From 1f9d9e321ca0416d970a8a4ae94df69de0e22d14 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Thu, 21 Apr 2022 15:09:17 +0100 Subject: gdb: add some additional thread status debug output While working on this patch: https://sourceware.org/pipermail/gdb-patches/2022-January/185109.html I found it really useful to print the executing/resumed status of all threads (or all threads in a particular inferior) at various places (e.g. when a new inferior is started, when GDB attaches, etc). This debug was originally part of the above patch, but I wanted to rewrite this as a separate patch and move the code into a new function in infrun.h, which is what this patch does. Unless 'set debug infrun on' is in effect, then there should be no user visible changes after this commit. --- gdb/infrun.h | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) (limited to 'gdb/infrun.h') diff --git a/gdb/infrun.h b/gdb/infrun.h index 9685f3a..0c7c55e 100644 --- a/gdb/infrun.h +++ b/gdb/infrun.h @@ -48,6 +48,32 @@ extern bool debug_infrun; #define INFRUN_SCOPED_DEBUG_ENTER_EXIT \ scoped_debug_enter_exit (debug_infrun, "infrun") +/* A infrun debug helper routine to print out all the threads in the set + THREADS (which should be a range type that returns thread_info* + objects). + + The TITLE is a string that is printed before the list of threads. + + Output is only produced when 'set debug infrun on'. */ + +template +static inline void +infrun_debug_show_threads (const char *title, ThreadRange threads) +{ + if (debug_infrun) + { + infrun_debug_printf ("%s:", title); + for (thread_info *thread : threads) + infrun_debug_printf (" thread %s, executing = %d, resumed = %d, " + "state = %s", + thread->ptid.to_string ().c_str (), + thread->executing (), + thread->resumed (), + thread_state_string (thread->state)); + } +} + + /* Nonzero if we want to give control to the user when we're notified of shared library events by the dynamic linker. */ extern int stop_on_solib_events; -- cgit v1.1
