optional_payload..... { constexpr _Optional_payload() : _M_empty() {} The constexpr makes a diference too. Without it, GCC7 still warns. So I'm applying the same treatment to our gdb::optional. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * common/gdb_optional.h (optional::optional): Make constexpr and initialize m_dummy.

2017-04-04PR ld/21233: Avoid sweeping forced-undefined symbols in section GCMaciej W. Rozycki9-0/+101
Complement commit 902e9fc76a0e ("PR ld/20828: Move symbol version processing ahead of GC symbol sweep"), commit b531344c34b0 ("PR ld/20828: Reorder the symbol sweep stage of section GC") and commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced local with section GC"), and prevent symbols forcibly entered in the output file with the use of the `--undefined=' or `--require-defined=' linker command line options or the EXTERN linker script command from being swept in section garbage collection and consequently recorded in the dynamic symbol table as local entries. This happens in certain circumstances, where a symbol reference also exists in one of the static input files, however only in a section which is garbage-collected and does not make it to the output file, and the symbol is defined in a dynamic object present in the link. For example with the `i386-linux' target and the `pr21233.s' and `pr21233-l.s' sources, and the `pr21233.ld' linker script included with this change we get: $ as -o pr21233-l.o pr21233-l.s $ ld -shared -T pr21233.ld -o libpr21233.so pr21233-l.o $ as -o pr21233.o pr21233.s $ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so $ readelf --dyn-syms pr21233 Symbol table '.dynsym' contains 2 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 OBJECT LOCAL DEFAULT UND bar $ which makes the run-time `bar' dependency of the `pr21233' executable different from its corresponding link-time dependency, i.e. the presence of `libpr21233.so' and its `bar' symbol is required at the link time, however at the run time a copy of `libpr21233.so' without `bar' will do. Similarly with `--undefined=' and EXTERN which do not actually require the reference to the symbol requested to be satisfied with a definition at the link time, however once the definition has been pulled at the link time, so it should at the dynamic load time. Additionally with the `mips-linux' target we get: $ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so ld: BFD (GNU Binutils) 2.28.51.20170324 assertion fail .../bfd/elfxx-mips.c:3861 $ as the target is not prepared to handle such a local dynamic symbol. With this change in effect we get: $ readelf --dyn-syms pr21233 Symbol table '.dynsym' contains 2 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 0 OBJECT GLOBAL DEFAULT UND bar $ instead, for both targets. ld/ PR ld/21233 * ldlang.c (insert_undefined): Set `mark' for ELF symbols. * testsuite/ld-elf/pr21233.sd: New test. * testsuite/ld-elf/pr21233-l.sd: New test. * testsuite/ld-elf/pr21233.ld: New test linker script. * testsuite/ld-elf/pr21233-e.ld: New test linker script. * testsuite/ld-elf/pr21233.s: New test source. * testsuite/ld-elf/pr21233-l.s: New test source. * testsuite/ld-elf/shared.exp: Run the new tests.

However, this library has not been used as the default library since FreeBSD 5.0 (2003) and 4.11 (2005).

2017-04-04dwarf2read.c: C++fy lnp_state_machinePedro Alves2-198/+267
While I was looking at the file, I noticed that this struct could be nicely converted to a class. As I was progressing, I ended up moving all state machine actual internal state manipulation to methods of lnp_state_machine, essentially decoupling DWARF parsing from state tracking. I also noticed that the lnp_reader_state doesn't really serve any good use, so that's eliminated in the process. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * dwarf2read.c (lnp_state_machine): Now a class.

2017-04-04Make sect_offset and cu_offset strong typedefs instead of structsPedro Alves12-384/+900
A while ago, back when GDB was a C program, the sect_offset and cu_offset types were made structs in order to prevent incorrect mixing of those offsets. Now that we require C++11, we can make them integers again, while keeping the safety, by exploiting "enum class". We can add a bit more safety, even, by defining operators that the types _should_ support, helping making the suspicious uses stand out more. Getting at the underlying type is done with the new to_underlying function added by the previous patch, which also helps better spot where do we need to step out of the safety net. Mostly, that's around parsing the DWARF, and when we print the offset for complaint/debug purposes. But there are other occasional uses. Since we have to define the sect_offset/cu_offset types in a header anyway, I went ahead and generalized/library-fied the idea of "offset" types, making it trivial to add more such types if we find a use. See common/offset-type.h and the DEFINE_OFFSET_TYPE macro. I needed a couple generaly-useful preprocessor bits (e.g., yet another CONCAT implementation), so I started a new common/preprocessor.h file. I included units tests covering the "offset" types API. These are mostly compile-time tests, using SFINAE to check that expressions that shouldn't compile (e.g., comparing unrelated offset types) really are invalid and would fail to compile. This same idea appeared in my pending enum-flags revamp from a few months ago (though this version is a bit further modernized compared to what I had posted), and I plan on reusing the "check valid expression" bits added here in that series, so I went ahead and defined the CHECK_VALID_EXPR macro in its own header -- common/valid-expr.h. I think that's nicer regardless. I was borderline between calling the new types "offset" types, or "index" types, BTW. I stuck with "offset" simply because that's what we're already calling them, mostly. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/offset-type-selftests.c.

2017-04-04dwarf2read.c: Make dir_index and file_name_index strong typedefsPedro Alves3-74/+149
This should help catch mistakes related to mixing the 1-based DWARF indexes with 0-based std::vector indexes, since the new types do not implicitly convert to anything. The change in read_formatted_entries relates to the fact that doing the seemingly simpler: - uintp = &fe.dir_index; + uintp = (unsigned int *) &fe.dir_index; would be undefined C/C++. So to address that, I made the function extract the form before assigning to the file_entry. It felt natural to use gdb::optional for "do I have this value", and this is what motivated the previous patch that added the missing observer methods to gdb::optional. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * common/underlying.h: New file. * dwarf2read.c: Include "common/gdb_optional.h" and "common/underlying.h". (dir_index, file_name_index): New types. (file_entry): Use them. (file_entry::include): Use to_underlying. (line_header::add_file_name): Use dir_index. (read_formatted_entries): Use gdb::optional. Read form before writting to file_entry. (dwarf_decode_line_header): Use dir_index. (lnp_state_machine::current_file): Use to_underlying. (lnp_state_machine::file): Change type to file_name_index.

Currently, gdb::optional is really minimal and can only be used for lazy initialization. There's no way to get at the value contained inside the optinal.

This will be used in the following patch. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * common/gdb_optional.h (gdb::optiona): Add operator->, operator*, operator bool, has_value and get methods.
2017-04-04dwarf2read.c: Some C++fycation, use std::vector, std::unique_ptrPedro Alves2-180/+166
This starts off as replacing a couple custom open coded vector implementations in the file with std::vector, and then the rest falls off of that. I.e., use new/delete instead of XCNEW/xfree, add ctors/dtors/initializers where appropriate. And then use std::unique_ptr instead of cleanups. Some functions became methods, and in a couple spots, some single-use callback functions that would have to be tweaked anyway are converted to lambdas instead. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * dwarf2read.c (struct file_entry): Add ctors, and initialize all fields.

2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu40-31/+660
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary. The assembler syntax: .section .mbind.foo,"adx",%progbits ^ 0: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.foo,"adx",%progbits,0x1 ^ 1: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2 ^ 2: Special memory type. | 'd' for SHF_GNU_MBIND. bfd/ * elf.c (get_program_header_size): Add a GNU_MBIND segment for each GNU_MBIND section and align GNU_MBIND section to page size.

Stop. This patch makes the clean target clear the .deps directory, which gives the user a chance to recover from the error wihtout knowing about the internals of the build system.

2017-03-31gdbserver: Suffix generated C files with -generatedSimon Marchi3-65/+33
I noticed that there were some missing files in gdbserver's gitignore (some generated register format .c files). Of course the easy fix would be to add those files to .gitignore, but I think we can do a better job, so that we don't have to worry about adding generated files to .gitignore or the clean Makefile target. I suggest naming all generated source files -generated.c. This way, we can use a single rule in .gitignore and do a "rm -f *-generated.c" to clean them up.
