Subject: Change backtrace_command_1 calling to use flags
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1cf7e64086d1490649dc56e1c0505be91c600218;p=binutils-gdb.git

Change backtrace_command_1 calling to use flags

The next patch will add more flags to backtrace_command_1; and rather
than add another boolean argument, this patch changes it to accept a
flags value.

2018-03-26  Tom Tromey  <tom@tromey.com>

	* stack.c (backtrace_command_1): Remove "show_locals" parameter,
	add "flags".
	(backtrace_command): Remove "fulltrace", add "flags".
