2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers1-2/+2
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

2019-07-09Rename common to gdbsupportTom Tromey1-4/+4
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-07-08Fix breakpoints on file reloads for PIE binariesAlan Hayward1-0/+12
When a binary is built using PIE, reloading the file will cause GDB to error on restart. For example: gdb ./a.out (gdb) break main (gdb) run (gdb) file ./a.out (gdb) continue Will cause GDB to error with: Continuing. Warning: Cannot insert breakpoint 1. Cannot access memory at address 0x9e0 Command aborted. This is due to the symbol offsets not being relocated after reloading the file. Fix is to ensure solib_create_inferior_hook is called, in the same manner as infrun.c:follow_exec(). Expand the idempotent test to cover PIE scenarios. gdb/ChangeLog: * symfile.c (symbol_file_command): Call solib_create_inferior_hook. gdb/testsuite/ChangeLog: * gdb.base/break-idempotent.exp: Test both PIE and non PIE.

2019-06-04Introduce and use make_unique_xstrdupPedro Alves1-1/+1
Adds an utility function to make it shorter to write the common case of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it throughout. Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet. I tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but that doesn't work because gdb_unique_ptr.h depends on common-utils.h for xfree. gdb/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * common/gdb_unique_ptr.h (make_unique_xstrdup): New. * ada-lang.c (catch_ada_completer): Use make_unique_xstrdup. * breakpoint.c (condition_completer): Likewise. * cli/cli-dump.c (scan_expression): Likewise. * common/filestuff.c (mkdir_recursive): Likewise. * common/gdb_tilde_expand.c (gdb_tilde_expand_up) * common/pathstuff.c (gdb_realpath, gdb_realpath_keepfile) (gdb_abspath): Likewise. * compile/compile-cplus-types.c (compile_cplus_instance::decl_name): Likewise. * completer.c (complete_explicit_location): (signal_completer, reg_or_group_completer_1): Likewise. * cp-support.c (cp_remove_params_if_any): Likewise. * fbsd-tdep.c (fbsd_core_vnode_path): Likewise. * guile/scm-safe-call.c (gdbscm_safe_eval_string): Likewise. * infcmd.c (strip_bg_char): Likewise. * linespec.c (copy_token_string): Likewise. * mi/mi-main.c (output_cores): Likewise. * psymtab.c (psymtab_search_name): * symfile.c (test_set_ext_lang_command): Likewise. * target.c (target_fileio_read_stralloc): Likewise. * tui/tui-regs.c (tui_reggroup_completer): Likewise. * value.c (complete_internalvar): Likewise. gdb/gdbserver/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * server.c (captured_main): Use make_unique_xstrdup.
2019-05-03Fix lookup of separate debug file on MS-Windows.Eli Zaretskii1-0/+22
If you put the separate debug file in a global debug directory, GDB on MS-Windows would fail to find it. This happens because we obtain the directory to look up the debug file by concatenating the debug directory name with the leading directories of the executable, and the latter includes the drive letter on MS-Windows. So we get an invalid file name like d:/usr/lib/debug/d:/usr/bin/foo.debug This commit fixes that by removing the colon of the drive letter, thus producing d:/usr/lib/debug/d/usr/bin/foo.debug gdb/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * symfile.c (find_separate_debug_file): Remove colon from the drive spec of DOS/Windows file names of the target, so that the file name produced from DEBUGDIR and the target's directory will be valid on DOS/Windows systems. gdb/doc/ChangeLog: 2019-05-03 Eli Zaretskii <eliz@gnu.org> * gdb.texinfo (Separate Debug Files): Document how the subdirectory of the global debug directory is computed on MS-Windows/MS-DOS.
2019-04-19Make objfile::static_links an htab_upTom Tromey1-1/+1
This changes objfile::static_links to be an htab_up, so that ~objfile no longer has to explicitly destroy it. Tested by the buildbot. gdb/ChangeLog 2019-04-19 Tom Tromey <tom@tromey.com> * symfile.c (reread_symbols): Update. * objfiles.c (objfile_register_static_link) (objfile_lookup_static_link): Update (~objfile) Don't delete static_links. * objfiles.h (struct objfile) <static_links>: Now an htab_up.

2019-03-23Have parser reset the innermost block trackerTom Tromey1-6/+0
I ran across a comment in symfile.c today: /* Clear globals which might have pointed into a removed objfile. FIXME: It's not clear which of these are supposed to persist between expressions and which ought to be reset each time. */ It seems to me that this can be clarified: the parser entry points ought to reset the innermost block tracker (and the expression context block), and these should not be considered valid for code to use at arbitrary times -- only immediately after an expression has been parsed.

2019-02-12Try to use the canonical version of a sysroot for debug file links.John Baldwin1-3/+10
Object file paths passed to find_separate_debug_file are always canonical paths with symbolic links resolved. If a sysroot path traverses a symbolic link, it will not match the object file paths. Generate a canonical version of the sysroot directory. If it is valid, use it instead of gdb_sysroot with child_path to determine if an object file is under a system root. gdb/ChangeLog: * symfile.c (find_separate_debug_file): Use canonical path of sysroot with child_path instead of gdb_sysroot if it is valid.
2019-02-12Use child_path to determine if an object file is under a sysroot.John Baldwin1-5/+7
This fixes the case where the sysroot happens to end in a trailing '/'. Note that the path returned from child_path always skips over the directory separator at the start of the base path, so a separator must always be explicitly added before the base path. gdb/ChangeLog: * symfile.c (find_separate_debug_file): Use child_path to determine if an object file is under a sysroot.
2019-02-12Look for separate debug files in debug directories under a sysroot.John Baldwin1-2/+15
When an object file is present in a system root, GDB currently looks for separate debug files under the global debugfile directories. For example, if the sysroot is set to "/myroot" and hte global debugfile directory is set to "/usr/lib/debug", GDB will look for a separate debug file for "/myroot/lib/libc.so.7" in the following paths: /myroot/lib/libc.so.7.debug /myroot/lib/.debug/libc.so.7.debug /usr/lib/debug//myroot/lib/libc.so.7.debug /usr/lib/debug/lib/libc.so.7.debug However, some system roots include a full system installation including a nested global debugfile directory under the sysroot. This patch adds an additional check to support such systems. In the example above the additional path searched is: /myroot/usr/lib/debug/lib/libc.so.7.debug To try to preserve existing behavior as much as possible, this new path is searched last for each global debugfile directory. gdb/ChangeLog: * symfile.c (find_separate_debug_file): Look for separate debug files in debug directories under the sysroot.

2019-01-10Introduce objfile::reset_psymtabsTom Tromey1-11/+1
This introduces a new method, objfile::reset_psymtabs, and changes reread_symbols to use it. This method simply destroys the existing partial symbols and recreates the psymtab_storage object. This patch fixes a latent bug -- namely, that reread_symbols should clear objfile::psymbol_map, but does not. I can submit that separately if you'd prefer. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * symfile.c (reread_symbols): Call objfile->reset_psymtabs. * objfiles.h (objfile::reset_psymtabs): New method.
2019-01-10Introduce class psymtab_storageTom Tromey1-7/+7
This introduces a new psymtab_storage class, which holds all psymbol-related objects that are independent of the objfile. (This latter contraint explains why psymbol_map was not moved; though this could still be done with some work.) This patch does not yet change where psymtab allocation is done -- that comes later. This just wraps everything in a single object to make further transformations simpler. Note that a shared_ptr is used to link from the objfile to the psymtab_storage object. The end goal here is to allow a given symbol reader to simply attach to the psymtab_storage object to the BFD, then reuse it in later invocations; shared_ptr makes this simple to reason about. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * symmisc.c (print_symbol_bcache_statistics): Update.

The special code in this macro for noticing a "break" from the inner loop was only needed in a single place; so rather than try to replicate this, I've simply replaced that use with a "goto". gdb/ChangeLog 2019-01-09 Tom Tromey <tom@tromey.com> * symfile.c (overlay_invalidate_all, find_pc_overlay) (find_pc_mapped_section, list_overlays_command) (map_overlay_command, unmap_overlay_command) (simple_overlay_update): Use all_objfiles. * spu-tdep.c (spu_overlay_update): Use all_objfiles. * printcmd.c (info_symbol_command): Use all_objfiles. * objfiles.h (ALL_OBJSECTIONS): Remove. * maint.c (maintenance_translate_address): Use all_objfiles. * gcore.c (gcore_create_callback): Use all_objfiles.

2019-01-02Fix search of debug files for remote debuggeeAndrey Utkin1-3/+7
When using remote debugging server, and when debuggee filename is inferred via qXfer:exec-file:read request, or sysroot starts with "target:", this "target:" prefix of filepaths is not treated correctly during debug file search - it appears in the middle of the looked up paths. In the following example, unpatched GDB can't find separate debug files for neither the executable, nor standard libraries: $ gdb -ex 'set debug separate-debug-file 1' -ex 'set sysroot target:/' -ex 'set debug-file-directory /usr/lib/debug:/home/j/hide' -ex 'target remote :3333' -ex 'break main' -ex 'continue' -ex 'bt' -ex 'info sharedlibrary' -ex 'set confirm off' -ex 'quit' GNU gdb (Gentoo 9999 vanilla) 8.2.50.20181109-git Copyright (C) 2018 Free Software Foundation, Inc.

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2018-12-26Improve "set debug separate-debug-file"Simon Marchi1-5/+34
"set debug separate-debug-file" shows which candidates are considered, when trying to find separate debug info. But it's not clear if GDB used a certain candidate, and if not, why not.

2018-10-19Clear static_links in reread_symbolsTom Tromey1-0/+1
-fsanitize=address pointed out a use-after free in objfile_register_static_link. The bug turned out to be that reread_symbols does not clear the static_links field; this leaves a hash table that is filled with freed pointers. Jan's (now quite old) idea of replacing reread_symbols with a simple delete/new still seems good to me, and it's worth noting that it would have avoided this bug. Tested by the buildbot and by observing the change with -fsanitize=address. gdb/ChangeLog 2018-10-19 Tom Tromey <tom@tromey.com> * symfile.c (reread_symbols): Clear "static_links".
2018-10-04Simplify complaints even moreTom Tromey1-4/+4
This removes the SHORT_FIRST_MESSAGE case from complaints, leaving only a single case. This allows for the removal of the last argument to clear_complaints, and also simplifies complaint_internal, removing an extra allocation in the process. After this, the "./gdb -iex 'set complaint 1' -nx ./gdb" example will show: Reading symbols from ./gdb... During symbol reading: .debug_ranges entry has start address of zero [in module /home/tromey/gdb/build/gdb/gdb] During symbol reading: DW_AT_low_pc 0x0 is zero for DIE at 0x17116c1 [in module /home/tromey/gdb/build/gdb/gdb] During symbol reading: .debug_line address at offset 0xa22f5 is 0 [in module /home/tromey/gdb/build/gdb/gdb] During symbol reading: unsupported tag: 'DW_TAG_unspecified_type' During symbol reading: const value length mismatch for 'std::ratio<1, 1000000000>::num', got 8, expected 0 This is a bit wordier but, I think, a bit more clear, as the form of the message no longer depends on precisely when it was emitted. In particular if you compare to the output from the 'Clean up "Reading symbols" output' patch, you can see that earlier gdb would switch from the prefix-less form to the "During symbol reading" form at a point that is meaningless to the user (specifically, after psymtab reading is done and gdb tries to expand a CU). 2018-10-04 Tom Tromey <tom@tromey.com> * symfile.c (syms_from_objfile_1, finish_new_objfile) (reread_symbols): Update. * complaints.h (clear_complaints): Remove argument. * complaints.c (enum complaint_series): Remove.

2018-10-04Only print "no debugging symbols" message onceTom Tromey1-1/+6
The "no debugging symbols" message can be confusing in some cases, for example when gdb finds separate debug info for an objfile, but the separate debug info does not contain symbols. For example: (gdb) file /bin/ls Reading symbols from /bin/ls... Reading symbols from .gnu_debugdata for /usr/bin/ls... (No debugging symbols found in .gnu_debugdata for /usr/bin/ls) (No debugging symbols found in /bin/ls) Here, I think the second "no debugging symbols" message is redundant and confusing. This patch changes gdb to only emit this message when the objfile in question does not have a separate debug file. So, in the example above, the output would now read: (gdb) file /bin/ls Reading symbols from /bin/ls... Reading symbols from .gnu_debugdata for /usr/bin/ls... (No debugging symbols found in .gnu_debugdata for /usr/bin/ls) 2018-10-04 Tom Tromey <tom@tromey.com> * symfile.c (symbol_file_add_with_addrs): Do not print "no debugging symbols" message if there is a separate debug objfile.
2018-10-04Clean up "Reading symbols" outputTom Tromey1-17/+3
This patch is another attempt to fix PR cli/19551. Unlike my previous attempt, it doesn't print progress. Instead, it just changes some messages and adds newlines to make the output a bit nicer. It also removes the "done." text that was previously emitted. The idea here is that it is obvious when gdb is done reading debug info, as it starts then doing something else; and that while this message did not provide much benefit to users, it did make it harder to make the output clean. After this change the output from "./gdb -iex 'set complaint 1' -nx ./gdb" reads: Reading symbols from ./gdb... .debug_ranges entry has start address of zero [in module /home/tromey/gdb/build/gdb/gdb] DW_AT_low_pc 0x0 is zero for DIE at 0x17116c1 [in module /home/tromey/gdb/build/gdb/gdb] .debug_line address at offset 0xa22f5 is 0 [in module /home/tromey/gdb/build/gdb/gdb] During symbol reading, unsupported tag: 'DW_TAG_unspecified_type'.

2018-10-04Use filtered printing when reading symbolsTom Tromey1-25/+25
While working on this series, I found some unfiltered prints that didn't make sense -- many things, like complaints, are filtered, while their context (in this case the "Reading symbols ..." messages) may not be. This patch changes some spots in symbol reading to use filtered prints. I think this is preferable overall; in fact I'd go farther and say that unfiltered printing should just be removed. One of these spots was not strictly related (the change to dump_psymtab), but I left it in partly because it makes psymtab.c "unfiltered-clean", and partly because it is an example of filtered and unfiltered printing being mixed in the same function. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * symfile.c (symbol_file_add_with_addrs, symbol_file_clear) (separate_debug_file_exists, find_separate_debug_file) (add_symbol_file_command, reread_symbols, allocate_symtab) (allocate_compunit_symtab): Use filtered printing, not unfiltered. * psymtab.c (require_partial_symbols, dump_psymtab) (allocate_psymtab): Use filtered printing, not unfiltered.

There is also a similar option for "symbol-file". gdb/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * symfile.c (add_symbol_file_command, _initialize_symfile): Add option "-o" to add-symbol-file-load to add an offset to each section's load address. * symfile.c (set_objfile_default_section_offset): New function. gdb/doc/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * gdb.texinfo (Files): Document "add-symbol-file -o offset". gdb/testsuite/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * gdb.base/relocate.exp: Add test for "add-symbol-file -o ".
2018-06-28Make sure that sorting does not change section orderPetr Tesarik1-2/+9
Symbol files may contain multiple sections with the same name. Section addresses specified by add-symbol-file are assigned to the corresponding BFD sections in addr_info_make_relative using sorted indexes of both vectors. Since the sort algorithm is not inherently stable, the comparison function uses sectindex to maintain the original order. However, add_symbol_file_command uses zero for all sections, so if the user specifies multiple sections with the same name, they will be assigned randomly to symbol file sections with the same name. gdb/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * symfile.c (add_symbol_file_command): Make sure that sections
2018-06-28Make add-symbol-file's address argument optionalPetr Tesarik1-14/+13
The (first) .text section must be always specified as the second non-option argument. The documentation states that GDB cannot figure out this address by itself. This is true if the object file was indeed relocated, but it is also confusing, because all other sections can be omitted and will use the address provided by BFD. gdb/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * symfile.c (add_symbol_file_command, _initialize_symfile): Do not require the second argument. If omitted, load sections at the addresses specified in the file. gdb/doc/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * gdb.texinfo (Files): The address argument for "add-symbol-file" is no longer mandatory. gdb/testsuite/ChangeLog: 2018-06-28 Petr Tesarik <ptesarik@suse.cz> * gdb.base/relocate.exp: Test add-symbol-file behavior when the address argument is omitted.

2018-06-07target_stack -> current_top_target() throughoutPedro Alves1-1/+1
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.

2018-05-23Remove symfile_complaintsTom Tromey1-4/+4
The complaint system seems to allow for multiple different complaint topics. However, in practice only symfile_complaints has ever been defined. Seeing that complaints.c dates to 1992, and that no new complaints have been added in the intervening years, I think it is reasonable to admit that complaints are specifically related to debuginfo reading. This patch removes symfile_complaints and updates all the callers. Some of these spots should perhaps be calls to warning instead, but I did not make that change. gdb/ChangeLog 2018-05-23 Tom Tromey <tom@tromey.com> * complaints.c (symfile_complaints): Remove.

2018-05-16Use a distinguishing name for minidebug objfileTom Tromey1-2/+5
One part of PR cli/19551 is that the mini debug info objfile reuses the name of the main objfile from which it comes. This can be seen because gdb claims to be reading symbols from the same file two times, like: Reading symbols from /bin/gdb...Reading symbols from /bin/gdb...(no debugging symbols found)...done. I think this would be less confusing if the minidebug objfile were given a different name. That is what this patch implements. It also arranges for the minidebug objfile to be marked OBJF_NOT_FILENAME. After this patch the output looks like: Reading symbols from /bin/gdb...Reading symbols from .gnu_debugdata for /usr/libexec/gdb...(no debugging symbols found)...done.

2018-05-03Convert struct target_ops to C++Pedro Alves1-1/+1
I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.
