Subject: decl2.c (setup_initp): Give statics with no priority the default priority here.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c2a0097066b2f122d4ae0a70bde6e8f1721081a;p=platform%2Fupstream%2Fgcc.git

decl2.c (setup_initp): Give statics with no priority the default priority here.

	* decl2.c (setup_initp): Give statics with no priority the default
	priority here.
	(do_dtors, do_ctors, finish_file): Remove special handling of
	non-prioritized statics.
