Subject: debug/123886 - remove GTY((skip)) from external_die_map entry
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2b44a1ab15cfd0936860bbb78ece649e9b5ca0a0;p=thirdparty%2Fgcc.git

debug/123886 - remove GTY((skip)) from external_die_map entry

The following avoids GCing IDENTIFIER_POINTERs referenced from
external_die_map after we clear ggc_protect_identifiers.  I never
expected those to be GCed.

	PR debug/123886
	* dwarf2out.cc (sym_off_pair::sym): Remove GTY((skip)).
