Subject: [patch] fix PR43602 for emutls targets.

The fix for profiling race conditions applied as r157822 revealed an issue with emutls: This patch allows r157822 to be applied without regression on emutls targets.

The patch needs review from someone more familiar with emutls - although it has been tested on a variety of targets

(the discussion of this fix got attached to PR43553, for no well- explored reason - I would expect that PR43553 can be closed by this patch too).


	PR middle-end/PR43602
	* gcc/varasm.c:
	(get_emutls_init_templ_addr): Copy DECL_VISIBILITY_SPECIFIED.
	(emutls_decl): Ditto.
	(emutls_finalize_control_vars): New Proc.
	(emutls_finalize_control_vars_1): New Callback.
	* gcc/toplev.c: Call emutls_finalize_control_vars() for emutls targets.
	* gcc/output.h: Declare emutls_finalize_control_vars().


changelog and patch attached.
Iain
