Fix a commit cd6c3b4ffc ("New gdbarch methods breakpoint_kind_from_pc
and sw_breakpoint_from_kind") regression and restore the use of
`->placed_address' rather than `->reqstd_address' as the location for a
memory breakpoint to be inserted at. Previously
`gdbarch_breakpoint_from_pc' was used that made that adjustment in
`default_memory_insert_breakpoint' from the preinitialized value,
however with the said commit that call is gone, so the passed
`->placed_address' has to be used for the initialization.
The regression manifests itself as the inability to debug any MIPS/Linux
compressed ISA dynamic executable as GDB corrupts the dynamic loader
with one of its implicit breakpoints, causing the program to crash, as
seen for example with the `mips-linux-gnu' target, o32 ABI, MIPS16 code,
and the gdb.base/advance.exp test case:

Fix `set architecture' and `set endian' command disassembly regressions

well as a MIPS compressed ISA disassembly target regression from commit

As an update to commit ede5f15146 ("gdbarch.h: Change
gdbarch_info::tdep_info's type to void *") replace the definition of the
`tdep_info' member in `struct gdbarch_info' with an anonymous union,
comprising the original member, with its type reverted to `struct
gdbarch_tdep_info *', a `tdesc_data' member of a `struct tdesc_arch_data

When --no-define-common is used to build shared library, treat common
symbol as undefined so that common symbols that are referenced from a
shared library to be assigned addresses only in the main program. This
eliminates the unused duplicate space in the shared library, and also
prevents any possible confusion over resolving to the wrong duplicate
when there are many dynamic modules with specialized search paths for
runtime symbol resolution.
--no-define-common is only allowed when building a shared library.

I ran the gdb.rust tests against Rust 1.20 (beta) and saw a few
failures. The failures all came because a particular item moved to a
different module. Since the particular choice of module name isn't
important here, I simply widened the allowable results.

during the parse.

(execute_user_command): Update.
This patch introduces the use of various containers -- std::vector,
std::string, or gdb::byte_vector -- in several spots in gdb that were
using xmalloc and a cleanup.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* valops.c (search_struct_method): Use gdb::byte_vector.
* valarith.c (value_concat): Use std::vector.
* target.c (memory_xfer_partial): Use gdb::byte_vector.
(simple_search_memory): Likewise.
* printcmd.c (find_string_backward): Use gdb::byte_vector.
* mi/mi-main.c (mi_cmd_data_write_memory): Use gdb::byte_vector.
* gcore.c (gcore_copy_callback): Use gdb::byte_vector.
* elfread.c (elf_rel_plt_read): Use std::string.
* cp-valprint.c (cp_print_value): Use gdb::byte_vector.
* cli/cli-dump.c (restore_section_callback): Use
gdb::byte_vector.
This removes some cleanups from jit.c by using unique_xmalloc_ptr
instead.
ChangeLog

* jit.c (jit_reader_load_command): Use unique_xmalloc_ptr.
This patch replaces tui_restore_gdbout (a cleaup function) with a use
of scoped_restore. This one is broken out into its own patch because
it might slightly change the behavior of gdb: it saves and restores
pagination_enabled, whereas the tui_restore_gdbout unconditionally set
pagination_enabled to 1; and I think this warrants closer review.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* tui/tui-regs.c (tui_restore_gdbout): Remove.
(tui_register_format): Use scoped_restore.
There were a few more places in gdb that could easily use
scoped_restore, replacing some cleanups.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* reverse.c (exec_direction_default): Remove.
(exec_reverse_once): Use scoped_restore.
* remote.c (restore_remote_timeout): Remove.
(remote_flash_erase, remote_flash_write, remote_flash_done)
(readchar, remote_serial_write): Use scoped_restore.
* cli/cli-script.c (struct source_cleanup_lines_args)
(source_cleanup_lines): Remove.
(script_from_file): Use scoped_restore.
* cli/cli-cmds.c (source_verbose_cleanup): Remove.
(source_command): Use scoped_restore.
make_cleanup_free_so is used in a single spot. This patch introduces
a unique pointer wrapper for struct so_list, and changes this spot to
use it.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* utils.h (make_cleanup_free_so): Remove.
* utils.c (do_free_so, make_cleanup_free_so): Remove.
* solist.h (struct so_deleter): New.
(so_list_up): New typedef.
* solib-svr4.c (svr4_read_so_list): Use so_list_up.
This patch replaces make_cleanup_restore_current_language with an RAII
class that saves the current language, and restores it when the object
is destroyed.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* utils.h (make_cleanup_restore_current_language): Remove.
* utils.c (do_restore_current_language)
(make_cleanup_restore_current_language): Remove.
* parse.c (parse_exp_in_context_1)
(parse_expression_with_language): Use
scoped_restore_current_language.
* mi/mi-main.c (mi_cmd_execute): Use
scoped_restore_current_language.
* language.h (scoped_restore_current_language): New class.
compile/compile.c had its own cleanup to unlink a file. This patch
replaces this cleanup with gdb::unlinker.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* compile/compile.c (cleanup_unlink_file): Remove.
(compile_to_object): Use gdb::unlinker.
(eval_compile_command): Likewise.
After the preceding patches, make_cleanup_fclose is no longer used, so
remove it.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* utils.h (make_cleanup_fclose): Remove.
* utils.c (do_fclose_cleanup, make_cleanup_fclose): Remove.
This changes open_terminal_stream to return a gdb_file_up, eliminating
another use of make_cleanup_fclose. Arguably perhaps new_ui should
take ownership of the files using a move, but there is at least one
spot where this isn't appropriate (or at least not currently done), so
I elected to use a more minimal approach.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* top.c (open_terminal_stream): Return gdb_file_up.
(new_ui_command): Update.
This changes some functions in source.c to use gdb_file_up.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* source.c (print_source_lines_base, forward_search_command)
(reverse_search_command): Use gdb_file_up.
This updates fbsd-nat.c to use gdb_file_up. This removes a use of a
cleanup, and helps remove make_cleanup_fclose in a later patch.
I have no way to test this patch.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* fbsd-nat.c (fbsd_find_memory_regions): Update.
This changes find_and_open_script to return a
gdb::optional<open_script>, where open_script is a new type
encapsulating the two return values. The new type helps avoid
cleanups in the callers.
ChangeLog
2017-08-03 Tom Tromey <tom@tromey.com>
* cli/cli-cmds.c (find_and_open_script): Change return type.
Remove "streamp" and "full_path" parameters.
(source_script_with_search): Update.
* auto-load.c (source_script_file): Update.
* cli/cli-cmds.h (find_and_open_script): Change type.
(open_script): New struct.
