gdb: select "Cygwin" OS ABI for Cygwin binaries Before this patch, the "Windows" OS ABI is selected for all Windows executables, including Cygwin ones. This patch makes GDB differentiate Cygwin binaries from non-Cygwin ones, and selects the "Cygwin" OS ABI for the Cygwin ones. To check whether a Windows PE executable is a Cygwin one, we check the library list in the .idata section, see if it contains "cygwin1.dll". I had to add code to parse the .idata section, because BFD doesn't seem to expose this information. BFD does parse this information, but only to print it in textual form (function pe_print_idata): https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=blob;f=bfd/peXXigen.c;h=e42d646552a0ca1e856e082256cd3d943b54ddf0;hb=HEAD#l1261 Here's the relevant portion of the PE format documentation: https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#the-idata-section This page was also useful: https://blog.kowalczyk.info/articles/pefileformat.html#9ccef823-67e7-4372-9172-045d7b1fb006 With this patch applied, this is what I get: (gdb) file some_mingw_x86_64_binary.exe Reading symbols from some_mingw_x86_64_binary.exe... (gdb) show osabi The current OS ABI is "auto" (currently "Windows"). The default OS ABI is "GNU/Linux". (gdb) file some_mingw_i386_binary.exe Reading symbols from some_mingw_i386_binary.exe... (gdb) show osabi The current OS ABI is "auto" (currently "Windows"). The default OS ABI is "GNU/Linux". (gdb) file some_cygwin_x86_64_binary.exe Reading symbols from some_cygwin_x86_64_binary.exe... (gdb) show osabi The current OS ABI is "auto" (currently "Cygwin"). The default OS ABI is "GNU/Linux". gdb/ChangeLog: * windows-tdep.h (is_linked_with_cygwin_dll): New declaration. * windows-tdep.c (CYGWIN_DLL_NAME): New. (pe_import_directory_entry): New struct type. (is_linked_with_cygwin_dll): New function. * amd64-windows-tdep.c (amd64_windows_osabi_sniffer): Select GDB_OSABI_CYGWIN if the BFD is linked with the Cygwin DLL. * i386-windows-tdep.c (i386_windows_osabi_sniffer): Likewise.

/* Windows signal numbers differ between MinGW flavors and between
gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment. (cygwin_init_abi): New declaration. * windows-tdep.c: Split signal enumeration in two, one for Windows and one for Cygwin. (windows_gdb_signal_to_target): Only deal with signal of the Windows OS ABI.

Make init_type/arch_type take a size in bits This changes the interfaces to init_type and arch_type to take the type length in bits as input (instead of as bytes). The routines assert that the length is a multiple of TARGET_CHAR_BIT. For consistency, arch_flags_type is changed likewise, so that now all type creation interfaces always use length in bits. All callers are updated in the straightforward manner. The assert actually found a bug in read_range_type, where the init_integer_type routine was called with a wrong argument (probably a bug introduced with the conversion to use init_integer_type). gdb/ChangeLog 2017-09-27 Ulrich Weigand <uweigand@de.ibm.com> * gdbtypes.c (init_type): Change incoming argument from length-in-bytes to length-in-bits.

Make init_type/arch_type take a size in bits This changes the interfaces to init_type and arch_type to take the type length in bits as input (instead of as bytes). The routines assert that the length is a multiple of TARGET_CHAR_BIT. For consistency, arch_flags_type is changed likewise, so that now all type creation interfaces always use length in bits. All callers are updated in the straightforward manner. The assert actually found a bug in read_range_type, where the init_integer_type routine was called with a wrong argument (probably a bug introduced with the conversion to use init_integer_type). gdb/ChangeLog 2017-09-27 Ulrich Weigand <uweigand@de.ibm.com> * gdbtypes.c (init_type): Change incoming argument from length-in-bytes to length-in-bits.

Add type for $_tlb->process_environment_block->process_parameters The type then looks like this: (gdb) pt $_tlb->process_environment_block->process_parameters type = struct rtl_user_process_parameters { DWORD32 maximum_length; DWORD32 length; DWORD32 flags; DWORD32 debug_flags; void *console_handle; DWORD32 console_flags; void *standard_input; void *standard_output; void *standard_error; unicode_string current_directory; void *current_directory_handle; unicode_string dll_path; unicode_string image_path_name; unicode_string command_line; void *environment; DWORD32 starting_x; DWORD32 starting_y; DWORD32 count_x; DWORD32 count_y; DWORD32 count_chars_x; DWORD32 count_chars_y; DWORD32 fill_attribute; DWORD32 window_flags; DWORD32 show_window_flags; unicode_string window_title; unicode_string desktop_info; unicode_string shell_info; unicode_string runtime_data; } * It's mainly useful to get the current directory, or the full command line: (gdb) p $_tlb->process_environment_block->process_parameters->current_directory $1 = { length = 26, maximum_length = 520, buffer = 0xe36c8 L"C:\\src\\tests\\" } (gdb) p $_tlb->process_environment_block->process_parameters->command_line $2 = { length = 94, maximum_length = 96, buffer = 0xe32aa L"\"C:\\gdb\\build64\\gdb-git\\gdb\\gdb.exe\" access.exe" } The type names are all lowercase because the existing types created by windows_get_tlb_type are also lowercase. Type unicode_string is documented at [1]. The official documentation [2] for rtl_user_process_parameters is limited, so I've used this other page [3].

Add casts to memory allocation related calls Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Change pid_to_str to return std::string Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files.

target_stack -> current_top_target() throughout The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

Change pid_to_str to return std::string Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files.

Per-inferior/Inferior-qualified thread IDs This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

/* Implement the "iterate_over_objfiles_in_search_order" gdbarch
method. It searches all objfiles, starting with CURRENT_OBJFILE
first (if not NULL).
On Windows, the system behaves a little differently when two
objfiles each define a global symbol using the same name, compared
to other platforms such as GNU/Linux for instance. On GNU/Linux,
all instances of the symbol effectively get merged into a single
one, but on Windows, they remain distinct.
As a result, it usually makes sense to start global symbol searches
with the current objfile before expanding it to all other objfiles.
This helps for instance when a user debugs some code in a DLL that
refers to a global variable defined inside that DLL. When trying
to print the value of that global variable, it would be unhelpful
to print the value of another global variable defined with the same
name, but in a different DLL. */

gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment. (cygwin_init_abi): New declaration. * windows-tdep.c: Split signal enumeration in two, one for Windows and one for Cygwin. (windows_gdb_signal_to_target): Only deal with signal of the Windows OS ABI.

This commit emulates WTERMSIG etc. by translating the fatal exception codes to more-or-less equivalent Posix signals. gdb/ChangeLog: 2020-01-06 Eli Zaretskii <eliz@gnu.org> Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add gdbsupport/gdb_wait.c. * windows-tdep.c: New enumeration of WINDOWS_SIG* signals. (windows_gdb_signal_to_target): New function, uses the above enumeration to convert GDB internal signal codes to equivalent Windows codes. (windows_init_abi): Call set_gdbarch_gdb_signal_to_target. * windows-nat.c: Include "gdb_wait.h". (get_windows_debug_event): Extract the fatal exception from the exit status and convert to the equivalent Posix signal number. * cli/cli-cmds.c (exit_status_set_internal_vars): Account for the possibility that WTERMSIG returns GDB_SIGNAL_UNKNOWN. * gdbsupport/gdb_wait.c: New file, implements windows_status_to_termsig. * gdbsupport/gdb_wait.h (WIFEXITED, WIFSIGNALED, WEXITSTATUS) (WTERMSIG) [__MINGW32__]: Separate definitions for MinGW. gdb/gdbserver/ChangeLog: 2020-01-06 Eli Zaretskii <eliz@gnu.org> Pedro Alves <palves@redhat.com> * win32-low.c (get_child_debug_event): Extract the fatal exception from the exit status and convert to the equivalent Posix signal number.

case GDB_SIGNAL_STOP:
gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment. (cygwin_init_abi): New declaration. * windows-tdep.c: Split signal enumeration in two, one for Windows and one for Cygwin. (windows_gdb_signal_to_target): Only deal with signal of the Windows OS ABI.

case GDB_SIGNAL_IO:
gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment.

case GDB_SIGNAL_PWR:
gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment.

gdb: stop using host-dependent signal numbers in windows-tdep.c The signal enumeration in windows-tdep.c is defined differently whether it is compiled on Cygwin or not. This is problematic, since the code in tdep files is not supposed to be influenced by the host platform (the platform GDB itself runs on). This makes a difference in windows_gdb_signal_to_target. An obvious example of clash is SIGABRT. Let's pretend we are cross-debugging a Cygwin process from a MinGW (non-Cygwin Windows) GDB. If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment. (cygwin_init_abi): New declaration. * windows-tdep.c: Split signal enumeration in two, one for Windows and one for Cygwin. (windows_gdb_signal_to_target): Only deal with signal of the Windows OS ABI.

If GDB needs to translate the gdb signal number GDB_SIGNAL_ABRT into a target equivalent, it would obtain the MinGW number (22), despite the target being a Cygwin process. Conversely, if debugging a MinGW process from a Cygwin-hosted GDB, GDB_SIGNAL_ABRT would be converted to a Cygwin signal number (6) despite the target being a MinGW process. This is wrong, since we want the result to depend on the target's platform, not GDB's platform. This known flaw was accepted because at the time we had a single OS ABI (called Cygwin) for all Windows binaries (Cygwin ones and non-Cygwin ones). This limitation is now lifted, as we now have separate Windows and Cygwin OS ABIs. This means we are able to detect at runtime whether the binary we are debugging is a Cygwin one or non-Cygwin one. This patch splits the signal enum in two, one for the MinGW flavors and one for Cygwin, removing all the ifdefs that made it depend on the host platform. It then makes two separate gdb_signal_to_target gdbarch methods, that are used according to the OS ABI selected at runtime. There is a bit of re-shuffling needed in how the gdbarch'es are initialized, but nothing major. gdb/ChangeLog: * windows-tdep.h (windows_init_abi): Add comment.

Teach GDB that wchar_t is a built-in type in C++ mode GDB is currently not aware that wchar_t is a built-in type in C++ mode. This is usually not a problem because the debug info describes the type, so when you have a program loaded, you don't notice this. However, if you try expressions involving wchar_t before a program is loaded, gdb errors out: (gdb) p (wchar_t)-1 No symbol table is loaded. Use the "file" command. (gdb) p L"hello" No type named wchar_t. (gdb) ptype L"hello" No type named wchar_t. This commit teaches gdb about the type. After: (gdb) p (wchar_t)-1 $1 = -1 L'\xffffffff' (gdb) p L"hello" $2 = L"hello" (gdb) ptype L"hello" type = wchar_t [6] Unlike char16_t/char32_t, unfortunately, the underlying type of wchar_t is implementation dependent, both size and signness. So this requires adding a couple new gdbarch hooks. I grepped the GCC code base for WCHAR_TYPE and WCHAR_TYPE_SIZE, and it seems to me that the majority of the ABIs have a 4-byte signed wchar_t, so that's what I made the default for GDB too. And then I looked for which ports have a 16-bit and/or unsigned wchar_t, and made GDB follow suit. gdb/ChangeLog: 2017-04-12 Pedro Alves <palves@redhat.com> PR gdb/21323 * c-lang.c (cplus_primitive_types) <cplus_primitive_type_wchar_t>: New enum value.

gdb: add back declarations for _initialize functions I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

Display ExceptionRecord for $_siginfo Uses the $_siginfo convenience variable to show the last exception. The type looks like this: (gdb) pt $_siginfo type = struct EXCEPTION_RECORD { DWORD ExceptionCode; DWORD ExceptionFlags; struct EXCEPTION_RECORD *ExceptionRecord; PVOID ExceptionAddress; DWORD NumberParameters; ULONG_PTR ExceptionInformation[15]; } EXCEPTION_RECORD is documented at [1]. Example: Program received signal SIGSEGV, Segmentation fault. main () at crasher.c:4 4 *(int*)0x123 = 0; (gdb) p $_siginfo $1 = { ExceptionCode = 3221225477, ExceptionFlags = 0, ExceptionRecord = 0x0, ExceptionAddress = 0x401632 <main+18>, NumberParameters = 2, ExceptionInformation = {1, 291, 0 <repeats 13 times>} } (gdb) p/x $_siginfo.ExceptionCode $2 = 0xc0000005 (gdb) p/x $_siginfo.ExceptionInformation[1] $3 = 0x123 And 0xc0000005 is the value of EXCEPTION_ACCESS_VIOLATION.
