Subject: 	* lto.c (lto_materialize_function): Announce function when
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1375c6f8ee50f0882e3bec39b0ce9e97d40c9434;p=thirdparty%2Fgcc.git

	* lto.c (lto_materialize_function): Announce function when
	reading body; allocate_struct_function only when reading body;
	do not finalize local statics; ggc_collect after reading;
	do not mark reachable node.
	(materialize_cgraph): Do not announce function.
