Rename common to gdbsupport 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. *

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function. Regression tested on the buildbot. gdb/ChangeLog 2018-03-19 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * unittests/observable-selftests.c: New file. * common/observable.h: New file. * observable.h: New file. * ada-lang.c, ada-tasks.c, agent.c, aix-thread.c, annotate.c, arm-tdep.c, auto-load.c, auxv.c, break-catch-syscall.c, breakpoint.c, bsd-uthread.c, cli/cli-interp.c, cli/cli-setshow.c, corefile.c, dummy-frame.c, event-loop.c, event-top.c, exec.c, extension.c, frame.c, gdbarch.c, guile/scm-breakpoint.c, infcall.c, infcmd.c, inferior.c, inflow.c, infrun.c, jit.c, linux-tdep.c, linux-thread-db.c, m68klinux-tdep.c, mi/mi-cmd-break.c, mi/mi-interp.c, mi/mi-main.c, objfiles.c, ppc-linux-nat.c, ppc-linux-tdep.c, printcmd.c, procfs.c, python/py-breakpoint.c, python/py-finishbreakpoint.c, python/py-inferior.c, python/py-unwind.c, ravenscar-thread.c, record-btrace.c, record-full.c, record.c, regcache.c, remote.c, riscv-tdep.c, sol-thread.c, solib-aix.c, solib-spu.c, solib.c, spu-multiarch.c, spu-tdep.c, stack.c, symfile-mem.c, symfile.c, symtab.c, thread.c, top.c, tracepoint.c, tui/tui-hooks.c, tui/tui-interp.c, valops.c: Update all users. * tui/tui-hooks.c (tui_bp_created_observer) (tui_bp_deleted_observer, tui_bp_modified_observer) (tui_inferior_exit_observer, tui_before_prompt_observer) (tui_normal_stop_observer, tui_register_changed_observer): Remove.

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. *

Global variable GDB_SYSROOT is used as a prefix directory
to search for binary files if they have an absolute path.
If GDB_SYSROOT starts with "target:" and target filesystem
is the local filesystem then the "target:" prefix will be
stripped before the search starts. This ensures that the
same search algorithm is used for local files regardless of
whether a "target:" prefix was used.
Global variable SOLIB_SEARCH_PATH is used as a prefix directory
(or set of directories, as in LD_LIBRARY_PATH) to search for all
shared libraries if not found in either the sysroot (if set) or
the local filesystem. SOLIB_SEARCH_PATH is not used when searching
for the main executable.
Search algorithm:
* If a sysroot is set and path is absolute:
* Search for sysroot/path.
* else
* Look for it literally (unmodified).
* If IS_SOLIB is non-zero:
* Look in SOLIB_SEARCH_PATH.
* If available, use target defined search function.
* If NO sysroot is set, perform the following two searches:
* Look in inferior's $PATH.
* If IS_SOLIB is non-zero:
* Look in inferior's $LD_LIBRARY_PATH.

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.

Fix regular /path/to/directory sysroots and target reported dll paths with drive specs. I tried debugging a remote Windows program on Linux host, and pointed the sysroot to "/some/path/" rather than "remote:", and I found GDB couldn't find the dlls in the sysroot. If the dll name is "C:/Windows/system32/ntdll.dll", I end up with the sysroot+in_pathname concatenated this way: (top-gdb) p temp_pathname $1 = 0x228b690 "/some/pathC:/Windows/system32/ntdll.dll" ^^ That is, a directory separator is missing. This is a regression. The problem is that solib_find decides that since the target path has a drive spec, a separator is not necessary, which is clearly wrong in this case. That check was added in <https://sourceware.org/ml/gdb-patches/2013-06/msg00028.html>, to handle the case of sysroot being "remote:". This patch fixes that original issue in a different way. Instead of checking whether the path has a drive spec, check whether the sysroot is "remote:". The patch adds a table that helps visualize the cases that need a separator. I also confirmed the original issue is still handled as expected. That is, that "set sysroot remote:" still does the right thing. remote_filename_p returns true if the filename is prefixed with "remote:". In this case, we need to check whether the filename is exactly "remote:". I thought of different ways or either changing remote_filename_p or adding another convenience function to remote.c to avoid exposing the "remote:" prefix out of remote.c. But all attempts turned out adding lot of over needless complication. So the patch just exposes the prefix behind a new macro, which allows using a straighforward strcmp. gdb/ 2013-09-27 Pedro Alves <palves@redhat.com> * remote.h (REMOTE_SYSROOT_PREFIX): New define. (remote_filename_p): Add comment. * remote.c (remote_filename_p): Adjust to use REMOTE_SYSROOT_PREFIX. * solib.c (solib_find): When deciding whether we need to add a directory separator, check whether the sysroot is "remote:" instead of checking whether the patch has a drive spec. Add comments.

Fix regular /path/to/directory sysroots and target reported dll paths with drive specs. I tried debugging a remote Windows program on Linux host, and pointed the sysroot to "/some/path/" rather than "remote:", and I found GDB couldn't find the dlls in the sysroot. If the dll name is "C:/Windows/system32/ntdll.dll", I end up with the sysroot+in_pathname concatenated this way: (top-gdb) p temp_pathname $1 = 0x228b690 "/some/pathC:/Windows/system32/ntdll.dll" ^^ That is, a directory separator is missing. This is a regression. The problem is that solib_find decides that since the target path has a drive spec, a separator is not necessary, which is clearly wrong in this case. That check was added in <https://sourceware.org/ml/gdb-patches/2013-06/msg00028.html>, to handle the case of sysroot being "remote:". This patch fixes that original issue in a different way. Instead of checking whether the path has a drive spec, check whether the sysroot is "remote:". The patch adds a table that helps visualize the cases that need a separator. I also confirmed the original issue is still handled as expected. That is, that "set sysroot remote:" still does the right thing. remote_filename_p returns true if the filename is prefixed with "remote:". In this case, we need to check whether the filename is exactly "remote:". I thought of different ways or either changing remote_filename_p or adding another convenience function to remote.c to avoid exposing the "remote:" prefix out of remote.c. But all attempts turned out adding lot of over needless complication. So the patch just exposes the prefix behind a new macro, which allows using a straighforward strcmp. gdb/ 2013-09-27 Pedro Alves <palves@redhat.com> * remote.h (REMOTE_SYSROOT_PREFIX): New define.

IOW, we don't need to add a separator if IN_PATHNAME already
has one, or when the sysroot is exactly "target:".

C++ify gdb/common/environ.c As part of the preparation necessary for my upcoming task, I'd like to propose that we turn gdb_environ into a class. The approach taken here is simple: the class gdb_environ contains everything that is needed to manipulate the environment variables. These variables are stored in an std::vector<char *>, which can be converted to a 'char **' and passed as argument to functions that need it. The usage has not changed much. As per Pedro's suggestion, this class uses a static factory method initialization. This means that when an instance is created, it is initially empty. When needed, it has to be initialized using the static method 'from_host_environ'. As mentioned before, this is a preparation for an upcoming work that I will be posting in the next few weeks or so. For that work, I'll probably create another data structure that will contain all the environment variables that were set by the user using the 'set environment' command, because I'll need access to them.

PR 20569, segv in follow_exec The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing. Tested on x86_64 Fedora 23, native and gdbserver. gdb/ChangeLog: 2016-10-25 Sandra Loosemore <sandra@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> Pedro Alves <palves@redhat.com> PR gdb/20569 * exceptions.c (exception_print_same): Moved here from exec.c. * exceptions.h (exception_print_same): Declare. * exec.h: Include "symfile-add-flags.h".

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.

PR 20569, segv in follow_exec The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing.

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.

Use class to manage BFD reference counts This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts.

Use class to manage BFD reference counts This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

Use class to manage BFD reference counts This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

Make symfile_add_flags and objfile->flags strongly typed This makes these flag types be "enum flag" types.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

catch (const gdb_exception_error &e)
Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception. Now an exception value. <mask>: Delete field. (exceptions_state_mc_init): Remove all parameters. Adjust. (exceptions_state_mc): No longer pop the catcher here.

Eliminate catch_errors If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

Eliminate catch_errors If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

catch (const gdb_exception_error &e)
Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception. Now an exception value. <mask>: Delete field. (exceptions_state_mc_init): Remove all parameters. Adjust. (exceptions_state_mc): No longer pop the catcher here.

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

Make symfile_add_flags and objfile->flags strongly typed This makes these flag types be "enum flag" types. The benefit is making use of C++'s stronger typing -- mixing the flags types by mistake errors at compile time.

try
Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception. Now an exception value. <mask>: Delete field. (exceptions_state_mc_init): Remove all parameters. Adjust. (exceptions_state_mc): No longer pop the catcher here. (exceptions_state_mc_catch): New function. (throw_exception): Adjust. * common/common-exceptions.h (exceptions_state_mc_init): Remove all parameters. (exceptions_state_mc_catch): Declare. (TRY_CATCH): Rename to ... (TRY): ... this. Remove EXCEPTION and MASK parameters. (CATCH, END_CATCH): New. All callers adjusted. gdb/gdbserver/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> Adjust all callers of TRY_CATCH to use TRY/CATCH/END_CATCH instead.

Make symfile_add_flags and objfile->flags strongly typed This makes these flag types be "enum flag" types. The benefit is making use of C++'s stronger typing -- mixing the flags types by mistake errors at compile time. This caught one old bug in symbol_file_add_main_1 already, fixed by this patch as well: @@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags) what is frameless. */ reinit_frame_cache (); - if ((flags & SYMFILE_NO_READ) == 0) + if ((add_flags & SYMFILE_NO_READ) == 0) set_initial_language (); } Above, "flags" are objfile flags, not symfile_add_flags. So that was actually checking for "flag & OBJF_PSYMTABS_READ", which has the same value as SYMFILE_NO_READ... I moved the flags definitions to separate files to break circular dependencies.

MIPS: Keep the ISA bit in compressed code addresses 1. Background information The MIPS architecture, as originally designed and implemented in mid-1980s has a uniform instruction word size that is 4 bytes, naturally aligned. As such all MIPS instructions are located at addresses that have their bits #1 and #0 set to zeroes, and any attempt to execute an instruction from an address that has any of the two bits set to one causes an address error exception. This may for example happen when a jump-register instruction is executed whose register value used as the jump target has any of these bits set. Then in mid 1990s LSI sought a way to improve code density for their TinyRISC family of MIPS cores and invented an alternatively encoded instruction set in a joint effort with MIPS Technologies (then a subsidiary of SGI). The new instruction set has been named the MIPS16 ASE (Application-Specific Extension) and uses a variable instruction word size, which is 2 bytes (as the name of the ASE suggests) for most, but there are a couple of exceptions that take 4 bytes, and then most of the 2-byte instructions can be treated with a 2-byte extension prefix to expand the range of the immediate operands used. As a result instructions are no longer 4-byte aligned, instead they are aligned to a multiple of 2. That left the bit #0 still unused for code references, be it for the standard MIPS (i.e. as originally invented) or for the MIPS16 instruction set, and based on that observation a clever trick was invented that on one hand allowed the processor to be seamlessly switched between the two instruction sets at any time at the run time while on the other avoided the introduction of any special control register to do that. So it is the bit #0 of the instruction address that was chosen as the selector and named the ISA bit. Any instruction executed at an even address is interpreted as a standard MIPS instruction (the address still has to have its bit #1 clear), any instruction executed at an odd address is interpreted as a MIPS16 instruction. To switch between modes ordinary jump instructions are used, such as used for function calls and returns, specifically the bit #0 of the source register used in jump-register instructions selects the execution (ISA) mode for the following piece of code to be interpreted in. Additionally new jump-immediate instructions were added that flipped the ISA bit to select the opposite mode upon execution. They were considered necessary to avoid the need to make register jumps in all cases as the original jump-immediate instructions provided no way to change the bit #0 at all. This was all important for cases where standard MIPS and MIPS16 code had to be mixed, either for compatibility with the existing binary code base or to access resources not reachable from MIPS16 code (the MIPS16 instruction set only provides access to general-purpose registers, and not for example floating-point unit registers or privileged coprocessor 0 registers) -- pieces of code in the opposite mode can be executed as ordinary subroutine calls. A similar approach has been more recently adopted for the MIPS16 replacement instruction set defined as the so called microMIPS ASE. This is another instruction set encoding introduced to the MIPS architecture. Just like the MIPS16 ASE, the microMIPS instruction set uses a variable-length encoding, where each instruction takes a multiple of 2 bytes. The ISA bit has been reused and for microMIPS-capable processors selects between the standard MIPS and the microMIPS mode instead. 2. Statement of the problem To put it shortly, MIPS16 and microMIPS code pointers used by GDB are different to these observed at the run time. This results in the same expressions being evaluated producing different results in GDB and in the program being debugged. Obviously it's the results obtained at the run time that are correct (they define how the program behaves) and therefore by definition the results obtained in GDB are incorrect. A bit longer description will record that obviously at the run time the ISA bit has to be set correctly (refer to background information above if unsure why so) or the program will not run as expected. This is recorded in all the executable file structures used at the run time: the dynamic symbol table (but not always the static one!), the GOT, and obviously in all the addresses embedded in code or data of the program itself, calculated by applying the appropriate relocations at the static link time. While a program is being processed by GDB, the ISA bit is stripped off from any code addresses, presumably to make them the same as the respective raw memory byte address used by the processor to access the instruction in the instruction fetch access cycle. This stripping is actually performed outside GDB proper, in BFD, specifically _bfd_mips_elf_symbol_processing (elfxx-mips.c, see the piece of code at the very bottom of that function, starting with an: "If this is an odd-valued function symbol, assume it's a MIPS16 or microMIPS one." comment). This function is also responsible for symbol table dumps made by `objdump' too, so you'll never see the ISA bit reported there by that tool, you need to use `readelf'. This is however unlike what is ever done at the run time, the ISA bit once present is never stripped off, for example a cast like this: (short *) main will not strip the ISA bit off and if the resulting pointer is intended to be used to access instructions as data, for example for software instruction decoding (like for fault recovery or emulation in a signal handler) or for self-modifying code then the bit still has to be stripped off by an explicit AND operation. This is probably best illustrated with a simple real program example. Let's consider the following simple program: $ cat foobar.c int __attribute__ ((mips16)) foo (void) { return 1; } int __attribute__ ((mips16)) bar (void) { return 2; } int __attribute__ ((nomips16)) foo32 (void) { return 3; } int (*foo32p) (void) = foo32; int (*foop) (void) = foo; int fooi = (int) foo; int main (void) { return foop (); } $ This is plain C with no odd tricks, except from the instruction mode attributes. They are not necessary to trigger this problem, I just put them here so that the program can be contained in a single source file and to make it obvious which function is MIPS16 code and which is not. Let's try it with Linux, so that everyone can repeat this experiment: $ mips-linux-gnu-gcc -mips16 -g -O2 -o foobar foobar.c $ Let's have a look at some interesting symbols: $ mips-linux-gnu-readelf -s foobar | egrep 'table|foo|bar' Symbol table '.dynsym' contains 7 entries: Symbol table '.symtab' contains 95 entries: 55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c 66: 0040068c 4 FUNC GLOBAL DEFAULT [MIPS16] 12 bar 68: 00410848 4 OBJECT GLOBAL DEFAULT 21 foo32p 70: 00410844 4 OBJECT GLOBAL DEFAULT 21 foop 78: 00400684 8 FUNC GLOBAL DEFAULT 12 foo32 80: 00400680 4 FUNC GLOBAL DEFAULT [MIPS16] 12 foo 88: 00410840 4 OBJECT GLOBAL DEFAULT 21 fooi $ Hmm, no sight of the ISA bit, but notice how foo and bar (but not foo32!) have been marked as MIPS16 functions (ELF symbol structure's `st_other' field is used for that). So let's try to run and poke at this program with GDB. I'll be using a native system for simplicity (I'll be using ellipses here and there to remove unrelated clutter): $ ./foobar $ echo $? 1 $ So far, so good. $ gdb ./foobar [...] (gdb) break main Breakpoint 1 at 0x400490: file foobar.c, line 23. (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) Yay, it worked!

(gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) Actually we do not like to run foo here at all. Let's run bar instead! (gdb) set foop = bar (gdb) print foop $10 = (int (*)(void)) 0x40068c <bar> (gdb) Hmm, no ISA bit. Is it going to work?

(gdb) continue Continuing. Program terminated with signal SIGILL, Illegal instruction. The program no longer exists. (gdb) So let's try something else: (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) set foop = foo (gdb) advance foo foo () at foobar.c:4 4 } (gdb) disassemble Dump of assembler code for function foo: => 0x00400680 <+0>: jr ra 0x00400682 <+2>: li v0,1 End of assembler dump.

However it's not always right for some reason, I don't have a small test case to show it, but here's an excerpt from MIPS16 libc, a prologue of a function: 00019630 <__libc_init_first>: 19630: e8a0 jrc ra 19632: 6500 nop 00019634 <_init>: 19634: f000 6a11 li v0,17 19638: f7d8 0b08 la v1,15e00 <_DYNAMIC+0x15c54> 1963c: f400 3240 sll v0,16 19640: e269 addu v0,v1 19642: 659a move gp,v0 19644: 64f6 save 48,ra,s0-s1 19646: 671c move s0,gp 19648: d204 sw v0,16(sp) 1964a: f352 984c lw v0,-27828(s0) 1964e: 6724 move s1,a0 and the corresponding DWARF-2 line info: Line Number Statements: Extended opcode 2: set Address to 0x19631 Advance Line by 44 to 45 Copy Special opcode 8: advance Address by 0 to 0x19631 and Line by 3 to 48 Special opcode 66: advance Address by 4 to 0x19635 and Line by 5 to 53 Advance PC by constant 17 to 0x19646 Special opcode 25: advance Address by 1 to 0x19647 and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 33: advance Address by 2 to 0x19649 and Line by 0 to 53 Special opcode 39: advance Address by 2 to 0x1964b and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 61: advance Address by 4 to 0x1964f and Line by 0 to 53 -- see that "Advance PC by constant 17" there? It clears the ISA bit, however code at 0x19646 is not standard MIPS code at all. For some reason the constant is always 17, I've never seen DW_LNS_const_add_pc used with any other value -- is that a binutils bug or what? 3. Solution: I think we should retain the value of the ISA bit in code references, that is effectively treat them as cookies as they indeed are (although trivially calculated) rather than raw memory byte addresses. In a perfect world both the static symbol table and the respective DWARF-2 records should be fixed to include the ISA bit in all the cases. I think however that this is infeasible. All the uses of `_bfd_mips_elf_symbol_processing' can not necessarily be tracked down. This function is used by `elf_slurp_symbol_table' that in turn is used by `bfd_canonicalize_symtab' and `bfd_canonicalize_dynamic_symtab', which are public interfaces. Similarly DWARF-2 records are used outside GDB, one notable if a bit questionable is the exception unwinder (libgcc/unwind-dw2.c) -- I have identified at least bits in `execute_cfa_program' and `uw_frame_state_for', both around the calls to `_Unwind_IsSignalFrame', that would need an update as they effectively flip the ISA bit freely; see also the comment about MASK_RETURN_ADDR in gcc/config/mips/mips.h. But there may be more places. Any change in how DWARF-2 records are produced would require an update there and would cause compatibility problems with libgcc.a binaries already distributed; given that this is a static library a complex change involving function renames would likely be required. I propose therefore to accept the existing inconsistencies and deal with them entirely within GDB. I have figured out that the ISA bit lost in various places can still be recovered as long as we have symbol information -- that'll have the `st_other' attribute correctly set to one of standard MIPS/MIPS16/microMIPS encoding. Here's the resulting change. It adds a couple of new `gdbarch' hooks, one to update symbol information with the ISA bit lost in `_bfd_mips_elf_symbol_processing', and two other ones to adjust DWARF-2 records as they're processed. The ISA bit is set in each address handled according to information retrieved from the symbol table for the symbol spanning the address if any; limits are adjusted based on the address they point to related to the respective base address. Additionally minimal symbol information has to be adjusted accordingly in its gdbarch hook. With these changes in place some complications with ISA bit juggling in the PC that never fully worked can be removed from the MIPS backend. Conversely, the generic dynamic linker event special breakpoint symbol handler has to be updated to call the minimal symbol gdbarch hook to record that the symbol is a MIPS16 or microMIPS address if applicable or the breakpoint will be set at the wrong address and either fail to work or cause SIGTRAPs (this is because the symbol is handled early on and bypasses regular symbol processing). 4. Results obtained The change fixes the example above -- to repeat only the crucial steps: (gdb) break main Breakpoint 1 at 0x400491: file foobar.c, line 23. (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) print foo $1 = {int (void)} 0x400681 <foo> (gdb) set foop = bar (gdb) advance bar bar () at foobar.c:9 9 } (gdb) disassemble Dump of assembler code for function bar: => 0x0040068d <+0>: jr ra 0x0040068f <+2>: li v0,2 End of assembler dump.

[Inferior 1 (process 14128) exited with code 02] (gdb) -- excellent! The change removes about 90 failures per MIPS16 multilib in mips-sde-elf testing too, results for MIPS16 are now similar to that for standard MIPS; microMIPS results are a bit worse because of host-I/O problems in QEMU used instead of MIPSsim for microMIPS testing only: === gdb Summary === # of expected passes 14299 # of unexpected failures 187 # of expected failures 56 # of known failures 58 # of unresolved testcases 11 # of untested testcases 52 # of unsupported tests 174 MIPS16: === gdb Summary === # of expected passes 14298 # of unexpected failures 187 # of unexpected successes 2 # of expected failures 54 # of known failures 58 # of unresolved testcases 12 # of untested testcases 52 # of unsupported tests 174 microMIPS: === gdb Summary === # of expected passes 14149 # of unexpected failures 201 # of unexpected successes 2 # of expected failures 54 # of known failures 58 # of unresolved testcases 7 # of untested testcases 53 # of unsupported tests 175 2014-12-12 Maciej W.

MIPS: Keep the ISA bit in compressed code addresses 1. Background information The MIPS architecture, as originally designed and implemented in mid-1980s has a uniform instruction word size that is 4 bytes, naturally aligned. As such all MIPS instructions are located at addresses that have their bits #1 and #0 set to zeroes, and any attempt to execute an instruction from an address that has any of the two bits set to one causes an address error exception. This may for example happen when a jump-register instruction is executed whose register value used as the jump target has any of these bits set. Then in mid 1990s LSI sought a way to improve code density for their TinyRISC family of MIPS cores and invented an alternatively encoded instruction set in a joint effort with MIPS Technologies (then a subsidiary of SGI). The new instruction set has been named the MIPS16 ASE (Application-Specific Extension) and uses a variable instruction word size, which is 2 bytes (as the name of the ASE suggests) for most, but there are a couple of exceptions that take 4 bytes, and then most of the 2-byte instructions can be treated with a 2-byte extension prefix to expand the range of the immediate operands used. As a result instructions are no longer 4-byte aligned, instead they are aligned to a multiple of 2. That left the bit #0 still unused for code references, be it for the standard MIPS (i.e. as originally invented) or for the MIPS16 instruction set, and based on that observation a clever trick was invented that on one hand allowed the processor to be seamlessly switched between the two instruction sets at any time at the run time while on the other avoided the introduction of any special control register to do that. So it is the bit #0 of the instruction address that was chosen as the selector and named the ISA bit. Any instruction executed at an even address is interpreted as a standard MIPS instruction (the address still has to have its bit #1 clear), any instruction executed at an odd address is interpreted as a MIPS16 instruction. To switch between modes ordinary jump instructions are used, such as used for function calls and returns, specifically the bit #0 of the source register used in jump-register instructions selects the execution (ISA) mode for the following piece of code to be interpreted in. Additionally new jump-immediate instructions were added that flipped the ISA bit to select the opposite mode upon execution. They were considered necessary to avoid the need to make register jumps in all cases as the original jump-immediate instructions provided no way to change the bit #0 at all. This was all important for cases where standard MIPS and MIPS16 code had to be mixed, either for compatibility with the existing binary code base or to access resources not reachable from MIPS16 code (the MIPS16 instruction set only provides access to general-purpose registers, and not for example floating-point unit registers or privileged coprocessor 0 registers) -- pieces of code in the opposite mode can be executed as ordinary subroutine calls. A similar approach has been more recently adopted for the MIPS16 replacement instruction set defined as the so called microMIPS ASE. This is another instruction set encoding introduced to the MIPS architecture. Just like the MIPS16 ASE, the microMIPS instruction set uses a variable-length encoding, where each instruction takes a multiple of 2 bytes. The ISA bit has been reused and for microMIPS-capable processors selects between the standard MIPS and the microMIPS mode instead. 2. Statement of the problem To put it shortly, MIPS16 and microMIPS code pointers used by GDB are different to these observed at the run time. This results in the same expressions being evaluated producing different results in GDB and in the program being debugged. Obviously it's the results obtained at the run time that are correct (they define how the program behaves) and therefore by definition the results obtained in GDB are incorrect. A bit longer description will record that obviously at the run time the ISA bit has to be set correctly (refer to background information above if unsure why so) or the program will not run as expected. This is recorded in all the executable file structures used at the run time: the dynamic symbol table (but not always the static one!), the GOT, and obviously in all the addresses embedded in code or data of the program itself, calculated by applying the appropriate relocations at the static link time. While a program is being processed by GDB, the ISA bit is stripped off from any code addresses, presumably to make them the same as the respective raw memory byte address used by the processor to access the instruction in the instruction fetch access cycle. This stripping is actually performed outside GDB proper, in BFD, specifically _bfd_mips_elf_symbol_processing (elfxx-mips.c, see the piece of code at the very bottom of that function, starting with an: "If this is an odd-valued function symbol, assume it's a MIPS16 or microMIPS one." comment). This function is also responsible for symbol table dumps made by `objdump' too, so you'll never see the ISA bit reported there by that tool, you need to use `readelf'. This is however unlike what is ever done at the run time, the ISA bit once present is never stripped off, for example a cast like this: (short *) main will not strip the ISA bit off and if the resulting pointer is intended to be used to access instructions as data, for example for software instruction decoding (like for fault recovery or emulation in a signal handler) or for self-modifying code then the bit still has to be stripped off by an explicit AND operation. This is probably best illustrated with a simple real program example. Let's consider the following simple program: $ cat foobar.c int __attribute__ ((mips16)) foo (void) { return 1; } int __attribute__ ((mips16)) bar (void) { return 2; } int __attribute__ ((nomips16)) foo32 (void) { return 3; } int (*foo32p) (void) = foo32; int (*foop) (void) = foo; int fooi = (int) foo; int main (void) { return foop (); } $ This is plain C with no odd tricks, except from the instruction mode attributes. They are not necessary to trigger this problem, I just put them here so that the program can be contained in a single source file and to make it obvious which function is MIPS16 code and which is not. Let's try it with Linux, so that everyone can repeat this experiment: $ mips-linux-gnu-gcc -mips16 -g -O2 -o foobar foobar.c $ Let's have a look at some interesting symbols: $ mips-linux-gnu-readelf -s foobar | egrep 'table|foo|bar' Symbol table '.dynsym' contains 7 entries: Symbol table '.symtab' contains 95 entries: 55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c 66: 0040068c 4 FUNC GLOBAL DEFAULT [MIPS16] 12 bar 68: 00410848 4 OBJECT GLOBAL DEFAULT 21 foo32p 70: 00410844 4 OBJECT GLOBAL DEFAULT 21 foop 78: 00400684 8 FUNC GLOBAL DEFAULT 12 foo32 80: 00400680 4 FUNC GLOBAL DEFAULT [MIPS16] 12 foo 88: 00410840 4 OBJECT GLOBAL DEFAULT 21 fooi $ Hmm, no sight of the ISA bit, but notice how foo and bar (but not foo32!) have been marked as MIPS16 functions (ELF symbol structure's `st_other' field is used for that). So let's try to run and poke at this program with GDB. I'll be using a native system for simplicity (I'll be using ellipses here and there to remove unrelated clutter): $ ./foobar $ echo $? 1 $ So far, so good. $ gdb ./foobar [...] (gdb) break main Breakpoint 1 at 0x400490: file foobar.c, line 23. (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) Yay, it worked! OK, so let's poke at it: (gdb) print main $1 = {int (void)} 0x400490 <main> (gdb) print foo32 $2 = {int (void)} 0x400684 <foo32> (gdb) print foo32p $3 = (int (*)(void)) 0x400684 <foo32> (gdb) print bar $4 = {int (void)} 0x40068c <bar> (gdb) print foo $5 = {int (void)} 0x400680 <foo> (gdb) print foop $6 = (int (*)(void)) 0x400681 <foo> (gdb) A-ha!

(gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) Actually we do not like to run foo here at all. Let's run bar instead! (gdb) set foop = bar (gdb) print foop $10 = (int (*)(void)) 0x40068c <bar> (gdb) Hmm, no ISA bit. Is it going to work?

(gdb) continue Continuing. Program terminated with signal SIGILL, Illegal instruction. The program no longer exists. (gdb) So let's try something else: (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) set foop = foo (gdb) advance foo foo () at foobar.c:4 4 } (gdb) disassemble Dump of assembler code for function foo: => 0x00400680 <+0>: jr ra 0x00400682 <+2>: li v0,1 End of assembler dump.

[Inferior 1 (process 14113) exited with code 03] (gdb) That did work though, so it's the ISA bit only! (gdb) quit Enough! That's the tip of the iceberg only though. So let's rebuild the executable with some dynamic symbols: $ mips-linux-gnu-gcc -mips16 -Wl,--export-dynamic -g -O2 -o foobar-dyn foobar.c $ mips-linux-gnu-readelf -s foobar-dyn | egrep 'table|foo|bar' Symbol table '.dynsym' contains 32 entries: 6: 004009cd 4 FUNC GLOBAL DEFAULT 12 bar 8: 00410b88 4 OBJECT GLOBAL DEFAULT 21 foo32p 9: 00410b84 4 OBJECT GLOBAL DEFAULT 21 foop 15: 004009c4 8 FUNC GLOBAL DEFAULT 12 foo32 17: 004009c1 4 FUNC GLOBAL DEFAULT 12 foo 25: 00410b80 4 OBJECT GLOBAL DEFAULT 21 fooi Symbol table '.symtab' contains 95 entries: 55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c 69: 004009cd 4 FUNC GLOBAL DEFAULT 12 bar 71: 00410b88 4 OBJECT GLOBAL DEFAULT 21 foo32p 72: 00410b84 4 OBJECT GLOBAL DEFAULT 21 foop 79: 004009c4 8 FUNC GLOBAL DEFAULT 12 foo32 81: 004009c1 4 FUNC GLOBAL DEFAULT 12 foo 89: 00410b80 4 OBJECT GLOBAL DEFAULT 21 fooi $ OK, now the ISA bit is there for a change, but the MIPS16 `st_other' attribute gone, hmm...

However it's not always right for some reason, I don't have a small test case to show it, but here's an excerpt from MIPS16 libc, a prologue of a function: 00019630 <__libc_init_first>: 19630: e8a0 jrc ra 19632: 6500 nop 00019634 <_init>: 19634: f000 6a11 li v0,17 19638: f7d8 0b08 la v1,15e00 <_DYNAMIC+0x15c54> 1963c: f400 3240 sll v0,16 19640: e269 addu v0,v1 19642: 659a move gp,v0 19644: 64f6 save 48,ra,s0-s1 19646: 671c move s0,gp 19648: d204 sw v0,16(sp) 1964a: f352 984c lw v0,-27828(s0) 1964e: 6724 move s1,a0 and the corresponding DWARF-2 line info: Line Number Statements: Extended opcode 2: set Address to 0x19631 Advance Line by 44 to 45 Copy Special opcode 8: advance Address by 0 to 0x19631 and Line by 3 to 48 Special opcode 66: advance Address by 4 to 0x19635 and Line by 5 to 53 Advance PC by constant 17 to 0x19646 Special opcode 25: advance Address by 1 to 0x19647 and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 33: advance Address by 2 to 0x19649 and Line by 0 to 53 Special opcode 39: advance Address by 2 to 0x1964b and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 61: advance Address by 4 to 0x1964f and Line by 0 to 53 -- see that "Advance PC by constant 17" there? It clears the ISA bit, however code at 0x19646 is not standard MIPS code at all. For some reason the constant is always 17, I've never seen DW_LNS_const_add_pc used with any other value -- is that a binutils bug or what? 3. Solution: I think we should retain the value of the ISA bit in code references, that is effectively treat them as cookies as they indeed are (although trivially calculated) rather than raw memory byte addresses. In a perfect world both the static symbol table and the respective DWARF-2 records should be fixed to include the ISA bit in all the cases. I think however that this is infeasible. All the uses of `_bfd_mips_elf_symbol_processing' can not necessarily be tracked down. This function is used by `elf_slurp_symbol_table' that in turn is used by `bfd_canonicalize_symtab' and `bfd_canonicalize_dynamic_symtab', which are public interfaces. Similarly DWARF-2 records are used outside GDB, one notable if a bit questionable is the exception unwinder (libgcc/unwind-dw2.c) -- I have identified at least bits in `execute_cfa_program' and `uw_frame_state_for', both around the calls to `_Unwind_IsSignalFrame', that would need an update as they effectively flip the ISA bit freely; see also the comment about MASK_RETURN_ADDR in gcc/config/mips/mips.h. But there may be more places. Any change in how DWARF-2 records are produced would require an update there and would cause compatibility problems with libgcc.a binaries already distributed; given that this is a static library a complex change involving function renames would likely be required. I propose therefore to accept the existing inconsistencies and deal with them entirely within GDB. I have figured out that the ISA bit lost in various places can still be recovered as long as we have symbol information -- that'll have the `st_other' attribute correctly set to one of standard MIPS/MIPS16/microMIPS encoding. Here's the resulting change. It adds a couple of new `gdbarch' hooks, one to update symbol information with the ISA bit lost in `_bfd_mips_elf_symbol_processing', and two other ones to adjust DWARF-2 records as they're processed. The ISA bit is set in each address handled according to information retrieved from the symbol table for the symbol spanning the address if any; limits are adjusted based on the address they point to related to the respective base address. Additionally minimal symbol information has to be adjusted accordingly in its gdbarch hook. With these changes in place some complications with ISA bit juggling in the PC that never fully worked can be removed from the MIPS backend. Conversely, the generic dynamic linker event special breakpoint symbol handler has to be updated to call the minimal symbol gdbarch hook to record that the symbol is a MIPS16 or microMIPS address if applicable or the breakpoint will be set at the wrong address and either fail to work or cause SIGTRAPs (this is because the symbol is handled early on and bypasses regular symbol processing). 4. Results obtained The change fixes the example above -- to repeat only the crucial steps: (gdb) break main Breakpoint 1 at 0x400491: file foobar.c, line 23. (gdb) run Starting program: .../foobar Breakpoint 1, main () at foobar.c:23 23 return foop (); (gdb) print foo $1 = {int (void)} 0x400681 <foo> (gdb) set foop = bar (gdb) advance bar bar () at foobar.c:9 9 } (gdb) disassemble Dump of assembler code for function bar: => 0x0040068d <+0>: jr ra 0x0040068f <+2>: li v0,2 End of assembler dump.

MIPS: Keep the ISA bit in compressed code addresses 1. Background information The MIPS architecture, as originally designed and implemented in mid-1980s has a uniform instruction word size that is 4 bytes, naturally aligned. As such all MIPS instructions are located at addresses that have their bits #1 and #0 set to zeroes, and any attempt to execute an instruction from an address that has any of the two bits set to one causes an address error exception. This may for example happen when a jump-register instruction is executed whose register value used as the jump target has any of these bits set. Then in mid 1990s LSI sought a way to improve code density for their TinyRISC family of MIPS cores and invented an alternatively encoded instruction set in a joint effort with MIPS Technologies (then a subsidiary of SGI). The new instruction set has been named the MIPS16 ASE (Application-Specific Extension) and uses a variable instruction word size, which is 2 bytes (as the name of the ASE suggests) for most, but there are a couple of exceptions that take 4 bytes, and then most of the 2-byte instructions can be treated with a 2-byte extension prefix to expand the range of the immediate operands used. As a result instructions are no longer 4-byte aligned, instead they are aligned to a multiple of 2. That left the bit #0 still unused for code references, be it for the standard MIPS (i.e. as originally invented) or for the MIPS16 instruction set, and based on that observation a clever trick was invented that on one hand allowed the processor to be seamlessly switched between the two instruction sets at any time at the run time while on the other avoided the introduction of any special control register to do that. So it is the bit #0 of the instruction address that was chosen as the selector and named the ISA bit. Any instruction executed at an even address is interpreted as a standard MIPS instruction (the address still has to have its bit #1 clear), any instruction executed at an odd address is interpreted as a MIPS16 instruction. To switch between modes ordinary jump instructions are used, such as used for function calls and returns, specifically the bit #0 of the source register used in jump-register instructions selects the execution (ISA) mode for the following piece of code to be interpreted in. Additionally new jump-immediate instructions were added that flipped the ISA bit to select the opposite mode upon execution. They were considered necessary to avoid the need to make register jumps in all cases as the original jump-immediate instructions provided no way to change the bit #0 at all. This was all important for cases where standard MIPS and MIPS16 code had to be mixed, either for compatibility with the existing binary code base or to access resources not reachable from MIPS16 code (the MIPS16 instruction set only provides access to general-purpose registers, and not for example floating-point unit registers or privileged coprocessor 0 registers) -- pieces of code in the opposite mode can be executed as ordinary subroutine calls. A similar approach has been more recently adopted for the MIPS16 replacement instruction set defined as the so called microMIPS ASE. This is another instruction set encoding introduced to the MIPS architecture. Just like the MIPS16 ASE, the microMIPS instruction set uses a variable-length encoding, where each instruction takes a multiple of 2 bytes. The ISA bit has been reused and for microMIPS-capable processors selects between the standard MIPS and the microMIPS mode instead. 2. Statement of the problem To put it shortly, MIPS16 and microMIPS code pointers used by GDB are different to these observed at the run time. This results in the same expressions being evaluated producing different results in GDB and in the program being debugged. Obviously it's the results obtained at the run time that are correct (they define how the program behaves) and therefore by definition the results obtained in GDB are incorrect. A bit longer description will record that obviously at the run time the ISA bit has to be set correctly (refer to background information above if unsure why so) or the program will not run as expected. This is recorded in all the executable file structures used at the run time: the dynamic symbol table (but not always the static one!), the GOT, and obviously in all the addresses embedded in code or data of the program itself, calculated by applying the appropriate relocations at the static link time. While a program is being processed by GDB, the ISA bit is stripped off from any code addresses, presumably to make them the same as the respective raw memory byte address used by the processor to access the instruction in the instruction fetch access cycle. This stripping is actually performed outside GDB proper, in BFD, specifically _bfd_mips_elf_symbol_processing (elfxx-mips.c, see the piece of code at the very bottom of that function, starting with an: "If this is an odd-valued function symbol, assume it's a MIPS16 or microMIPS one." comment). This function is also responsible for symbol table dumps made by `objdump' too, so you'll never see the ISA bit reported there by that tool, you need to use `readelf'. This is however unlike what is ever done at the run time, the ISA bit once present is never stripped off, for example a cast like this: (short *) main will not strip the ISA bit off and if the resulting pointer is intended to be used to access instructions as data, for example for software instruction decoding (like for fault recovery or emulation in a signal handler) or for self-modifying code then the bit still has to be stripped off by an explicit AND operation. This is probably best illustrated with a simple real program example. Let's consider the following simple program: $ cat foobar.c int __attribute__ ((mips16)) foo (void) { return 1; } int __attribute__ ((mips16)) bar (void) { return 2; } int __attribute__ ((nomips16)) foo32 (void) { return 3; } int (*foo32p) (void) = foo32; int (*foop) (void) = foo; int fooi = (int) foo; int main (void) { return foop (); } $ This is plain C with no odd tricks, except from the instruction mode attributes. They are not necessary to trigger this problem, I just put them here so that the program can be contained in a single source file and to make it obvious which function is MIPS16 code and which is not. Let's try it with Linux, so that everyone can repeat this experiment: $ mips-linux-gnu-gcc -mips16 -g -O2 -o foobar foobar.c $ Let's have a look at some interesting symbols: $ mips-linux-gnu-readelf -s foobar | egrep 'table|foo|bar' Symbol table '.dynsym' contains 7 entries: Symbol table '.symtab' contains 95 entries: 55: 00000000 0 FILE LOCAL DEFAULT ABS foobar.c 66: 0040068c 4 FUNC GLOBAL DEFAULT [MIPS16] 12 bar 68: 00410848 4 OBJECT GLOBAL DEFAULT 21 foo32p 70: 00410844 4 OBJECT GLOBAL DEFAULT 21 foop 78: 00400684 8 FUNC GLOBAL DEFAULT 12 foo32 80: 00400680 4 FUNC GLOBAL DEFAULT [MIPS16] 12 foo 88: 00410840 4 OBJECT GLOBAL DEFAULT 21 fooi $ Hmm, no sight of the ISA bit, but notice how foo and bar (but not foo32!) have been marked as MIPS16 functions (ELF symbol structure's `st_other' field is used for that). So let's try to run and poke at this program with GDB. I'll be using a native system for simplicity (I'll be using ellipses here and there to remove unrelated clutter): $ ./foobar $ echo $? 1 $ So far, so good. $ gdb ./foobar [...] (gdb) break main Breakpoint 1 at 0x400490: file foobar.c, line 23.

However it's not always right for some reason, I don't have a small test case to show it, but here's an excerpt from MIPS16 libc, a prologue of a function: 00019630 <__libc_init_first>: 19630: e8a0 jrc ra 19632: 6500 nop 00019634 <_init>: 19634: f000 6a11 li v0,17 19638: f7d8 0b08 la v1,15e00 <_DYNAMIC+0x15c54> 1963c: f400 3240 sll v0,16 19640: e269 addu v0,v1 19642: 659a move gp,v0 19644: 64f6 save 48,ra,s0-s1 19646: 671c move s0,gp 19648: d204 sw v0,16(sp) 1964a: f352 984c lw v0,-27828(s0) 1964e: 6724 move s1,a0 and the corresponding DWARF-2 line info: Line Number Statements: Extended opcode 2: set Address to 0x19631 Advance Line by 44 to 45 Copy Special opcode 8: advance Address by 0 to 0x19631 and Line by 3 to 48 Special opcode 66: advance Address by 4 to 0x19635 and Line by 5 to 53 Advance PC by constant 17 to 0x19646 Special opcode 25: advance Address by 1 to 0x19647 and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 33: advance Address by 2 to 0x19649 and Line by 0 to 53 Special opcode 39: advance Address by 2 to 0x1964b and Line by 6 to 59 Advance Line by -6 to 53 Special opcode 61: advance Address by 4 to 0x1964f and Line by 0 to 53 -- see that "Advance PC by constant 17" there? It clears the ISA bit, however code at 0x19646 is not standard MIPS code at all. For some reason the constant is always 17, I've never seen DW_LNS_const_add_pc used with any other value -- is that a binutils bug or what? 3. Solution: I think we should retain the value of the ISA bit in code references, that is effectively treat them as cookies as they indeed are (although trivially calculated) rather than raw memory byte addresses. In a perfect world both the static symbol table and the respective DWARF-2 records should be fixed to include the ISA bit in all the cases. I think however that this is infeasible. All the uses of `_bfd_mips_elf_symbol_processing' can not necessarily be tracked down. This function is used by `elf_slurp_symbol_table' that in turn is used by `bfd_canonicalize_symtab' and `bfd_canonicalize_dynamic_symtab', which are public interfaces. Similarly DWARF-2 records are used outside GDB, one notable if a bit questionable is the exception unwinder (libgcc/unwind-dw2.c) -- I have identified at least bits in `execute_cfa_program' and `uw_frame_state_for', both around the calls to `_Unwind_IsSignalFrame', that would need an update as they effectively flip the ISA bit freely; see also the comment about MASK_RETURN_ADDR in gcc/config/mips/mips.h. But there may be more places. Any change in how DWARF-2 records are produced would require an update there and would cause compatibility problems with libgcc.a binaries already distributed; given that this is a static library a complex change involving function renames would likely be required. I propose therefore to accept the existing inconsistencies and deal with them entirely within GDB. I have figured out that the ISA bit lost in various places can still be recovered as long as we have symbol information -- that'll have the `st_other' attribute correctly set to one of standard MIPS/MIPS16/microMIPS encoding. Here's the resulting change. It adds a couple of new `gdbarch' hooks, one to update symbol information with the ISA bit lost in `_bfd_mips_elf_symbol_processing', and two other ones to adjust DWARF-2 records as they're processed. The ISA bit is set in each address handled according to information retrieved from the symbol table for the symbol spanning the address if any; limits are adjusted based on the address they point to related to the respective base address. Additionally minimal symbol information has to be adjusted accordingly in its gdbarch hook. With these changes in place some complications with ISA bit juggling in the PC that never fully worked can be removed from the MIPS backend. Conversely, the generic dynamic linker event special breakpoint symbol handler has to be updated to call the minimal symbol gdbarch hook to record that the symbol is a MIPS16 or microMIPS address if applicable or the breakpoint will be set at the wrong address and either fail to work or cause SIGTRAPs (this is because the symbol is handled early on and bypasses regular symbol processing). 4. Results obtained The change fixes the example above -- to repeat only the crucial steps: (gdb) break main Breakpoint 1 at 0x400491: file foobar.c, line 23.

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

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

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.
