Subject: Remove workaround allowing interposition of nested functions.
X-Git-Tag: upstream/12.2.0~3690
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d44d791012efda1f48ed647d1d3a1538d15d4e19;p=platform%2Fupstream%2Fgcc.git

Remove workaround allowing interposition of nested functions.

	* gimple.c (gimple_call_static_chain_flags): Revert the workaround
	allowing interposition since issues with binds_to_local_def were
	hopefully solved.
