Subject: When reverse-stepping, only insert a resume breakpoint at ecs->stop_func_start
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58c48e7253d94d36e3119134b0c41a99088bae89;p=binutils-gdb.git

When reverse-stepping, only insert a resume breakpoint at ecs->stop_func_start
if the function start is known.  Otherwise, keep single-stepping.
