Subject: 	* corelow.c (get_core_registers):  Initialize cf.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=95b71071825df95482061f9e942be6615ad28303;p=binutils-gdb.git

	* corelow.c (get_core_registers):  Initialize cf.

	* procfs.c:  Minor changes to make pre-ANSI compilers happy.
	(procfs_notice_signals):  Copy traced signal set back to
	pi->prrun.pr_trace.
	(unconditionally_kill_inferior):  If PR_DEAD is defined,
	rerun inferior after killing it.
