Subject: 	* utils.c (prompt_for_continue_wait_time): New static global.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=260c0b2ad484ea2c5d9a6af1d756ac15c936f9d2;p=binutils-gdb.git

	* utils.c (prompt_for_continue_wait_time): New static global.
	(make_command_stats_cleanup): Initialize it.
	(report_command_stats): Subtract time waiting for user.
	(prompt_for_continue): Track time waiting for user.
	(defaulted_query): Track time waiting for user.
