Subject: d: Use d_comdat_linkage on generated internal decl.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=48742e02d7136e60e8e91631d76403d56e4eee09;p=gcc.git

d: Use d_comdat_linkage on generated internal decl.

This adds weak linkage to internal TypeInfo data on top of the existing
DECL_COMDAT, which helps in the unlikely event that two of the same
TypeInfo data ends up in multiple places.

gcc/d/ChangeLog:

	* typeinfo.cc (TypeInfoVisitor::internal_reference): Call
	d_comdat_linkage on generated decl.
