Subject: 	* fork-child.c (startup_inferior): Only set threads not-executing
X-Git-Tag: sid-snapshot-20081201~288
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2e979b9404414113dc61b32eebcda8a53632605c;p=external%2Fbinutils.git

	* fork-child.c (startup_inferior): Only set threads not-executing
	after getting all the pending execs.  On TARGET_WAITKIND_IGNORE,
	keep waiting, don't resume.  On all other cases but
	TARGET_WAITKIND_SIGNALLED and TARGET_WAITKIND_EXITED, switch to
	the event ptid.
