From ee8b88452c1cb1be97199942aee7a76bbca210ee Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 28 Aug 2021 20:38:27 -0600 Subject: [PATCH] Add a show function for "maint show worker-threads" I wanted to see how many threads gdb thought it was using, but "maint show worker-threads" only reported "unlimited". This patch adds a show function so that it will now report the number of threads gdb has started. Regression tested on x86-64 Fedora 34. --- gdb/maint.c | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) diff --git a/gdb/maint.c b/gdb/maint.c index 4637fcbc86c..cbd7d4ed47b 100644 --- a/gdb/maint.c +++ b/gdb/maint.c @@ -866,6 +866,21 @@ maintenance_set_worker_threads (const char *args, int from_tty, update_thread_pool_size (); } +static void +maintenance_show_worker_threads (struct ui_file *file, int from_tty, + struct cmd_list_element *c, + const char *value) +{ + if (n_worker_threads == -1) + fprintf_filtered (file, _("The number of worker threads GDB " + "can use is unlimited (currently %zu).\n"), + gdb::thread_pool::g_thread_pool->thread_count ()); + else + fprintf_filtered (file, _("The number of worker threads GDB " + "can use is %d.\n"), + n_worker_threads); +} + /* If true, display time usage both at startup and for each command. */ @@ -1371,7 +1386,8 @@ Set the number of worker threads GDB can use."), _("\ Show the number of worker threads GDB can use."), _("\ GDB may use multiple threads to speed up certain CPU-intensive operations,\n\ such as demangling symbol names."), - maintenance_set_worker_threads, NULL, + maintenance_set_worker_threads, + maintenance_show_worker_threads, &maintenance_set_cmdlist, &maintenance_show_cmdlist); -- 2.30.2
