Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files. Tested by the buildbot. gdb/ChangeLog 2019-03-13 Tom Tromey <tromey@adacore.com> * i386-gnu-nat.c (i386_gnu_nat_target::fetch_registers) (i386_gnu_nat_target::store_registers): Update. * target-debug.h (target_debug_print_std_string): New macro. * x86-linux-nat.c (x86_linux_nat_target::enable_btrace): Update. * windows-tdep.c (display_one_tib): Update. * tui/tui-stack.c (tui_make_status_line): Update. * top.c (print_inferior_quit_action): Update. * thread.c (thr_try_catch_cmd): Update.

|
On Windows, the system behaves a little differently when two
|
|
objfiles each define a global symbol using the same name, compared
|
|
to other platforms such as GNU/Linux for instance. On GNU/Linux,
|
|
all instances of the symbol effectively get merged into a single
|
|
one, but on Windows, they remain distinct.
|
|
|
|
As a result, it usually makes sense to start global symbol searches
|
|
with the current objfile before expanding it to all other objfiles.
|
|
This helps for instance when a user debugs some code in a DLL that
|
|
refers to a global variable defined inside that DLL. When trying
|
|
to print the value of that global variable, it would be unhelpful
|
|
to print the value of another global variable defined with the same
|
|
name, but in a different DLL. */
